Suppressed Immune System
Your body produces cytokines and other infection-fighting substances while you are sleeping. These tools are essential for fighting off viruses and bacteria. However, if you are not getting enough sleep, then your body will not have enough time to produce these substances. This can put you at risk for a number of illnesses. It can also make it harder for you to recover from illnesses.
There are several reasons sleep deprivation can lead to weight gain. If you are sleep-deprived, then your body will produce more ghrelin and less leptin. Ghrelin stimulates your appetite while leptin suppresses it. Sleep deprivation also slows down your metabolism. Additionally, people have a tendency to crave unhealthy foods when they are sleep-deprived.
Because you are more likely to gain weight if you are sleep-deprived, sleep deprivation can put you at risk for developing heart problems. Heart disease has been linked to obesity. Sleep deprivation can also increase the risk of high blood pressure and heart disease.
When people say that they need to get their beauty sleep, they are telling the truth. A lack of sleep can lead to hormonal balances that cause breakouts. Sleep deprivation can also lead to wrinkles. Your body produces collagen while you are sleeping, which protects against wrinkles.
