In a study published in the journal 'Sleep 2010', researchers at West Virginia University School of Medicine reviewed data on 30 397 people who participated in the study of the 2005 National Health Interview. The study found that those who slept less than seven hours a night, a higher risk of heart disease. In addition, women under 60 who slept less than 5 hours, risk 2-fold higher risk for heart disease.
2. Diabetes
Based on the journals diabetes in 2011, research conducted by the University of Chicago and Northwestern University found that people with diabetes who sleep less may develop glucose production by 9%, fasting insulin levels (fasting insulin) by 30%, and insulin resistance increased to 43 %. Blood sugar control is one of the many processes regulated by the body's biological clock, which is one way to sleep. Disruption of the sleep process that will have a direct impact on blood sugar control.
3. Breast Cancer
Research at the Faculty of Medicine, Tohoku University in Sendai, Japan found that approximately 24,000 women with a vulnerable age 40 to 79 years who slept less than 6 hours a day, has a 62% higher risk of developing breast cancer than those who slept more than 9 hours every night.
4. Urine trouble
In findings presented at the American Urological Association in 2011, researchers at the New England Research Institutes in Watertown, MA, reviewed data from 4145 middle-aged men and women who have trouble sleeping. Results are found, lack of sleep in a period of 5 years (less than 5 hours of sleep a night) will increase from 80 to 90% risk in women, and 34% in men to get up at night and urinate (nocturia) or even bed-wetting. The researchers theorize that sleep deprivation can cause inflammation, which in turn can cause problems in the bladder.
5. Colon cancer
In a study of 1240 people last published in 2011, researchers from Case Western University found that those who slept less than 6 hours a night have an increased risk of 47% more likely to develop colorectal polyps, which can lead to cancer, than those who slept 7 minimal hours a night.
6. Death
Study of 16,000 people for 10 years conducted by researchers at the University of Copenhagen connecting point between lacks of sleep with increased risk of death. Apparently the people, who have poor sleep patterns, especially those less than 45 years old, have a mortality risk twice as high.
In addition, those with three or more disorders during sleep at night, have a risk of suicide five times higher than those whose sleep is disturbed. The study also reported that those with sleep disorders tend to have high blood pressure and diabetes.
