A study published in the Proceedings of the National Academy of Sciences by the University of Surrey in the United Kingdom found that lack of sleep changes genes. Sleeping less than 6 hours a night for a week can cause changes in more than 700 genes in the body. Even one night of sleep deprivation can wreak havoc on a person.
14 dangers caused by long-term sleep deprivation
1. Decreased immunity
A study from Carnegie Mellon University in the United States found that sleeping less than 7 hours a night can damage the immune system and triple the risk of colds.
2. Easily become ugly
Lack of sleep can easily lead to a dull complexion, loss of charm, and loss of affinity. A study by Sweden’s Karolinska Institute found that sleep deprivation will accelerate skin aging.
3. Easily become stupid
A study published in the American “Sleep” magazine found that one night of sleep deprivation can lead to a decrease in brain tissue, which is the same as the increase in blood test levels of two brain molecules after brain damage.
4. Easy to overeat
Multiple studies have shown that people who are short-term sleep deprived are more likely to overeat, eat more high-calorie, high-carbohydrate foods, and eat greasier foods.
5. Increased risk of car accidents
The American “Prevention” magazine published a study by the American Sleep Foundation that found that sleeping less than 6 hours a night will triple the risk of car accidents. The main reasons include: lack of sleep affects the coordination of the eyes and the dexterity of the hands and feet.
6. Losing control of emotions
A study conducted by scientists at the University of California, Berkeley, and Harvard Medical School found that a night’s sleep deprivation can lead to increased activity in the brain areas responsible for emotional management, indicating that sleep deprivation can easily lead to emotional loss.
7. Diminished concentration
A Harvard study found that sleep deprivation affects the brain’s memory enhancement process, which in turn affects information retrieval and the input of new information.
8. The risk of stroke increases by 4 times
A study by the University of Alabama in the United States found that middle-aged and elderly people who sleep less than 6 hours a night are four times more likely to have a stroke than those who sleep 7 to 8 hours a night.
9. The risk of obesity increases sharply
An article in the American Journal of Human Biology points out that multiple studies have found that long-term sleep deprivation can change regular appetite and lead to overeating, thereby increasing the risk of obesity.
10. Increased risk of certain cancers
A study of 1,240 participants who underwent colonoscopies found that those who slept less than 6 hours a night had a 50% increased risk of developing intestinal polyps (pre-colon cancer).
A 2012 study found that sleep deprivation can increase the risk of breast cancer.
11. The risk of diabetes increases
A 2013 study by the U.S. Centers for Disease Control and Prevention found that getting too much or too little sleep increases the risk of chronic diseases such as type 2 diabetes.
A 2012 study found that too little sleep can reduce insulin sensitivity and increase the risk of diabetes.
12. Increased risk of heart disease
A study published in Harvard Health Letter found that chronic sleep deprivation is closely related to high blood pressure, arteriosclerosis, heart failure and heart attack.
Sleeping less than 6 hours a night increases the risk of heart disease and stroke by 48% and 15% respectively.
13. Reduced sperm count
A 2013 study published in the American Journal of Epidemiology found that sleep deprivation can lead to a 29% decrease in sperm concentration.
14. Increased risk of premature death
A 10 to 14-year study published in the journal “Sleep” involving 1,741 male and female participants found that men who slept less than 6 hours a night were significantly associated with increased mortality.
