Sauna Before or After Workout: Pros, Cons, and Best Practices

Navigating the world of wellness can often feel like walking through a maze, especially when it comes to optimizing your fitness routine. One frequently debated topic is the timing of sauna sessions in relation to exercise. Should you hit the sauna before or after workout sessions?

This article delves into the benefits, drawbacks, and science behind each approach, helping you make an informed decision tailored to your individual needs and goals.

The Benefits of Sauna Use


Saunas are not just a luxury or a way to relax; they offer genuine health benefits that have been studied extensively. Here’s a more in-depth look at the advantages of incorporating sauna sessions into your routine:

1. Detoxification

Saunas, especially traditional ones that operate at high temperatures, encourage sweating. Sweating is one of the body’s most natural ways to eliminate toxins. This process can help flush out substances like heavy metals and chemicals, contributing to a cleaner internal environment.

2. Improved Cardiovascular Function

The high temperatures in saunas cause blood vessels to expand, increasing blood flow and reducing blood pressure temporarily. This cardiovascular “workout” can improve heart health over time when used in conjunction with a balanced exercise regimen.

3. Stress Relief

The heat in saunas stimulates the release of endorphins, the body’s natural feel-good chemicals. Additionally, the heat helps to relax muscles and relieve tension, providing a sense of well-being and relaxation.

4. Improved Muscle Recovery

The increased blood flow from the sauna’s heat can help in the recovery of muscles after a strenuous workout. This is particularly useful for athletes or fitness enthusiasts looking to minimize downtime and maximize performance.

5. Immune System Boost

Regular sauna use has been shown to increase the production of white blood cells, enhancing the body’s ability to fight off infections and diseases.

Sauna Before a Workout


Using a sauna before a workout has its unique set of advantages and disadvantages. Whether you should opt for this timing depends on your specific goals, the type of exercise you’re planning to do, and your individual health considerations. Let’s dive deeper into the pros and cons.


1. Mental Preparation and Focus

The serene environment of a sauna can serve as a mental “preparation chamber,” allowing you time to focus on the workout ahead. It can help you set your intentions, visualize your performance, and mentally prepare for the challenge.

2. Improved Blood Flow

A sauna’s heat triggers vasodilation, or the widening of blood vessels, which leads to increased blood flow. This can serve as an effective warm-up and prepare your cardiovascular system for the physical exertion to come.

3. Endorphin Activation

The stress induced by the heat activates your endocrine system, releasing endorphins. These ‘feel-good’ hormones can make your upcoming workout more enjoyable and may even help you perform better.

4. Increased Flexibility

The heat helps to loosen up your muscles and improve your range of motion. This can be particularly beneficial if you’re planning on doing exercises that require a lot of flexibility or complex movements.


1. Potential Dehydration

One of the most significant risks of using a sauna before a workout is dehydration. Sweating in the sauna will cause you to lose fluids that are crucial for optimal performance during exercise. It’s essential to hydrate adequately both before and after the sauna to counter this.

2. Reduced Performance

Although the heat warms up your muscles, it can also lead to a relaxed state that might not be ideal for all types of exercises, especially those that require quick reflexes or explosive movements.

3. Muscle Fatigue

Spending too much time in the sauna before a workout could prematurely fatigue your muscles. This can negatively affect your strength and endurance levels, thereby reducing the quality of your subsequent workout.

4. Safety Concerns

Using a sauna before exercise could be risky for individuals with specific health issues like cardiovascular conditions, low blood pressure, or certain respiratory ailments. It’s crucial to consult a healthcare provider if you have any underlying health concerns.

Sauna After a Workout


Opting for a sauna session after your workout can offer distinct benefits, but like any health-related activity, it comes with its own set of caveats. Here’s a more detailed breakdown:


1. Muscle Recovery

The increased blood flow and heat can facilitate muscle recovery, helping to ease soreness and possibly even accelerate the healing of minor injuries. The heat induces an artificial fever-like state, which ramps up your body’s natural healing processes.

2. Relaxation and Stress Relief

A workout can be taxing both mentally and physically. A sauna session afterward can act as a cool-down phase, helping to relax tensed muscles and mind.

3. Detoxification

As you sweat, you’re not just losing water; you’re also expelling toxins. This post-workout detox can complement the body’s natural cleansing processes.

4. Enhanced Metabolism

The high temperature can stimulate your metabolism, offering a kind of “afterburn” effect that helps you burn more calories even after your workout has ended.


1. Dehydration Risk

Just like using the sauna before a workout, there’s a risk of dehydration when you use it afterward. This is particularly concerning if you’ve already lost a lot of fluids during your exercise session.

2. Overexertion

Your body is already in a stressed state post-workout. Adding another physically demanding activity right after could potentially lead to overexertion, though this largely depends on the individual and the intensity of both the workout and sauna session.

3. Muscle Relaxation

While muscle relaxation is generally seen as a positive, it can also lead to a temporary decrease in muscle tone. If you’re looking to maintain muscle stiffness for any reason — perhaps you’re an athlete in training — this could be a concern.

4. Health Considerations

As always, if you have certain medical conditions, such as cardiovascular issues or respiratory concerns, it’s essential to consult a healthcare provider before incorporating sauna sessions after your workouts.

How Long Should You Be In the Sauna?

How Long

Deciding how long to spend in the sauna can be a bit challenging, especially for those new to the experience. Here’s how to gauge the appropriate amount of time:

Type of Sauna

Different saunas require different durations. Traditional Finnish saunas, which are hotter, typically demand shorter sessions — often around 15 minutes. Infrared saunas are generally less hot and therefore permit longer sessions, often up to 30 minutes.

Individual Tolerance

Everybody’s tolerance to heat varies. If you’re new to saunas, it’s advisable to start with shorter durations, perhaps around 5–10 minutes, and gradually build up as you get more accustomed to the heat.

Health Status

Certain health conditions may influence how long you should stay in a sauna. People with cardiovascular issues, for instance, should consult a healthcare provider for advice tailored to their condition.

Listen to Your Body

One of the most reliable indicators is your own comfort level. If you start feeling lightheaded, overly sweaty, or nauseous, it’s time to exit, regardless of how long you’ve been inside.

Incremental Increase

If you’re new to saunas or are trying to extend your time, do so in small increments. Adding an additional minute or two to each session can help your body adapt without overwhelming it.

By considering these factors, you can determine an optimal sauna session duration that is both safe and beneficial for you.

Sauna Before or After a Workout: Which One Is Best?


The question of timing — should you use the sauna before or after a workout — often confuses even seasoned fitness enthusiasts. However, the ideal timing largely depends on your specific goals, what you’re comfortable with, and any medical conditions you may have.

If Your Focus Is Mental Preparation and Warm-Up

If you find that warming up properly helps you get the most out of your workouts, you might consider using the sauna beforehand. The heat will increase your blood flow, warm your muscles, and help you mentally prepare for your workout session.

If Your Focus Is Recovery and Relaxation

If you’re looking to maximize recovery and reduce muscle soreness post-exercise, then using the sauna after your workout is likely your best bet. Your muscles will already be warmed up, reducing the risk of strain, and the heat will help accelerate the process of muscle recovery.

A Hybrid Approach

For those who can’t decide, there’s also the possibility of a hybrid approach — using the sauna both before and after workouts, but for shorter periods. This allows you to reap the benefits of mental preparation and improved circulation before your workout and muscle relaxation and detoxification afterward.

Personal Factors

It’s also essential to consider any health issues or individual characteristics that might make one option better for you than the other. For example, some people find that they are too relaxed after a sauna session, making a strenuous workout immediately afterward less appealing. Likewise, some might find that using the sauna beforehand makes them too dehydrated to perform well during their workout.

By weighing the pros and cons of each option, and perhaps through a bit of experimentation, you can determine which approach works best for you.

Safety Precautions


No matter how many benefits saunas offer, it’s crucial to approach them with a mindset geared toward safety. Here are some guidelines to follow:

1. Hydration

This is probably the most crucial safety tip. Due to the intense sweating in a sauna, you can easily become dehydrated. Make sure to drink plenty of water before entering, have a bottle of water with you during the session, and rehydrate generously afterward, especially if you’ve had a workout.

2. Time Limit

Most experts recommend a maximum of 15–20 minutes in a sauna per session. First-timers should start with even less to see how their bodies react. Never push yourself to stay longer than is comfortable.

3. Signs of Overheating

If you start to feel dizzy, nauseous, or otherwise unwell, it’s a sign that you should exit the sauna immediately. These could be symptoms of overheating or dehydration, which can be dangerous if ignored.

4. Preexisting Conditions

People with certain medical conditions, like heart problems, should consult a healthcare provider before using a sauna. Additionally, pregnant women and individuals taking certain medications should also seek medical advice.

5. Cool Down

After exiting the sauna, give your body time to adjust back to its normal temperature. A cool shower and a few minutes of rest are good practices to incorporate into your post-sauna routine.


Whether you opt for a sauna before or after your workout, understanding the pros and cons of each option can help you maximize the benefits. Safety precautions are essential, so consult a healthcare provider for personalized advice tailored to your needs.
