The idea that “after staying up late to find a chance to catch up on sleep is all right” is wrong. Recently, Chinese fans stayed up late to watch the World Cup in successive tragedies, with Dalian’s 51-year-old player Li Mingqiang dying of a heart attack watching the West-Dutch battle, followed by the sudden death of a 25-year-old man in Suzhou, whose computer was still broadcasting the Chile-Australia group game when it was found. Professor Guo Ruoxiheng, a sleep expert, said that staying up late to watch football makes it easy for endocrine metabolism to become dysfunctional and for those with high blood pressure to trigger cardiovascular and cerebrovascular diseases, and that the lack of sleep from staying up late cannot be made up. The brain fatigue caused by one late night can not be eliminated even after several days of normal sleep. This phenomenon means that insomnia may have caused long-term damage to the brain. There is an experiment in which scientists studied mice. They developed a schedule for the mice that was similar to that of people working shifts: first let the mice take a nap, then wake them up and keep them awake for a short time; then let the mice sleep and wake them up again, this time keeping them awake for a long time. The scientists then examined the blue spot neurons in the mice’s brains. The blue spot is a cluster of neurons located in the brainstem whose function is related to the stress response. These neurons within the blue spot are thought to be related to alertness and cognitive function. The results showed that when the mice were mildly deprived of sleep, the nerve cells remained excited; however, when the mice were deprived of sleep for a long time, this response was turned off. Thus, after only a few days of “shift” rest, the nerve cells began to die faster. It was shown that prolonged sleep deprivation reduced the number of neurons in the mice’s brains by 25%. First of all, we have to say that sleep can only make up for the short-term, you did not sleep well yesterday, today to make up for sleep, to make up for it, but if you did not sleep well on Monday, the weekend to make up for sleep, it will not work. During the World Cup every day crazy watching football, sleep deprivation, should sleep when no sleep, want to make up through a one-time more sleep one day back, this idea is not scientific. The human biological clock is in a cycle of about 24 hours, and suddenly sleeping more than usual one day can mess up the biological clock and make people feel more fatigued when they try to resume their usual pattern. The biggest evil effect of catching up on sleep is to cause disruption of the biological clock. With more time for rest during a long vacation, some people will stay in bed even after they have had enough sleep, until they are dizzy and weak at noon, in a trance, with a lack of oxygen to the brain tissue and a heavy head. The body can adapt to a physiological rhythm of up to one hour delay, that is, a day to take time to sleep a little lazy is unlikely to have too much impact on the fatigue of a week of intense football watching. However, waking up two or more hours later can throw your body off balance, making it harder to sleep at night and more difficult to get up the next morning. The World Cup once every four years, fans naturally can not give up, stay up late to watch the game can not be avoided, but stay up late also to stay up out of the strategy. Strategic sleep spirit good most of the World Cup match days are 22:00 a game, 2:30 a game. The best time for the human body to rest is 23:00-3:00, this time to rest well, basically can feed the spirit of the day. Therefore, it is best not to watch both the 22:00 game and the 2:30 game. If the 2:30 game carries more weight, you can strategically drop which game is at 22:00, put on your alarm clock and go to sleep early. If you choose to watch the 2:30 game, you can get some shut-eye during the 15-minute break in the middle of the court, and you can also squint for a while after the game ends at around 4:30 am. As long as you ensure about 6 hours of sleep every day, you can resist the sleepiness for most of the day. It won’t take long for the body to adapt to the new biological clock, and it will become natural to watch the knockout games in the early hours of the morning every day. The actual food to make up for the lack of sleep will often need to eat more food, which is a self-compensating function of the body. During the World Cup stay up late watching football, fans can also use uninterrupted eating and drinking to distract sleepiness, in a way can reduce fatigue and replenish energy. The first choice should be the alkaline food that can eliminate heat and fire, such as watermelon, cantaloupe, tomatoes, cucumbers, etc.; secondly, we should pay attention to replenish energy and choose some high-protein foods, such as soy products, eggs, beef jerky, etc. Note: stay up late easy fire, potato chips, instant noodles and other fried food must be eaten less, cold beer, although painful, but drink more is also easy to cause fire, in short, drinking alcohol, barbecue, fried food in moderation, it is best not to eat.
