What Happens to the Immune System When We Don't Get Enough Sleep?
Sleep deprivation can have several negative effects on the immune system. Chronic lack of sleep can lead to a reduction in the number of _natural killer cells_, which are crucial for defending the body against viruses and tumors. Additionally, sleep deprivation can disrupt the balance of _pro-inflammatory_ and _anti-inflammatory cytokines_, leading to a heightened inflammatory response. This can make individuals more prone to infections and chronic diseases such as cardiovascular disease and diabetes.
