Why can’t some people sweat in the sauna?


Sweating is a natural and necessary process that helps regulate body temperature. When the body temperature rises – for example, during physical exercise or in a warm environment like a sauna – the sweat glands produce sweat, which then evaporates on the skin’s surface, cooling the body. The size and activity of sweat glands can vary among individuals, which explains why some people sweat more than others.

Check the sauna – Is the temperature high enough?

Before addressing physiological issues, it’s worth noting that if someone isn’t sweating in the sauna, it could also be related to the sauna itself. Is the temperature high enough? Is the stove working properly? If the sauna is heated by wood, has the fire gone out? Are all the doors and windows tightly closed to prevent heat from escaping? If there is some problem with the sauna, even a person who usually sweats might not sweat as much as they should.

Why some people don’t sweat in the sauna – Physiological aspects

If the sauna is working properly, but someone still isn’t sweating, it’s likely related to their individual physiological traits. Age, gender, health status, and level of physical activity can influence the ability to sweat. For example, older people and those with certain illnesses, such as diabetes, may have a limited ability to sweat. Also, individuals who are less physically active may have less active sweat glands.

Anhidrosis – a rare but serious cause of lack of sweating

Anhidrosis is a condition where the body isn’t able to sweat, even though it should. This could be caused by damage to the sweat glands, which could be the result of injuries, burns, certain genetic conditions, or side effects from some medications. Anhidrosis can lead to serious health consequences, like overheating and heatstroke, so if you notice that you aren’t sweating even in very hot environments, you should consult a doctor.

Health effects of not sweating in the sauna

Not sweating in the sauna, even though you should, can lead to various health problems. The main risk is overheating, which can lead to heatstroke – a condition that requires immediate medical attention. Symptoms of overheating and heatstroke may include dizziness, nausea, increased heart rate, disorientation, and loss of consciousness. If you notice these symptoms in yourself or another person, immediately leave the sauna and call for medical help.

In the case of prolonged absence of sweating, consult a doctor. It could be a sign of anhidrosis or another serious disease that requires treatment.

In conclusion, sweating is a key element of body thermoregulation. If you notice that you aren’t sweating in the sauna, first check if the sauna is being heated correctly. If the sauna is working properly, but you still aren’t sweating, this could be related to your individual physiological characteristics or health status. In this case, it would be wise to consult a doctor. Remember that health should always be a priority.
