(ECNS)-- A slow wave sleep machine from Canada designed for better sleep attracted many visitors at the 4th China International Import Expo (CIIE) held in Shanghai.
Visitors enjoyed a twenty-minute sleep by using this machine.
It is used to adjust the deep sleep state of the brain by generating charged particle waves that are helpful for sleep.
This is the fourth time that the sleep machine has been exhibited at CIIE.
It was an exhibit at the first CIIE and now it is commercially available in the Chinese market.
