Is it good to sleep too much, and is it better to sleep as much as possible?

Sleeping too long not only can't eliminate fatigue, but also brings a lot of harm to the human body.

1.Weakness. When a person is active, the heart beats faster, the contractility of the heart muscle increases, and the cardiac output increases.

When the human body is resting, the heart is at rest, and the heartbeat, contractility, and blood output decrease. If you sleep for a long time, it will destroy the rhythm of rest and exercise of the heart, and the heart will rest again and again, and eventually the heart will be weakened by contraction, and the heart will not beat after a little activity.

1. Panic and fatigue, so I have to lie down again to form a vicious circle, resulting in weakness.

2.Susceptibility to respiratory diseases. The air in the bedroom is the dirtiest in the morning, even if the windows are closed, there is still some air not circulated, and the unclean air contains a lot of bacteria, viruses, carbon dioxide and dust, which has an impact on the respiratory tract's ability to resist diseases.

As a result, those who snooze behind closed doors often suffer from colds, coughs, and sore throats.

3.Limb fatigue and weakness. After a night's rest, muscles and joints will become relaxed, and immediate activity after waking up can increase muscle tension, increase the blood of muscles, make bones and muscle tissue in a state of repair, and eliminate metabolites accumulated in muscles at night, which is conducive to muscle tissue recovery and exercise.

People who sleep lazily miss the opportunity to move due to muscle tissue, and feel weak legs, lumbosacral discomfort, and weakness after waking up.

4.Affects digestive function. Lazy people cannot eat on time, and the gastrointestinal tract has hungry peristalsis, which disrupts the secretion of gastric juice and affects digestive function.

5.Interferes with nervous system function. People who sleep lazy sleep have a long-term excited sleep center, while other nerve centers will be relatively slow to resume their functions due to inhibition for too long, so they will feel groggy and listless.

About 8 hours of sleep a day is enough for adults. If you sleep too much, the sleepier you will be, and the more you sleep, the more you will pinch.

No. A good quality sleep doesn't mean you sleep as long as possible. In fact, depending on the physiological needs of the individual, the optimal sleep time can be between 7 and 9 hours.

Sleep quality is more important, which means sleeping in a quiet, comfortable environment that is free from noise and light disturbances. Also, follow a regular sleep and wake up time on a regular basis to help maintain the quality and health of your sleep.

There are many scientific studies that show that sleep duration and sleep quality have an important impact on human health. For example, studies have shown that sleeping less than 7 hours in a row may lead to cognitive impairment, difficulty concentrating, memory loss, mood swings, and physical health problems such as high blood pressure and diabetes.

On the other hand, too much sleep is also bad for your health, as it can lead to excessive relaxation, slowing down metabolism, weight gain, and the risk of chronic disease.

Therefore, sleep duration and sleep quality are both very important and are key factors in maintaining good health.

The answer is no. Traditional Chinese medicine believes that lying down for a long time hurts qi, that is, too much sleep dissipates the essence and energy, and makes the yang energy and essence infiltrate and slacken. Modern research has proved that excessive sleep and bed rest can cause neurological depression of cerebral cortex cells, resulting in cerebral hypoxia.

Therefore, sleeping more is not good for your health.

So, how long is the right amount of sleep? The amount of sleep you spend varies from person to person, and there is no absolute value. It is generally accepted that 8 hours of sleep is normal.

In a questionnaire survey of 1 million people, it was found that 80% of adults slept within 7 to 9 hours of Cong Jian every day. Another survey of 800 people found that the average sleep time was hours. In addition, the so-called short sleepers who slept for 4 to 5 hours and the long sleepers who slept for 10 to 11 hours accounted for only 1% of 2%, while the ultra-short sleepers who slept less than 4 hours and the ultra-long sleepers who slept more than 11 hours accounted for less than 1%.

In short, the duration of sleep varies from person to person, and the average person generally does it within the range of 6 to 9 hours.
