importance of sleep
Sleep, like diet and exercise, has an important impact on our physical and mental health and development. After a day of work and study, sleep can give your tired body adequate rest, help your body "recharge", and give you the mental and physical strength to continue studying the next day.
The important role of sleep:
1. Eliminate fatigue and restore physical strength
2. Enhance immunity
3. Promote development
4. Regulation of emotions
5. "Detoxification" function: remove metabolic waste
6. Enhance memory
7. Maintain heart and overall health
How much sleep is enough?
The sleep time required by everyone is different, but based on the sleep situation of most people, the International Sleep Foundation has made the following recommendations:
0-3 months: 14-17 hours
4-11 months: 12-15 hours
1-2 years old: 11-14 hours
3-5 years old: 10-13 hours
6-13 years old: 9-11 hours
14-17 years old: 8-10 hours
18-25 years old: 7-9 hours
26-64 years old: 7-9 hours
64 years or older: 7-8 hours
What is a good sleep?
In addition to sleep time, sleep quality is another important factor in quality sleep.
Getting enough sleep does not mean having good sleep quality. Sleep quality refers to the quality of our sleep, which is as important as the duration of sleep. Many people sleep more than 8 hours but often feel tired. This is most likely due to poor sleep quality. The sleep stages of these people are mostly light sleep and cannot enter deep sleep. When I wake up in the morning, I feel as if I haven't slept soundly throughout the night, making it difficult for my body to rest and often feeling sluggish. Therefore, in addition to maintaining enough time, you need to pay more attention to the quality of your sleep. Browse Sleep Tips to learn effective strategies for a good night's sleep.
