First, it causes serious health problems.
Long-term lack of sleep will increase your risk of these diseases: heart disease, heart attack, heart failure, arrhythmia, high blood pressure, stroke and diabetes. It is estimated that 90% of insomnia patients (people who are characterized by difficulty in falling asleep and easy to wake up) are accompanied by other health problems.
Second, the resistance is weak.
Long-term lack of sleep will weaken the resistance, because if the body wants to stay healthy, it needs enough rest time to make the organs work normally, and the immune function can also play a normal role when the body organs remain healthy.
However, many people have bad habits of staying up late and not getting enough sleep. As a result, the immune function cannot function normally. The main manifestation is weak resistance, which may increase the prevalence of diseases. Therefore, we should pay attention to the law of work and rest and enhance immune function by ensuring adequate sleep time.
Third, it affects liver function.
Always lack of sleep, the main effect is that the liver is easily damaged. As a very important organ of human body, liver has the ability to excrete toxins. In the process of sleeping at night, the liver can also play an important role in expelling toxins from the body and maintaining good health.
Frequent lack of sleep misses the best opportunity for the liver to excrete toxins, which may affect its function, hinder the excretion of toxins and increase the possibility of liver lesions. Therefore, the key to maintaining the liver and preventing liver fire is to have enough sleep time and pay attention to the rules of work and rest.
Fourth, a lot of hair loss.
Sleeping time is also the key time for hair to get nutrition. Because only cerebral cortex activities consume14 of the nutrients needed by human metabolism and daily activities in a day, most of the blood transported by the neck and brain is concentrated in the brain, and the amount of blood transported to the side branches is small, while scalp tissue only relies on the blood supply from the side branches of carotid artery to provide nutrition. If you don't get enough sleep for a long time and don't supply enough blood to your hair at night, your hair will become scarce and inelastic.
Five, emotional impulse
Lack of sleep can also lead to mood swings. A study found that when we don't get enough sleep, we are more likely to be unhappy, because a tired brain stores more negative memories. The behavior of people with insufficient sleep is very similar to that of people with depression. Lack of sleep will make your judgment worse and make you impulsive, such as poor diet, shopping without considering the consequences, irritability and other emotional problems.
Sixth, it will cause obesity.
Many studies have shown that long-term lack of sleep will disturb blood sugar levels, resulting in the body producing less leptin (the hormone that inhibits appetite) and more auxin (the hormone that stimulates appetite). These physiological changes will inevitably lead to overeating. Tired people especially like sweets and other simple carbohydrates, probably because they can fill their stomachs quickly.
Lack of sleep is a very common situation in life. In modern life, many people don't get enough sleep. Therefore, we should fully understand the symptoms and harm of insufficient sleep. Only in this way can we better protect our health and avoid diseases.
