Sleep is arguably the most essential part of everyday life, especially during the stages of early development. There are two sleep stages: Non-Rapid Eye Movement (NREM) and Rapid Eye Movement (REM). NREM is sometimes called “quiet” sleep. Deep states of NREM sleep increases blood supply to the muscles, restores energy, and releases essential hormones for growth and development. Tissue growth and repair also occur during this state. REM sleep, also known as “active” sleep, is the dreaming stage of sleep. The brain becomes active, and the body becomes immobile, with irregular breathing and heart rates.
A healthy sleeping schedule is imperative to ensure proper physical, mental, and emotional development. It can be difficult or even impossible for children with disordered sleep to get enough sleep. At least one study has found that six-year-old children with a pattern of short sleep duration at age 2.5 had higher levels of specific cognitive deficits and hyperactivity in comparison to their peers. Though research in this field is still emerging, the existing literature makes it evident that there is a relationship between sleep and childhood development.
