I believe many people have heard this sentence: Napoleon only slept 3 hours a day. Although we have no way of knowing whether this statement is fact or legend, we can formulate superb strategic plans, use tactics freely, and win many times. Even if we only sleep 3 hours a day, we still conform to the image of a famous general. In addition to Napoleon, it is said that the inventor Edison believed that sleeping was a waste of time, so his average sleep time was only 4-5 hours a day.
Among modern celebrities, there are also many who are known for their short sleep duration. For example, Masayoshi Son, chairman of Softbank Leisure Resources *** Group, sleeps 3-4 hours a day, and former US President Barack Obama sleeps 6 hours a day. The latter time is not particularly short, and may be close to the standard sleep time in busy people.
In addition to them, celebrities with short sleep time also include Akashi’s saury and the author of the manga “One Piece” Eiichiro Oda. It is said that they sleep only about 3 hours a day. Not just celebrities. Recently, more and more business people will get up around 4 or 5 in the morning to participate in study sessions, reading sessions or learn foreign languages.
So: “How many hours of adequate sleep do you need to be healthy?” kind of point of view. We often hear the cliché that for humans, 8 hours of sleep must be required. It is also said that human sleep takes 90 minutes as a cycle, so the most suitable sleep duration is a multiple of 90 minutes, that is, 7.5 hours. In modern society, there are many people suffering from sleep disturbance. If “having an ideal sleep” is the standard, then almost all modern people have such troubles.
“Intensive sleep” can make a big difference in sleep quality. The so-called “concentrated sleep” refers to the non-REM sleep that reaches the deepest level within 30 minutes after falling asleep and maintains a deep sleep state for a certain period of time. In simpler terms, fall into deep sleep immediately after bed rest, and stay in deep sleep. So is the way to get enough deep sleep in less time. It usually takes about 90 minutes after falling asleep to reach deep sleep. But “focused sleep” allows us to reach deep sleep three times faster, that is, within 30 minutes of falling asleep. Compared with long-term light sleep, short-term deep sleep can make the body more relaxed, the brain runs more smoothly, and work performance is better.
Modern life is full of various factors that hinder deep sleep. Whether No matter how long you sleep, light sleep will not help us fight fatigue.
Chronic sleep deprivation can have adverse effects on physical and mental health: increasing the risk of depression, cancer, Alzheimer’s disease and other diseases.
The improvement of sleep quality can improve physical and mental state and work performance, which has great significance and affects our lives.
Improving sleep can not only improve concentration and work efficiency, but also create a healthy mental state, enabling you to face work and life with a positive attitude, and even make you Experience the joy of life and make your life colorful.
