Research shows that people between 30 and 50 get the least sleep. How long did you sleep today?

Science Fiction Network, December 27 (Xu Mingyang) University College London and the University of Lyon in France recently published a study in the journal Nature Communications. The study found that globally, the sleep time of adults shows an early downward trend until the age of 33, then recovers again at the age of 53, and it is found that the closer to the equator, the less sleep people get.

Statistics show that people spend about one-third of their lives sleeping, and sleep quality has an important impact on human health. Sleeping too long or too short, or having abnormal movements during sleep, may all be caused by sleep disorders.

The researchers found more than 730,000 participants from 63 countries. They divided the participants' ages into three stages: early adulthood (19-33 years old), middle adulthood (34-53 years old) and late adulthood (over 54 years old). They designed many test tasks for the participants and asked them to report on their sleep conditions and other issues.

The study found that the average sleep time of participants was 7.01 hours per night, and women slept a few minutes more than men on average. Participants in early adulthood had the longest sleep time. After the age of 30, sleep time began to decline and gradually stabilized. At around the age of 50, sleep time began to increase again. The researchers believe that this change may be because people in middle adulthood have greater work and life pressures, and many families have children to take care of.

In addition, the researchers also found that sleep duration is also related to the region where the participants are located. The closer to the equator, the shorter the sleep duration.

Nowadays, many young people have the habit of staying up late for work or entertainment, but staying up late often may affect the body's metabolism, leading to constipation, obesity, slow reaction and other problems. Therefore, it is important to improve our sleep quality. Doing moderate exercise two hours after breakfast or before dinner; not eating too much before going to bed; choosing a suitable pillow; creating a dark and quiet sleeping environment, etc. are all conducive to improving sleep quality.
