How Head Spa Affects the Autonomic Nervous System

Why do you feel so sleepy after a head spa? It's a sign that your parasympathetic nervous system is dominant. We explain the relationship between the autonomic nervous system and head spa.

What is the Autonomic Nervous System?

The autonomic nervous system consists of two parts: the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system becomes dominant during activity and tension, while the parasympathetic nervous system becomes dominant during relaxation and sleep. In modern society, stress and irregular lifestyles tend to overactivate the sympathetic nervous system, making it easy for the autonomic nervous system to become unbalanced.

Why Head Spa Stimulates the Parasympathetic Nervous System

The head has a concentration of many acupuncture points and nerves, and appropriate stimulation can make the parasympathetic nervous system dominant. In particular, warm showers and careful massage of the scalp stimulate the vagus nerve, bringing about a state of deep relaxation.

Feeling sleepy during treatment is because the parasympathetic nervous system has become dominant and the body has entered its natural rest mode. This is a very good state, and after treatment you will feel refreshed both physically and mentally.

Regularly balancing the autonomic nervous system through head spa treatments can also lead to improved sleep quality and relief from chronic fatigue.
