pros and cons of sauna after workout

TL:DR: A post workout trip to the sauna can improve your recovery and boost your overall health. However, it can also lead to cardiovascular complications and other temporary problems. Read on to learn the pros and cons of going to a sauna after your workout. 

Saunas are a great way to relax and unwind after a workout, but before you hunker down in the heat, know that this ancient practice has both pros and cons.

Using a sauna in moderation (just like an ice bath) can help improve recovery and heart health, beat stress, and even boost immunity. 

For certain individuals, however, the risks can outweigh the benefits. If you have severe heart disease, a compromised cardiovascular system, and/or especially sensitive skin, or if you are trying to conceive or are already pregnant, check with your doctor before you hit the hot box.

The Story of the Sauna

The use of saunas after exercise has been practiced for centuries. Originating in Finland over 2000 years ago, saunas were soon adopted in other Scandinavian countries where they were used for healing purposes and also as gathering places for heated discussions. 

Today, the sweaty ritual is a popular relaxation and wellness activity around the world. 

Sauna Safety

The pros of a sauna visit after exercising will likely outweigh the cons for most people, but before you head to the hothouse, it’s crucial to follow a couple of precautions. 

  • Stay hydrated. Drink at least eight ounces of water after your workout and before you step into the sauna.
  • Once you’re inside, aim for a ten to twenty-minute roast. Less than this, and you probably won’t reap any health benefits. Longer? You run the risk of overheating.  

The Pros of an After-workout Sauna

Saunas are associated with a wide range of health benefits. Among the pros of this workout wrap-up are improved recovery and potential boosts in immunity and cardiovascular health.

1. Improved Recovery

One of the primary benefits of using a sauna after a workout is improved recovery. A post-workout steam bath can increase the body’s core temperature, which causes the blood vessels to expand, allowing more blood to flow freely through the body. 

The increase in circulation helps flush out lactic acid and other metabolic waste, which can reduce soreness and improve recovery time. 

The sweat equity you put into your sauna soak comes with its own recovery bonus. The heat causes users to perspire, which helps to eliminate toxins and other impurities from the body.

2. A Boost in Heart Health

A recent study published in the Journal of Physiology found evidence to suggest that a 15-minute post-workout sauna sit has heart health benefits similar to a modest-intensity workout.

Another study links sauna bathing to reduced cardiovascular mortality and improvements in cardiovascular risk prediction.

Several studies show a correlation between frequent sauna use and lower blood pressure and a decreased risk of cardiovascular disease and stroke––benefits researchers attribute to improved blood vessel function and cholesterol levels, and less inflammation.

Study authors caution that it may be difficult to attribute improved heart health solely to sauna use. It may be that a lifestyle that allows for regular sauna sitting may deserve some of the credit.

3. Stress Reduction

A sauna’s relaxing atmosphere combined with its heat and humidity can help reduce stress and anxiety and allow the body to relax, leading to a better overall sense of well-being. 

Addressing your stress should not be an after-workout afterthought. Stress can be the source of several mental and physical health problems from headaches and fatigue to depression and diabetes. 

Feeling bad can lead to unhealthy behaviors that may make you feel better temporarily, but in the long run, end up compounding the problem. Instead of taming the tension with your favorite bad habit, sweat your stress out with a sauna soak.

4. Enhanced Immunity 

When it comes to fending off infectious organisms, white blood cells are the body’s frontline defense, and there’s evidence to suggest a pre-battle sweat-fest can beef up your germ-fighting army.

In a study published in the Journal of Physiology, researchers document an increase in the white blood cell counts of study participants who took sauna baths after exercising but observed no change in those who skipped the steam room.

5. Weight Loss

The heat of a post-workout sauna gives your heart rate a slight boost, which stimulates your metabolism, cranking up the number of calories you burn while you sweat.

Researchers have found that sauna-level temperatures (150 degrees or more) will increase metabolic rates by about 20 percent for sauna-takers while they steam, and the effects last for a couple of hours after they return to normal temperatures.

Keep in mind that any weight you lose in the sauna will be water weight, and this kind of weight loss is due to dehydration, which is not a wellness goal. Always replace your water loss by sipping before and after your sauna.

Sauna baths alone will likely not affect weight, but as part of a healthy nutrition and exercise program, they can serve as healthy relaxation stations along your weight loss journey.

Sauna Cons: Reasons You May Want to Skip the Steam

Though using a sauna after a workout is generally safe and beneficial, consider these potential risks.

1. Overheating

Spending too much time in a sauna can lead to overheating which can result in fatigue, dizziness, nausea, dehydration, or heat exhaustion. The intense heat can increase your heart rate and blood pressure, which can put a strain on your cardiovascular system.

Most at risk of the negative health outcomes associated with overheating are people with severe heart disease and/or those who need to avoid risks associated with low blood pressure.

Individuals who have not had enough time to cool down after exercise or who seek out the sauna without replenishing the liquid lost during a workout also heighten their chances of overheating.

During exercise, the body produces sweat to cool itself, but in a sauna, the sweat is not released from the body, and the sauna’s heat and humidity can accelerate fluid loss.

To prevent dehydration, drink plenty of water before and after a sauna session. Listen to your body and take breaks if needed. 

2. Cardiovascular Complications in Heart Patients

Sauna sitting is generally a heart-healthy practice, but according to Harvard Health, if your heart is already under stress, it’s best to avoid extreme heat.

High temperatures cause the heart to work harder, which can be good if you’re healthy, but not if you have high-risk heart disease, chest pain (angina), or hypertension. 

3. Skin Irritation

The hot air of a sauna can cause skin irritation, worsen existing dermatitis, and even cause burns or rashes among people with especially sensitive skin. Use a moisturizer after a sauna session to help prevent problems like cracking, flaking, and redness. 

The sweat you shed in a sauna can draw out toxins, but also clog pores. If you are prone to breakouts, try a beta-hydroxy exfoliant to prevent sebum build-up that can lead to acne. 

4. Temporary Sperm Count Slumps

Researchers who conducted a 2013 study on how sauna exposure affects human spermatogenesis found a sauna’s heat can reduce sperm production in otherwise healthy men. The lowered sperm counts were only detectable during three months when study participants made weekly steam room visits. 

Once the men stopped using a sauna, their sperm counts returned to pre-study levels. Doctors recommend men avoid saunas if they are trying to conceive.
