“…It should be noted that a nap can provide benefits but also predispose to some situations of risk. The effects described as beneficial are emotional stability and memory consolidation (Mantua & Spencer ). Regarding the harmful effects, cognitive decline, depressive symptoms, cardiovascular and metabolic diseases can be mentioned (Abraham et al, ; Chen et al, ; Cross et al, ; Fang et al, ; Mantua & Spencer ).…”

Aim and objective To analyse the association between napping, functional capacity and satisfaction with life in older adult residing in the community. Method A cross‐sectional population‐based study using data from a health survey conducted in a city of the state of São Paulo. Information on sociodemographic and clinical variables was collected through a questionnaire, as well as the occurrence or not of napping and satisfaction with life. Functional capacity was assessed using the Katz Index and Lawton–Brody Scale. Statistical analysis was performed using the Rao–Scott chi‐square test and a hierarchical analysis using stepwise backward multiple Poisson regression. p‐Values <0.05 were considered significant. In this paper, we adhere to STrengthening the Reporting of OBservational studies in Epidemiology guidelines. Results There was predominance of the 60–69 years age group (51.3%) and of females (60.8%). The majority of the older adults (57.5%), of both sexes, reported napping. A higher prevalence of napping was found in the older subjects, the male sex, the subjects without children, those with health problems and those that were partially dependent in instrumental activities of daily living. Conclusions The study showed that naps are prevalent in older adults. The need to identify the issues that permeate napping is emphasised, in order to promote health in individuals of this age group, before classifying the practice as beneficial or harmful. Relevance to clinical practice It is essential that health professionals, in their practices, consider the complaints and reports of naps in the elderly, in an attempt to detect and reduce possible consequences in activities of daily living.

“…However, epidemiological investigations reached controversial conclusions 1 . For instance, some studies have demonstrated that a midday nap could enhance immune system by restoring the neutrophil count to baseline values 2 , reduce the risk of hypertension and metabolic diseases 3 4 and improve alertness, learning capacity and mental health [5][6][7][8][9] , while others found that daytime napping could increase the risks of diabetes mellitus [10][11][12] , hypertension and cardiovascular events 13 14 , obesity 15 and cognitive impairment [16][17][18] . One of the main reasons underlying these contradictory conclusions is the difficulty in determining the causal role of daytime napping in human health and disease.…”

Background: It remains controversial whether daytime napping is beneficial for human health. Objective: To examine the causal relationship between daytime napping and the risk for various human diseases. Design: Phenotype-wide Mendelian randomization study. Setting Non-UK Biobank cohorts reported in published genome-wide association studies (GWAS) provided the outcome phenotypes in the discovery stage. The UK Biobank cohort provided the outcome phenotypes in the validation stage. Participants: The UK Biobank GWAS included 361,194 European-ancestry residents in the UK. Non-UKBB GWAS included various numbers of participants. Exposure: Self-reported daytime napping frequency. Main outcome measure: A wide-spectrum of human health outcomes including obesity, major depressive disorder, and high cholesterol. Methods: We examined the causal relationship between daytime napping frequency in the UK Biobank as exposure and a panel of 1,146 health outcomes reported in genome-wide association studies (GWAS), using a two-sample Mendelian randomization analysis. The significant findings were further validated in the UK Biobank health outcomes of 4,203 human traits and diseases. The causal effects were estimated using a fixed-effects inverse variance weighted model. MR-Egger intercept test was applied to detect horizontal pleiotropy, along with Cochran's Q test to assess heterogeneity among the causal effects of IVs. Findings: There were significant causal relationships between daytime napping frequency and a wide spectrum of human health outcomes. In particular, we validated that frequent daytime napping increased the risks of major depressive disorder, obesity and abnormal lipid profile. Interpretation: The current study showed that frequent daytime napping mainly had adverse impacts on physical and mental health. Cautions should be taken for health recommendations on daytime napping. Further studies are necessary to precisely define the best daytime napping strategies.
