How to Use a Sauna at the Gym: Steps, Timing, and Etiquette

To use a sauna at the gym, first hydrate and shower, then enter with a towel, sit or lie on a bench, and stay for 10–20 minutes, leaving if you feel dizzy or uncomfortable. Afterward, cool down gradually and drink water. This routine maximizes recovery benefits while minimizing risks.

Using a sauna after a workout can accelerate muscle recovery, reduce soreness, and improve cardiovascular health. However, proper technique and etiquette are essential for a safe and pleasant experience. This guide covers everything from preparation to post-sauna care, including gym-specific considerations.

Preparing for Your Sauna Session

Before entering the sauna, hydrate well. Sweating causes significant fluid loss, so drink water before your session. A quick shower removes sweat, lotion, and dirt, which is both hygienic and helps keep the sauna clean. Remove metal jewelry, as it can become uncomfortably hot, and leave electronics outside, as high temperatures can damage them. Avoid alcohol before sauna use, as it increases dehydration risk and impairs judgment.

If you have any medical conditions, such as cardiovascular issues, or are pregnant, consult a healthcare provider before using a sauna. Do not use the sauna if you are already overheated, feverish, or acutely ill.

Step-by-Step Sauna Use at the Gym

1. Enter and get comfortable: Place a clean towel on the bench before sitting or lying down. This is a key etiquette rule and keeps the bench clean.
2. Start with a short session: If you're new, begin with 5–10 minutes. Experienced users can aim for 10–20 minutes, but always listen to your body.
3. Relax and breathe normally: Sit or lie still. Avoid aggressive stretching, as heat can make you feel more flexible than usual and increase injury risk.
4. Monitor how you feel: If you feel faint, dizzy, nauseated, or excessively hot, leave immediately.
5. Cool down gradually: After exiting, take a cool shower to lower your body temperature and rinse off sweat.
6. Rehydrate: Drink water after your session to replace lost fluids.

In a traditional sauna, you may pour water on the rocks to increase humidity, but only if the facility allows it. Infrared saunas operate differently and do not use water on rocks.

Timing and Temperature Guidelines

The ideal sauna session length is 10–20 minutes. Beginners should start with 5–10 minutes and gradually increase. Traditional saunas typically run at 150–190°F (65–90°C), while infrared saunas are cooler at 110–140°F (49–60°C). Infrared saunas heat the body directly and are often more comfortable for longer sessions.

Use the sauna after your workout, not before. Heat exposure before exercise can lower energy levels and cause fatigue. Post-workout sauna use helps relax muscles and reduce soreness.

Gym Sauna Etiquette

• Make a quick entrance: Open and close the door promptly to keep heat inside.
• Dress appropriately: Wear a towel or swimsuit as per gym policy. Nudity may be allowed in gender-specific saunas, but always check rules.
• Bring a towel: Sit on a towel to keep the bench clean and hygienic.
• Keep conversations quiet: Many people use the sauna to relax; respect the quiet atmosphere.
• Shower before entering: This is basic hygiene and helps keep the sauna clean.
• Don't pour water on rocks without permission: In traditional saunas, ask or check signage first.
• Limit your time: Be mindful of others waiting, especially during busy hours.

Health Benefits of Post-Workout Sauna Use

Using a sauna after exercise offers several science-backed benefits:

• Faster muscle recovery: Heat increases blood flow, delivering nutrients and oxygen to muscles and flushing metabolic waste.
• Reduced soreness: Sauna use can decrease delayed-onset muscle soreness (DOMS) and inflammation.
• Cardiovascular health: Regular sauna bathing is linked to lower blood pressure and reduced risk of heart disease.
• Stress relief: Heat activates the parasympathetic nervous system, promoting relaxation.
• Improved sleep: The post-sauna drop in body temperature can help you fall asleep faster.

For example, a study in the Journal of Athletic Training found that basketball players who used an infrared sauna for 20 minutes after resistance training had better next-day jump performance and less soreness than those who did passive recovery.

Safety Considerations and When to Avoid the Sauna

Sauna use is generally safe for healthy individuals, but certain conditions warrant caution. Avoid the sauna if you are pregnant, have uncontrolled high blood pressure, heart disease, or are prone to fainting. If you feel dizzy, nauseated, or develop a headache, leave immediately and cool down.

Stay hydrated before and after, but avoid drinking alcohol. Limit sessions to 20 minutes to prevent overheating. If you are new to sauna use, start with shorter sessions and gradually increase.

Choosing the Right Gym Sauna

Not all gym saunas are equal. Traditional saunas use dry heat and high temperatures, while infrared saunas use light to heat the body directly at lower temperatures. Infrared saunas may be more comfortable for beginners. When choosing a gym, consider the type of sauna, cleanliness, and crowding. A well-maintained sauna enhances your recovery routine.
