Getting up early is not always for you

You don't have to be an "early riser" for several reasons.

Firstly, the ability to get up early depends very much on genetics.

In other words, many people are really born with the tendency to sleep in.

Scientist Xu once researched this topic: there is a family in San Francisco, USA, who used to get up at 3 or 4 am and go to bed at 6 or 7 pm every night.

They transferred a section of the family's genes to mice and found that the mice automatically learned to go to bed early and wake up early without being trained.

The 2017 Nobel Prize in Physiology or Medicine, was awarded to research into the mechanism of the biological clock.

The human body's biological clock is not a matter of habit, but of genes. There are two types of sleep: the "early morning type" and the "night type".

People with the "early morning" type tend to get excited in the morning and are naturally able to sleep less and be more energetic, while people with the "nocturnal" type tend to get excited at night and therefore tend to sleep later and wake up later.

According to sleep expert Neil Stanley, there are six genes in the body that have been shown to be linked to sleep type.

The New Yorker, a leading American magazine, once published a study: 40% of people are biologically unfit to go to bed early and get up early.

In other words, it's likely that early risers like Cook are not self-disciplined, but rather "gifted".

If you want to go to bed early and wake up early like him and succeed in your career, it would be better to resort to genetic engineering than to adjust yourself.

Secondly, people have a natural time to wake up from sleep. It is more important to wake up at your natural waking time than to force yourself to get up early.

Everyone has a natural time to wake up. A study by an Oxford University academic called Paul Kelly found that for a 10-year-old, the natural time to wake up from sleep is 6.30am.

At 16 it's 8am; at 18 it's 9am. If you get them up after their natural waking time, they will be able to go to class fully refreshed and study 10% more efficiently.

This is the reason why Zhejiang delayed school hours for primary school children some time ago.

Paul Kelly has studied not only the work schedule of children, but also that of working people: in fact, the 9 to 5 work schedule is very unreasonable.

Adults don't get much less sleep than children. Add to that commuting and making breakfast for the children and you are likely to be up at six or seven.

Throughout life, people tend to get up early as children and as they get older, they shift more and more towards going to bed later and getting up later.

It is only after the age of 50 that the shift towards early to bed and early to rise begins again.

So, Kelly says, you want an adult under the age of 55 to sit in the office and start work at nine o'clock sharp.

It will lead to "sick, tired and stressed employees".

"Early to bed and early to rise" is important, but only some people can do it.

What works for everyone is to follow your own routine and wake up naturally.

You don't have to worry about not going to bed early and getting up early, because as long as you wake up feeling refreshed.

That's a quality sleep.

A good night's sleep means that you must get a certain amount of sleep.

The general rule is 8 hours, or as little as 6-7 hours, but the maximum should not exceed 10 hours and the minimum should not be less than 5 hours, otherwise your body will not be able to take it.

Therefore, it is more important for you to design your sleep schedule according to your condition than to go to bed early and get up early in a blind and rough manner.
