A new study links habitual sleep deprivation to dampened immune responses, reports The (University of Washington) Daily.

“We know this has an impact on performance, cardiovascular disease, metabolic disease, immunity, pain, mortality, and mental health,” said Nathaniel Watson, UW professor of neurology and lead author of the study. Watson also occupies director positions at the Harborview Medical Center Sleep Clinic, and the UW Medicine Sleep Center, and is president of the American Academy of Sleep Medicine.
