Because the longer you sleep, the lazier you will be. When your brain processes the relaxation phase, you will feel listless and sleepy. A study by physiologists found that people breathe slowly during sleep and the carbon dioxide in their blood increases. If they sleep more than ten hours a day, the carbon dioxide accumulated in the blood will become an anesthetic in the human body, which makes people feel groggy, which is why people want to sleep more and more. At the same time, long-term sleep will also reduce the excitability of people's cerebral cortex because of depression for too long, leading to slow response and memory decline. In addition, due to the decrease of basal metabolism during sleep, excess calories will be converted into fat and accumulated in the body, making people fat. When people sleep, their breathing will slow down and the accumulation of carbon dioxide in their blood will increase. If they sleep more than ten hours a day, the carbon dioxide accumulated in the blood will become an anesthetic in the human body, making people feel groggy. This is why people sleep more and more. At the same time, long-term sleep will also reduce the excitability of people's cerebral cortex because of depression for too long, leading to slow response and memory decline.
It can also prolong life. But sleeping too much can cause "premature death". Even the once-recognized "ideal sleep time of 8 hours a day" will lead to shortened life expectancy. People who sleep more than 8 hours and less than 4 hours a day will have their life expectancy shortened to varying degrees.
From a health point of view, there is absolutely no need to sleep too much. For a long time, people who think that sleeping too much is good for their health are actually misled, so sleeping too much is not good. It's ok to sleep in on weekends, but if you sleep too long, it will have a bad influence on your health. Proper sleep can restore physical strength and eliminate fatigue, but if you sleep too much, you will not eliminate fatigue, but will affect your health.
Sleep generally refers to human sleep, which is an indispensable physiological phenomenon of human beings. In a person's life, sleep accounts for nearly13 of the time, and the quality of sleep is closely related to human health, which shows how important sleep is to everyone. In a sense, the quality of sleep determines the quality of life.
