What is Löyly ?
※Löyly (pronounced “low-lu”) in a sauna is when you pour water over the hot stones. This creates a burst of hot, humid steam, making the sauna feel hotter. It’s a key part of the sauna experience in many cultures, like in Finland, and is often done for a more intense heat.
Many people wear sauna hats to protect their hair from the intense heat of löyly, which can feel like it’s burning. We even sell our own original sauna hats here!
How to “TOTONOU” in the sauna
First, you need to understand the basic cycle
“To achieve the ‘TOTONOU’ state in a sauna, follow these phases:
- Sauna (Heat): Warm your body thoroughly in the sauna.
- Cool-down: Quickly cool your body with cold water or air.
- Rest: Relax in a quiet space, ideally outdoors, to recover.
‘TOTONOU’ is the deeply relaxed and clear-headed feeling that can occur during the Rest phase, often intensified by the contrast between the heat and cold.”
