Yes, alcohol affects hormones in women by increasing estrogen and cortisol, and decreasing progesterone, Source: AI

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-müllerian 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.

The health of mothers and babies is the foundation of healthy families and communities, helping ensure hopeful futures for us all. @WHO

https://x.com/i/broadcasts/1ynKOlrpYWWGR

The health of mothers and babies is the foundation of healthy families and communities, helping ensure hopeful futures for us all.

World Health Day, celebrated on 7 April 2025, will kick off a year-long campaign on maternal and newborn health. The campaign, titled Healthy beginnings, hopeful futures, will urge governments and the health community to ramp up efforts to end preventable maternal and newborn deaths, and to prioritize women’s longer-term health and well-being.

WHO and partners will also share useful information to support healthy pregnancies and births, and better postnatal health.

Visit the World Health Day 2025 campaign page
 

Helping every woman and baby survive and thrive

This task is critical. Tragically, based on currently published estimates, close to 300 000 women lose their life due to pregnancy or childbirth each year, while over 2 million babies die in their first month of life and around 2 million more are stillborn. That’s roughly 1 preventable death every 7 seconds.

Based on current trends, a staggering 4 out of 5 countries are off track to meet targets for improving maternal survival by 2030. 1 in 3 will fail to meet targets for reducing newborn deaths.

Listening to women and supporting families

Women and families everywhere need high quality care that supports them physically and emotionally, before, during and after birth.

Health systems must evolve to manage the many health issues that impact maternal and newborn health. These not only include direct obstetric complications but also mental health conditions, noncommunicable diseases and family planning.

Additionally, women and families should be supported by laws and policies that safeguard their health and rights.

Campaign goals

  • To raise awareness about gaps in maternal and newborn survival and the need to prioritize women’s longer-term well-being.
  • To advocate for effective investments that improve the health of women and babies. 
  • To encourage collective action to support parents as well as health professionals who provide critical care.
  • To provide useful health information relating to pregnancy, childbirth, and the postnatal period.
     

Get involved

Here’s what you can do to support the campaign:

  • Spread awareness: share information about the campaign using #HopefulFutures and #HealthForAll.
  • Participate: attend our global events to learn more about what it will take to end maternal and newborn mortality.
  • Donate: contribute to the WHO Foundation which supports WHO’s work to protect mothers and babies in countries around the world.
  • Share your lived experiences: share your own experiences or stories of pregnancy and birth and thank those who provide quality care.

Colorful fruits and vegetables are packed with phytonutrients that help calm inflammation — a natural process that, when chronic, can contribute to heart disease, arthritis and diabetes. by Tamara Soerense @MayoClinic

Can eating the rainbow help to reduce inflammation?

11/6/2025 by Tamara Soerense

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.

Let’s explore which foods help lower inflammation and how they can be incorporated into an anti-inflammatory diet.

  • Fruits and Vegetables: 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: 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: 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.

Are your kids interested in sports or just want to feel stronger? @MayoClinic #physicalactivity

Are your kids interested in sports or just want to feel stronger? Strength training can be safe and beneficial for children when it is done the right way. Light weights, proper form and age appropriate guidance matter. Curious about when kids can start and how to keep it safe?

Strength training: OK for kids?

Strength training offers kids many benefits, but there are important warnings to keep in mind. Here’s what you need to know about youth strength training.By Mayo Clinic Staff

Strength training for kids? Great idea! Done right, it offers many benefits to young athletes. Strength training is good even for kids who just want to look and feel better. In fact, strength training might put your child on a lifetime path to better health and fitness.

Strength training, not weightlifting

Don’t confuse strength training with weightlifting, bodybuilding or powerlifting. Trying to build big muscles can put too much strain on young muscles, tendons and areas of cartilage that haven’t yet turned to bone, called growth plates. Also, being more focused on lifting large amounts of weight than on form can make strength training riskier.

For kids, light weights and controlled movements are best. Using good form and being safe are most important.

Children can do many strength training exercises using their own body weight or resistance tubing. Free weights, machine weights and medicine balls are other options. But keep in mind that some equipment designed for adults might be too large for many children.

What can kids get out of strength training?

Done right, strength training can:

  • Increase children’s muscle strength.
  • Help protect children’s muscles and joints from sports injuries.
  • Help children do better in nearly any sport.
  • Teach children proper form.

Keep in mind that strength training isn’t only for athletes. Even for children who don’t want to play sports, strength training can:

  • Strengthen bones.
  • Help promote healthy blood pressure and cholesterol levels.
  • Help maintain a healthy weight.
  • Help kids feel good about themselves.
  • Increase physical activity overall.

When can a child begin strength training?

During childhood, being active improves kids’ body awareness and control and their balance. Strength training can become a part of a fitness plan as early as age 7 or 8.

Younger children who start sports activities such as baseball or soccer also might benefit from strength training. To strength train, children should be able to follow directions and practice proper form.

The Department of Health and Human Services says that school-age children should get 60 minutes or more of daily activity. As part of this activity, muscle- and bone-strengthening exercises are suggested at least three days a week.

For children who have an interest in strength training, remind them that strength training is meant to increase muscle strength and endurance. Increasing muscle size, also called bulking up, is something else.

You might also check with your child’s healthcare professional for the OK to begin a strength training program. Be sure to check with your child’s healthcare professional if your child has a known or suspected health problem, such as a heart condition, high blood pressure or seizures.

What’s the best way to start a strength training program for kids?

A child’s strength training program isn’t just a scaled-down version of an adult program. Here are some things you can do to help your child train safely:

  • Talk with a professional. Start with a coach or personal trainer who has worked with youth to strength train. The coach or trainer can create a safe strength training program that works based on your child’s age, size, skills and sports interests. Or enroll your child in a strength training class for kids.
  • Keep watch. Don’t let your child strength train alone. It’s important to have an adult who knows how to strength train oversee your child’s program.
  • Keep it fun. Help your child vary the routine to prevent boredom.

Urge your child to:

  • Warm up and cool down. Your child should begin each strength training session with 5 to 10 minutes of light aerobic activity. This could be walking, jogging in place or jumping rope. This warms the muscles and prepares them for harder activity. Each strength training session should be followed with 10 to 15 minutes of light aerobic activity and gentle stretching. This helps keep blood flowing to the muscles during recovery.
  • Keep it light. Kids can safely lift light adult-size weights. Children can try to do one or two sets of 8 to 12 repetitions with good form. If they can’t do 10 repetitions, the weight might be too heavy.
  • Focus on good form. Form and technique are more important than the amount of weight your child lifts. Children can increase the resistance or number of repetitions little by little as they build strength.
  • Rest between workouts. Make sure your child rests at least one full day between exercising each major muscle group. Major muscle groups are the legs, hips, back, abdomen, chest, shoulders and arms.

Results won’t come overnight. But in time, your child will have more muscle strength and be able to work the muscles harder

Vitamin D is one of the most powerful nutrients for supporting the immune system @ClevelandClinic  🌞

Who doesn’t want a healthy immune system? (Raise your hand. No one?) But did you know the role your diet plays in keeping it in top shape to protect you from toxins and infections?
Sadly, too many of us don’t eat enough of the fresh fruits, vegetables and other foods we need to keep ourselves healthy year-round. Healthy foods provide many substances including vitamins and minerals to keep us strong and healthy. You can’t just eat an orange or grapefruit or pop a vitamin pill and expect one quick burst of vitamin C to prevent a cold and to boost your immune system.
“A truly healthy immune system depends on a balanced healthy diet over time,” says registered dietitian Maxine Smith. “It’s like training for a battle and preparing your body ahead of time so it can through a good punch when attacked by viruses, bacteria and toxins. Other lifestyle practices such as regular exercise and good sleep will better prepare you for the battle.” 
With some exceptions, it’s best to get your vitamins and minerals from your food rather than in pill form. Smith shares some tips for some of the top vitamins and minerals your immune system needs to perform:

1. Vitamin C
Vitamin C may help prevent infections or shorten their stay. Citrus fruits are a standout, but did you know there are other good sources? It’s true! Smith recommends the following:
Spinach.
Kale.
Bell peppers.
Brussels sprouts.
Strawberries.
Papaya. 
Fun fact: vitamin C is in so many foods that most people may not need to take supplements unless a doctor advises it. Consult with your doctor before taking any vitamin C supplements

2. Vitamin E
Like vitamin C, vitamin E can be a powerful antioxidant that helps your body fight off infection. This important vitamin — part of nearly 200 biochemical reactions in your body — is critical in how your immune system functions. To get your vitamin E, think high-fat plant foods such as:
Almonds.
Peanuts/peanut butter.
Sunflower seeds. 
Oils such as sunflower, safflower, and soybean oil.
Hazelnuts.

3. Vitamin A#

Vitamin A is an infection-fighter and comes in two forms: preformed such as in animal foods such as fish, meat and dairy or from plant carotenoids. Tuna is a great source of preformed vitamin A. When it comes to carotenoids, go colorful: 
Carrots.
Sweet potatoes.
Pumpkin.
Butternut squash.
Cantaloupe.
Dark green leafy vegetables.

4. Vitamin D
Known as the sunshine vitamin, it’s one of the most important and powerful nutrients for supporting the immune system. Food sources are limited but include:  
Salmon. 
Mackerel.
Tuna.
Sardines.
Vitamin D fortified like milk, orange juice and cereals. 
In general, it’s best to get most of your vitamins from food, but vitamin D may be the exception to that rule. Talk with your doctor to find out if you need a supplement. 

5. Folate/folic acid
Folate is the natural form and folic acid is the synthetic form, often added to foods because of its health benefits. To get more folate, add more beans and lentils to your plate on a regular basis, as well as leafy green vegetables. Avocado is another tasty source. You can also get folic acid in fortified foods (check the label first).
Enriched pasta.
Enriched bread.
Enriched rice.

6. Iron
Iron, which helps your body carry oxygen to cells, plays a part in many of the immune system processes. It comes in different forms. Your body can more easily absorb heme iron (aka iron from animal products), which is abundant in:
Red meat (limit to smaller amounts and less often).
Chicken.
Turkey.
Canned sardines.
Oysters.
Clams.
Mussels.
Canned light tuna.
If you’re a vegetarian, have no fear. You can still find iron in:
Beans.
Broccoli.
Kale.
Iron-fortified cereals.

7. Selenium
Selenium seems to have a powerful effect on the immune system being important for preventing infections. Animal foods are the best sources, with the exception of Brazil nuts, that offer a whopping greater than 100% daily value in one nut. However, too much can be a problem, so keep to no more than one to two of these in a day. Look for selenium in: 
Seafood (tuna, halibut, sardines).
Meat and liver.
Poultry.
Cottage cheese.

8. Zinc
Zinc is needed for the production of new immune system cells. It’s found primarily in animal foods but can be also found in some vegetarian food like.  
Oysters.
Crab.
Lean meats and poultry.
Baked beans.
Yogurt.
Chickpeas.
Choose frozen when you can’t get fresh
Depending on where you live and what time of year it is, you can’t always get your hands on high-quality fresh produce. Keep in mind that buying frozen is a good option and can be quite convenient in our time-crunched world. Frozen food can still boost your immune system. 
“Manufacturers freeze frozen fruits and veggies at ‘peak’ ripeness, which means they’ll pack a similar nutritional value as their fresh counterparts,” she says. “Just choose plain frozen foods rather than those with added sugars or sodium.”​

Make coffee part of your morning routine.@HarvardHealth

Coffee may help your skin stay healthy

By , Senior Faculty Editor, Harvard Health Publishing; Editorial Advisory Board Member, Harvard Health Publishing

Here’s a medical news story that combines a common habit (drinking coffee) with a common skin condition (rosacea) — and it even has a happy ending.

What is rosacea?

Rosacea is probably something you’ve seen plenty of times and didn’t know what it was — or perhaps you have it yourself. It’s that pink or red discoloration on the cheeks some people have, especially fair-haired women. Sometimes there are small bumps that may look a bit like acne. If you look closely (after asking nicely for permission, of course), you’ll see tiny blood vessels just under the surface of the skin. In more severe cases it may involve the chin, forehead, nose, ears, and other skin surfaces. It may affect the eyes, eyelids, and cause thickening of the skin over the nose.

We don’t know what causes rosacea. However, there are theories that it may be, at least in part, a genetic condition, as it can run in families. Because the immune system seems to be involved in the inflammation of rosacea, and because other autoimmune conditions (such as type 1 diabetes and multiple sclerosis) may accompany rosacea, abnormal immune function may play a role. Medications (such as topical anti-inflammatory drugs) and antibiotics can reduce redness and inflammation but there is no cure. Many people seem to be able to reduce signs of rosacea by modifying their diet to avoid foods that trigger it.

Rosacea affects more than 14 million people in the US, including some celebrities, such as Bill Clinton and the late Diana, Princess of Wales. And while it’s not dangerous, it can have a significant cosmetic impact. Caffeine, sun exposure, spicy foods, and hormonal factors are thought to be able to trigger rosacea’s development or make it worse once present. Yet, a new study challenges the connection between caffeine and rosacea.

More coffee, less rosacea?

A recent study analyzed health data from surveys provided to nearly 83,000 women over more than a decade and found that:

  • Those drinking four or more cups of coffee per day were significantly less likely to report a diagnosis of rosacea than those who drank little or no coffee.
  • Those drinking less than four cups of coffee each day were also less likely to have rosacea, though the protective effect was smaller.
  • Consumption of decaffeinated coffee was not linked to a lower incidence of rosacea.
  • Caffeine intake from other foods or beverages (such as chocolate or tea) had no impact on the likelihood of developing rosacea.

Why is this important?

These results of this study are more than just interesting observations. If other research can confirm the findings, it could lead to a better understanding of why rosacea develops in some people and not in others. Because inflammation driven by the immune system is thought to play an important role in rosacea, insights into the development of this disease could extend to advances in other autoimmune disorders. Finally, many people with rosacea (or a family history of the disease) who like coffee may avoid it because of the widespread notion that coffee will make it worse. The findings of this study suggest that’s not true.

There are always caveats

As with all research of this type, there are limitations to consider. For example, this study

  • only included women, most of whom were white — we’ll need additional studies of men and other ethnic groups to know if the findings extend widely.
  • relied on health surveys and study participants’ memories regarding past diagnoses and diet; such survey data may not always be accurate.
  • found a link between higher coffee consumption with lower risk of rosacea, but it cannot determine whether coffee consumption actually caused a reduction in rosacea.

The bottom line

Coffee is one of the mostly widely consumed beverages on the planet, and it’s also among the most widely studied. While it can cause problems for some people (such as heartburn, tremor, or palpitations), it’s a source of pleasure and enjoyment for millions. In addition, coffee has been linked with a number of health benefits, ranging from reductions in type 2 diabetes and liver cancer to greater longevity. From this latest research, it appears that you can add the possible prevention of rosacea to the list.

Biking is a good way to get your blood flowing..😍😃@ClevelandClinic #physicalactivity

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 — your internal defenses against infection — 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 won’t 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: 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: Fortunately, you don’t 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: 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: 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 you’re 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: Yes, it can. This is a complex issue, but I like to tell my patients to do a “neck check.” 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.

5 Ways to Boost Your Child’s Immune System for Life @ClevelandClinic Adriane Lioudis, MD.

We all want to protect our kids whether it be from falls, bumps and bruises — or avoidable infections and diseases. To help your child avoid illness, it’s important to encourage good habits and take steps to boost their immune system from an early age.

“Most of what makes a child’s immune system strong is common sense,” says pediatrician Adriane Lioudis, MD. If you keep these five tips in mind, you’ll stack the deck in your child’s favor for a healthier life.

1. For newborns, consider breastfeeding

While it’s a very personal decision (that isn’t 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%.

3. Don’t skip immunizations

Follow your pediatrician’s advice when it comes to the childhood vaccination schedule. Immunizations start in infancy and continue to adulthood and prevent measles, mumps, chickenpox, rotavirus and other infections.

“Get the flu shot for your child yearly, as well,” Dr. Lioudis says. This is particularly important for children with asthma and other chronic health conditions.

Also, if your family will be traveling internationally, it’s important to seek advice from your child’s healthcare provider about any needed vaccinations.

4. Make sleep a priority

To maximize immunity, children must get enough sleep.

Sleep requirements for each night vary by age:

  • 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 body’s 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 child’s immune system.

Dr. Lioudis recommends encouraging your child to “eat the rainbow” 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 — such as vitamin A and E. These vitamins are needed to maintain good health and a strong immune system.

You can’t avoid all illness, but some kids need extra protection

“Even if you follow these tips, your child might still get between seven and 11 colds each year,” 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 “remedies” aren’t effective in boosting immunity. For example, there’s 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.

“There’s generally a different protocol with immunocompromised children. There are some vaccines we have to add in on top of what most children have, but it’s something that we must determine on a case-by-case basis.
