During sleep the body actively restores it's energy and condition. However it is frequently disturbed by mental activity, emotional stress. The easy and mostly available way to cure insomnia - sleeping pills. But is this a solution?

Last week an experimental 'sleep clock', which determines and controls sleep disorders was introduced in Summerwille, Massachusetts. It is worn on the head and special algorithms determine the sleep stages of the wearer,  sources of sleep disorders and nightmares, and what calms the person and helps to sleep better. So it's us who decides whether 'zeo sleep clock' is just based on placebo effect or new scientific marvel.
