Fluctuating sleep hours: Many people have no set bedtime or wake-up time.However, the brain responds to artificial light as well, which means that constant exposure to indoor lighting as well as electronic devices like cell phones, tablets, televisions, and computers can interfere with typical signals that convey whether it’s day or night. Artificial light exposure: Biologically, the circadian rhythm developed to correspond to sunlight long before electricity was invented.Advanced or delayed sleep timing: Some people are extreme “early birds” or “night owls,” meaning that their sleep timing, also known as their sleep phase, is shifted forward or back by several hours.Shift work: People who work night shifts have to be awake when it’s dark and sleep when the sun’s out, disrupting normal circadian synchronization.Jet lag: Associated with rapid traveling across multiple time zones, jet lag occurs when the body’s internal clock is at odds with the day-night cycle at the travel destination.There are multiple ways for sleep routines and circadian rhythms to get thrown off-kilter: Research demonstrates that a well-synchronized circadian rhythm can contribute not only to healthy sleep but also to numerous other aspects of health.
In this way, circadian rhythm helps to synchronize our internal clock with our external environment.
When light exposure decreases at night, the signals switch to promote relaxation and sleep. When the eyes are exposed to light, the brain sends signals associated with wakefulness. Light exposure is an essential influence on circadian rhythm, which is closely aligned with the day-night cycle. Circadian rhythm is crucial to managing the delicate balance between sleep and wakefulness, helping us be alert or drowsy at the appropriate time. It is a 24-hour cycle that is part of the body’s internal clock.

What Is Circadian Rhythm?Ĭircadian rhythm is a principal driver of your sleep routine. With more repetition, the routine gets reinforced, facilitating increasingly stable sleep patterns over time. By creating habits and cues that promote sleep, the norm becomes falling asleep quickly and staying asleep through the night. Routines can make actions nearly automatic in numerous aspects of daily life, including sleep.Īctively cultivating a healthy sleep routine makes it easier to get the sleep you need on a consistent basis. Humans are often described as creatures of habit because we become conditioned to distinct patterns of behavior through repetition of certain cues and responses. It also provides a blueprint for people who are looking to optimize their sleep and be in a position to get the best sleep possible every night.

Knowing how to reset your sleep routine offers a way of resolving this type of sleep inconsistency. When that happens, bedtimes and wake-up times can fluctuate wildly, and a person may bounce back and forth between nights of too much and too little sleep. Unfortunately, many factors can throw a sleep routine out of whack. By following a standard schedule and healthy sleep habits, the mind and body become accustomed to a routine that includes plenty of high-quality sleep. One of the best ways to promote consistent sleep is having a healthy sleep routine.
For their mental and physical health, adults need between seven and nine hours of sleep, and it’s important that they get this sleep night after night.
