Staying up late can reduce cognitive function in the brain, experts say, whether it’s reducing sleep by 2 hours a day for two weeks straight or not sleeping for 48 hours straight.
Can I make up for staying up all night? Some studies have shown that it takes about a week on average for learning and memory levels to recover from a night without sleep. It’s really hard to make up for staying up too late.
What exactly are the dangers of staying up late? What are the main hazards of staying up late?
Harm to the cardiovascular system
Nighttime is supposed to be the time when the human body should rest, if the body can’t rest, it should be given a certain intensity of stimulation.
Some information shows that staying up late can make the average secretion of various hormones in the human body 5% higher than the average person, these hormones are like stimulants to stimulate the body to maintain a state of excitement to maintain normal activities.
But the increased level of hormones will also bring a series of problems, especially the increase in epinephrine and norepinephrine, which will cause vasoconstriction, blood pressure rise, and the increase in blood viscosity, which may lead to cardiovascular For patients with cardiovascular stenosis, heart attack may occur, leading to sudden death.
Harm to the digestive system
People who stay up late have the habit of eating late night snacks, we know that the epithelium of the human gastric mucosa is generally regenerated once in 2 to 3 days, the time of this repair is generally carried out at night when there is no food in the stomach, that is, at night people sleep to repair.
If we often snack, or irregular meals, so that the gastrointestinal tract can not get rest, the gastric mucosa can not be repaired and regenerated, over time, it will lead to gastric mucosa erosion, ulcers, can also lead to loss of appetite, indigestion. If it is not treated in time, it may lead to the occurrence of stomach cancer.
Staying up late can make people fatigued and mentally weak, and the body’s resistance can be reduced. At the same time, the ability to resist various diseases also decreases, such as: people who stay up late are often prone to colds, gastroenteritis and other diseases.
Japanese research concluded that people who stay up late for a long time are more likely to develop cancer than normal people, such as the incidence of pancreatic cancer in people who stay up late is more than 3 times higher than those who do not stay up late.
Australian scientists believe that nighttime is the peak period of cell fission in the body, if you do not sleep well or do not sleep, it is difficult for the body to control the cell fission, which leads to cell cancer.
We all have the experience that if we don’t have a good rest on the first night, we will have no energy, dizziness, headache, memory loss, lack of concentration, work efficiency and reaction ability will be significantly reduced during the daytime the next day.
This is because the body does not get a good rest, stay up late so that the sympathetic nerves should be excited during the day, “overtime” at night to occur abnormal excitement, and in the next day, the sympathetic nerves fatigue, and can not continue to be excited, there will be the above performance.
Over time, there will be neurasthenia, insomnia and other serious health problems.
