Many fitness clubs have saunas, which may suggest that it is best to use them immediately after training.
But this is a big mistake! Never enter the sauna immediately after exercise.
In this room there is a very high temperature and humidity – in such conditions the body sweats and it loses water and electrolytes; the heart works at a speed of up to 140-160 beats per minute and breathing becomes shallow and accelerates. All of this makes your body get tired. Therefore, going into the sauna right after an exhausting exercise, especially aerobic, will make us more fatigued instead of giving us good rest.
After exercise the heart needs to calm down and regain normal body temperature – in the sauna this is impossible, because the body temperature rises up to 40 degrees Celsius and speeds up the heart rate. Such a state is not only harmful but dangerous to your health – and it may result in overheating of the body, unconsciousness, and in extreme cases even heart attack.
Instead of going in the sauna after a workout you should use exercise-cooling (cool-down) and make up the lost fluids. In this way, your body will regain balance, calm down, and rest.
The above-mentioned contraindications apply only to the time from several minutes to several hours after the workout. After the body has had a chance to recover fully, the sauna is completely safe.
