The golden rule? Listen to your body!
There is no hard and fast rule to how long you should stay in a sauna. The ‘right’ duration varies from person to person and depends on your experience, your physical fitness and how you feel in the moment. But one thing is sure: if you feel dizzy or unwell, you must leave the sauna immediately. Forcing yourself is NEVER a good thing.
For most beginners, six to eight minutes per session is perfect. This gives your body the chance to acclimate to the intense heat. Experienced sauna bathers can usually stay in the sauna for 10 to 15 minutes, depending on the type of sauna. In hotter saunas, it’s best to keep your sessions a bit shorter. Also, it’s less hot on the lower benches than on the top ones, a handy little tip for those of you who want to start slowly.
A well-structured sauna experience generally consists of three parts:
This variation allows your body to benefit as well as recuperate optimally from the heat. Drink enough water (obviously, not in the sauna itself) and take regular breaks. Do also make use of the baths, pools and relaxation areas in our complex: from Jacuzzis to a salt room with halotherapy or a calming Tibetan singing bowls session in the relaxation area in the garden (next to the swimming lake).
You may be tempted to stay in the sauna just that little bit longer but longer isn’t necessarily better for you. You will already experience the health benefits of the sauna after a few minutes. Staying too long in the sauna may cause dehydration, headaches, a drop in blood pressure and even nausea. Not cooling down properly can have negative effects too.
A short, but well-structured sauna moment is a lot more beneficial that one long session in which you exceed your limits. By listening to your body, alternating between heat, cold and rest and by drinking enough water, you will get the most out of your sauna visit.
Come and relax at Thermae Grimbergen, where relaxation and health go hand in hand!
