Sleep routine mainly revolves around the factors that are directly under our control — from sleeping and waking up around the same time to good sleep duration. Sleeping and waking up on time and healthy sleep duration are important to get a fulfilling sleep so that you wake up feeling refreshed.
Different individuals require different amounts of sleep to function normally. It can vary with age, lifestyle, physical and mental stress. A minimum of 6 hours of sleep is necessary to flush out neurotoxins accumulated in the body during the day. It is believed that the accumulation of these neurotoxins may cause serious health issues like Alzheimer’s disease.
Humans have a natural body clock which is governed by the hormone melatonin secreted by the pineal gland in the brain. At night, melatonin levels go up, inducing sleepiness. In the morning the melatonin levels go down. This melatonin cycle is governed by light, specifically the blue light (abundantly available in sunlight). Aligning sleep time with the time when the body is most receptive to fall asleep (when the melatonin levels are going up) allows the body to quickly wind down and get the most out of it. Electronic gadget displays emit a high amount of blue light directly in the faces, which affects the melatonin secretion, and makes it difficult to fall asleep even when we intend to, disturbing the circadian rhythm. Avoiding the use of such screens at least 30 minutes before bedtime can significantly reduce the time it takes to fall asleep.
A good sleep composition includes a sufficient amount of Deep and REM sleeps as well as a high sleep efficiency. Deep sleep is responsible for physical restoration and recovery while REM sleep is related to memory consolidation. Both are equally important for a sound sleep. Dozee’s intelligent algorithm identifies these stages along with light sleep. Ideally, an adult human should get about 2 hours of Deep and REM sleeps in an 8-hour sleep.
