When you press the snooze function, the sleep cycle of the brain will be chaotic.
Many people think that turning on the snooze alarm button is only related to whether you go out on time, but in fact, if you go back to sleep again, your body will enter the state of sleep cycle again, ready to release hormones and trigger deep sleep. If you are woken up by the snooze alarm clock again, it will interrupt the sleep cycle and make your body and brain not know whether to sleep or wake up. Lead to lack of sleep, poor sleep, sudden wake-up, drowsy in the morning, slow response, bad temper, and slow work as if you haven't turned it on yet? This is called sleep inertia or sleep inertia.
What is sleep inertia?
Being slow after sleep means waking up in the morning feeling tired, groggy, unresponsive and having a reduced ability to solve problems, just like feeling after drinking four glasses of beer. Blood contains about 0.08% alcohol concentration, which usually lasts about 15~30 minutes. The study also pointed out that in the first three minutes after waking up, people's judgment is only 565,438+0%, which is a transitional period when the body and brain are awake. If the doze function is turned on, the feeling of boredom after sleep will be prolonged. However, the sleep research in the Department of Neurology, Fernberger Medical College, Northwest University pointed out that after sleeping in a cage, within 7 minutes after waking up, the heartbeat and blood pressure will increase, and the autonomic nerves will enter a state of preparation. On the contrary, it is not conducive to physical recovery and causes chronic fatigue.
Sleepiness can also cause health problems. Paying more sleep debt every day can cure the problem.
In addition to using the nap function, people will be more tired, and sleeping for more than 9 hours will also cause health problems. Related studies have pointed out that long-term sleep will worsen memory and increase the risk of dementia. Sleeping for more than 8 hours has also been confirmed to increase the risk of diabetes by 14%.
So what if you really don't get enough sleep on weekdays and can only choose to pay off your sleep debt on Saturday? Experts suggest that the best way to pay off the sleep debt is to spend 1~2 hours of sleep a few nights a week or a month, that is, to go to bed 1~2 hours in advance, so as to make up for the sleep healthily.
