Sleep longer is not always better, and sleeping too long is not good for your body. 7-8 hours of sleep a day is appropriate.

I don't think longer is better, just get 8 hours of sleep a day.

This is certainly not the case, and scientific studies have shown that 8 hours of sleep a day is best for adults.

In recent years, some scholars have questioned the health effects of 8 hours of sleep, arguing that sleep quality is more important than sleep duration. So what kind of sleep is healthy? Let's take a closer look.

Sleep length is not an absolute standard.

Normally, we think that adults need 8 hours of sleep per night to stay healthy. But this is not an absolute standard, as everyone has different sleep needs and may need more or less sleep. Studies have shown that there may be more than 20% difference in sleep needs between individuals, and even the same person will be affected by factors such as age, gender, health status, and lifestyle.

Sleep quality is more important.

Sleep quality refers to the depth and continuity of sleep. Good sleep quality can make people feel energetic and keep their body healthy, but vice versa, it can lead to fatigue, headaches, and difficulty concentrating. Some studies have shown that sleep quality is more important than sleep duration.

It is recommended that everyone create a quiet, comfortable and dark environment before sleeping, try to avoid all kinds of noise and interference, and ensure the continuity and depth of sleep.

The relationship between sleep time and health.

While standards for sleep duration may vary from person to person, there are studies that suggest that chronic sleep deprivation or excess may increase many health risks. Long-term sleep deprivation may lead to problems such as obesity, diabetes, cardiovascular disease, weakened immune function, depression, etc. Prolonged sleep may increase the risk of cognitive impairment, cardiovascular disease, and mental health problems.

Conclusion. Overall, sleep quality is more important than sleep duration. Although everyone's sleep needs are different, we should do our best to ensure a balance between sleep time and sleep quality to maintain a healthy sleep habit.

6-10 hours of sleep a day is appropriate, and the exact time needs to vary from person to person.

Sleep is an indispensable physiological phenomenon of the human body, about 1 3 times in a person's life in the state of sleep, sleep quality and human health have a close relationship. Adequate and high-quality sleep helps to restore mental and physical strength, can relieve visual fatigue, prevent the occurrence of vision loss, and also help to enhance the body's immunity.

Because each person's sleeping habits and sleeping environment are different, there are individual differences in the amount of sleep time per day, and the daily sleep time of minors is usually controlled at about 8 to 10 hours; Young and middle-aged people usually sleep for 7 to 8 hours a day; The sleep time of the elderly will be relatively reduced, and the sleep time will also decrease, generally about 6 hours. Generally, if you wake up after sleep, if you feel comfortable, energetic, energetic, concentrated, etc., it means that the body and brain have obtained sufficient slag and rest in turn, then the sleep time is generally more appropriate.

How much sleep is appropriate for a person per day? The normal sleep time of a person is 6-8 hours a day, and generally speaking, the sleep time of a person is constantly decreasing with age. The sleep time of Lianshan is 18-20 hours in infancy, 10 hours in primary school, 8-9 hours in middle school, and 6-8 hours in adulthood.

It is generally recommended that 8 hours is better.

However, in general, the sleep time will be reduced after old age, and some elderly people can sleep for 5-6 hours. There is another criterion for judging whether the sleep time is enough, which is to see whether the mental state of the next day is good. If it does not affect the study and work, the mood in the self-shed is relatively happy, even if the sleep time is less than 6-8 hours, it is still normal.

There is no fixed time for this, and everyone's time is different. If you sleep for 7 hours and don't get sleepy, then you can sleep for 7 hours.

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.
