The immune system has different types of white blood cells (leukocytes), such as T cells, B cells, and natural killer cells.

T cells destroy invaders and T helper cells boost immune activity. It is these T helper cells that are targeted by the human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS). B cells produce antibodies. Natural killer cells are involved in fighting both viruses and tumors. Stress can affect the cytotoxicity of natural killer cells, which are of critical importance in defense against various infectious diseases and cancers.

Decreased natural killer cell cytotoxicity has been found in highly stressed people, such as students facing important exams, bereaved family members, and people with severe depression. Studies have shown that immune function is better in individuals who receive social support.
