Why do you wake up at 2 or 3 o'clock in the night?

Sleep is very important to us, and everyone needs to get eight hours of sleep a day so that we have enough energy to study and work the next day. If we often lack sleep, it will have a serious impact on our health. Some people may lack sleep due to insomnia, not just difficulty falling asleep, but often waking up in the middle of the night. So what is the reason for waking up at two or three o'clock in the night?

Sleep is extremely important for brain health. Minors generally need more than 8 hours of sleep, and the quality of sleep must be guaranteed. If the sleep time is insufficient or the quality is poor, it will have adverse effects on the brain. The brain fatigue will be difficult to recover, and it may seriously affect the brain's function. If teenagers do not get enough sleep or have poor sleep quality, they should increase their sleep time appropriately, such as taking a short nap in the summer, and try to improve their sleep conditions.

Causes

According to general belief, sleep is the main way to eliminate brain fatigue. If you lack sleep for a long time or your sleep quality is too poor, it will seriously affect the function of your brain, and even a very smart person will become confused. Many young students suffer from diseases such as neurasthenia, which are often caused by severe lack of sleep.

Get enough sleep

1. One of our important points is that sleep is essential. Many books say that adults generally only need 7-8 hours of sleep a day. But recently, Dr. James Maas, an American psychology professor, pointed out that 6-7 hours of sleep at night is not enough for a person. The results of his sleep research showed that only 8 hours of sleep can enable the human body to function at its peak. So what is "appropriate"? The main standard is "recovery of mental and physical strength."

Human sleep is divided into two phases: slow eye movement sleep and rapid eye movement sleep. Concentrated REM sleep, which is involved in memory storage, maintaining organization, organizing information, and new learning and performance, all occurs in the last stage of REM sleep. REM sleep usually occurs in the latter part of an 8-hour sleep period and can last about 90 minutes. Although we may not realize it, most of us are not getting enough sleep, which not only reduces our quality of life but may also cause disease.

To compensate for this widespread sleep deprivation, Dr. Maas advocates for “naps.” This type of nap refers to a 20-minute nap after waking up from formal sleep every day. Its effect is much better than going to bed early at night.

We would like to emphasize that although the burden on primary and secondary school students has been reduced, they are still not relaxed due to the pressure of various exams, and many of them are clearly not getting enough sleep. Compared with the past, it is actually loose in appearance but tight in reality. This is actually not worth the cost for both society and the family. We believe that only by sleeping well can we study well. A good night's sleep will not hinder your future: sleep time must be guaranteed!
