Night falls and the stars are dotted, but for many people, it doesn't mean peace, but anxiety and distress. They lie in bed with their eyes shut tightly, but their thoughts are like wild horses out of control, hard to stop. The body is exhausted, but the mind is unusually clear, as if countless things are echoing in the mind, making it difficult to sleep.

"Did you drink too much coffee today?" , "There's a bunch of work to do tomorrow, what should I do?", "I don't think I've played with my cell phone enough, let's swipe it for a little while longer." These voices echo in the mind, making it impossible to meditate. So they began to try all kinds of methods to solve this problem: take melatonin, take a nap, makeup sleep on the weekend ...... But do these methods work? Or are these methods just a short-lived relief that doesn't get to the root of the problem?

At the same time, another question is troubling many people: does going to bed late and waking up late count as staying up late? Some people believe that as long as the sleep time is enough, sleeping late and waking up late is not a problem; while some people believe that no matter how long the sleep time, sleeping late and waking up late will cause damage to the body. So which is more scientific? To answer these questions, we consulted some experts in the field of sleep, and for those of you who want to know the answer, you can continue reading below.

Many people have had the experience of being physically exhausted, but as soon as they lie down on the bed, their brain is like a wild horse out of control, and it is difficult to stop. Doctors explain that this is because our body and brain are sometimes not synchronized. The body may be tired, but the brain may still be running at high speed and not relaxing. Why is the brain so active? It may be related to our activities during the day and our habits before going to bed. For example, the brain has been running at high speed during the day because of intense work and study; and at night, it has eaten too much, or has been playing with cell phones, computers and other electronic devices, all of which may make it difficult for the brain to relax. In addition, some people start to be anxious as soon as they lie in bed, "Why can't I sleep?" This anxiety, on the contrary, makes the brain more active and makes it harder to fall asleep.

So, if you are also experiencing such problems, try these methods: give yourself some time to let your brain gradually relax; adjust your habits to avoid overstimulation and bad bedtime habits; and try to keep your brain calm and not overthink when you are lying in bed.

On the question of whether going to bed late and getting up late is considered staying up late, in fact, not most people think that more than a certain time, even if it is staying up late. Whether or not you stay up late depends on your biological clock and the quality of your sleep. If your biological clock is used to going to bed late and waking up late, and you can ensure adequate sleep time and quality, then this is not considered to be staying up late. However, if you suddenly change your routine, or if you go to bed late and wake up late but have poor sleep quality, then this could be damaging to your body. If you like to play with your cell phone, put it down, and choose something calming in the hour before you go to sleep, rather than letting your brain continue to receive stimulation. You can also try to change a set of pillows or sheets that you feel comfortable with, adjust the brightness of the house, and enter the dreamland properly after sufficient preparation, which is believed to improve the quality of your sleep.
