So, why do you feel sleepy after sleeping for 8 hours?
In fact, it does not mean that people who sleep for 8 hours a day will not feel sleepy. It also involves many factors such as sleep quality, seasonal changes, physical state and physique, environment and so on.
Sleep quality is not high. Generally speaking, the proportion of deep sleep accounts for more than a quarter of high-quality sleep. People who lack deep sleep seem to sleep for 8 hours, but during the sleep process, because the proportion of deep sleep is far less than a quarter, the body can not get full relaxation and rest. After waking up, the body is still more likely to feel tired and sleepy during the day.
Seasonal factors Sometimes the changes of weather, temperature and humidity in different seasons may make people sleepy. The so-called "spring sleepy, autumn sleepy, summer sleepy, winter sleepy and March sleepy" refers to the influence of seasons on people. I believe many people have experienced this inexplicable sleepiness all year round, especially in spring, because the weather gets warmer in spring, the skin pores and blood vessels in the body begin to stretch and expand. The blood supply also began to increase, but the oxygen supply to the brain decreased accordingly. At this time, the brain will reduce its excitement to adapt and protect itself, so it will be sleepy.
Physical state and personal physique When a person's body is in a relatively tired or weak state, it is easier to feel sleepy. At present, the pace of life is too fast and many people are under too much pressure. It's easy to neglect one's health and basic nutrition supplements, such as rich fruits and vegetables and protein intake, because of high-intensity work. In this way, their resistance will drop and their bodies will become weak and tired.
Especially in protein, about 3% of adults' protein needs to be updated every day to maintain their daily basal metabolism. Therefore, if protein's intake is insufficient, the body's resistance will decline, and it is inevitable that you will be in a state of fatigue for a long time.
? Environmental impact? People are more likely to feel sleepy under certain circumstances. For example, sitting in a warm and comfortable room after eating and drinking, it is particularly quiet around, and people are particularly prone to drowsiness, and even fall asleep unconsciously; For example, on a long-distance bus, most passengers will feel sleepy because of the jolting and shaking of the car, because this rhythmic shaking will make people's brains generate sleepy radio waves and enter hypnosis mode; When you are in a boring environment, sometimes you may feel sleepy.
According to the advice given by relevant experts, not all factors need intervention: you don't have to worry too much about the drowsiness caused by seasonal factors and environmental influences, because most people will have such a situation. If it does affect work efficiency, you can also actively intervene; But we must pay attention to the sleepy plot caused by poor sleep quality and poor physical condition.
With regard to improving sleep quality, it is suggested to increase the proportion of deep sleep.
Mainly to arrange sleep time reasonably. Hormones that regulate sleep will peak in the early hours of the morning. Therefore, try to go to bed before 1 1 at night, and try to stay away from mobile phones and computers before going to bed, so that your mood will tend to be peaceful and it will be easier to get a deep sleep.
In addition, it will be a good supplement to arrange a lunch break within 30 minutes at noon. By the end of lunch, the brain had been hollowed out and the stomach had just been filled. Nothing is more refreshing than taking a nap. Facts have proved that this method is indeed more effective than drinking coffee and is more conducive to health.
With regard to improving physical condition and physique, it is suggested to start with daily living habits.
Do more stretching exercises when you get up in the morning. When we stretch, most of our muscles contract, so that blood will flow back to the heart, which can speed up metabolism and relieve physical fatigue.
When the body feels tired but can't rest immediately, you can try to do several groups of chest expansion exercises to make the blood in the body circulate quickly between the heart and the brain, which is helpful to eliminate fatigue; If you feel sleepy at this time, you can also try to knead it with the tip of your middle finger to achieve a quick refreshing effect.
Pay more attention to enhancing nutrition at ordinary times. We can get protein from fruits and vegetables, milk, meat, eggs and other foods rich in protein. Besides these, we can also supplement protein with protein powder. We should also pay attention to strengthening physical exercise. People with weak constitution are often more prone to fatigue than others, so a healthy and reasonable diet and at least half an hour of exercise every day are also helpful to improve their physical condition.
In addition, the reason why some people are often sleepy may also be pathological. In this case, it is necessary to actively seek medical treatment and seek more professional help.
