The results are broken down to optimize your REM and non-REM Sleep-wake cycle disorder, also known as circadian rhythm disorder, is when the internal body clock is out of sync with natural light and dark cycles. What Impacts Circadian Rhythms?Age. As infants and children age, the sleep-wake schedule shifts, and the needed amount of sleep (10) tapers off.Blue Light Exposure. Blue light waves (12) are found in fluorescent and LED lights and electronic screens, such as phones, laptops, and television.Jet Lag and Daylight Saving Time. Shift Work. Caffeine. 3. In people with sleep apnea, breathing problems kick in during deep sleep stages, disrupting the stage and making a person fall back into the lighter stages of sleep, where breathing is easier. It can refer to any process that originates within an organism (i.e., endogenous) and responds to the environment (entrained by the environment). Irregular sleep-wake cycle . The suprachiasmatic nucleus projects to the pineal gland to release melatonin, which promotes sleep.
