Sauna Safety Guidelines

Saunas are safe for most healthy adults when you follow a few simple rules: hydrate, limit your time, listen to your body, and skip the sauna if you have certain health conditions or have been drinking. This guide brings together the practical safety steps for infrared and traditional saunas so you can enjoy the heat with confidence.

Sauna safety at a glance

Healthy adults can use a sauna safely by keeping sessions to about 15 to 20 minutes, drinking water before and after, and starting at a lower temperature while they adjust. Beginners should begin with 5 to 10 minute sessions around 130 degrees Fahrenheit and build up slowly. Never use a sauna after drinking alcohol or taking medication that affects how your body handles heat. Step out right away if you feel dizzy, nauseous, or lightheaded. People who are pregnant or who have heart disease, low or high blood pressure, or other chronic conditions should talk with a clinician before regular use. Cool down gradually afterward and replace fluids. These habits keep heat therapy comfortable and lower the risk of dehydration or overheating.

How long should a sauna session last?

For most people, 15 to 20 minutes is the upper limit for a single session. Beginners should start with 5 to 10 minutes and add a few minutes as they grow comfortable. Going much longer raises the risk of dehydration and overheating without adding benefit.

If you want a longer total experience, take a break to cool down and rehydrate, then return for a second short round rather than staying in for one long stretch.

What temperature is safe?

A comfortable range for traditional saunas is roughly 150 to 175 degrees Fahrenheit, while infrared saunas run cooler, often 120 to 140 degrees, because the heat reaches your body directly. Higher is not better. Start at the lower end, especially as a beginner, and raise the temperature only as it feels comfortable.

If you are new to heat therapy, an infrared cabin is a gentle place to start. You can compare options across our infrared saunas and traditional saunas collections.

Hydration and recovery

Heat makes you sweat, so fluids matter. Drink a glass or two of water before you go in, and replace what you lose afterward with water or an electrolyte drink. Avoid alcohol entirely around sauna use, since it impairs temperature regulation and raises the risk of fainting and dehydration.

Give yourself a few minutes to cool down before a cold shower or a cold plunge. If you pair heat with cold, ease into it and learn the basics first on our sauna and cold plunge collection.

Who should avoid or limit sauna use?

Some people should check with a healthcare provider before using a sauna. This includes anyone who is pregnant, has heart disease, has low or high blood pressure, has had a recent heart attack, or takes medication that affects blood pressure or temperature regulation. Older adults and people with chronic conditions should also seek advice first.

Children, anyone feeling unwell, and anyone under the influence of alcohol or drugs should not use a sauna. According to sources such as the Cleveland Clinic and Mayo Clinic, the heat is generally well tolerated by healthy adults, but individual health needs vary. This page is educational and is not medical advice, so talk with your clinician about your situation.

Warning signs to stop

Leave the sauna right away if you feel dizzy, faint, nauseous, short of breath, or notice a rapid or irregular heartbeat. These are signs of overheating or dehydration. Sit down in a cool area, sip water, and let your body recover. If symptoms do not ease quickly, seek medical help.

Frequently asked questions

Is it safe to use a sauna every day?

For many healthy adults, daily short sessions are fine. Keep each session to a comfortable length, stay hydrated, and stop if you feel unwell. If you have a health condition, ask your clinician what frequency is right for you.

Can you use a sauna with high blood pressure?

Possibly, but check with your doctor first. Heat changes blood pressure and heart rate, so people with cardiovascular conditions should get personal guidance before regular use.

How much water should you drink with sauna use?

Drink a glass or two before your session and replace fluids afterward. If you sweat heavily or use the sauna often, an electrolyte drink helps restore what you lose.
