These are some of the physical effects of staying up too late

1. Direct health hazards:

Corpulence

The less you sleep, the higher your BMI. For example, a study that followed 500 people for 13 years found that those who slept less than six hours a night were 7.5 times more likely to have a higher BMI.

Increased risk of diabetes

Among middle aged and older adults, those who slept six hours were 1.7 times more likely to develop diabetes than those who slept seven to eight hours a day, and 2.5 times more likely to sleep less than five hours.

Increased risk of cardiovascular disease

Middle aged people without coronary heart disease were monitored for 10 years and found a 45% higher risk of developing coronary heart disease within 10 years of getting less than 5 hours of sleep per night.

Increased mortality from a variety of diseases

For people already suffering from a variety of potentially fatal diseases, reducing sleep time increases mortality.

Neurologically

Sleep deprivation reduces attention and alertness, which in turn reduces overall cognitive function, such as affecting the emotional system, causing depression and anxiety, as well as learning and memory.

2. Collateral damage

People who stay up late for long periods of time are not only affected by their physical health, but also by their performance at work and in life. The consequences may be more serious.

Tired driving

According to the American Academy of Sleep Medicine, about one in five car crashes is related to tired driving, with more than 80,000 people falling asleep at the wheel every day and 250,000 accidents related to sleep every year. As noted above, sleep loss can reduce attention and alertness, but people who don’t stay up all night but sleep less over the long term are more likely to have an accident than people who don’t sleep at all. Instead, people who haven’t slept all night tend to think about not driving, even when driving, trying to keep their spirits up. Chronically sleep deprived people tend to lack this awareness and overestimate their alertness, which is actually not enough to cope with danger.

Certain areas of expertise

Plenty of sleep is also needed for many professional skills. A 2004 study, for example, found that residents who slept less than four hours a day made twice as many mistakes as those who slept seven hours.

So the long-term stay up this kind of thing, both on the body of the chronic injury, but also because easy to make mistakes caused by the instant tragedy, or avoid it.

Finally, the usual FAQ:

How much sleep is best per day?

There is no perfect number, everyone’s personality is different, and so is the amount of sleep. Everyone may need a different amount of sleep each day, such as going to bed late the night before and needing more sleep the next day to make up for it. In general, if you wake up tired in the morning, doze during the day, or take a long nap, you’re not getting enough sleep. If you want to determine a suitable sleep time, the best is in the holiday, do not play too crazy, do not deliberately set a time to go to bed and wake up, so that a few days can know how much sleep they need.

2. Sleep Less or sleep more?

None of them are. Unless you’re born with a low or high need for sleep, most people have an upside down U-shaped relationship between the benefits of sleep and time, with the best in the middle, and the risks of being too short or too long. Most of the direct effects on health are U-shaped, meaning that too little or too much sleep is associated with increased obesity, diabetes and cardiovascular risk, among other things.

3. What if you don’t get more than seven hours of sleep for a long time because of work?

Caffeinated foods are essential if you want to stay at work, not just to keep us awake, but to help maintain cognitive function and alertness, reduce the chance of making mistakes at work and in life.

One night is not enough to get your body back on its feet. Months of staying up late can take weeks of extended sleep. You may start with 10 hours of sleep a day, but you’ll get back to normal sleep. In the meantime, try to avoid caffeinated foods.
