This warm stimulus stimulates reflection to the cerebral cortex and inhibits the cerebral cortex. It is excited sympathetic nerves that smoothly transition to parasympathetic nerves. After the parasympathetic nerve is excited, the person is in a quiet resting state, thereby improving sleep and eliminating insomnia.
