Anxiety and insomnia linked to sharp drops in key immune cells

Thanh Nham Dec 20, 2025, 3:20 PM

Natural killer (NK) cells act as key defenders within the immune system. They help control infections by targeting invading microbes, foreign materials, and damaged or infected cells early on, which limits their ability to spread. NK cells travel through the bloodstream (circulatory) or remain in specific tissues and organs. When NK cell numbers drop too low, the immune system may no longer function properly, increasing the risk of illness.
