1. Cardiovascular diseases
In an article published in the journal Sleep on 20/0/0, researchers from the Medical College of West Virginia University reviewed the data of 30,397 subjects who participated in the national health interview study in 2005. They found that people who sleep less than seven hours a night have an increased risk of heart disease. Especially those women under 60 who sleep less than 5 hours a night, their risk of heart disease has tripled.
2. Diabetes
According to a study published in the journal Diabetes on 20 1 1, researchers from the University of Chicago and Northwestern University found that if patients with type 2 diabetes don't sleep well at night, their fasting blood glucose level will be 9% higher, their fasting insulin level will be 30% higher and their insulin resistance level will be 43% higher. Insomnia in diabetics is even worse. Compared with diabetic patients without insomnia, their fasting blood glucose level is 23% higher, their fasting insulin level is 48% higher and their insulin resistance level is 82% higher.
3. Breast cancer
Scholars from the Medical Research Institute of Tohoku University in Japan have studied the data of nearly 24,000 women aged between 40 and 79, and found that those who sleep less than 6 hours a night have a higher risk of breast cancer, while those who sleep more than 9 hours a night have a lower risk of breast cancer.
4. Urinary system problems
At the meeting of American Urology Association in May, 20 1 1, scholars from New England Institute reviewed the data from 4 145 middle-aged men and women, and found the following information: within five years, if women have poor sleep or lack of sleep (less than five hours every night), the risk of getting up at night (enuresis) or urinary incontinence will increase by 80%. 42% of women classify themselves as restless sleepers, and 34% of men belong to this category. The researchers concluded that lack of sleep can lead to inflammation, which can lead to some urinary system problems.
5. Colon cancer
In a study published on 20 1 1, there were 1240 subjects. Researchers at Case Western University found that people who sleep less than 6 hours a night have a 47% higher risk of colorectal polyps than those who sleep at least 7 hours.
6. Mortality
In a study with a history of 10 years, 16000 people participated in the survey. Researchers at the University of Copenhagen in Denmark linked lack of sleep to mortality and found that men who reported poor sleep, especially men under 45, had twice the risk of death as men who slept well. Men whose sleep is disturbed three or four times a night have five times the risk of suicide as those who are not disturbed. Although sleep disorder does not affect the mortality rate of women, both men and women with sleep disorder are at higher risk of hypertension and diabetes.
