You know exercise builds muscles, strengthens bones, keeps your heart healthy and your mind sharp. But it also does something that you might not think much about: It helps keep your immune system â your internal defenses against infection â in tip-top shape.
If you take time for some physical exertion each day, it helps get your body ready to attack bacteria, viruses and toxins that can sneak in and make you sick.
But how much exercise is effective? Do too little or too much, and it wonât have the best effect on your immune system.
Clinical immunologist  Leonard Calabrese, DO, answers common questions about how exercise can impact your immunity and how to use your workouts to shut out a world of would-be invaders.
Q: How does breaking a sweat boost immunity?
A:Â If you exercise moderately on a regular basis, it tunes up the immune system in many ways. It enhances your broad-based defenses against viral infections, such as those causing upper respiratory infections.
Working out regularly also reduces the risk of many chronic diseases such as cardiovascular, respiratory illnesses and metabolic diseases, such as type 2 diabetes.
Q: How much exercise do you need?
A:Â Fortunately, you donât have to push yourself to the limit to rev up your immune system. In fact, your immune system needs less of a workout than you get with your average cardio routine.
Focus on getting 20-30 minutes of moderate exercise, five days a week, and your immune system will thank you.
Q: What types of exercise are most helpful?
A:Â Moderate exercises, including biking or walking briskly in your neighborhood, are good ways to get your blood flowing. Swimming is also a good option for non-weight-bearing exercise for your joints.
Also try mind-body exercises such as Tai-Chi, Qi Gong and yoga, which are all options that help keep your joints flexible. These exercises also reduce chronic stress, which in itself is a powerful immune booster. These exercises can also help alleviate osteoarthritis and fibromyalgia symptoms.
Q: Can too much exercise set your immune system back?
A:Â Yes, though, the level to which it can slow your system down is still up for debate.
Research shows that exercising for more than 1.5 hours without refueling your body or giving it enough time to recover suppresses your immune responses for up to a few days. During that time, your cortisol levels rise, your white blood cell count drops and youâre more likely to develop a respiratory infection.
This problem usually affects elite athletes, such as marathon runners, most.
On the flip side, staying sedentary also increases your risk of infection, inflammation and chronic disease.
Q: Can exercise make an illness worse?
A:Â Yes, it can. This is a complex issue, but I like to tell my patients to do a âneck check.â If your symptoms are mostly of a mild cold without fever or lower respiratory symptoms, such as a productive cough, wheezing or shortness of breath, mild exercise can actually reduce congestion and may make you feel better.
If your symptoms are primarily in your lungs or you have a significant fever its better to rest until things settle down. Regardless, good hydration is important.
We all want to protect our kids whether it be from falls, bumps and bruises â or avoidable infections and diseases. To help your child avoid illness, itâs important to encourage good habits and take steps to boost their immune system from an early age.
âMost of what makes a childâs immune system strong is common sense,â says pediatrician Adriane Lioudis, MD. If you keep these five tips in mind, youâll stack the deck in your childâs favor for a healthier life.
1. For newborns, consider breastfeeding
While itâs a very personal decision (that isnât always possible), if you are able to exclusively breastfeed your child for at least six months, it may have benefits. Some research shows that breastfeeding your child might possibly reduce allergies, Dr. Lioudis says.
2. Promote regular hand washing
Eighty percent of infections are spread by touch. Teach your little one to take the time to wash their hands after sneezing, coughing and going to the bathroom. Washing hands with warm water and soap for at least 20 seconds can remove bacteria and viruses and can reduce the chance of lung infections by up to 45%.
âGet the flu shot for your child yearly, as well,â Dr. Lioudis says. This is particularly important for children with asthma and other chronic health conditions.
Also, if your family will be traveling internationally, itâs important to seek advice from your childâs healthcare provider about any needed vaccinations.
4. Make sleep a priority
To maximize immunity, children must get enough sleep.
Babies between 0 and 3 months need 14 to 17 hours of sleep. Those between 4 and 12 months need 12 to 16 hours of sleep.
Children between the ages of 1 and 2 need between 11 and 14 hours.
Kids between the ages of 3 and 5 should get from10 to 13 hours.
Children ages 6 to 12 should get between 9 and 12 hours.
Teens between the ages of 13 to 18 need 8 to 10 hours.
Not getting enough sleep limits the bodyâs ability to produce proteins called cytokines that help fight infection and reduce inflammation.
5. Encourage a healthy diet
A healthy diet is also important for your childâs immune system.
Dr. Lioudis recommends encouraging your child to âeat the rainbowâ when it comes to fruits and vegetables. A good selection of whole grains should be part of their diet as well. Keep processed foods to a minimum. Proper food choices can help ensure that your child gets enough vitamins â such as vitamin A and E. These vitamins are needed to maintain good health and a strong immune system.
You canât avoid all illness, but some kids need extra protection
âEven if you follow these tips, your child might still get between seven and 11 colds each year,â says Dr. Lioudis. She adds that you can expect each one to last up to two weeks.
Also, keep in mind that some things billed as common âremediesâ arenât effective in boosting immunity. For example, thereâs no definitive proof that large amounts of vitamin C or echinacea help prevent colds or shorten them, she says.
However, if your child has a compromised immune system, work closely with your pediatrician to find ways to improve his or her immunity. Each child needs a personalized approach because their individual immune system varies, Dr. Lioudis says.
âThereâs generally a different protocol with immunocompromised children. There are some vaccines we have to add in on top of what most children have, but itâs something that we must determine on a case-by-case basis.

Inflammation is a natural process initiated by the immune system in response to illness, trauma, toxins, physical stress and chronic disease. While acute inflammation is protective and allows our bodies to heal, it can become harmful if it persists, leading to chronic inflammation. Chronic inflammation, in turn, can lead to conditions such as arthritis, heart disease, and diabetes.
Several foods can contribute to inflammation. These include highly processed foods, refined carbohydrates, or foods high in added sugars. Conversely, other foods can help calm the immune system, decreasing inflammation.
Letâs explore which foods help lower inflammation and how they can be incorporated into an anti-inflammatory diet.
Fruits and Vegetables:Â Colorful fruits and vegetables naturally contain various phytonutrients and bioactive compounds that help keep inflammation in check. These foods form the foundation of the anti-inflammatory diet and can be enjoyed in abundance. For an extra boost of protection, try drizzling antioxidant-rich olive oil on your veggies..
Protein:Â Choose primarily from plant-based sources such as legumes, soy, nuts, and seeds, with smaller amounts from lean cuts of animal protein and fatty fish. The fats in these proteins, mainly monounsaturated and omega-3, play a significant role in combating inflammation. The American Heart Association recommends 6 to 8 ounces of fatty fish and 5 ounces of legumes, nuts, and seeds per week.
Whole grains:Â Whole grains contain all parts of the grain, whereas refined grains remove the germ and bran, eliminating important inflammation-reducing compounds. Of these, fiber is a bit of a superstar, shown to help reduce blood sugar and cholesterol levels. Aim for at least 50% of your grains from whole grain sources, such as rolled oats and brown rice.
Herbs and Spices: Herbs and spices add flavor to your food and help reduce oxidative stress, which can trigger inflammation. Add ginger, turmeric, clove, cinnamon, oregano, and garlic to your next meal.
What change can you make today to shift your body into a less inflamed state?
Consider adding one colorful fruit or vegetable to your diet each day. Suggestions include tomatoes, oranges, yellow bell peppers, arugula, blueberries, pumpkin and broccoli.

Yes, alcohol affects hormones in women by increasing estrogen and cortisol, and decreasing progesterone, which can lead to issues like irregular menstrual cycles, worsened menopause symptoms, and an increased risk for certain health conditions. The liver prioritizes metabolizing alcohol, disrupting the body’s normal hormone regulation, and its effects are seen across all stages of a woman’s life.
Specific hormonal effects
Estrogen: Alcohol can increase estrogen levels by increasing its production or decreasing its breakdown. This is a concern because elevated estrogen is linked to an increased risk of certain cancers, such as breast cancer.
Progesterone: Moderate to heavy drinking can lead to lower progesterone levels, which is particularly relevant for premenopausal women and can disrupt the menstrual cycle and affect fertility.
Cortisol: Alcohol consumption increases cortisol, the body’s primary stress hormone. Chronically high cortisol levels can negatively impact bone growth, digestion, reproduction, and immune function.
Other hormones: Alcohol can also affect other key hormones, such as Anti-mĂźllerian Hormone (AMH), gonadotropins (like FSH and LH), and thyroid hormones, which can impact fertility and other bodily functions.
Effects on reproductive function
Menstrual cycle: Alcohol can cause irregular periods and, in some cases, complete cessation of menses.
Menopause: For menopausal and postmenopausal women, alcohol can worsen symptoms like hot flashes and night sweats and may increase the risk of conditions like osteoporosis and heart disease.
Fertility: Studies show women who drink more than 7 alcoholic drinks per week while undergoing fertility treatment are less likely to achieve pregnancy.
Important considerations
Risk increases with consumption: The more alcohol a woman consumes, the greater the impact on her hormones and overall health.
Short-term vs. long-term: The liver’s priority is processing alcohol, which disrupts hormone regulation. For women who are heavy or long-term drinkers, the long-term effects on hormone levels and associated health risks can be significant.
Seek professional advice: It is important to discuss any concerns about alcohol, hormones, and reproductive health with a healthcare provider.
Check-in with your care team, and focus on low-impact exercises and walking for good gains
If youâre living with advanced prostate cancer, you might be wondering exactly how far you should push yourself when it comes to physical activity and exercise. Should you take it easy and hold back? Or should you try to maintain your exercise routine?
And if youâve had your prostate surgery or your prostate removed (prostatectomy) you may be concerned about any sort of limitations or restrictions on specific exercises to avoid further pain or injury.
Occupational therapist Maria Pickston, OTR/L, CLT, reminds us that each personâs medical history and cancer treatment is unique. So, before beginning any exercise program during recovery, itâs essential to obtain clearance from your oncologist or healthcare team.
Pickston shares some additional insight on how exercise can help with the process of recovery and why exercise is so important overall.
Importance of exercise for prostate health
Your prostate is part of your pelvic floor, an area densely populated with a group of muscles and connective tissues that support the functions of your bowel, bladder and reproductive organs. Your pelvic floor muscles also aid your abdominals (core muscles) and back muscles in providing structural stability to your spine.
When we talk about prostate health, weâre most often talking about modifiable risk factors, which are the things you can do to reduce the likelihood of developing prostate cancer. But if youâre living with prostate cancer, focusing on your overall health is key and exercise is a big part of that.
âWhen you put the words âcancerâ and âexerciseâ together, it can feel like such a road block because it sounds counterintuitive to be exercising when youâre going through cancer treatment,â says Pickston.
âYears ago, people were told not to exert themselves and to take it easy. But in the last 20-plus years, weâve had an explosion of research supporting the benefits of physical activity for cancer survivors and how exercise can improve the symptoms and side effects of chemotherapy and radiation therapy.â
Exercise can have a huge impact on your physical, mental and emotional health and increase your energy levels â all things that tend to be affected when you have surgery or are going through cancer treatments.
âProstate cancer treatment can lead to several side effects like loss of muscle mass and physical strength, sexual dysfunction, reduced bone density, increased fatigue, and a higher risk of heart disease and diabetes,â explains Pickston.
Exercise plays a vital role in tackling these challenges and enhancing the physical outcomes of treatment.
âCurrent research demonstrates that exercise is safe and beneficial before, during and after cancer treatment as it improves energy levels and the overall quality of life, enabling individuals to continue enjoying the activities they love,â notes Pickston. âA physically active lifestyle not only helps in lowering the risk of various cancers, but also reduces the risk of recurrence in some cancers, including prostate cancer.â
Translation: Once you check in with your care team, donât let your cancer diagnosis stop you from working out.
How often should you exercise to promote prostate health?
If youâre living with prostate cancer, are going through cancer treatment or have had a prostatectomy, you want to talk to your healthcare provider first to before you begin any exercise program as you may need to adhere to certain precautions during those first few weeks of recovery.
Thereâs no one set exercise that specifically focuses on prostate health â but if you focus on improving your overall health, increasing your heart rate, improving your blood flow and getting those endorphins going, youâll find that those things will have significant positive impact on how youâre feeling overall and your ability to recover from your condition and treatment.
âIndividuals who are physically fit or active before their cancer diagnosis are more likely to regain their previous level of functioning compared to those who lead a more sedentary lifestyle,â says Pickston.
âIn oncology rehabilitation, personalized programs are designed to cater to each individualâs unique circumstances. Special considerations are taken into account, including your medical history, current fitness level, the type and stage of your cancer, and the specific cancer treatment you are having to ensure that the rehab process is both safe and effective.â
Everyone responds to cancer and cancer treatments differently. What works for someone else might not come as easily for you â and thatâs OK.
âEach individualâs journey is different, and your focus should be on finding an approach that suits your specific needs and abilities, fostering progress and overall well-being,â encourages Pickston.
And donât feel like you have to push yourself too hard â you can, and should, rest when you need it the most. Exercise doesnât always have to be a one-hour routine, either. It can be as simple as standing up and stretching during commercial breaks, walking to the end of your driveway and back, or making sure you keep up with your daily living activities around the house like laundry, cleaning and showering.
âJust the act of walking or going up and down the stairs is something you can immediately do when you get home after prostate surgery,â says Pickston. âBe patient with yourself and avoid pushing to the point of pain or excessive discomfort or fatigue. If itâs been a while since youâve been active or your overall fitness level is low, start slowly and gradually build. The key is to be as physically active as your current condition and abilities allow.â
Aerobic exercise for prostate and sexual health
Specifically, aerobic exercise (also known as cardiovascular exercise) has wide-ranging full-body benefits that can impact your heart, brain, joints, skin and muscles. It not only extends your life expectancy, but it can also decrease your blood pressure and heart rate, and increase your blood flow, which has a direct impact on your sexual function, mood, digestion and more.
Again, if you canât hit the ground running that fast, you can do small things to work your way back up to that routine.
âThink about all the physical activity you can do like playing with your grandkids, dancing, gardening, carrying groceries or doing chores around the house. But itâs even better if you begin to incorporate intentional exercises like brisk walking, swimming and weightlifting,â says Pickston.
âItâs crucial for those undergoing treatment to understand that exercise is the best way to treat cancer-related fatigue. As your strength and fitness improves, you can engage in meaningful activities more easily.â
One specific side effect mentioned earlier is loss of bone density, which can lead to osteoporosis, a condition where the bones become weak, less dense and more likely to increase your risk of fractures. Weight bearing exercises such as weight training, yoga, Pilates and climbing stairs are ideal for preventing bone density loss.
âStarting slowly with light weights and gradually increasing the load is key to avoid pushing too hard and experiencing pain or exhaustion,â advises Pickston. âWith time and consistency, you will notice improvements in your fatigue, strength and overall health, fitness and endurance.â
Caution for cycling as exercise
Cycling is an excellent aerobic exercise, but itâs one you might want to hold off from doing at least in the early weeks after having prostate surgery. The reason is because you tend to put a lot of pressure on your sit bones and your pelvic area while cycling, and this can cause discomfort, pain and swelling if youâre not fully healed.
âYou need to be sure you are cleared by your physician before initiating cycling for any amount of time first,â says Pickston. âOnce you receive clearance, there are various bike seats and bike shorts available to help cushion or accommodate the perineal area, alleviating some of that pressure.â
Kegel exercises
After having prostate surgery, itâs common to experience side effects like urinary leakage and erectile dysfunction. Kegel exercises specifically are designed to help strengthen your pelvic floor muscles and reduce the likelihood of those side effects from happening as well as help quicken recovery from those side effects. These exercises are also often recommended for some people before even having surgery so their pelvic floor muscles start off having a strong foundation before going into surgery.
âYour pelvic floor is often compromised after prostate cancer treatment because surgical or radiation treatment can damage the surrounding tissues, including the muscles of the pelvic floor,â explains Pickston. âWhen the pelvic floor muscles are compromised, it can lead to weakness, pain and dysfunction. Seeking help from a pelvic floor physical therapist can address these issues.â
Itâs also common to experience muscle tightness in your pelvic floor and surrounding muscles after treatment, and doing Kegels without proper guidance can worsen this tightness.
âA pelvic floor therapist will help to make sure you are performing your Kegels correctly and help guide you in managing areas of muscle tightness in your pelvic floor,â says Pickston. âLearning how to engage the pelvic floor muscles correctly during daily activities can significantly reduce leakage. Sometimes, just a few simple adjustments in movement can lead to dramatic improvement.â
Healthy weight and prostate health
Having overweight or obesity increases your risk for prostate cancer â but it can also provide additional complications during the recovery process in some cases.
âIf youâve had a prostatectomy, itâs normal to experience emotional ups and downs, but the important thing is that you focus on what small things you can do each day, to feel better every day,â says Pickston. âPhysical activity improves both your physical and emotional health. Itâs important for managing weight, maintaining or building muscle, reducing your risk of heart disease and keeping your bones strong.â
âYou want to get up, go outside and see whatâs going on in your neighborhood,â encourages Pickston. âWhen you start exercising, your sleep improves. When your sleep improves, youâre able to heal better. And the more you can do early on, the more long-term effects youâll experience along the way.â
Heavy alcohol consumption may lead to earlier and more severe brain bleeds, according to a study published by researchers at Massachusetts General Brigham earlier this month.
Using data from patients admitted to MGB between 2003 and 2019 who had brain bleeds, the researchers found that people who drank heavily â defined as three or more alcoholic drinks a day â were 11 years younger, on average, when their bleeds occurred.
Strokes can be categorized into two types: ischemic strokes, which occur when blood flow to the brain is blocked, and hemorrhagic strokes, which result from a ruptured blood vessel. The researchers focused on the latter, which typically lead to more severe damage.
âHemhorrhagic strokes, or brain bleeds, are less common, but they are a lot more dangerous,â said Edip Gurol, an associate professor of neurology at Harvard Medical School and author of the study. â50 percent of people who have a brain bleed die within the first month.â
The study, published in Neurology, tracked 1,600 patients over the course of 16 years, of which seven percent reported heavy alcohol consumption. The median age of brain bleeds for heavy drinkers was 64, compared to 75 in those who did not report heavy alcohol consumption.
âThere was a very, very significant difference, which is telling us that one way or the other, heavy drinking is accelerating the brain bleeds,â Gurol said.
Using CT scans to determine the size and location of bleeds, the authors found that heavy drinkers experienced 70 percent larger bleeds and were twice as likely to have a bleed deep inside their brain.
âThe brain bleeds in those patients were more likely to be deep and more likely to open inside the spinal fluid-filled spaces, the ventricles of the brain,â Gurol said.
Patients who reported heavy alcohol usage had higher blood pressure and lower blood platelet counts when they were admitted to the hospital, the study found. Those patients also showed greater evidence of small vessel damage in the brain, which is linked to several other health conditions such as dementia and heart failure.
âDespite their younger age, very probably because of the excessive alcohol use, these people had more severe small vessel disease-related brain damage, which is called white matter disease,â Gurol said.
Alvin S. Das, an assistant professor at Beth Israel Deaconess Medical Center, said the finding that heavy drinkers experienced larger brain bleeds would prompt him to stress the importance of cutting back on alcohol to his patients.
âWhat it might compel me to do is in a patient that comes to my office and theyâve had a deep hemorrhage, not only counsel them on aggressive hypertension management down the road to prevent another hemorrhage, but this study also would push me to counsel alcohol cessation,â Das said.
Because the number of heavy drinkers in the study was small and the data came from a single hospital, the researchers noted that future work should use larger datasets to examine how varying levels of alcohol use affect brain aging and stroke risk.
Gurol, for his part, said the findings underscore the importance of limiting alcohol consumption broadly, even in individuals without pre-existing health conditions.
âEven for people without known risk of alcohol damage, it is probably best to not to exceed three glasses per week and not to exceed one glass in over 24 hours,â Gurol said.

Avocados are jam-packed with nutrients and vitamins and can make a delicious, nutritious addition to your diet.
Millenials may get flak for being the âavocado toast generation,â but honestly, they may be onto something! Avocados are as nutritious as they are delicious, and theyâre jam-packed with vitamins and nutrients.
Avocados include vitamins C, E, K1, B6 and folate, plus essential minerals like potassium and copper. Theyâre low in sugar, loaded with fiber and high in monosaturated fats, aka âgoodâ fats. Oh, and did we mention that they taste great and theyâre super versatile?!
Registered dietitian Julia Zumpano, RD, LD, shares a few more good reasons to give these wrinkly green fruits a second look â plus, how to add them to your regular rotation.
Are avocados good for you?
âAvocados are a great addition to a healthy diet,â Zumpano confirms, âand there are hundreds of varieties to choose from, ranging from big to small and wrinkly to smooth.â
What they have in common: A big round pit, creamy green flesh and a whole lot of nutrients crammed into a handy, pear-shaped package.
Just donât go overboard. Avocados are packed with nutrients, but theyâre also packed with calories. A 50-gram portion â about a third of a medium-sized avocado â has about 75 calories. And an entire large avocado can add upward of 400 calories to your daily diet.
Like most things, Zumpano says, moderation is key. âAs long as youâre paying attention to portion sizes, avocados are very healthy foods to include in your food repertoire.â
Benefits of avocados
Whether youâre adding a slice to a salad or sandwich or using them as an ingredient in a more complicated recipe, Zumpano says avocados have a lot going for them health-wise.
Here are some of the many nutrients and vitamins packed into just a single avocado:
High in âgoodâ fats
You mightâve heard that avocados are high in fat â and thatâs true, but it doesnât mean you should avoid them! A medium avocado has 22 grams of fat, which includes 15 grams of monounsaturated fats, aka âgoodâ fats.
âAvocados are rich in heart-healthy monounsaturated fats, which help lower your LDL, or âbadâ cholesterol,â Zumpano says. âLow LDL levels reduce your risk of heart disease and stroke.â
The American Heart Association says most of the fats you eat should be monounsaturated or polyunsaturated, confirming that avocados fit the bill as part of a healthy diet.
You can even swap avocado in for less-healthy fats in your home cooking. Here are some additional ways you can add this smooth, creamy fruit to your diet.
Spread avocado on a sandwich in place of mayonnaise.
Instead of dunking veggies into dips made with cheese or sour cream, try guacamole.
Forego shredded cheese on your salad and add avocado slices instead.
In baking recipes, replace butter or oil with mashed avocado, like in these chocolatey avocado brownie bites.
âIf you use avocado to replace other fats, you can enjoy the flavor and nutrients and also cut down on saturated fats,â Zumpano says.
Lots of vitamins
Letâs talk vitamins: In simple terms, avocados have a lot of them! Here are the vitamins that are most abundant in avocados and what they do for your health:
Vitamin K1, or phylloquinone, is important for blood clotting, which helps stop wounds from bleeding. It also plays a role in strengthening your bones. For most adults, the daily recommended amount of vitamin K ranges from 90 to120 micrograms. Half an avocado has about 21 mcg.
Vitamin C, aka ascorbic acid, helps keep your immune system healthy. It also plays a role in the health of your tissues, blood vessels, bones and more. Depending on your age and sex, you need anywhere from 75 to 120 milligrams of vitamin C per day; half an avocado has about 10 mg.
Vitamin E, or alpha-tocopherol, is a powerful antioxidant that prevents cell damage and helps maintain muscle function. Most adults only need 15 mg of vitamin C per day, and half an avocado will give you about 4 mg of it.
Vitamin B6, also known as pyridoxine, helps your body convert food into energy. You only need a small amount of vitamin B6 each day (just 1.2 to 2 mg, depending on your age and sex), but half an avocado has about .25 mg, putting you well on your way to that daily goal.
Folateis a B vitamin thatâs important for normal cell function and tissue growth. It helps your body form red blood cells and DNA, which is especially critical when youâre pregnant (but still important if youâre not). Half an avocado has about 20% of your daily recommended amount.
Low in sugar
Though most fruits are high in natural sugars, avocados rank very low on the sweetness scale. âA whole avocado has under 1.5 grams of sugar, while one medium apple, by comparison, has about 19 grams,â Zumpano points out. (Psst: Itâs important to note that not all sugars are created equal! Fruit is still super-healthy.)
High in fiber
Avocados are a good source of fiber, which is a type of carbohydrate that your body canât break down. You need both soluble and insoluble fiber â and lucky for you, avocados have both.
âFiber can lower cholesterol and blood sugar, keep you regular and help you feel full and satisfied after a meal,â Zumpano states. Most adults need 25 to 35 grams of fiber per day, depending on your age and sex. Half an avocado provides about 7 grams.
Packed with potassium
Surprise! âAvocados actually contain more potassium than bananas,â Zumpano reveals. Half a large avocado provides about 485 mg of potassium, while a whole banana provides about 420 mg. (Most adults need 2,600 to 3,400 mg per day.)
This essential mineral is beneficial for blood pressure control and heart health. Low blood potassium can increase your blood pressure, raise your risk of kidney stones and even pull calcium out of your bones.
Increases your copper intake
Think past pennies: Copper is actually an essential trace mineral that your body needs in order to function correctly. Most Americans donât get enough of it in their diets, but half an avocado will get you 20% of your daily recommended amount.
âCopper helps your body metabolize iron, and it plays a role in a healthy immune system and nervous system,â Zumpano explains.
Tips for enjoying avocados
âA perfectly ripe avocado is slightly firm but not rock-hard,â Zumpano says. âIf itâs not ripe but you canât wait to eat it, store it in a paper bag on the counter until it gives a little when you squeeze it.â
A ripe-but-not-too-ripe avocado is a time-limited treasure, so dive right in and get creative with your avocado creations, or embrace the millennial method and enjoy some avocado toast.
But if you need to store it for a couple of days, just be sure to keep it in the fridge â not submerged in water, as some TikTokkers recommend. Some people call it a âfood hack,â but it can easily lead to foodborne illness.
âYou can even freeze avocado slices if youâre worried you wonât use them in time,â Zumpano suggests. âThen, you can easily throw them into a smoothie.â

Acupuncture has been used to treat many pain conditions, including low back pain, shingles and other nerve pain, hand and knee pain, headaches, fibromyalgia, and menstrual pain.
How acupuncture works
According to traditional Chinese beliefs, acupuncture works by affecting the flow of energy (called qi) through 12 channels, or meridians, that run lengthwise through the body.
Acupuncture involves the insertion of extremely fine needles into the skin at specific âacupointsâ along the meridians. This action, some scientific evidence has shown, may result in pain relief by releasing endorphins, the bodyâs natural painkilling chemicals, and may affect the part of the brain that governs levels of serotonin, a neurotransmitter involved with mood.
A related technique called acupressure does not involve the insertion of needles at all, but substitutes deep pressure, usually with a finger or thumb, at acupressure points.
How is acupuncture administered?
Acupuncture technique can vary with the practitioner:
During Chinese acupuncture, the acupuncturist may turn or twirl the needles slightly, or apply heat or electrical stimulation to enhance the effects. In some cases, an herb called mugwort is burned near the needle tips or over specific areas of the body to stimulate the acupoints; this is called moxibustion.
While traditional moxibustion may involve placing mugwort directly on the needle or skin, more commonly in the U.S. indirect methods are used, where the mugwort is burned near the skin without making contact.
A Japanese form of acupuncture involves more shallow needle insertion than Chinese acupuncture, and needles usually are not manipulated.
Korean acupuncture focuses on needling points just in the hands and feet.
Generally, the acupuncturist will start by asking you about your pain and other symptoms and your medical and family history. They may also do a physical exam, take your pulse, and press on various parts of your body to identify swelling or sensitivity.
Acupuncturists use a holistic approach. Therefore, the treatment will likely address general whole-body imbalances as well as your specific complaint. The acupuncturist typically inserts four to 10 needles and leaves them in place for 10 to 30 minutes while you rest. A usual course of treatment includes six to 12 sessions over a three-month period.
Minor side effects can include pain, bruising, or bleeding at the site of the needle insertion. The complication rate for acupuncture appears to be quite low. Skin infections have also been reported. Single-use, sealed needle packages have all but eliminated the risk of blood-borne infection such as hepatitis B or HIV.
A study published in The Journal of Pain pooled results of 39 studies involving nearly 21,000 people who received either acupuncture, simulated acupuncture, or no acupuncture for osteoarthritis, headaches, or chronic pain in the back, neck, or shoulders. True acupuncture provided the greatest pain relief, and the benefits persisted for at least a year. A 2021 study in Advances in Therapy found that acupuncture can help with low back pain up to two years after treatment.
If you decide to try acupuncture, it is crucial to seek out an experienced acupuncturist. Licensing requirements vary from state to state. In states with no licensing requirements, the safest way to find a qualified acupuncturist is to seek one with certification from the National Certification Commission for Acupuncture and Oriental Medicine. Some physicians also practice acupuncture, so ask your doctor for a referral. Increasingly, insurers cover acupuncture for conditions such as low back pain.
Even casual drinking can put your long-term health at risk. Our liver specialist explains the findings of this study.
New Study: No Level of Alcohol â Even Casual Drinking â Is Entirely Safe
Leading cause of death of those age 15-49
Stopping for happy hour with colleagues after work. Cracking open a cold beer (or two) while watching the game. Meeting up with girlfriends for a glass of pinot noir. Having an alcoholic beverage of choice is a common way to unwind. But according to a recent study, even casual drinking can put your long-term health at risk.
Liver specialist Jamile Wakim-Fleming, MD, did not take part in the study, but says the research found that alcohol was a leading risk factor for both disease and premature death.
âThey found that alcohol was the seventh leading cause of death worldwide,â she says. âBut even more alarming, is that it was the first leading cause of death of people between the ages of 15-49.â
What the study examined
The study looked at global data from hundreds of previous studies and found that for all ages, alcohol was associated with 2.8 million deaths each year.
Researchers found that alcohol-related cancer and heart disease, infectious diseases, intentional injury, traffic accidents and accidental injury were some of the leading causes of alcohol-related deaths.
But isnât alcohol good for your heart?
Dr. Wakim-Fleming says people often believe that a little bit of alcohol, wine in particular, may be good for their heart. But the study results didnât show any health benefit to drinking any amount of alcohol.
She says this information, along with previous research that has shown more young people are dying from alcohol-related liver disease, indicates that excessive drinking among young adults is a growing problem.
The damage grows over time
And like any substance-abuse problem, Dr. Wakim-Fleming says the damage to the body from alcohol increases over your lifespan.
âItâs a cumulative effect,â she explains. âIf you do it all at once, then youâre going to have the effect now. If you drink on a regular basis, over years itâs going to be cumulative and you will end up with a problem later on.â
Dr. Wakim-Fleming notes that anything we do in life involves risk, but itâs important to know what the risks are so that we can make the best decisions for our health.
