A sleep instrument is a physical therapy instrument aimed at helping the human body to sleep. It uses technologies such as electromagnetic stimulation and biomimetic waves to help people sleep. Sleep instruments can be divided into low-frequency electromagnetic stimulation to induce sleep, traditional biofeedback therapy, and digital frequency synthesis biomimetic waves.

  The mechanism of the sleep instrument: digital frequency synthesis biomimetic electrical waveform current stimulates the cerebellar parietal nucleus (FNS), and the cerebellar parietal nucleus directly projects upward to the thalamus and hypothalamus. The thalamus, hypothalamus, through the thalamus cortex, connect the collaterals, and connect with the cerebral cortex; start the neuroprotection of the central nervous system, improve the stability of the membrane potential of the brain nerve cells, reduce the excitability of the brain, improve and enhance the sleep function, and use FNS to treat insomnia. The internal environment of the nervous system can actively adjust the sleep/wake rhythm of patients, and improve the sleep disturbance caused by the increase of brain excitability. Actively adjust the sleep and wake rhythms, so as to achieve the purpose of non-drug treatment of insomnia.
