With the emergence of aging, more and more sleep-related complaints and sleep disorders have begun to appear. Among the elderly living in the community, about 50% of them complain of various forms of sleep difficulties. Compared with young people, the elderly need to take longer to fall asleep, have lower sleep efficiency, wake up more often at night, wake up earlier than expected, and need to nap more during the day. Long-term sleep disorders can lead to decreased immunity, decreased thinking and memory, and lack of energy during the day, which seriously affects life and health. Therefore, we should pay more attention to the insomnia of the elderly, improve awareness of elderly sleep disorders, strengthen assessment and active treatment, and strengthen health care.

Adolescents are in the “storm” stage of sleep development. The gradual delay of internal biological rhythms, coupled with external social and environmental requirements, make the phenomenon of insufficient sleep more prominent. Chronic insomnia and delayed sleep phase disorder (DSWPD) are common adolescent sleep disorders. This article will focus on the causes, symptoms, evaluation and diagnosis, and treatment methods of adolescent insomnia and delayed sleep phase disorder, hoping to provide a reference for pediatric clinical practice, improve the clinical diagnosis and treatment capabilities of professionals, and promote the sleep health of adolescents. Sleep time accounts for about one-third of a person’s daily life. The importance of sleep to children and adolescents is not simply reflected in the high proportion of sleep time. More and more studies

It is well known that lack of sleep initially manifests itself as fatigue, weakness, irritability, and difficulty concentrating. A few people who experience chronic sleep deprivation may even experience disorientation, paranoia, and hallucinations. To date, several animal studies have shown that chronic sleep deprivation is fatal, and that not sleeping at all leads to inevitable premature death. However, decades after the academic community began studying sleep deprivation, a core question about this phenomenon has not been resolved: Why do animals die without sleep? Now, neuroscientists at Harvard Medical School, HMS, have discovered an unexpected causal relationship between lack of sleep and premature death. In sleep deprivation studies of fruit flies, researchers found that they always observed a large accumulation of reactive oxygen species (ROS) in

With the rapid development of modern society, material life is becoming more and more abundant, but sleep seems to have become a more and more luxurious thing. How can we sleep well? I believe many friends will say this: “Sleep for 8 hours a day.” Is the popular “8-hour sleep theory” really scientific? In fact, there is no authoritative research in the world that can prove that people must sleep for 8 hours. A study published in Current Biology shows that in a study of more than 2 million people by the American Cancer Society, data showed that the vast majority of people sleep an average of 6.5 to 7.5 hours a night. In addition to children whose brains are still developing and need more

1 About brain waves When the brain is in a sleeping state, more nerve cells start working at the same time, just like many feet stepping together at the same beat. These nerve cells discharge at the same time, thus forming slower and stronger brain waves. 2 About deep sleep After insufficient sleep or strenuous exercise, the deep sleep period will be significantly prolonged. If you are awakened in deep sleep, you will have several minutes of reaction time and will feel uncomfortable. Infants and young children are almost impossible to wake up in deep sleep. Infants’ deep sleep is deeper than adults, and their light sleep is shallower than adults. This is also the root cause of many problems. For example, night terrors are

What is a sleep cycle? Sleep cycle refers to the existence of a biological rhythm in sleep. The International Sleep Medicine Association divides sleep into five stages, and each stage is experienced in about 90-100 minutes. People’s normal sleep structure cycle is divided into two phases: non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM). NREM and REM alternate, and one alternation is called a sleep cycle. The two cycles go back and forth, and there are usually 4-5 sleep cycles every night, each cycle is 90-100 minutes. The sleep time of humans at different ages is different. Babies need 20 to 24 hours of sleep, toddlers need 9 to 12 hours, schoolchildren need 9 to 10 hours, adults need 7 to 9
