In Japanese saunas, the basic routine is to warm up in the sauna room, cool down in the cold plunge bath, and rest during outdoor air bathing. Repeating this 2 to 3 times makes it easier to feel a deep relaxed state, called "totonou".
For beginners, the key is not the number of minutes or rounds, but not pushing yourself. Before you feel overheated, extremely cold, or a pounding heartbeat, move on to the next step.
| Step | Suggested time for beginners | Point |
|---|---|---|
| ① Sauna room | 5 to 8 min | Start on the lower or middle bench. Leave when you feel warmed up and sweaty |
| ② Cold plunge bath | 30 sec to 1 min | Rinse off first. Get out before you get too cold |
| ③ Outdoor air bath | 5 to 10 min | Sit in a chair and rest. This is where "totonou" happens |
Repeat this for 2 to 3 sets. Rehydrate between each set.
Temperatures vary by facility, but are usually around 80 to 100°C. Upper benches are hotter, so beginners should start on the lower or middle bench. Once seated, close your eyes and focus on your breathing. Japanese saunas are usually quiet.
When sweat starts running down your forehead and you feel warmed from the inside, that is the time to leave. Time is only a guideline, so do not turn it into a test of endurance. Before leaving, it is polite to wipe away the sweat from where you were sitting.
Do not jump in immediately. First, rinse with water from your feet to your upper body, and finally over your head. In many facilities, you should shower off the sauna sweat before entering. This is also part of keeping the cold plunge bath clean.
Water temperature is usually around 15 to 18°C, depending on the facility. Many people get used to the cold after about 30 seconds. Get out once the surface of your body has cooled and your breathing has settled. If you get too cold, it becomes harder to warm up during the next outdoor rest, so beginners should keep it short.
After leaving the cold plunge bath, lightly dry off and sit down to rest. This is the "totonou" stage. After a few minutes, your body may feel lighter and you may be wrapped in deep relaxation. The outdoor air bath is often skipped, but if you leave it out, the experience tends to feel less complete.
The feeling of "totonou" is often explained as the autonomic nervous system shifting due to the temperature difference between the sauna and the cold plunge bath. However, everyone experiences it differently, and it is not something to force. The cultural background is covered in What is "totonou"?.
Saunas place stress on the body. Keep these points in mind.
