To keep us healthy and beautiful, we always say don’t stay up late, but do you know when to sleep is to stay up late? Our Lash will help you to find an answer today.
In fact, it's not very scientific to judge whether you stay up late by the time you fall asleep.
Scientific studies have found that everyone has their own circadian rhythms; it is determined by the PER3 gene in the body. Some people are early birds (go to bed early and wake up early), while others are natural evening types (go to bed late and wake up late).
Forcing early sleepers to go to bed earlier was just as uncomfortable for them as forcing early birds to stay up late. After all, people who sleep late at night are more alert and productive than those who work or study during the day. So, even going to bed in the wee hours of the morning and getting up in the middle of the day doesn't count as a late night if you make sure you sleep regularly and get enough sleep. When it comes to sleep duration, the well-known "eight hours" has little scientific backing -- some people feel refreshed after six hours, while others need nine hours or more. But with rare exceptions, the circadian rhythms of ordinary people are rarely unaffected by light, temperature, and social rhythms. Imagine you go to bed at 6 am and wake up at 12 am every day. You work regularly and get plenty of sleep, but your rest time is hard not to be affected by busy neighbors, plenty of light and noisy cities. Sleep time and regularity are guaranteed, but the quality of rest will be greatly reduced. Disconnect from your normal life can also affect how you eat, exercise, etc.
How is staying up late hurting you?
Although it is often said that an occasional late night is nothing but catching up on sleep the next day is enough; It's ok to sleep less on weekdays, because it's ok to come back on weekends. But every time after staying up late, the body's discomfort is real: yawning, dizziness, chest tightness, in short, the whole person is not good.

Not to mention staying up late for years and years will lead to disruption of the human body's sleep rhythm, which will make the body pay a lot of "costs" over time.

4. Staying up late can also increase the risk of cancer and sudden death.
Studies have suggested that disrupted circadian rhythms may increase the risk of cancer. In addition to clocks at the macro level, our organs and even our cells have their own clocks. Constantly disrupting their body clocks raises the risk of breast, colon, ovarian and prostate cancer, among other diseases.
What about the dreaded "sudden death" that's been in the news so much lately? Is it also related to staying up late? Scientists have found that heart cells have their own circadian rhythms, adjusting and maintaining the right heart rate to match changes in the body. Staying up late disrupts this rhythm, which in turn increases the risk of arrhythmias and other problems. For healthy people, although not sudden death, but still may cause heart discomfort; And for those who already have cardiovascular disease, extra care should be taken. The disturbance of circadian rhythm can affect the number of immune cells and reduce the immune ability; Also, it affects your mental health and increases your risk of depression.
Therefore, people who often stay up late, whether physically or mentally, externally or internally, have greater pressure and higher risk than those who don't.
