Office workers basically sleep late every weekend. What are the dangers of sleeping late? How can we prevent it?
risk 1: Stroke and diabetes
After investigating more than 90000 women aged 50-79 for seven and a half years, researchers in the United States found that those who slept more than 9 hours a day had a 70% higher risk of stroke than those who slept 7 hours. Sleep time was an independent factor that increased the risk of stroke.
Experts from Nanjing Brain Hospital said that the blood viscosity of the elderly is relatively high. If they sleep for too long, it will lead to an increase in blood viscosity, which is easy to induce stroke and other cerebrovascular diseases.
According to relevant experts, there is also a study that shows that sleeping too long may also induce diabetes. The survey found that people who sleep 7-8 hours a day are the healthiest.
If you sleep less than 6 hours, the risk of diabetes will increase about twice; If you sleep more than 8 hours, your risk of diabetes will more than triple.
A survey shows that sleeping less than 6 hours a day will harm one’s health. At the same time, sleeping more than 9 hours can also be harmful to health. In the investigation of sleep time, the sleep time with the lowest mortality rate was about 7 hours.
People who sleep less than 4 hours or more than 10 hours a day on average, regardless of whether they are men or women, have a high mortality rate.
risk 2: respiratory, cardiac and digestive diseases
Xiao Li is a teacher in a school. He likes to sleep in. He often sleeps for more than 10 hours in summer vacation. He found that his health was still poor, and he often caught colds. The doctor helped him to analyze and think that his frequent colds may be related to his love of sleeping in.
The air in the bedroom is the dirtiest in the morning. Even with the windows open, some of the air is still not circulated. The dirty air contains a lot of bacteria, viruses, carbon dioxide and dust, which has an impact on the disease resistance of the respiratory tract.
For those who sleep behind closed doors for a long time, they usually exercise less. Coupled with the dirty air in the bedroom, they are prone to frequent cold, cough and other symptoms.
When people are active, their heart beats faster, their cardiac contractility is strengthened, and their cardiac output is increased. When people rest, their hearts are at rest, and their heartbeat, contractility and blood output decrease. If you sleep too much, it will destroy the law of heart rest and exercise. The heart will rest again and again, and eventually the heart will contract weakly. A little activity will lead to inconsistent heartbeat, panic and fatigue.
risk 3: the more you sleep, the lazier you become, and the lower your intelligence.
“I sleep 10 hours a night. Why am I still listless during the day?” Xiao Chen, who works in a company, simply can’t figure it out. In the past, he often complained that he slept too little, so that his head became dizzy. But I have increased my sleep time every day, but I am still not energetic. I react slowly at work, and I have been scolded many times by my boss.
Most people will think that to eliminate fatigue, we should sleep more. In fact, the idea of increasing sleep time to achieve health is completely wrong. People who sleep too long will become lazy, weak, and even their intelligence will decline.
After a night’s rest, muscles and joints will become relaxed. Moving immediately after waking up can increase muscle tension and blood supply to muscles, so that bones and muscle tissues are in a repair state. At the same time, metabolic products accumulated in muscles at night can be eliminated, which is conducive to muscle tissue’s recovery from exercise.
People who often sleep late miss opportunities for activities because of muscle tissue, and feel weak legs, lumbosacral discomfort and weakness after getting up.
The sleep center of people who sleep late is in an excited state for a long time, while other nerve centers will be inhibited for too long, and the function of recovering activities will become relatively slow, so they will feel drowsy, listless, and even have intellectual decline all day long.
