Why is it that people get sleepy after warming their bodies?

We enter sleep after the body has gradually lowered its core temperature. You can see it in the way our hands and feet get warmer before sleep, as it’s where heat leaves the body. Blood vessels widen, heat dissipates from our hands and feet, and our core temperature lowers, making us sleepy.

That’s why nighttime is the right time for one more sauna trip. Not to rouse the body, but to wind it down to sleep.

This time, we want you to “keep your head cool and your feet warm.” Warm your feet without rushing blood to the head. This has been the ideal condition for comfortable sleep since ancient times. That’s why, instead of sitting, we want you to lay down first.

When you lie down, heat slowly transfers from your head to the toes in one direction; it does not circulate back.

Then, throw water into the hot stones. Doing so while lying down feels like someone tucking you into a cozy warm blanket.

Alternating between the heat and the shock of the cold bath resets the autonomic nerve, returning the body to its original calm state.

Then, when you finish your bath, apply a generous portion of lotion. The heat from the sauna softens the skin, allowing it to receive and absorb moisture.

And lastly, close your eyes. All the actions of your day will quietly sink in and become part of you, much like moisture on your skin. All that remains is sleep. So surrender yourself to the night of this island.
You may find the kind of deep rest that only exists here.
