People are very busy and have many pressures that make them anxious. One of the problems caused by anxiety is insomnia. Nighty Night is a wearable wristband that combines traditional Chinese acupressure with modern technology by using a low-frequency pulse current to stimulate certain acupoints that can improve sleep quality. It does not require the user’s active involvement but can also easily resolve the problem of insomnia. It perfectly combines the old with the new and brings more potential for sleep and health.
