Our immune system is designed to protect us from colds, flu, and other ailments, but when it is not functioning properly, it fails to do its job. The consequences can include more sick days.
The relationship between lack of sleep and our immune systems is not quite as straightforward as mom made it out to be, however. The immune system is pretty complex. It is made up of several types of cells and proteins that are charged with keeping foreign invaders such as colds or flu at bay.
A lot of studies show our T-cells go down if we are sleep deprived .And inflammatory cytokines go up. … This could potentially lead to the greater risk of developing a cold or flu.
In simple terms, sleep deprivation suppresses immune system function. The more all-nighters you pull, the more likely you are to decrease your body’s ability to respond to colds or bacterial infections.
