A good night’s sleep is vital for health. Examples of the consequences of sleep deprivation are impaired memory, lower school grades, depression, slowed reaction time, decreased immune function, adrenal fatigue, impaired sexual function, and an increased risk of uncontrolled weight gain.

“Stage two is also a light phase of sleep where you can be easily woken.
“Initially brain waves increase to produce sleep spindles which help ‘turn off’ the response to external noise and motion.
