If you've ever spent a night spinning around and around, you know how you'll feel the next day: tired, cranky and out of place. While you sleep, your body performs countless activities, including cell growth and repair. It also works to restore energy and nutrients from worn muscles and tissues.
Sleep also balances hormones and supports your immune system while working to support memory function.
Here are 5 conditions directly caused by very little sleep.
Since sleep is necessary to eliminate waste from tired brain cells, as well as to repair worn or damaged structures. If this is not done correctly, cognitive impairment, dementia, and other brain conditions may occur. In fact, in 2013, researchers at Johns Hopkins University discovered that skipping sleep is one of the possible causes of Alzheimer's disease.
In one study, participants who experienced lack of sleep were often found to have higher amounts of beta-amyloid deposition in their brains on PET scans.
The lack of sleep prevented the brain from eliminating the "waste" of beta-amyloid, which led to a higher incidence of brain disease.
2. Obesity and diabetes
Researchers at the University of Chicago have shown that lack of sleep is related to obesity and, ultimately, to diabetes.
They discovered that very little sleep led to the accumulation of fatty acids, which affected both metabolism and insulin sensitivity. When analyzing the sleep pattern of 19 men for 3 nights, the researchers found that men who slept only 4 hours had blood fatty acid levels 15 to 30 percent higher than participants who slept 8.5 hours per night.
People who slept little also showed signs of pre-diabetes and obesity, while people who slept more did not.
3. Cardiovascular diseases.
Cardiovascular diseases are heavily influenced by diet and lifestyle, so it is not surprising that sleep comes into play.
One study found that two-thirds of those who suffered a heart attack also suffered from a sleep disorder.
It was also found that those who sleep poorly have a 2.6 times higher risk of myocardial infarction, a heart attack caused by the death of the heart muscle. They even had a stroke risk of one and a half to four times greater.
4. Lack of sleep ages your skin
Most people have experienced pale skin and swollen eyes after a few nights of lost sleep. But it turns out that chronic loss of sleep can lead to dull skin, fine lines and dark circles under the eyes.
When you do not sleep enough, your body releases more stress hormone, cortisol. In excessive amounts, cortisol can break down the collagen in the skin, the protein that keeps it soft and elastic.
5. Losing your sleep can make you gain weight
When it comes to body weight, it may be that if you sleep, you lose. Lack of sleep seems to be related to an increase in hunger and appetite, and possibly obesity. According to a 2004 study, people who sleep less than six hours a day were nearly 30% more likely to become obese than those who slept 7 to 9 hours.
