Saunas are widely praised for their relaxation and health benefits,but a recent case underscores a hidden danger: the potential for heat stroke.A report published in BMJ Case Reports reveals that extended sauna sessions, notably without proper hydration, can lead to severe health complications—even in individuals without obvious risk factors.
The report recounts the experience of a woman in her early 70s who collapsed after spending 45 minutes stretching in a sauna at her local gym. Found unconscious, she was rushed to the hospital, where doctors discovered her core body temperature had skyrocketed to a life-threatening 42°C—well above the normal range of 36.4°C.Her condition was dire, with dangerously low blood pressure, an elevated heart rate, and a subsequent seizure.
Heat stroke, though rare, is a medical emergency. It occurs when the body’s core temperature rises sharply, impairing brain function and potentially damaging vital organs. In this case, the woman’s kidneys and liver began to fail, and she showed signs of a minor heart attack and muscle tissue breakdown, a condition known as rhabdomyolysis.
Medical teams acted quickly, using wet towels and fans to cool her body while administering intravenous fluids and blood products to stabilize her condition. Within two hours of her temperature returning to normal, she regained consciousness, though she remained confused and drowsy for two days. By the third day, her mental clarity improved, and she experienced no further seizures during her 12-day hospital stay. After 26 days, she had nearly fully recovered, with only mild fatigue and slight liver function issues lingering.
What makes this case particularly striking is the woman’s lack of typical risk factors for heat stroke. While conditions like heart disease, lung disease, or heavy alcohol use often increase susceptibility, she had none of these. Her only pre-existing conditions were type 1 diabetes and an underactive thyroid. She was a regular gym-goer, non-smoker, and moderate drinker.Reflecting on the incident, she noted, “As a regular sauna user, I never suffered any issues and, on reflection, I believe I had not drunk enough water.”
This case is one of only ten similar incidents documented, three of which were fatal. The authors of the report emphasize that “the prognosis of heat stroke varies according to patient factors, particularly extremes of age.” They add, “Classical heat stroke in elderly people carries a mortality rate of [more than] 50%, and this increases further with each additional organ dysfunction.”
While saunas remain a popular wellness activity, this incident serves as a stark reminder of the importance of moderation and hydration. For those who enjoy saunas, especially older adults, it’s crucial to limit session durations, drink plenty of water, and be mindful of any signs of overheating. Heat stroke may be rare, but its consequences can be devastating.

Interview with Dr. Emily Carter, Emergency Medicine Specialist, on the Risks of Sauna-Induced Heat Stroke
archyde: Dr. Carter, thank you for joining us today. A recent case highlights the dangers of prolonged sauna use. How can individuals minimize their risk of heat stroke while still enjoying the benefits of saunas?
Dr. Carter: It’s essential to approach sauna use with caution, especially for older adults or those with underlying health conditions. Limiting sessions to 15-20 minutes and ensuring proper hydration before, during, and after sauna use can significantly reduce the risk.Listening to your body and stepping out at the first sign of dizziness or discomfort is also critical.
Archyde: What are the key warning signs of heat stroke that sauna users should watch for?
Dr. Carter: Symptoms like confusion, rapid heartbeat, nausea, and excessive sweating—or, conversely, a lack of sweating—are red flags. If you or someone else experiences these symptoms, it’s crucial to cool down promptly and seek medical attention.
Archyde: Thank you, Dr. Carter, for these valuable insights. Saunas can be a splendid tool for relaxation, but as this case shows, they must be used responsibly.
Understanding the Risks of Sauna Use: How to Prevent Heat stroke
Saunas are often celebrated for their relaxation and health benefits, but a recent case report published in BMJ Case Reports serves as a stark reminder of the potential dangers. The report details a severe instance of heat stroke following prolonged sauna use, which led to multiorgan failure. This alarming case underscores the importance of understanding the risks and taking precautions to ensure safe sauna practices.
Why Saunas Can Be Risky
Dr. Carter, a medical expert, explains that while saunas are generally safe when used responsibly, they can become hazardous if users overexert themselves or stay inside for too long. “The high temperatures in saunas can overwhelm the body’s ability to regulate its core temperature, leading to heat stroke,” he says. In the reported case, the patient experienced hyperthermia, which triggered a cascade of complications, including seizures, liver and kidney injury, and even a type 2 myocardial infarction.
Recognizing the Warning Signs
Early detection of heat stroke is critical. dr. Carter highlights the key symptoms to watch for: “Early symptoms include dizziness, nausea, headache, and confusion. As it progresses,individuals may experience a rapid heart rate,lack of sweating despite the heat,and even loss of consciousness.” In severe cases, like the one described, heat stroke can lead to multiorgan failure. Recognizing these signs early and seeking immediate medical attention can make all the difference.
standard Treatments for Heat Stroke
When it comes to treating heat stroke,rapid cooling is essential. “External cooling methods, such as ice packs, cold water immersion, or specialized cooling blankets, are first-line treatments,” Dr. Carter explains. Intravenous fluids are also administered to rehydrate the body and support organ function. In severe cases, additional interventions may be necesary to address complications like kidney failure or disseminated intravascular coagulation.
Tips for Sauna Enthusiasts
For those who enjoy saunas, Dr. Carter emphasizes the importance of moderation. “limit your time in the sauna to 15-20 minutes, and always listen to your body,” he advises. Staying hydrated before and after sessions is crucial, as is avoiding alcohol, which can impair the body’s ability to regulate temperature. “If you feel unwell at any point, exit the sauna promptly and cool down,” he adds.Using the sauna with a buddy, especially for beginners or those with underlying health conditions, is also recommended.
Conclusion: Stay Safe and Informed
As Dr.Carter aptly puts it, “Awareness and education are the best tools we have to prevent such incidents.” Saunas can be a wonderful way to relax and rejuvenate, but they must be approached with caution. By understanding the risks, recognizing the warning signs, and following safety guidelines, you can enjoy your sauna sessions responsibly and avoid severe health complications.
