                    Snippet: Sleep and the circadian system exert a regulatory influence on immune functions. Sleep deprivation can affect immune function in several ways including reduced natural killer cell activity, suppressed interleukin-2 production and increased levels of circulating proinflammatory cytokines [83, 84] . There is also evidence for an enhanced susceptibility to the common cold and pneumonia with poor sleep efficiency [85, 86] ......
