More important is that you stick to the same time, said Dr. Katherine Sharkey, an associate professor who studies sleep at the Warren Alpert Medical School of Brown University. Your body runs on circadian rhythm
What is the sleep-wake cycle? The sleep-wake cycle involves two pathways in your brain: a wake pathway and a sleep pathway. Each pathway has many neurotransmitters that send signals to determine whether you are awake or asleep. Under regular conditions, sleep occurs when the wake neurotransmitte...
Regulates Your Body Clock: Our bodies have a natural circadian rhythm that dictates when we feel sleepy and when we’re alert. A consistent sleep schedule helps synchronize your body clock with your chosen sleep times, making it easier to fall asleep and wake up at the desired hours. Enhances...
we get pretty much all of our deepest sleep in the first half of the night. This means that after just a few hours of sleep, our body has likely got all the deep sleep it needs.
Sleep syncing, also known as circadian synchronization, is theprocess of aligning our sleep patterns with our body's natural circadian rhythm. The circadian rhythm is a 24-hour internal clock that regulates various physiological processes, including the sleep-wake cycle. It governs when we feel ale...

The pineal gland in the brain produces melatonin, a hormone that regulates the body’s circadian rhythm or internal body clock. When it becomes dark, the body naturally releases the hormone, preparing us for sleep. “It regulates your sleep-wake cycle,” Bowman explained. “If it’s completel...
Controlling your sleep-wake cycle –Naturally, your body produces less cortisol levels at night and more in the morning. As such, it’s believed that cortisol may play a role in keeping you awake throughout the day, and symptoms of high cortisol levels in the morning are often noticeable. ...
That means that if you usually leave your phone to charge overnight, the optimized charging feature will slow down the charging process to 80% and will only complete the charging just before you wake up. Reduces Battery Wear:By limiting the amount of time your iPhone spends at 100% charge,...
Nicotine may alter the release of neurotransmitters that regulate the sleep-wake cycle (Guzmán-Marín et al., 2001) or stimulate wake-promoting neurons (Guzmán-Marín et al., 2001, Saint-Mleux et al., 2004, Sigalas et al., 2015). In addition, the amount and quality of sleep of the ...
