Sleep deprivation on human immune function
Cell activity gradually returned to normal. Observed in 20 cases of cadets after 48h of sleep deprivation cellular and humoral immunity , the results showed : NK cells was significantly reduced. T cell subsets and humoral immune function did not change significantly , indicating that short-term sleep deprivation is affected noon NK cells, and T cell subsets and humoral immune function from the affected, but with prolonged sleep deprivation . T cell subsets and humoral immune function would change needs further study. Studies have shown that [11 ] 】 , sleep deprivation during the circadian rhythm of plasma cortisol levels remain unchanged. In the sleep deprivation during the study period . Subjects without mental stress , indicating that NK cell numbers during sleep deprivation , activity decreased. And the PWM response to changes in endocrine function is not increased , but the changes are the cause of sleep deprivation , indicating that sleep deprivation influence on human immune function ,[link widoczny dla zalogowanych], which also shows that sleep and immune function are closely related experience in electrical burn treatment the number of NK cells Reduction function to reduce the body 48h of sleep deprivation has no significant impact, but a longer period of sleep deprivation . Is easily lead to human disease infection . Currently not been reported ,[link widoczny dla zalogowanych], but the long-term sleep deprivation on rat experimental study : long-term sleep deprivation , the rat skin - Black ,[link widoczny dla zalogowanych], 2 to 4 weeks after the deaths of bacteremia , death and the autopsy found no morphological Pathological changes. We speculate that the death of rats may reduce the number of NK cells . Immune function have been reduced ,[link widoczny dla zalogowanych], and other disorders. Human long-term sleep deprivation certainly the case.
