Saunas offer relaxation and health benefits if a person does not overdo it, especially if they are sauna novices. Spending too much time in a sauna is not good for the body and can present health risks.
Saunas are generally without health risks, but people with high blood pressure, who are on medications or who have heart disease should consult a doctor before using saunas. Saunas are also not recommended for children or the elderly.
A 10- to 20-minute session is the right amount of time to spend in a sauna or steam room. In this period, a body can work up a good amount of sweat. Experienced sauna users can spend more time in a sauna, but beginners should not exceed the 10- to 20-minute range.
Any one who spends too much time in a sauna or steam room, runs the risk of becoming dehydrated or overheated and may faint after exiting the sauna. Individuals should drink plenty of water before, during and after using a sauna for this reason.
