Memory levels, the ability to mentally focus and a happier state, will lead to high levels of productivity following a good night's sleep. With society geared around an early start, it makes sense to get to bed at an early hour, rise early and seize the day.
Sleeping early or late, the study said, adversely affects the body's internal clock or what is known as 'circadian rhythm' — a natural process that regulates sleep-wake circle — and certain metabolic processes.
Another downside of going to bed too early is that it can cause problematic sleep conditioning. This occurs when you teach your brain to associate arousing activities with the act of laying down in bed.
You could live longer
Studies have shown that adults who habitually sleep less than six and a half hours of per night are more susceptible to type 2 diabetes, heart disease, and hypertension. Even with a healthy diet and regular gym time, an earlier bedtime can be a huge plus for your longevity.
School-age children should go to bed between 8:00 and 9:00 p.m. Teens should try to go to bed between 9:00 and 10:00 p.m. Adults should try to go to sleep between 10:00 and 11:00 p.m.
“There is no such thing as a “fixed or ideal time” to go to bed which will suit all individuals. It is generally advisable to fall asleep between 10 pm to midnight as for most people this is when the circadian rhythm is at a point that favours falling asleep.”
This all depends upon how late, and how regular, a person's sleep patterns are. For example, falling to sleep at 4 am and waking at 12 pm will cause a person to miss out on a large amount of daylight, especially in winter. This can be problematic for various reasons, including our physical and emotional health.
Some studies have found that people who go to bed late and have trouble waking up in the morning are more likely to have a shortened lifespan, in addition to a much higher risk of psychological disorders and diabetes.
Most adults need 7 or more hours of good-quality sleep on a regular schedule each night. Getting enough sleep isn't only about total hours of sleep. It's also important to get good-quality sleep on a regular schedule so you feel rested when you wake up.
Some may even wonder if sleeping more could make them taller. A few studies have found that sleeping more in childhood and adolescence is associated with growing taller, though there is not enough evidence to say whether sleeping more increases a person's adult height.
People may fall asleep early because of something else, like depression, alcohol use or sleep apnea. Or they may nap during the day, which makes them wake early in the morning. So, we screen for depression and mood disorders, eliminate daytime napping or treat them for sleep apnea.
Yes and no. It is unhealthy to have irregular sleep patterns. If you regularly go to bed at 5 and sleep well, it can be healthy. You should somehow make it dark in your bedroom and also quiet, so you can sleep well.
Insufficient levels of sleep and circadian misalignment can disrupt many bodily processes, putting us at increased risk of cardiovascular disease, cancer, and diabetes.”
The circadian rhythm is controlled by a tiny region at the base of the brain called the suprachiasmatic nucleus (SCN), which makes us feel sleepy in the evening by sending a signal to the body to release the snooze-inducing hormone melatonin, which also lowers our body temperature.
“This large study suggests that going to sleep between 10 and 11pm could be the sweet spot for most people to keep their heart healthy long-term.
Daily rhythm helps our subconscious know when its time to slow down and get some sleep. Chaotic hours are likely to lead to sleep issues. The best hours for regenerative sleep for most people are between 10pm and 2am, so getting to bed before 10 can make a difference, although this varies between individuals.
It's up to the individual to find their best time to go to sleep and wake up, but as a rule of thumb: adults need around 8 hours of sleep a night (give or take), so a sleep schedule of 10pm to 6am, or 11pm to 7am may work well for you.
One reason for having trouble waking up is sleep inertia, a brief time when the body transitions from sleep to being awake. Sleep inertia can make a person feel groggy, disoriented, and even cognitively impaired immediately after waking.
