Seventeen studies, including a total of 36,938,981 individuals followed up for a mean of 11.6 y, reporting the investigation of the association between mortality and frequent (≥3 nights/wk), ongoing (≥1 mo) insomnia were identified.
There was no difference in the odds of mortality for those individuals with symptoms of insomnia when compared to those without symptoms (OR = 1.06, 95%CI = 0.61–1.84, p = .84). This finding was echoed in the assessment of the rate of mortality in those with and without symptoms of insomnia using the outcomes of multivariate models, with the most complete adjustment for potential confounders, as reported by the individual studies included in this meta-analysis (HR = 1.07, 95%CI = .96–.1.19, p = .22). Additional analyses revealed a tendency for an increased risk of mortality associated with hypnotic use.
The current evidence reinforces the use of cognitive therapy, within a CBTi framework, as a frontline non-pharmacological treatment for insomnia to reassure patients their longevity will not be impacted as a consequence of suffering from insomnia
Daily exercise can shift the endogenous circadian phase.
Get PDFBody temperature is elevated during and for a short time following strenuous exercise. The
general question of interest is whether habitual exercise can have an entraining effect on the circadian rhythm of body temperature and other rhythms of the circadian system. It is important to evaluate the relative strengths of potential circadian zeitgebers for their possible use in treating the effects of shift work, jet lag and delayed sleep phase syndrome. Bright light appears to be an effective zeitgeber. (1,2) Can physical exercise be one as well
