Lack of sleep weakens our immune system

There are millions of viruses, infections, and bacteria around us, and our immune system helps us fight them off.

If we don’t get enough sleep, there could be problems with the production of cytokines in our body. Therefore, people with sleep deprivation have weakened immune systems and are more vulnerable to various infections. Research has shown that people who sleep less than 7 hours at least two days in a row, are at a 3 times higher risk of getting infections.

Insufficient sleep leads to problems with blood pressure

Lack of sleep puts a higher risk of problems with blood pressure and leads to higher levels of the stress hormone cortisol. Cortisol can be the cause of damage to the walls of blood vessels, and it may lead to atherosclerosis and hypertension.

Sleep deficiency increases the risk of diabetes

If our body doesn’t get enough sleep for some time, it can hurt our metabolism and ability to regulate blood sugar. Poor sleep affects our blood cells and they stop processing glucose properly. Problems with processing glucose put people at a higher risk of type 2 diabetes.

Lack of sleep provokes overeating and obesity

Lack of sleep is tied to overeating and obesity. If our body doesn’t get enough sleep, it needs to take energy from other resources.

Lack of sleep disrupts the production of the hormone melatonin in our body, and this hormone controls our mood. A low level of melatonin is one of the main risk factors for clinical depression.
