Sauna Safety
Sauna use is safe for the vast majority of healthy adults. The following guidelines ensure a safe and enjoyable experience.
Before Your Session
Hydration: Drink 1–2 glasses of water before entering the sauna. Sauna use causes significant sweating — dehydration is the most common cause of discomfort.
Avoid alcohol: Do not use a sauna after consuming alcohol. Alcohol impairs the body's ability to regulate temperature and significantly increases the risk of dehydration and cardiovascular stress.
Avoid heavy meals: Wait at least 1–2 hours after a heavy meal before using the sauna.
Medical conditions: If you have a cardiovascular condition, uncontrolled hypertension, or any other serious medical condition, consult your doctor before using a sauna.
During Your Session
Session duration: 10–20 minutes per session is recommended. Beginners should start with 5–10 minutes.
Temperature: Start on the lower bench if you are new to sauna use. Move to the upper bench as you become accustomed to the heat.
Listen to your body: Exit the sauna immediately if you feel dizzy, nauseous, faint, or experience chest pain or palpitations.
Children: Children under 3 should not use a sauna. Children aged 3–12 should use the lower bench for no more than 5–10 minutes, always supervised by an adult.
After Your Session
Cool down gradually: Do not immediately plunge into very cold water after your first sauna session. Allow your body to cool gradually.
Rehydrate: Drink water or an electrolyte drink after your session.
Rest: Allow 10–15 minutes of rest between sauna sessions.
Who Should Seek Medical Advice
