title: Effects of mental resilience on neuroendocrine hormones level changes induced by sleep deprivation in servicemen.
abstract: The aim of this study was to investigate the effects of mental resilience on the changes of serum rennin, angiotensin, and cortisol level induced by sleep deprivation in servicemen. By random cluster sampling, a total of 160 servicemen, aged from 18 to 30, were selected to undergo 24-hour total sleep deprivation and administered the military personnel mental resilience scale after the deprivation procedure. The sleep deprivation procedure started at 8 a.m. on Day 8 and ended at 8 a.m. on Day 9 after 7 days of normal sleep for baseline preparation. Blood samples were drawn from the 160 participants at 8 a.m. respectively on Day 8 and Day 9 for hormonal measurements. All blood samples were analyzed using radioimmunoassay. As hypothesized, serum rennin, angiotensin II, and cortisol level of the participants after sleep deprivation were significantly higher than those before (P < 0.05). The changes of serum rennin and cortisol in the lower mental resilience subgroup were significantly greater (P < 0.05); problem-solving skill and willpower were the leading influence factors for the increases of serum rennin and cortisol respectively induced by sleep deprivation. We conclude that mental resilience plays a significant role in alleviating the changes of neurohormones level induced by sleep deprivation in servicemen.
