However, some people find that they still feel sleepy and tired even after sleeping for 8 hours. Why? The answer may not be what many people think.
Sleeping is a complicated process. If you don't sleep enough, sleep too much and sleep too late, it will have a negative impact on your body. When is the best sleep time? Read on about the truth about sleep.
Getting up early is only relative. People who get up early have a healthy sleep. If they go to bed early at night and don't sleep late in the morning, it is normal to get up early.
Healthy sleep needs to conform to our body's physiological cycle. Generally, I start to sleep at about 10 at night and wake up naturally in the morning, which is in line with the human sleep cycle.
So getting up early is not necessarily healthy. Besides your biological clock, there may be insomnia or other sleep problems.
Many people may say that the best time is 8 hours, but it is not. For most people, this time is an average time For people who sleep for a long time and sleep for a short time, this time is not applicable.
Some people don't sleep much, but they are in good spirits. Some people need to sleep for a long time to eliminate fatigue. A study of more than 460,000 people in the Journal of the American Heart Association found that people who sleep for 6 or 9 hours have a higher risk of heart disease.
So people who sleep 7-8 hours a day will feel healthier, but people of different ages have different sleep times, and everyone should decide according to their own situation.
Over 65 years old: the best sleep time is 6~7 hours.
45~65 years old: The best sleep time is 7~8 hours.
18~25 years old: the best sleep time is 7~9 hours.
14~ 17 years old: the best sleep time is 8~ 10 hour.
6~ 13 years old: the best sleep time is 9~ 1 1 hour.
3~5 years old: the best sleep time is 10~ 13 hours.
1~2 years old: the best sleep time is 1 1~ 14 hours.
0~ 1 year: the best sleep time is 12~ 15 hours.
There are several kinds of sleep problems, one is that you can fall asleep after lying in bed for a long time, the other is that you wake up soon after falling asleep, or you feel very tired the next day.
This is a typical poor sleep quality, which is caused by many reasons, such as mental stress and exercise before going to bed. Poor sleep quality will make the body not get enough rest, and the brain nerves are in a tight state.
So pay attention to the quality of sleep. What should we do to get a good sleep? First of all, don't play with your mobile phone before going to bed. Many people will play mobile phones for a while before going to bed, which will make people excited and lead to a decline in sleep quality.
Secondly, don't eat for 20 to 30 minutes before going to bed, and then you will soon feel sleepy when you sit in bed. This can improve the quality of sleep and will not be lacking after waking up.
Why is it always difficult to fall asleep when it is time to rest?
Difficulties in falling asleep may be related to emotions. Many young people have mental health problems, such as depression, which will affect the quality of sleep.
Excessive anxiety can also affect the quality of sleep. If the pressure is relatively high at ordinary times, it is easy to think too much at night and have anxiety.
If you want to improve the quality of sleep, you should adjust your mood, so that you can fall asleep quickly. You can also soak your feet with hot water before going to bed. Don't think too much.
There is no fixed standard for sleeping. You can sleep as comfortably as you want. If you haven't tried to sleep naked, you can also try to sleep naked, which will make you sleep better.
