How Sleep Aids Work

The principle of sound-light modulation: Brain waves respond to light stimulation in a dependent manner. Specific sound combinations can alter brain wave activity. When two precisely controlled sound rhythms are transmitted to the brain through both ears, they induce brain wave activity to tend towards the same frequency as the sound rhythms. By selecting appropriate frequency sound signals, brain waves can be modulated to enter a desired frequency; for example, a gentle rhythm in both ears can induce a relaxed (alpha wave) or sleep-inducing (theta wave) state.

 

The principle of electrical stimulation: All activities of the human brain are bioelectrical activities. All our thoughts, sensations, and physical movements are based on microcurrents flowing through the brain. Applying weak electrical pulses to the nervous system can alter a person's physiological and psychological state. It is generally believed that repetitive and monotonous electrical stimulation with low-frequency pulses induces diffuse inhibition in the cerebral cortex and subcortical structures, causing active inhibition of the reticular formation by the cortex, thus leading to sleep.

 

The principle of traditional Chinese medicine acupuncture is to use a specific magnetic field to act on any acupoint on the human body, such as Neiguan, Daling, Shenmen, Zusanli, and Sanyinjiao. By selecting acupoints along the meridian and treating according to syndrome differentiation, sleep quality can be improved and sleep can be aided.
