Recently, the International Journal of Chronobiology published an important article, “The relationship between work and rest and morbidity and mortality in the UK Biosample”. Night owls who stay up at night and don’t get up in the morning, or have trouble getting up, are at higher risk of “early death” than those who go to bed early and get up early.
The study, based on a sample of nearly 500,000 people in the British biobank, found that people who do not sleep at night and do not get up in the morning have a 10% higher risk of death than those who sleep early and get up early. In the study sample, 50,000 people faced a higher risk of death during the 6.5-year sampling period.
Effects of staying up late on the body
Staying up late for long periods of time can damage general health because, in the human body, both adrenocorticotropic hormone and growth hormone are secreted during nighttime sleep. The former is secreted before dawn and has the function of promoting the body’s sugar metabolism and safeguarding muscle development.
1, wrinkles increase
According to a report by the London School of Sleep, a reduction in sleep by two hours a day for a week can have a serious impact on appearance. The number of fine lines and wrinkles among the women who participated in the survey rose by 45%, and the number of spots rose by 13%. People’s eyes become red and puffy, the skin becomes loose and saggy, and more wrinkles appear.
2. Hair loss
Alopecia areata is a kind of autoimmune non-scarring hair loss, commonly known as “ghost shaving”, in which hair falls out unknowingly. It is mainly caused by emotional factors. Anxiety and shock may also cause baldness. Staying up late at night may cause endocrine disruption, which can also cause baldness.
3.Sudden deafness
Sudden deafness is when you can’t hear all of a sudden when you were fine. Frequent late nights, long-term fatigue, and lack of sleep can hinder the blood supply to the inner ear, which can easily lead to sudden deafness once external stimuli (such as sudden temperature changes and viral infections) are applied.
4. Vision loss
Staying up late can do more harm to your eyes than simply having “panda eyes”. Long-term eye overload will cause pain, dryness and other problems in the eyes, and even make people suffer from dry eye disease; long-term overwork caused by staying up late may also induce central retinitis, resulting in a sudden drop in vision.
5.Neurasthenia
The next day after staying up late, sympathetic nerves are difficult to fully excite, which will make people have no spirit, dizziness, memory loss, inattention, slow reaction, forgetfulness and dizziness, headache, etc.. Over time, more serious problems such as neurasthenia and insomnia can occur.
6, Alzheimer’s disease
Scientists have shown in a recent study that when rats do not get enough sleep, it makes the brain show bad omens and may trigger Alzheimer’s disease (dementia).
7, high blood pressure, sudden death
Studies have shown that long-term sleep deprivation is an important causative factor for hypertension, which also makes late night people suffer from all kinds of sudden cardiovascular disease, the chances of a great increase in serious cases will lead to sudden death.
8, diabetes
For people with a family history of diabetes, staying up late often increases the chances of developing diabetes. Compared to others, people with a family history of diabetes have certain triggers for the disease, and if the conditions are right, like a seed meeting the right environment, it will soon take root and sprout.
9.Cancer
Medical research shows that people who stay up late are more likely to suffer from cancer than those who sleep normally. Take pancreatic cancer as an example, the incidence rate of people who stay up late often is more than three times higher than the average person. Staying up late can affect the normal division of cells, which can lead to cell mutation and produce cancer cells.
10.Immune dysregulation
Staying up late for a long time will lead to immune dysfunction in the body, which is manifested in the kidneys to produce nephritis; in the skin may be lupus erythematosus; in the joints is rheumatoid arthritis …… the body is in a subhealthy state, cold and other whistling diseases, gastroenteritis and other digestive tract diseases will
