It means not getting up after normal sleep time. Now, it mostly happens among working people and students. Because of the hard work and study, they often catch up on sleep on weekends, but overloaded sleep will cause sub-health of the body.
The harm of sleeping late
First, sleeping late will disrupt the physiological rhythm. Normal people's endocrine and the activities of various organs have a certain day and night law. This biological law regulates people's various physiological activities, making people energetic during the day and sleeping well at night. If you sleep late on holidays because of the law of life, it will disrupt the circadian rhythm in the body and make endocrine hormones abnormal. If this continues for a long time, you will be depressed and depressed.
Second, staying up late will affect the gastrointestinal function. Breakfast is usually around 7 o'clock. At this time, the food for dinner has been basically digested, and the gastrointestinal tract will contract due to hunger. People who love to sleep late would rather be hungry than get up early for breakfast. After a long time, they are prone to chronic gastritis, ulcers and indigestion.
Third, staying up late will affect the excitability of muscles. After a night's rest, my muscles relaxed more in the morning. Getting up immediately after waking up can aggravate muscle blood circulation and increase blood supply, which is conducive to muscle fiber thickening. However, people in bed are in a state of relaxation for a long time, with poor muscle repair and metabolites not eliminated in time. After getting up, they will feel weak legs and waist discomfort.
Fourth, babies who always sleep late will also affect their memory and reduce their learning efficiency after school. Therefore, "getting up at dawn" is a good living habit. Even on holidays, we should keep a normal life rule, go to bed and get up on time.
The sudden change of sleep habits will have a fierce impact on the hypothalamus responsible for hormone balance in the brain, which will lead to hormone imbalance and headache. And staying up late will miss breakfast, causing eating disorders.
Why do many people like to sleep late in the morning?
A study by physiologists found that people breathe slowly during sleep and the carbon dioxide in their blood increases. If they sleep more than ten hours a day, the carbon dioxide accumulated in the blood will become an anesthetic in the human body, which makes people feel groggy, which is why people want to sleep more and more.
Some people like to sleep late, especially on weekends or holidays. In fact, lying in bed is not good for your health. At the same time, long-term sleep will also reduce the excitability of people's cerebral cortex because of depression for too long, leading to slow response and memory decline. In addition, due to the decrease of basal metabolism during sleep, excess calories will be converted into fat and accumulated in the body, making people fat.
So try to control too much sleep.
solution
1, refreshing exercise makes you stay in bed!
Getting up every morning is a painful struggle, and my head is still groggy after getting up. What should I do? Some gymnastics can help you open your eyes and greet the new day with energy! Miss Zhang, who works in a publishing house, often overslept recently because she didn't hear the alarm clock go off. When she opened her eyes, she found that she was almost late for work. She hurried out and put on makeup on the bus. When I arrived at the company, my head seemed to be clear. Not only did I forget the East and the West, but I couldn't come up with any good ideas at the meeting. "I also want to wake up in the warm sunshine every day. Yesterday's fatigue disappeared like the morning mist, and then I went out refreshed ... "She laughed at herself. This is everyone's wish, and now some gymnastics can make this wish come true.
Step 2 focus on the back
Stretch your back and neck and switch your sleeping body to an active state. Because the muscles in sleep are relaxed, the body is particularly soft when getting up, but the back is compressed when sleeping, so the back is stiff instead. However, the central nervous system of the active body is in the neck and back. If you don't relax your back and improve blood circulation, it's hard for your active nerves to wake up. Moreover, the nerve extends from the spine to the whole body, and the outlet is compressed, which will of course make the activity of the body worse. At this time, the back stretching exercise that can be done in bed can come in handy immediately. Stretching back muscles, promoting blood circulation, breathing together and inhaling a lot of oxygen can prepare the body for activities.
Step 3: Breathe faster.
Breathing is divided into unconscious breathing and conscious breathing. Conscious breathing is used to control autonomic nerves. Just like exercise, consciously accelerating the rhythm of breathing will gradually accelerate the heartbeat and make the body enter an active state.
4, the whole body stretching action
In addition, the whole body stretching after getting up can wake up the muscles. Stretching gymnastics can also soften tendons, ligaments, joints and active nervous system. There are nerve cells in the muscle. If you don't stretch your muscles, nerve transmission will be slower. Especially when sleeping, it is very necessary to keep the same posture for a long time and stretch the whole body.
