Actually , In theory , There are no strict rules about when to go to bed ——

As long as you can get enough sleep , also The time of going to bed and getting up every day is regular , It doesn't count as staying up late .

however , Night owls, don't be in such a hurry , Here are two keywords ： law .

in other words , If you want 2 Take a nap 10 Click on it , Make sure you fall asleep at this point every day 、 Just get up .

But for the vast majority of the student party and the working party , In the morning 10 spot , I have already started a day's life .

Besides , People's biological clock has evolved over the years , It is closely related to light .

If the sun comes out to shine on your ass , You're still sleeping , It is easy to cause problems such as abnormal hormone levels .

Some netizens who stayed up late for a long time said , Already suffering from high blood pressure .

This is not alarmism , But there is a certain scientific basis .

The circadian rhythm of human body is mainly affected by light

A former information expert at the National Cancer Institute from the American Sleep Foundation Eric Suni, and Alex Dimitriu The doctor wrote an article describing the factors that affect the circadian rhythm and biological clock of the human body .

It's worth noting that ： Circadian rhythms are not equivalent to biological clocks .

Circadian rhythms refer to life activities with 24 There is a periodic change of about two hours .

The average rhythm of human circadian rhythms is slightly longer than 24 Hours , And have individual differences , Controlled by the body clock .

The different systems of the human body follow the circadian rhythm , Synchronized with the master clock in the brain .

This master clock , It exists in the superior nucleus of the hypothalamus （SCN）.

about SCN Come on , The strongest inducement signal is light .

Light can pass directly through retinal ganglion cells （ipRGCs） To hypothalamus , Project to SCN.

At different times of the day ,SCN Clock genes in the body send out different signals to regulate the activities of the whole body .

Day , Light signals the master clock , Generate awareness , Help people stay awake and active .

When night falls , When the light is weak , The master clock sends a signal to start production melatonin —— A hormone that promotes sleep .

SCN The output signal of can affect many tissues of the human body , Including liver 、 Adrenal gland and pineal gland, etc .

There are studies that show that ,SCN The output signal is regulated by blood glucose and cholesterol , Affect metabolism and weight .

Besides , Circadian rhythms can also affect mental health , Circadian rhythm disorder may lead to mental diseases such as depression and manic depression .

And studies have shown that , Circadian rhythms are important for the immune system and for cancer prevention DNA The repair process has an important impact .

Sum up , Although I go to bed late and get up late Theoretically Not to mention staying up late , But it is difficult for social people to do ; The disadvantages of staying up late involve all aspects .

therefore , We should try our best at night 11 Wash before o'clock and lie flat ！

“ Early to bed and early to rise makes a man healthy,wealthy and wise. ” It still makes sense .
