Insufficient sleep is most commonly a result of a late bedtime and/or early wake time, or difficulties falling asleep or staying asleep throughout the night. Although one or two hours of sleep loss may not appear to be significant, there is an cumulative effect when repeated each night which can lead to devastating effects on our performance, our health, our waistline and much more.
Sleep plays a vital role and is considered to be a fundamental pillar for our health and well-being.
Sleep is not a passive ‘shut down’ state but rather an altered physiological state that cycles between NREM and REM sleep.
Timing of sleep is dependent on two main processes: the circadian rhythm and the homeostatic pressure for sleep.
