Applying the actor–partner interdependence model, we examined dyadic associations of broader conscientiousness and its six facets and changes in health, health behavior, and well-being in middle-aged and older couples. However, less is known about how various facets of conscientiousness, of both individuals and their partners, are associated with changes in health in older adults over time. Previous studies show consistent associations between conscientiousness and health outcomes. This information might be considered when providing lifestyle recommendations to adults with and without cognitive complaints.
Our data confirm the absence of association between napping and global cognition and memory regardless of the characteristics of the population. These associations were not modified by individual or sleep characteristics. The pooled ORs from the longitudinal analyses were 1.00 (95% 0.85 to 1.18) for global cognition and 1.08 (95% 0.98 to 1.19) for memory. The pooled ORs from the cross-sectional analyses were 1.03 (95% CI: 1.01 to 1.06) for global cognition and 1.06 (95%: 0.90 to 1.26) for memory.
Twenty-five studies were included in this systematic review and meta-analysis, 18 cross-sectional and seven longitudinal studies, including 95,719 participants older than 60 years. The mean age, the night sleep time (hours), and the percentage of women, no nappers, and people in the less night-time sleep duration category were used for meta-regressions. DerSimonian and Lair and Hartung-Knapp-Sidik-Jonkman random effects methods were used to compute pooled estimates of odds ratios (ORs) and their respective 95% confidence intervals (95% CIs) for the association of global cognition and memory with napping. We systematically searched Medline (via PubMed), Web of Science, and Scopus. This systematic review and meta-analysis aimed to elucidate the cross-sectional and longitudinal relationships between napping and cognitive function (global cognition and memory) and to explore whether some individual characteristics and sleep characteristics can modify this relationship. The Sleep Calculator website reads: "Getting a good night's sleep is about more than simply going to bed early – it's about waking up at the right time too.No clear evidence is available for the influence of napping on cognitive function in older adults. You can even be really preciseįor example, if you know getting out of bed at 6:35 is the optimum time so you can not miss the train and be punctual for work, enter it into the sleep calculator and you'll get a result.įor a 6.35am rise time, go to bed at 9.21pm, 10.51pm, 12.21am or 1.51am. The fifth stage, REM sleep, is when most dreaming occurs. It is difficult to wake someone in Stage 4 of a sleep cycle, which is why you might feel more groggy if you wake up during this stage. We move from light sleep in Stage 1 to a very deep sleep in Stage 4. What are sleep cycles?Ī sleep cycle lasts about 90 minutes, during which time we move through five stages of sleep - four stages of non-rapid eye movement (NREM) sleep and one stage of rapid eye movement (REM) sleep. Here's what time you need to go to bed for an 8am rise: 10.46pm, 12.16am, 1.46am or 3.16am. Can't sleep at night? You may be suffering from these hidden health problemsĭon't need to get up super early to get to work on time?
