Sleep is of extreme importance for the overall health of the individual, both, mentally and physically. It is a way to recharge after the long and stressful day.
While sleeping, millions of processes continue to happen in the body, helping the brain to store the important data in the memory, and the cells work to repair the damaged tissue and regenerate.
On the other hand, when we lack sleep, all these functions fail to be done on time, and we wake up cranky and have difficulties to concentrate the entire day, but what’s more important, we experience numerous side effects which can significantly endanger our health.
Studies have found that sleep deprivation can cause serious, even life-threatening conditions, from heart diseases, diabetes, to cancer. These are the 6 diseases which are caused by the lack of sleep:
- Cardiovascular Disease
The link between heart problems and the lack of sleep has been suggested numerous times before, but the strongest evidence for the strong correlation has been found by a recent study and presented at EuroHeartCare, the annual meeting of the European Society of Cardiology.
For 14 years, the team of researchers followed 657 Russian men between the ages of 25 and 64 and found that two-thirds of the individuals who experienced a heart attack had a sleep disorder as well.
Moreover, the men who complained to have sleep disorders also had a 1/5 to 4 times greater stroke risk, and 2.6 times higher risk of myocardial infarction.
- Ulcerative colitis
According to a 2014 study, sleep deprivation, and excess sleep may lead to ulcerative colitis, which is an inflammatory bowel disease manifested by ulcers within the lining of the digestive tract, as well as Crohn’s Disease.
The findings of experts from Massachusetts General Hospital show that the adequate amount of sleep is of vital importance in order to curb inflammation responses within the digestive system which often causes these diseases.
Researchers studied women enrolled in the Nurses’ Health Study (NHS) I since 1976 and NHS II since 1989, and discovered that the risks of ulcerative colitis were raised as sleep per night was reduced to 6 hours or less.
Also, they found that 9 hours of sleep also raised the risks, meaning that the proper amount of sleep is a must in the prevention of these diseases.
Even though the results were found in adult women only, the increased risk of developing ulcerative colitis in the case of sleep deprivation existed despite other factors as well, including weight, age, and habits such as drinking or smoking.
