1, sleep time. Sleeping less than 4.5 hours and more than 9 hours will increase the incidence of diseases. Even if you stay up late, you should ensure more than 4.5 hours of sleep. In foreign countries, all workers who stay up late will pay extra compensation for staying up late, which shows how harmful it is to stay up late! If you sleep for more than 9 hours, you will often feel digestive problems, headache and dizziness, and your immunity will decline. So sleeping too much and sleeping too little will have an impact on your health.
2. Sleep quality. Some people often say that they still feel extremely tired after sleeping for seven hours. Why? Because of the quality of sleep, it's like I slept peacefully for seven hours, and you often dream and wake up during these seven hours of sleep. Although I finally got enough sleep, the quality of sleep is definitely completely different. People with poor sleep quality can reduce the intake of spicy food in their diet, don't drink too much water before going to bed, and strengthen exercise to improve sleep quality. Of course, you can also drink a cup of healthy tea before going to bed, which has the effect of calming the nerves and helping sleep. "
