“…Because cardiovascular and cerebrovascular events cluster after wakening from night sleep, while changes from nocturnal baseline are maximal, a second peak of such events after an additional sleep period during the day could be hypothesized. Such an association of siesta with an increased risk of myocardial infarction and higher mortality risk due to cardiovascular events, as well as an effect of siesta on parameters of cardiac structure have recently been suggested [32, 33, 34]. To our knowledge, there is no other study directly indicating a relation between siesta and a second temporal peak of stroke occurrence.…”

Two-Peak Temporal Distribution of Stroke Onset in Greek Patients

et al. 2003

A circadian distribution with a single peak of stroke onset in the morning hours has been described in various countries. Analysis of the temporal pattern of symptom onset in a series of 1,253 Greek first-ever stroke patients revealed a circadian distribution with two incidence peaks between 08.00 and 10.00 h, and between 16.00 and 18.00 h. Considering the different etiopathogenic types of stroke, the same two-peak time pattern was evaluated in all stroke subgroups with the only exception of lacunar stroke, which seems to predominantly occur during night and sleep. A secondary stroke onset peak in the late afternoon has not been previously described in such detail. A relation between the second, however lower, frequency peak and the traditional Greek habit of afternoon sleep (siesta) could be assumed and deserves further investigation.

“…However, in older people, habitual napping may be a risk factor for morbidity and mortality. Bursztyn et al [22] found that the mortality in 70-year-old Jerusalem residents who were in the habit of taking a daytime nap was twice as high as that in residents who were non-nappers, independent of other factors. Many previous cross-sectional studies found an association between day napping and diabetes in elderly populations (>50 years).…”

ContextBoth longer habitual day napping and Non-Alcoholic Fatty Liver Disease (NAFLD) are associated with diabetes and inflammation, but the association between day napping and NAFLD remains unexplored.ObjectiveTo investigate the association between the duration of habitual day napping and NAFLD in an elderly Chinese population and to gain insight into the role of inflammatory cytokines in this association.Design and SettingWe conducted a series of cross-sectional studies of the community population in Chongqing, China, from 2011 to 2012.ParticipantsAmong 6998 participants aged 40 to 75 years, 6438 eligible participants were included in the first study and analyzed to observe the association between day napping duration and NAFLD. In a separate study, 80 non-nappers and 90 nappers were selected to identify the role of inflammatory cytokines in this association. Logistic regression models were used to examine the odds ratios (ORs) of day nap duration with NAFLD.ResultsDay nappers had a significantly higher prevalence of NAFLD (P<0.001). Longer day napping duration was associated in a dose-dependent manner with NAFLD (P trend <0.001). After adjustment for potential confounders, the ORs were 1.67 (95% CI 1.13–2.46) for those reporting 0.5–1 h and 1.49 (95% CI 1.01–2.19) for those reporting >1 h of day napping compared with individuals who did not take day naps (all P<0.05). Longer-duration day nappers had higher levels of IL-6 and progranulin (PGRN) but lower levels of Secreted frizzled-related protein-5 (SFRP5, all P trend <0.001). After adjusting for IL-6, PGRN, and SFRP5, the association between day napping duration and NAFLD disappeared (all P>0.05).ConclusionLonger day napping duration is associated with a higher prevalence of NAFLD, and inflammatory cytokines may be an essential link between day napping and NAFLD.

Self-Awakening Prevents Acute Rise in Blood Pressure and Heart Rate at the Time of Awakening in Elderly People

et al. 2005

Self-awakening, waking up at a designated time decided before sleeping, could prevent failure in the blood circulation vessel system such as heart attack, acute increases in heart rate or blood pressure upon waking. Previous research showed that anticipatory changes occurred in heart rate prior to awakening from a short nap by means of self-awakening for young participants. However, the effects of self-awakening remained unclear for elderly people. The present study examined the effects of self-awakening on heart rate and blood pressure in a short afternoon nap (20 min) among the elderly. Nine participants [74.1 (SD = 5.01) years old] underwent both self-awakening and forced-awakening conditions. In the self-awakening condition, it was revealed that blood pressure gradually increased before the scheduled time of awakening, and that heart rate did not show a rapid increase at arousal. In contrast, forced-awakening induced acute increases in both heart rate and blood pressure. These results suggest that self-awakening facilitates a more smooth transition from sleep to wakefulness via autonomic activation before the time of self-awakening.
