How does poor sleep affect your immune system?

ANSWER

Without good sleep, your body produces fewer antibodies to help you fight infection. It also releases fewer proteins called cytokines. Among other things, cytokines fight off inflammation and infection -- and help regulate your sleep. Fewer antibodies and cytokines give you less ammunition to battle a cold or the flu.
