As the proverb says, the early bird gets the worm, but what if you're not an early bird. What if you're more like a night owl. While some people jump from the bed as soon as their eyes pop open, others are quite content to fall back into blissful slumber for several minutes and even hours.
Waking early or staying up late seems to be hereditary based on a study involving twins and sleep preference. Your body has a biological clock that determines when it wants to sleep, referred to as the circadian rhythm. The circadian rhythm is a 24-hour rhythm that controls functions such as the immune system, gastrointestinal system and liver. It allows these systems to synchronize various biological processes to respond to daily habits, such as daylight exposure or meal times.
The circadian rhythm is generated by the molecular circadian clock, found in almost every cell of mammals. The molecular clock is expressed by the cycle of circadian genes throughout a 24-hour period. The circadian clock itself is located in the hypothalamus in the brain and is regulated by factors such as light and eating.
Delayed sleeping — another term for night owl syndrome — is more common among late adolescents and studies show that sleep times can shift two to three hours during the teens to early adulthood years. Universities have found improvement in delaying class schedules even a few hours to accommodate this trend.
But if you stay up too late, it becomes harder to get up in the morning. And too much sleeping in can be bad for you, not to mention those late-to-work issues. One study discovered a distinct correlation between depression and those with the "eveningness" trait.
Looking at the research, perhaps it's time to switch to "morningness." But is it even possible to train yourself into becoming a morning person — that's assuming you're willing to try?
According to scientists, it's more important to work on a consistent sleep schedule. Then you can gradually make a shift in your routine. Up to one-third of U.S. adults report that they consistently sleep less than the recommended seven to eight hours per night. A consistent sleep schedule may help you to maintain or correct your body's clock so that you can regularly achieve high-quality sleep.
The body responds to habits and patterns in signals. Choosing to stay up a little longer is the same kind of behavioral signal as choosing to go to bed. An active effort to repair or maintain your sleep schedule can help to reinforce better routines. Once you achieve higher quality sleep through a consistent sleep schedule, you may notice these health benefits:
How can you tell if you need to improve your sleep schedule? You may notice symptoms like daytime sleepiness, trouble falling or staying asleep, and struggling to get up in the morning. You may also notice that you have issues with daily motor skills tasks or cognitive problems related to focus and memory. Even if you don’t experience these symptoms, it’s always a good idea to optimize your sleep schedule and keep your body clock on track.
Many elements of our daily environments can contribute to the disruption of the circadian rhythm. This, in turn, may lead to acute or chronic sleep-related conditions, including diabetes, cardiovascular disease and cancer. Here are some of the factors that can negatively affect your sleep schedule:
If you are struggling with sleep-related issues and want to improve your sleep schedule or ease the morning wake-up call, you can do so by creating routines. Routines train your body to respond to certain behaviors in a way that supports better sleep schedules. Once you're getting quality sleep, you can gradually shift your sleep and wake times to become more of an early riser. Try these tips to help you set a better sleep schedule:
