Scientific data reports show that human beings spend one-third of their lives sleeping. Obviously,sleep is very important to our health. The following is the best sleep time for each age group, I hope it will be helpful to you.

According to scientific research, in fact, the best sleep time can be approximately calculated according to a formula: y=21-6x^0.3+x/10 (x means age, y means the best sleep time). In general, the optimal sleep time for humans decreases as people aged.

As the picture shows, the optimal sleep time for a newborn is 20-22 hours a day. A 1-year-old baby is best to sleep 15 hours a day.

For teenagers aged 8-12, 10 hours of sleep is necessary. However, maybe this is somewhat difficult. Because some schools assign too much homework to children so that children even need to do homework until 11 o'clock in the middle of the night or later, which is extremely detrimental for teenagers.

Adults who are 18-59 should sleep 7-8 hours per day. Office workers may be busy with work, but don't forget to take care of your body. In China, there is a proverb called "the body is the capital of revolution". Only with a healthy body can we have the “capital” to pursue our dreams. Secondly, if the sleep time is insufficient, it will also affect our working efficiency the next day. The emergence of smart phones has made us waste a lot of time virtually, so some experts suggest not to bring mobile phones into the bedroom to ensure that we can fall asleep in time.

For the elderly aged 60-70, it is necessary to sleep 5.5-7 hours a day.

What needs to be explained is that even if we sometimes cannot guarantee enough time to sleep due to various reasons, please do not feel anxious because of this.
