Frequently changing sleep hours can increase the risk of insomnia and cause many other health problems. For people who have difficulty sleeping, going to bed without fixed hours will send mixed signals to the brain, making it even more difficult for the body to fall asleep at night.
Adjusting the biological clock inside the body
Going to bed and waking up at the same time each day helps establish a regular sleep pattern, supports healthy sleep and strengthens the natural sleep-wake cycle (biological rhythm). This helps the body easily recognize exactly when to rest and when to wake up.
A stable circadian rhythm will promote the release of sleep-supporting hormones at the right time at night, while also enhancing alertness during the day. To strengthen this natural circadian rhythm, you need to maintain a uniform bedtime and wake-up time even on weekends.
Improve sleep quality and REM cycle
In addition to helping you fall asleep more easily, maintaining a regular sleep schedule also supports healthy sleep patterns and improves overall sleep quality. Synchronizing your personal schedule with your natural circadian rhythm helps you sleep deeper and be more alert during the day.
Conversely, if there is no stable sleep schedule or trying to sleep at times contrary to the circadian rhythm, the body will be interrupted in the natural transition through 4 stages of sleep. This disruption can lead to a decrease in the amount of REM sleep - an important stage for mental and memory recovery.
Building natural reflexes and healthy habits for sleep
Establish a structured evening routine that helps the body form a reflex to predict sleep hours and automatically feel tired and sleepy when that time approaches. Thanks to this, you no longer have to face the discomfort of lying awake for 20-30 minutes each night.
In addition, setting a bedtime also creates a foundation for easy implementation of other healthy habits such as limiting late-night eating, reducing alcohol consumption, controlling caffeine intake and maintaining a reasonable short nap.
