Understanding Sleep Cycles
Sleep is a particular physiological state of the body, the opposite of wakefulness. Our reaction to the outside world decreases during sleep, but the brain does not stop operating. The change in sleep and wakefulness cycles is necessary for the existence of all higher-functioning animals. Mammals, birds, reptiles, and invertebrates sleep. Our desires to sleep or stay awake are mainly due to our circadian (from the Latin circa "about, around" + dies "day") rhythm. Every living being produces this daily rhythm. The adjusted mechanism counts approximately 24 hours and sends the necessary signals to the brain and other body parts.
