Why do people sleep more soundly when they are tired I slept well last night!

Researchers note that if you feel lethargic during the day, it's a sign that you're not getting enough sleep. If you fall asleep after lying down for 5 minutes, you may be severely sleep-deprived. Another sign of sleep deprivation is the occasional brief lethargy (paroxysmal coma, usually lasting only 1 to 10 seconds) or a short slurry during waking hours.

In many cases, people are unaware that they have experienced a brief lethargy. Nowadays, people generally have a habit of "over-draining", which can make people extremely sleep-deprived.

Many studies clearly show that lack of sleep is dangerous. Experiments with driving simulators or hand-eye coordination have found that people who lack sleep perform just as badly, if not worse, than those who are drunk. Lack of sleep also increases the harmful effects of alcohol, so drinking alcohol is more harmful to a tired person than a well-rested person.

Scientists. It was found that sleep can be divided into two completely different states: one is called fast-wave sleep.

Some people also refer to this sleep state as REM sleep. As the name suggests, the eyes move very quickly during sleep, and the brain is also very active, and people dream during this period.

The other state is called slow-wave sleep, which is the deepening of the first state, and the sleeper enters a deeper state of unconsciousness. Scientists have found that fast-wave sleep and slow-wave sleep work differently, and the two states also alternate during sleep.

The brain controls various parts of the human body, including the nervous system.

When you do physical or mental work in a day, it is the brain that plays a guiding role, allowing you to carry out all kinds of activities, when you work hard all day, when the night comes, your physical labor or mental work during the day, the amount of exercise information of the day, feedback to your brain commander, your brain commander will order your sleep nervous system, arrange the appropriate sleep time, and order other body parts to cooperate, do not disturb, so, when you are tired of the day, sleep is more soundBetter.

Because I am tired and need to rest.

Sleep should generally be maintained for 7 to 8 hours, but it is not necessary and should vary from person to person. Those who fall asleep quickly and sleep deeply, and generally have no dreams or few dreams, can fully recover their energy after 6 hours of sleep; People who fall asleep slowly and have many shallow sleepy eyes, often dream and nightmares, even if they sleep for 10 hours, they are still refreshed, and they should go through various ** to get effective sleep, but prolonging sleep time is harmful to the body. Since everyone has a different circadian rhythm, the arrangement of sleeping in the morning and evening should be different from person to person!

In fact, different circadian rhythms cause two conditions of sleep, namely "night owls" and "larks". Adapting to this circadian rhythm is good for work efficiency and quality of life, and vice versa, it is bad for health.

According to the medical theory of the motherland, it is advisable to go to bed late and get up early in spring and summer, and you need to sleep 5 to 7 hours a day; In autumn, it is advisable to go to bed early and get up early, and you need to sleep 7 to 8 hours a day; In winter, it is advisable to go to bed early and wake up late, and you need to sleep 8 to 9 hours a day. Conform to the laws of natural growth and collection.

Sunny, hot days with short sleep durations; Bad weather, such as rainy days, cooler winters, and long sleep hours. With the increase of altitude in the area, the sleep time decreased slightly; With the increase of the latitude of the shooting, the sleep time was slightly prolonged.

Feeling tired means that the body's energy is insufficient, and sleeping too much will also lead to insufficient energy for several reasons: 1If you sleep for too long, moisture will be generated inside the body, and the body needs to consume energy to transport moisture.

2.When you are inactive for a long time, the flow of qi and blood will become slow, and fresh oxygen cannot be delivered to all parts of the body in time, resulting in a lack of energy and fatigue in the body. 3.

If you don't get enough sleep for a long time, and then you sleep for a long time, the level of qi and blood will rise, and the body will begin to repair itself, which will consume energy, and it will also make people feel tired.

It's all stupid, and it's enough for a normal person to sleep 7 or 8 hours a day.
