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 โ€” your internal defenses against infection โ€” 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 wonโ€™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 donโ€™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 youโ€™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 โ€œneck check.โ€ 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.

9 Ways Alcohol Affects Your Health @ClevelandClinic

What Does Alcohol Do to Your Body? 9 Ways Alcohol Affects Your Health

Alcohol affects your whole body, from your liver and immune system to your brain and mental health

You probably already know that excessive drinking can affect you in more ways than one.

There are the empty calories that can lead to weight gain. Thereโ€™s the potential for injury and regrettable choices. And donโ€™t forget about the hangovers of course.

Heavy drinking can also lead to a host of health concerns, like brain damage, heart disease, cirrhosis of the liver and even certain kinds of cancer.

And thatโ€™s on top of the toll that alcohol use can take on relationships, not to mention the potential for financial strain and legal troubles.

But even moderate alcohol use changes the way your body functions.

We talked with hepatologist Shreya Sengupta, MD, about how alcohol use affects your body and your emotional health.

โ€œSome people think of the effects of alcohol as only something to be worried about if youโ€™re living with alcohol use disorder, which was formerly called alcoholism,โ€ Dr. Sengupta says.

โ€œBut when you consider how alcohol is metabolized and used by your body, we can start to see that even moderate and social drinking affects our health to some degree.โ€

Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.

Liver

Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide.

But when you ingest too much alcohol for your liver to process in a timely manner, a buildup of toxic substances begins to take a toll on your liver.

If alcohol continues to accumulate in your system, it can destroy cells and, eventually, damage your organs.

โ€œWhen your liver is overwhelmed by oxidizing alcohol, it generates molecules that inhibit fat oxidation,โ€ Dr. Sengupta explains. โ€œThe fats build up. Over time, it can lead to a condition known as steatotic liver disease.โ€

Steatotic liver disease used to go by the name fatty liver disease.

Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day. Thatโ€™s about one shot glass worth.

With continued alcohol use, steatotic liver disease can lead to liver fibrosis. Eventually, you can develop permanent and irreversible scarring in your liver, which is called cirrhosis.

โ€œThe good news is that earlier stages of steatotic liver disease are usually completely reversible in about four to six weeks if you abstain from drinking alcohol,โ€ Dr. Sengupta assures.

Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol.

Metabolism

You probably are keenly aware of the so-called โ€œbeer belly.โ€ Thatโ€™s shorthand for a round midsection that some people associate with drinking too much beer.

In reality, thereโ€™s no evidence that drinking beer (or your alcoholic beverages of choice) actually contributes to belly fat.

But thereโ€™s plenty of research to back up the notion that alcohol does lead to weight gain in general. Even for people who arenโ€™t particularly heavy drinkers.

โ€œDrinking gives your body work to do that keeps it from going about its other processes,โ€ Dr. Sengupta notes. โ€œAlcohol distracts your system from its regularly scheduled duties, including things like metabolizing carbohydrates and fats.โ€

Once you take a drink, your body makes metabolizing alcohol a priority โ€” above processing anything else.

Thatโ€™s because your body already has processes in place that allow it to store excess proteins, carbohydrates and fats. But there isnโ€™t a storage tank for alcohol. So, your system prioritizes getting rid of alcohol before it can turn its attention to its other work.

That allows excess calories from the foods you eat to sit around, leading to weight gain.

Gut health

Your gut microbiome is a hotbed of bacteria that help keep your digestive system happy and healthy. The trillions of microbes in your colon and large and small intestines are critical to proper digestion. They also help fend off inflammation and support healthy metabolism.

When you drink too much alcohol, it can throw off the balance of good and bad bacteria in your gut.

โ€œAlcohol can kill the good bacteria that live in your gut, allowing bad bacteria to grow unchecked,โ€ Dr. Sengupta explains. โ€œThat can lead to problems with digestion, inflammation and even organ damage.โ€

Having a glass of wine with dinner or a beer at a party here and there isnโ€™t going to destroy your gut. But even low amounts of daily drinking and prolonged and heavy use of alcohol can lead to significant problems for your digestive system.

Heart health

Too much alcohol is bad for your heart. Alcohol can cause:

  • Increased heart rate.
  • Spikes in blood pressure.
  • Irregular heartbeats (arrhythmia).
  • A weakening in your heart (cardiomyopathy).

Warnings from the World Heart Federation go so far as to state that no amount of alcohol is safe for your ticker.

But wait, you may be thinking, what about those headlines that claim red wine is supposed to be good for my heart?

There are a few studies that associate red wine with improved heart health in lab tests. But no research proves that red wine causes any improvements in heart health in people.

โ€œThe reality is that alcohol causes more health troubles than it could ever help,โ€ Dr. Sengupta reinforces. โ€œAnd that goes for your heart, as well as the rest of your body.โ€

Pancreas

Your pancreas helps your body digest food and manage your blood sugar. Drinking alcohol changes how your pancreas works.

โ€œYour pancreas secretes fluids. Alcohol use can thicken those fluids, which can clog the ducts that those fluids flow out of,โ€ Dr. Sengupta explains.

Like a clog in a drain, those thickened fluids can jam up your ducts. That can lead to pancreatitis, which is inflammation of the pancreas.

Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe.

Cancer risk

The U.S. Centers for Disease Control and Prevention (CDC) has a clear warning regarding the connection between drinking and cancer: โ€œThe less alcohol you drink, the lower your risk for cancer.โ€

Why?

Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors.

Alcohol use has been shown to raise your risk for several kinds of cancer. That includes cancers of the:

  • Mouth.
  • Esophagus.
  • Throat.
  • Liver.
  • Breast.
  • Colon and rectum.

Immune system

If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who donโ€™t drink. Thatโ€™s because alcohol can weaken your immune system and make your body more susceptible to infection.

โ€œWe see lower levels of a specific kind of white blood cells called lymphocytes in people who drink heavily for long periods of time,โ€ Dr. Sengupta reports. โ€œThat can leave them more vulnerable to infectious diseases.โ€

Brain

The morning after a night of over-imbibing can cause some temporary effects on your brain. Things like trouble concentration, slow reflexes and sensitivity to bright lights and loud sounds are standard signs of a hangover, and evidence of alcoholโ€™s effects on your brain.

Long-term alcohol use can change your brainโ€™s wiring in much more significant ways. Ways that your standard hangover cures wonโ€™t even begin to touch.

โ€œExcessive alcohol consumption can cause nerve damage and irreversible forms of dementia,โ€ Dr. Sengupta warns.

Mental health

Alcohol is a depressant. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. Chronic misuse can also lead to paranoia and hallucinations.

Even drinking a little too much (binge drinking) on occasion can set off a chain reaction that affects your well-being. Lowered inhibitions can lead to poor choices with lasting repercussions โ€” like the end of a relationship, an accident or legal woes. Each of those consequences can cause turmoil that can negatively affect your long-term emotional health.

โ€œAlcohol tends to cause more problems than it solves for a lot of people,โ€ Dr. Sengupta emphasizes. โ€œIf drinking is affecting your health, your relationships, your work, your finances, itโ€™s time to make some serious changes.โ€

Alcoholics Anonymous is available almost everywhere and provides a place to openly and nonjudgmentally discuss alcohol issues with others who have alcohol use disorder.

“Downward dog is one of the most popular poses”. Dawn Lorring, PT, MPT @ClevelandClinic

Take a โ€˜Pawsโ€™ With Downward Dog

This transitional and restorative yoga pose provides a full-body stretch

Physical therapist Dawn Lorring, PT, MPT, walks through the steps of how to do downward dog correctly and shares its many benefits.

From beginnerโ€™s yoga to more advanced practices, downward dog is one of the most popular posesโ€ฆwith a few common misconceptions.

Rounding your back, placing your feet too far apart or putting too much weight into your wrists can all create a deeper stretch than intended โ€” which increases your risk of injury.

Physical therapist Dawn Lorring, PT, MPT, walks through the steps of how to do downward dog correctly and shares its many benefits.

What is downward dog?

Downward dog (also known as downward facing dog, facing dog pose or Adho Mukha Svanasana in Sanskrit) is a foundational yoga pose. Itโ€™s often used as a transition between movements, like sun salutations. Itโ€™s also a form of active resting, active stretching and strengthening. This allows you to check in with yourself and re-evaluate your intentions during your practice.

You do downward facing dog by putting your body into an inverted V-shape (or pyramid), as if there were a straight line that runs through the top of your head up your spine and out of your butt toward the ceiling.

How to properly do downward facing dog

Facing dog pose wonโ€™t usually be your first movement when doing yoga. Before trying it, itโ€™s best to loosen up your muscles and joints and find ways to work it into your overall yoga practice.

Once youโ€™re warmed up and ready to go, follow these steps:

  1. Start on all fours with your hands shoulder-width apart and your knees in line directly behind your hips.
  2. Spreading your fingers wide, press down into your hands and tuck your toes (almost like youโ€™re using them to grip the floor beneath you).
  3. As you exhale, bring your hips up and back, as if thereโ€™s a string pulling your butt toward the ceiling, so your body creates an inverted V-shape (or pyramid).
  4. Focus on straightening your back, not rounding it, so your head and neck are relaxed between your upper arms. It helps to focus on pressing through your arms to โ€œpushโ€ the ground away from you and keep your arms active.
  5. Engageย your core musclesย and pull your tummy in.
  6. Keep your legs straight and, if itโ€™s comfortable for you to do so, try to drop your heels down to the floor.
  7. Adjust your posture by shifting your weight between your hands and feet until you sink comfortably into the position.
  8. Hold this pose for 10 to 15 seconds at a time, making sure to breathe throughout.
  9. For a more relaxed stretch, bend your knees a little and readjust your posture as needed.
  10. When youโ€™re done, exhale and move into your next pose or slowly lower yourself to the floor to enterย childโ€™s pose.

โ€œDownward facing dog isnโ€™t about keeping your heels on the ground or holding it for long periods of time,โ€ clarifies Lorring. โ€œItโ€™s really about making sure youโ€™re going to a place thatโ€™s comfortable for you, so you can adjust your body as often as you need in this pose.โ€

Facing dog pose variations

If you have a hard time getting down on your hands and knees, try this wall variation:

  1. Face the wall and place both your hands out in front of you so your palms are flat and your fingers are stretched out.
  2. Keeping your head and back straight and your hands on the wall in front of you, slowly walk your legs backward.
  3. As you move, walk your hands down the wall so you hinge at your hips and look directly at the floor.
  4. Keeping your head and neck relaxed, hold this pose for 10 to 15 seconds before slowly returning to stand.
  5. If you feel stress or discomfort in your wrists, you can modify by rolling up a towel or the edge of your yoga mat and placing the roll under the heels of your hands. This will decrease some of that pressure.

For a more challenging stretch that deeply engages your hips and hamstrings:

  1. While in the downward facing dog position, lift one leg up and stretch it toward the ceiling.
  2. For a deeper stretch, bend your outstretched leg back and over your body, so your knee is facing away from you.
  3. Repeat this process with the other leg, holding the pose for as long as you feel comfortable on either side.

Downward dog benefits

Downward facing dog provides a full body stretch, while also strengthening and working your:

Adho Mukha Svanasana helps improve your flexibility and control, and provides you a moment of active rest. It also increases blood flow to your head and upper body when youโ€™re in the inverted V position. But because of this, you should talk to your yoga instructor, athletic trainer or healthcare provider before starting this position if you have:

โ€œFacing dog pose tries to improve flexibility but also builds the strength to control that flexibility,โ€ says Lorring. โ€œIf youโ€™re feeling excessive stress to a certain part of your body, then youโ€™re probably holding the pose for too long or youโ€™re trying to go into a range that youโ€™re not ready for. We can help you get there.โ€
