Differential BenefitsSlow wave sleep helps you recover physically while REM sleep helps you recover mentally. The amount of time you spend in these phases tends to decrease with age, which means the quality of your sleep and your body’s ability to recover also decrease with age.
The Circadian RhythmThe word circadian was coined from two Latin words: circa (around in English) and dia (day in English). Thus, circadian rhythm refers to the physiological cycle of different processes that happen over a time span of about 24 hours. These processes dictate your sleep cycle and can be greatly affected by 3 factors: • Light Light has probably the most significant effect. Staring into a light for 30 minutes or so can practically reset your circadian rhythm regardless of what time of day it is. More commonly, the rising of the sun and light striking your eyes trigger the transition to a new cycle. • Time The time of day, your daily schedule, and the order in which you perform tasks can all impact your sleep-wake cycle. • Melatonin Melatonin is the hormone that causes sleepiness and controls body temperature. This hormone is produced in a predictable yet regular cycle, increasing after dark and decreasing before dawn. Researchers believe that the regularity of melatonin production helps keep the sleep-wake cycle on track.
