Core Tip: March 21 is World Sleep Day. This year's theme in China is "Focus on sleep and caring for the heart." Recently, a "2013 World Sleep Day Survey" was conducted. The results showed that 40% of the netizens often stayed up late, 26.67% of the respondents often suffered from insomnia, and 73.33% were "sleeping early and getting up early".
"Insomnia is defined as the inability to fall asleep, to stay asleep, or to be in a non-restorative state of sleep. Recent population studies have shown that insomnia can lead to a significant increase in the risk of diabetes, hypertension, coronary heart disease, heart failure, and stroke, all due to death. The risk is also significantly increased; death and sleep time have a U-shaped curve relationship, the optimal sleep time is 7-8 hours, the risk of death is the lowest in this period. The mechanism may be related to insomnia leading to abnormal glucose metabolism, endocrine abnormalities, sympathetic nerve activity Elevation is related to the inflammatory state of the body." Ma Changsheng, director of the Department of Cardiology, Beijing Anzhen Hospital, said.
Guaranteed 6-8 hours of sleep The most healthy Professor Zhang Xiangmin, director of the Sleep Disorders Clinic of the Sixth Affiliated Hospital of Sun Yat-Sen University, said that for adults, a 6-8 hour break is usually sufficient. Too little or too much sleep time is not good for heart health. Studies have shown that compared with 6-8 hours of sleep per night, people who sleep less than 6 hours are twice as likely to have a stroke or heart attack, and the risk of congestive heart failure increases. Similarly, sleep more than 8 hours. People are twice as likely to have angina and the risk of coronary artery disease. Young people are advised to develop good sleep habits of 6-8 hours a day.
Sleeping at night is awakened by an alarm clock and hurts "heart"
According to the survey, 61.54% of the respondents were awake by the alarm clock in the morning. In this regard, Zhang Xiangmin said that when sleeping late in the morning, when he is awakened by an alarm clock, he is often in deep sleep. During deep sleep, his blood pressure will decrease, his heart rate will slow down, his muscles will relax, his metabolism will slow down, and he will not experience enough light sleep time buffer. Suddenly, I was woken up by the alarm clock and got up immediately. The blood pressure and heart rate were instantly converted, and the blood supply to the brain was insufficient. Cardiovascular patients may become ill.
If a person's heart rate during deep sleep is 60 beats per minute, the heart rate after a sudden wake up is likely to become 100 beats per minute, which will cause the heart to "injury" in the long run. Zhang Xiangmin said that when the body is in a shallow sleep, being awakened by an alarm clock has no effect on the body. The sound of the alarm should be mild music. When you wake up, you can sit in the bed for half a minute, then sit down on the bed for half a minute, then go down to the ground to facilitate full waking.
