During the sleeping, the human’s body continues to work, conducting numerous activities, such as growth and cell repair, as well as on restoring energy and nutrients to worn out muscles and tissues.
If you sleep well, you’ll be able to balance out hormones and support your immune system in order to support memory function. In contrary, the poor sleep can leave you feeling not only cranky and groggy but also less focused and more forgetful.
Sleep Deprivation and Diseases
Here are 6 conditions that are directly caused by lack of sleep:
During the sleeping, the body removes the waste from tired brain cells as well as repairs worn or damaged structures. If that isn’t done properly because of a shortage of time, then cognitive decline, dementia, and other brain conditions may occur.
The research conducted in 2013 at Johns Hopkins University showed that bad (or not) sleeping is one of the main reasons of Alzheimer’s disease. The study was conducted on 70 adults between the ages of 53 and 91. Participants with poor sleep were found to have higher quantities of beta-amyloid deposition in their brains on PET scans, which is a marker for Alzheimer’s disease. According to the researchers, the poor sleep prevented the brain from clearing up beta-amyloid “waste”, which can lead to a risk of the cerebral disease.
- Obesity and Diabetes
At the University of Chicago was conducted a study that showed linkage of the poor sleep with the obesity, and ultimately, diabetes.
The results lead to the conclusion that lack of sleep causes a fatty acid buildup, which impacted both insulin sensitivity and metabolism. There were analyzed sleeping patterns of 19 men over 3 nights. The results that researchers found were that men with only 4 hours of sleep had fatty acid blood levels 15 to 30 percent higher than participants who slept 8.5 hours a night.
The people who sleep shorter also showed signs of obesity and pre diabetes while those people who had enough sleep did not.
- Cardiovascular Disease
In fact, the diet and lifestyle are two main factors that affect the health of your heart. As your sleeping is part of your lifestyle, then if you sleep less than it is recommended, you can be at risk of cardiovascular diseases, too.
In the study ordered by the European Society of Cardiology, which followed 657 Russian men aged 24-64 for a total of 14 years, were showed significant results that show the linkage between the sleeping and heart problems. There was found that two-thirds of the participants who experienced a heart attack also suffered from a sleeping disorder.
Poor sleepers in this study were also found to have 2.6 times greater risk of myocardial infarction (caused by the heart muscle dying), and even had a greater risk of stroke.
The serious mental health problems are also caused by the lack of sleep.
In a 2014 study were confirmed links between incidences of suicide in adults and poor sleep, regardless of past attacks of depression.
The Stanford University of Medicine also conducted a 10 years study, examining 420 young and middle-aged adults. The fact was really shocking because 20 of the participants who suffered from poor sleep committed suicide.
- Ulcerative Colitis
The numerous studies have found that ulcerative colitis as an inflammatory bowel disease is heavy correlated to sleep deprivation.
According to the researchers from Massachusetts General, and their study published in 2014, the women who slept 6 hours of sleep or less (despite age, smoking, weight, and drinking) were more likely to suffer from ulcerative colitis.
However, getting more than 9 hours of sleep is not also recommended, as it puts the women at risk, too. The only getting the right amount of sleep every night is key to controlling inflammation in the digestive tract.
- Prostate Cancer
The researchers, also found that sleep can actually protect your prostate as it is linked to the melatonin, a sleep hormone.
The Icelandic researchers conducted for 3-7 years study, followed by 2,425 Icelandic 67 to 96 years old, who examined their sleeping patterns.
The results showed that the men who had trouble sleeping were 60% more likely to develop prostate cancer. But, even worse happened with the men who had trouble staying asleep, as they were nearly 120% more likely to be affected by this disease.
