Sauna heat exhaustion occurs when your body overheats due to prolonged exposure to high temperatures, typically between 150°F and 200°F. Key symptoms include heavy sweating, dizziness, nausea, rapid heartbeat, and extreme fatigue. If untreated, it can escalate to heatstroke, a serious medical emergency.
Quick Action Steps:
- Spot Symptoms Early: Look for sweating, dizziness, clammy skin, or confusion.
- Cool Down Immediately: Exit the sauna, move to a cooler area, and apply cool, damp cloths or take a lukewarm shower.
- Rehydrate Gradually: Sip water or electrolyte drinks slowly.
- Seek Medical Help: If symptoms persist for over an hour or worsen, call for emergency care.
Prevention Tips:
- Limit sauna sessions to 15-20 minutes.
- Stay hydrated before, during, and after use.
- Avoid alcohol or caffeine, which can dehydrate you.
- Acclimate gradually to heat and always sauna with a companion for safety.
Recognizing the signs early and following these steps can help prevent serious complications. If you're new to saunas or have health conditions, consult a doctor before use.
How To Treat Heat Exhaustion, Signs & Symptoms
Why Saunas Can Cause Heat Exhaustion
Saunas expose your body to extreme heat, with temperatures typically ranging from 150°F to 200°F. This level of heat puts a heavy strain on your body's cooling system, making it harder to regulate your temperature effectively [1]. When combined with high humidity, the risk of overheating increases significantly.
How Saunas Impact Body Temperature
In saunas with high humidity, sweat doesn't evaporate as it normally would. This limits your body's ability to cool down, causing your core temperature to rise quickly [1][3]. Without proper evaporation, your natural cooling system becomes less effective, leading to potential overheating.
Who Faces Greater Risks?
While heat exhaustion can affect anyone, some people are more vulnerable due to their body's reduced ability to handle extreme temperatures. Individuals with conditions like heart disease, diabetes, or obesity are at higher risk because their temperature regulation and circulation may already be compromised [1][3].
Other at-risk groups include older adults, first-time sauna users, those on certain medications (like diuretics or beta-blockers), and people who are dehydrated [1][3]. These factors can make it easier for heat exhaustion to develop, even during relatively short sessions.
Although the body can gradually adjust to heat over time, this adaptation takes days or weeks. Even with acclimation, sudden or prolonged exposure to high temperatures can still be dangerous [1][3].
Recognizing these risks can help you stay safe and spot early signs of heat exhaustion before it becomes a serious problem.
How to Spot Heat Exhaustion in a Sauna
Key Symptoms to Watch For
Heat exhaustion can set in quickly in the high temperatures of a sauna, often within just a few minutes of exposure [1]. When your body's cooling system becomes overwhelmed, several warning signs may appear.
Look out for these physical symptoms:
- Excessive sweating paired with cool, clammy skin
- Dizziness or feeling lightheaded
- Rapid heartbeat with a weak pulse
- Nausea or an upset stomach
- Severe fatigue and muscle weakness
- Headache
Standing up may cause a sudden drop in blood pressure, which can lead to fainting or falls [1][3]. This is particularly risky in a sauna, where injuries from falls or burns are a serious concern.
Signs Specific to Sauna Use
The sauna environment can amplify certain symptoms, making them more noticeable. While physical signs are often easier to spot, behavioral changes can also signal trouble.
Physical Symptoms:
- Goosebumps or an inability to cool down, even after stepping into a cooler space
- Sudden cessation of sweating
- Shortness of breath or a sensation of suffocation
Behavioral Changes:
- Confusion or trouble concentrating
- Sudden irritability or heightened anxiety
If you observe any of these signs - especially disorientation or dizziness - leave the sauna immediately. These symptoms signal that your body is struggling to regulate its temperature, and staying inside could lead to more serious health issues [1][3].
If the situation escalates to a body temperature above 103°F, severe confusion, or unconsciousness, this points to heat stroke. This is a medical emergency that requires immediate action [1][3].
Recognizing these warning signs early is essential to preventing further complications.
Steps to Treat Sauna Heat Exhaustion
How to Cool Down Quickly
If you notice any of the warning signs mentioned earlier, take action immediately to avoid worsening the situation. The first step? Move the person to a cooler, ventilated area. Help their body cool down by removing excess clothing.
You can also use cool, damp cloths or lightly mist their skin while fanning them. If possible, a cool (not ice-cold) shower can help. Avoid using freezing water - it can cause blood vessels to constrict, slowing the cooling process [1][2].
Rehydrating the Body
Once they're in a cooler environment, focus on rehydration. Offer small sips of room-temperature water or drinks with electrolytes. Drinking too much at once can lead to stomach discomfort, so go slow. Keep hydrating for several hours to fully replenish fluids [1][2].
When to Get Medical Help
Keep a close eye on symptoms during the first hour after treatment [1][3].
Call for emergency medical help if their body temperature goes above 103°F, symptoms last longer than an hour, or if they show signs like confusion, vomiting, seizures, or unconsciousness [1][3].
Even after they start feeling better, it's important to avoid saunas or any intense heat exposure for at least a week. This gives the body time to recover and restore its ability to regulate temperature [1].
Following these steps can address immediate concerns, but practicing sauna safety is the best way to prevent heat exhaustion in the first place.

Tips to Avoid Heat Exhaustion in Saunas
Safe Sauna Habits
To stay safe in a sauna, limit your sessions to 15-20 minutes and keep yourself hydrated by sipping water or electrolyte drinks throughout your time inside [1][3]. Always have water nearby and take small, frequent sips to maintain hydration [1][2].
"If you experience any symptoms of heat exhaustion, such as dizziness, nausea, or heavy sweating, exit the sauna immediately and seek medical help if necessary" [1][2][3].
Avoid drinking alcohol or caffeine before using a sauna, as these can speed up dehydration and raise your chances of heat exhaustion [1][3]. It’s also a good idea to sauna with a friend who can keep an eye on you and assist if needed [3].
Take breaks every 5-10 minutes to cool down and let your body recover. This process, known as acclimatization, helps your body adjust to the heat more effectively [2].
The type of sauna you use can also play a role in maintaining safety and comfort.
Picking the Right Sauna for You
Selecting the right sauna can reduce risks and make the experience safer, especially for beginners or those with medical conditions. Below is a quick comparison of common sauna types and their features:
| Sauna Type | Temperature Range | Safety Features |
|---|---|---|
| Infrared | 120-140°F | Provides gentle, direct heat; suitable for beginners or those sensitive to heat |
| Traditional | 150-185°F | Offers adjustable settings for a classic sauna experience |
| Steam | 110-115°F | Produces moist, low heat; ideal for those who prefer humidity |
Infrared saunas are often recommended for beginners or individuals with health concerns, as they warm the body directly without raising the air temperature as much [2].
When choosing a sauna, look for models with adjustable temperature settings and proper ventilation. Starting at lower temperatures and increasing gradually can help your body adapt [3][4]. Many modern saunas also include safety features like automatic shut-offs and temperature limiters to prevent overheating.
Where to Learn More About Sauna Safety
The American Red Cross shares updated advice on heat safety and first aid, including ways to prevent and manage heat-related illnesses [2][4]. For reliable health information on heat exhaustion - its symptoms, treatment, and prevention - check out WebMD and Mayo Clinic [1][3].
These resources offer practical advice, medical insights, and up-to-date research on heat-related conditions. The American Heart Association also suggests consulting a healthcare professional before starting regular sauna sessions, especially for those with existing health issues.
