IntroductionSelf-reported daytime napping is associated with various adverse health outcomes. We examined whether actigraphy-measured objective daytime napping behaviors predict all-cause mortality in middle-to-older aged adults in the UK Biobank.MethodsWe studied 86,565 participants (baseline age=63 years, SD=8, range: 43-79; 57% female) in the UK Biobank who did not have shiftwork history, completed a 7-day actigraphy monitoring,… Continue reading 0350 Objectively-Assessed #Napping Behaviors Predict #Mortality in Middle-to-Older Aged #Adults

Is there an association between daytime napping, cognitive function, and brain volume? A Mendelian randomization study in the UK Biobank
Highlights•Whether daytime napping is causally associated with brain health remains elusive.•We studied the causal role of daytime napping on cognitive and neuroimaging outcomes.•We found a modest causal link between habitual napping and larger total brain volume. Daytime napping has been associated with cognitive function and brain health in observational studies. However, it remains elusive whether these associations… Continue reading Is there an association between daytime napping, cognitive function, and brain volume?

Association of Nap Frequency With Hypertension or Ischemic Stroke Supported by Prospective Cohort Data and Mendelian Randomization in Predominantly Middle-Aged European Subjects
Background and Purpose:The aim of this study was to investigate the association between daytime napping frequency and the incidence of essential hypertension or stroke as well as to validate causality in this relationship via Mendelian randomization (MR).Methods:We conducted Cox regression analysis on 358 451 participants free of hypertension or stroke from UK Biobank. To validate the… Continue reading Association of Nap Frequency With Hypertension or Ischemic Stroke Supported by Prospective Cohort Data and Mendelian Randomization in Predominantly Middle-Aged European Subjects
Relationship between afternoon #napping and #cognitive function in the ageing Chinese population
Background Several studies have shown that afternoon napping promotes cognitive function in the elderly; on the other hand, some studies have shown opposite results. This current study further examined the relationship between afternoon napping and cognitive function in the ageing Chinese population. Methods A total of 2214 elderly were included (napping group: n=1534; non-napping group:… Continue reading Relationship between afternoon #napping and #cognitive function in the ageing Chinese population

#Sleep duration, midday napping, and sleep quality and incident #stroke The Dongfeng-Tongji cohort
..Compared with sleeping 7 to <8 hours/night, those reporting longer sleep duration (≥9 hours/night) had a greater risk of total stroke (hazard ratio [HR] 1.23; 95% confidence interval [CI] 1.07–1.41), while shorter sleep (<6 hours/night) had no significant effect on stroke risk. The HR (95% CI) of total stroke was 1.25 (1.03–1.53) for midday napping… Continue reading #Sleep duration, midday napping, and sleep quality and incident #stroke The Dongfeng-Tongji cohort
Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.
The aim of the present study was to determine the effect of different nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, stress and sleep. Twenty physically active men (age: 21.1 ± 3.6 years, height: 176.4 ± 5.7 cm, body-mass: 72 ± 10.8 kg) performed the 5-jump and the digit-cancellation (i.e., attention) tests after four randomized nap opportunity conditions: no-nap opportunity… Continue reading Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.
