1) Don’t Stay in Too Long

15 minutes at a time is generally considered the max, though some more experienced may be able to stay longer. The length of time the body can tolerate will vary from person to person. If you are sensitive to heat, start off with a short stay.
2) Cool Down
There is a long Finnish tradition of going straight from the sauna into the snow and we advise a dip in the lake if you can! A gradual cool down is easier though. For a less extreme way to cool your body down, splash water on your body at the lake. Don’t feel the need to impress-do what feels right for you.
3) Rest
Relax afterward. Let your body recuperate before doing the hot, cold, relaxation circuit again.
Some bodies can’t tolerate doing the sauna more than twice, and the second time may be shorter. Use your judgement.
4) Rehydrate
Drink plenty of water before and after. You may want to eat something salty afterward too if you’ve sweated a lot.
5) Consider the Buddy System
Going into the sauna with a friend or family member is more fun, and means you have someone to keep an eye on you.
6) Consider Your Health
The heat of a sauna makes the heart work harder. Reasons to avoid the sauna include heart problems, pregnancy, high or low blood pressure, etc. If you have any concerns, check with your doctor first.
7) Never Drink Alcohol in the Sauna
Also, don’t go in right after a large meal or strenuous exercise.
8) Know that Saunas Can Burn
Too much time in the sauna at a too high temperature can lead to blistering. Jewellery heating up can scald too. Take care!
9) Monitor Your Body
If you start to feel dizzy, nauseous or have a headache, leave immediately. There is no point in taxing the body to extremes – especially not in the name of wellness. Moderation is key.
Saunas can be a great relaxing pleasure, so follow these safe sauna rules, check with your doctor if you have any questions and use common sense to get the most of your experience.
