“…However, no significant effect of the lunar cycle on the number of deliveries was found in Austria [10] and in American studies [11,12]. Several papers reported associations between the lunar cycle and the frequency of hospital admissions due to various causes: cardiovascular disease [13], acute coronary events [14], gastrointestinal hemorrhage [15] and infectious diarrhea [16]. Lunar phases were also associated with the number of requests for appointment at a thyroid outpatient clinic [17].…”

230Main text: 2938 Tables: 4 3 ABSTRACT Objectives: Popular belief holds that the lunar cycle affects human physiology, behavior and health, including sleep. To date, only a few and conflicting analyses have been published about the association between lunar phases and sleep. Our aim was to analyze the relationship between lunar phases and sleep characteristics. Methods:In this retrospective, cross-sectional analysis data from 319 patients who had been referred for sleep study were included. Individuals with apnea-hypopnea index≥15/h were excluded. Sociodemographic parameters were recorded. All participants underwent one-night standard polysomnography. Associations between lunar cycle (new moon, full moon and alternate moon) and sleep parameters were examined in unadjusted and adjusted models.Results: 57% of patients were males. Mean age for men was 45±14 years and 51±12 years for women. 224 persons had their sleep study done during alternate moon, 47 during full moon and 48 during new moon. There were no significant differences regarding age and gender between groups.Full moon was associated with lower sleep efficiency (median(%) [ Conclusion:Our results are consistent with a recent report and the widely held belief that sleep characteristics may be associated with the full moon.

“…Furthermore, it is difficult to ignore a common belief among medical professionals that moon has an impact on human health [12]. Substantial evidence suggests that lunar phases can be associated with the incidence of acute neurological and vascular disorders, including hemorrhagic stroke [8], gastrointestinal bleeding, [22], seizures [23] and myocardial infarction [24]. However, others did not find an association of moon phases with the incidence of seizures [25] and ischemic stroke [8].…”

The association between lunar phase and intracranial aneurysm rupture: Myth or reality? Own data and systematic review

BackgroundIt is a common belief in medical community that lunar phases have an impact on human health. A growing body of evidence indicates that lunar phases can predict the risk to develop acute neurological and vascular disorders. The goal of present report was to present our institution data and to perform systematic review of studies examining the association of intracranial aneurysm rupture with moon phases.MethodsWe identified all patients admitted to our department for ruptured intracranial aneurysms in a period between November, 2011 and December, 2014. Patients with a known aneurysm rupture date were included. Lunar phases were determined by dividing lunar month (29.5 days) into eight equal parts, i.e., new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. A systematic literature review was undertaken to identify studies that evaluated the association of lunar phases with the incident of intracranial aneurysm rupture.ResultOne hundred and eighty-six patients (62 men and 124 women, median age 56 years) were admitted to our department for treatment of ruptured intracranial aneurysms. The rate of intracranial aneurysm rupture was equally distributed across all phases of the lunar cycle (X 2 [7; 185] = 12.280, p = 0.092). We identified three studies that evaluated the association between incident intracranial aneurysm rupture and lunar phases with a total of 1483 patients. One study from Lebanon found that the incidence rate of intracranial aneurysm rupture was statistically significantly greater during the new moon phase (25% cases), relative to the other seven lunar phases (p < 0.001). Two subsequent studies from Austria and Germany in larger patient samples (n = 717 and n = 655, respectively) did not find an association between lunar phases and intracranial aneurysm rupture (p-values of 0.84 and 0.97, respectively). When analyzing all four studies together, we did not find an association between lunar phases and incidence of intracranial aneurysm rupture (X 2 [1668; 7] = 2.080, p = 0.955).ConclusionsMoon phases are not associated with incidence of intracranial aneurysm rupture. Studies investigating the association of intracranial aneurysm rupture with lunar illumination defined using more sensitive approaches are encouraged.

“…Since 50-60% of the human body consists of water, the physiology of blood circulation might differ when there is a full moon compared with other days of the month. Admissions to hospitals and emergency units for various cardiovascular and acute coronary events and for variceal hemorrhage have been shown to correlate with a full moon (Oomman et al, 2003;Roman et al, 2004). Those studies provided evidence to suggest that human physiology can be affected by lunar phases.…”

Since 50-60% of the human body consists of water, the physiology of blood circulation might be affected by a full moon differently than during other days of the month. This study analyzed a potential association among lunar phases, seasonal variations, and the rate of spontaneous epistaxis. Consecutive admissions solely for spontaneous epistaxis to an otolaryngology emergency room of a single medical center during 1 year were evaluated. The applied tests failed to show changes of admissions during different lunar phases. According to multiple comparisons, admissions were significantly less frequent during the summer months, similar to findings from other countries of the northern hemisphere with varying climates, suggesting an influence of circannual rhythms rather than of environmental conditions.
