People are often difficult to sleep or less sleep, have a high risk of various diseases. Not only fatigue the next day, lack of sleep can lead to diseases that are life-threatening.

Here are some diseases that need to be aware when you are sleep deprived, as reported by the prevention:

1. Heart disease
In a 2010 study published in the journal Sleep, researchers at West Virginia University School of Medicine reviewed data from 30 397 people who participated in the 2005 National Health Interview Study.

Researchers found that people who sleep less than 7 hours a night had an increased risk of heart disease. In particular, women under 60 years who slept 5 hours or less each night, have twice the risk for developing heart disease.

2. Diabetes
Based on a study in the journal diabetes in 2011, researchers from the University of Chicago and Northwestern University found people with type 2 diabetes who sleep less at night have a level of 9 percent higher glucose, insulin levels 30 percent higher and insulin resistance rates 43 percent higher.

Diabetic patients with insomnia even worse condition, glucose levels can be 23 percent higher, rate 48 percent higher insulin and insulin resistance rates 82 percent higher than diabetics who do not have insomnia.

3. Breast cancer
Researchers at Tohoku University Graduate School of Medicine in Sendai, Japan, studied data from nearly 24,000 women age 40 to 79 years and know that women who slept less than 6 hours a night have a 62 percent higher risk for breast cancer.

4. Problems in the urinary tract
In findings presented at the American Urological Association, researchers at the New England Research Institutes in Watertown, MA, reviewed data from 4145 middle-aged men and women.

The result, five years experience restless sleep or too little (less than 5 hours per night) could increase 80 to 90 percent risk of a woman waking up at night to urinate (nocturia) or become wet.

Researchers theorize that sleep deprivation causes inflammation, which in turn can cause problems in the urinary tract.

5. Colon cancer
In a study published in 1240 people in 2011, researchers from Case Western University found that people who sleep less than 6 hours per night, 47 percent higher risk of having colorectal polyps, which can become cancerous, than people who have at least 7 hours of sleep hours.

6. Death
A 10-year study of 16,000 people by researchers at the University of Copenhagen link between sleep deprivation and increased risk of death. The result, it follows that men who reported poor sleep, especially those under 45 years old, had double the risk of death than men who get enough sleep.

And men who have three or more nights of sleep disorders have an increased risk of suicide five times higher than men who sleep undisturbed.
