Insomnia → 39°C golden rule
The cause of insomnia lies in the disturbance of the autonomic nervous system!
The causes of insomnia can be broadly classified into five categories.
There are various causes, but all of them lie in the disturbance of the autonomic nervous system. If the sympathetic nervous system (tension state) is dominant due to the above causes, the head becomes clear and it is difficult to fall asleep, resulting in insomnia. In other words, all you have to do is create a body in which the parasympathetic nerves, which are in a state of relaxation, dominate.
The golden rule of 39°C for insomnia relief
This chart shows the balance between temperature and autonomic nerves. You can see how a difference of just 2°C can change the balance of the autonomic nervous system.
From this graph, the sympathetic nervous system rapidly increases at 41℃, and the parasympathetic nervous system becomes dominant at 39℃.
On the other hand, if the temperature is low, the body (internal organs) will not warm up easily, so the temperature of the bath or sauna tends to be high for the purpose of warming up.
Ruffalo hot spring warms the internal organs at 39℃
This temperature is the focus of Rufflo hot springs. While keeping the room temperature at 39°C, the power of minerals warms the deep part of the internal organs. This is achieved by raising the body temperature with the power of one's own metabolism without relying on facilities. The ideal environment for relaxing and warming your body at the same time dramatically improves your sleep quality.
