Nowadays, many young people's work and rest are becoming more and more irregular. Staying up late has almost become a routine, and it is also very common not to sleep at one or two. However, I believe everyone has heard the saying that staying up late is equivalent to chronic suicide. Staying up late, poor sleep quality or insufficient sleep time are very easy to bring you many diseases. The small editor of this article will tell you about the harm of insufficient sleep.
The American Heart Association website (AHA) has published articles:
Those who slept 7 to 8 hours a night had a 25% lower risk of stroke, but those who slept more than 8 hours had a 146% higher risk of stroke, while 22% of those who slept less than 7 hours had also reported stroke. How long you sleep at night is closely related to how long you can live!
10 diseases are easy to get if you don't sleep well
01 prone to neurasthenia
People's sympathetic nerves should rest at night and be excited during the day, so as to support people's work all day, while those who lack sleep are excited at night. In the next day, it is difficult to fully excite the sympathetic nerve, which will make people lose spirit, dizziness, brain swelling, memory loss, inattention, slow response, forgetfulness, dizziness and headache. Over time, there will be neurasthenia.
02 prone to Alzheimer's disease
A study published in the journal Nature neurology shows that lack of sleep can lead to the formation of cerebral plaques, which can lead to Alzheimer's disease. The researchers found that the increase of marker proteins in Alzheimer's disease is related to the more disturbed deep sleep mode.
03 prone to sudden deafness
Often staying up late, long-term fatigue and lack of sleep will hinder the blood supply of the inner ear. Once stimulated by external stimuli (such as sudden temperature change, virus infection, etc.), it is easy to lead to sudden deafness.
04 immune dysfunction
The more terrible harm of long-term lack of sleep is the body's immune dysfunction, which is manifested in lupus erythematosus on the skin, rheumatoid arthritis on the joints, and nephritis on the kidneys.
05 getting old and ugly
According to a report from the London sleep school, reducing two hours of sleep a day within a week can have a serious impact on appearance. Among the women surveyed, the number of fine lines and wrinkles increased by 45%, and the number of spots increased by 13%. People's eyes become red and swollen, their skin becomes loose and sagging, and more wrinkles grow.
06 diabetes is easy to get.
For people with family history of diabetes, lack of sleep often increases the risk of diabetes.
07 prone to hypertension
A study published in the medical journal hypertension confirmed that long-term lack of sleep is an important pathogenic factor of hypertension. British scientists have conducted a five-year follow-up survey of more than 10000 adults and found that people who often sleep for only 6 hours or less are 42% more likely to suffer from hypertension than those who sleep for 8 hours, while those who often sleep for no more than 5 hours are 31% more likely to suffer from hypertension.
08 prone to obesity
In addition, there is a more important data show that people who sleep more will be thinner. Because if sleep time is insufficient, it will reduce the amount of hormones with the function of breaking down fat, and increase blood glucose due to difficulty in inhibiting sympathetic nerve activity, which will become the inducement of obesity.
09 increased cancer risk
Lack of sleep will lead to the disorder of human endocrine hormone level, lead to abnormal cell metabolism, affect the normal division of human cells and cause cell mutation. The international agency for research on cancer has long recognized that people who stay up late without enough sleep have a 24% increased risk of advanced cancer and a 49% increased risk of early cancer compared with people who work nine to five.
10 prone to sudden death
"Many of my patients used to work more than ten hours a day. They often stay up late at night and work overtime, resulting in a serious lack of sleep." According to experts in the Department of Cardiology of Beijing Anzhen Hospital, when the human body is in a state of stress for a long time and continuously secretes adrenaline and other hormones, it will cause abnormal vasoconstriction and even induce sudden cardiac death.
