Message from experts

When you warm up your body, endorphins, a chemical in your brain, are secreted, which makes you feel relaxed and happy, increasing your sense of well-being.
In addition, the parasympathetic nervous system, which restores the body, becomes dominant, and it is expected that internal organ function and immune function will improve.
