The purpose of the sleep aid is to assist insomniacs to fall asleep. Therefore, to achieve this purpose, there are actually several ways, and different ways have different principles.
The first type is to use light sleep optimization technology to affect the secretion of human melatonin through specific light irradiation, and affect the time of work and rest to achieve the effect of sleep aid; The second type is to stimulate the acupuncture points in the palm, and the response of the stimulation is then transmitted to the brain, so that the brain secretes sleep substances to achieve the effect of sleep aid;
The third type is to use the release of white noise, to integrate a single frequency of noise into white noise, and to shield other noises to create a “quiet environment”, which is a bit like a baby sleeping, simulating the sound of a mother’s body; The fourth type is to use biomimetic microcurrents to stimulate the brain, affecting the brain to release special brain waves, so that the brain can secrete substances that help sleep, and achieve the effect of sleep aid.
