By Sleep is a natural state of rest, harmony and recuperation that has many physical and mental benefits. The word “sleep” comes from the Old English word “slǣpan” which means “to slumber or nod.”
Usually adults sleep seven to nine hours per night; yet 10% of people get less than six hours per night. When we sleep our brains undergo dramatic changes. Brain wave activity slows down, muscles relax and repair injuries occur in cells throughout the body. For some people, such as babies or young children, periods of rapid eye movement (REM) enter the cycle with less deep sleep occurring overall which may explain why they need more zzzs than most adults!

Non-rem is divided into three categories, deep sleep, light sleep, and REM.

Some experts identify four different stages to this final stage of relaxation ranging from very low frequency activity at 1Hz, to Stage 4 which ranges between 12Hz – 15Hz.
It’s thought that these different phases serve biological functions depending on what time they occur during the 24 hour cycle. For example, non-REM stage 3 which are periods of 25% delta wave.
