The disadvantage of sauna is that it is a fashionable and healthy leisure way. After sweating, the whole body relaxes and fatigue disappears, so many people who are nervous at work are quite good at it. However, medical experts warn that frequent sauna may become the chief culprit of male infertility. In Finland, the birthplace of sauna, the incidence of male infertility is quite high, which is not unrelated to the local people's love for sauna.

Sauna "dizzy hall" has nothing to do with age. This happens for the following reasons:
1, dizziness or shock caused by hypoglycemia. Some people will feel weak and even erratic after a hot bath or sauna.
2. Insufficient blood supply to the brain. Hot water or steam can dilate peripheral blood vessels, accelerate blood flow, and the brain is prone to mild blood supply deficiency, leading to dizziness.
3. The oxygen supply is reduced. Most bathrooms have small space. If the seal is too tight, the partial pressure of oxygen in the indoor air will also decrease, which will affect the oxygen supply.
4. Postural vertigo. This phenomenon will occur when you bend your head and wash your lower limbs for a long time.
