the Lunar Cycle sunspots and the frequency of births in germany 1920 1989
Economics and Human Biology, 2013Co-Authors: Thomas K. Bauer, Stefan Bender, Jörg Heining, Christoph M. SchmidtAbstract:Based on multivariate linear regression models, we analyze the effect of the Lunar Cycle and the number of sunspots occurring on a particular day on the number of births using social security data and controlling for a number of other potential confounders. The daily numbers of births between 1920 and 1989 have been calculated from the full sample of individuals who have been registered at least once in the German social security system. While the Lunar Cycle does not affect the number of births, the number of sunspots is positively correlated to the number of births. The empirical results may be explained by medical technological progress making natural influences on births less important over time. This interpretation is supported by the results on the intertemporal influence of weekends and holidays on the frequency of daily births.

Brother Sun, Sister Moon: The Lunar Cycle, Sunspots and the Frequency of Births
SSRN Electronic Journal, 2010Co-Authors: Thomas K. Bauer, Stefan Bender, Jörg Heining, Christoph M. SchmidtAbstract:Based on multivariate linear regression models, we analyze the effect of the Lunar Cycle and the number of sunspots occurring on a particular day on the number of births using social security data and controlling for a number of other potential confounders. The daily number of births between 1920 and 1989 have been calculated from the full sample of individuals who have been registered at least once in the German social security system. While the Lunar Cycle does not affect the number of births, the number of sunspots has a positive, albeit small effect on the number of births which is decreasing over time. The empirical results may be explained by medical technological progress making natural influences on births less important over time. This interpretation is supported by the results on the intertemporal influence of weekends and holidays on the frequency of daily births.

The Lunar Cycle affects at-sea behaviour in a pelagic seabird, the streaked shearwater, Calonectris leucomelas
Animal Behaviour, 2008Co-Authors: Takashi Yamamoto, Akinori Takahashi, Ken Yoda, Nobuhiro Katsumata, Shinichi Watanabe, Katsufumi Sato, Philip N. TrathanAbstract:The Lunar Cycle has been shown to affect the behaviour of a variety of marine animals. However, changes in the behaviour of seabirds and marine mammals and how they respond to the Lunar Cycle have been less well documented, principally because of the technical difficulties in long-term recording of their at-sea behaviour. Because seabirds generally rely on visual cues at small spatial scales, ambient light levels by moonlight may have a strong influence on their foraging and predator avoidance behaviours at sea at night. We used global location sensor loggers attached to wintering streaked shearwaters to examine whether the birds' at-sea behaviour varied with the Lunar phase. The shearwaters migrated from Japan to the seas off northern New Guinea. Their activities at night changed synchronously with the Lunar phase: birds flew for longer periods and landed on water more frequently on nights with a full moon than when there was a new moon. Our results indicate that at-sea behaviour of pelagic seabirds is closely associated with the Lunar Cycle.

moonstruck the effect of the Lunar Cycle on seizures
Epilepsy & Behavior, 2008Co-Authors: Sallie Baxendale, Jennifer FisherAbstract:Recent reports on the effects of the Lunar Cycle on seizure occurrence have yielded mixed results. If the moon phase is influential, we hypothesized that this would be due to the moon’s contribution to nocturnal illumination, rather than its waxing or waning state, and that significant correlations would not be apparent if local cloud cover were controlled for. We found a significant negative correlation between the mean number of seizures and the fraction of the moon illuminated by the sun (ρ = –0.09, P < 0.05) in 1571 seizures recorded in a dedicated epilepsy inpatient unit over 341 days. This correlation disappeared when we controlled for the local clarity of the night sky, suggesting that it is the brightness of the night and the contribution the moon phase makes to nocturnal luminance, rather than the moon phase per se, that may influence the occurrence of epileptic seizures.

Revisiting an ancient legend: Influence of the Lunar Cycle on occurrence of first-ever unprovoked seizures.
Internal medicine journal, 2020Co-Authors: Shuyu Wang, Ray Boston, Nicholas Lawn, Udaya SeneviratneAbstract:The mythical effect of the Lunar Cycle on seizures has been debated over time. Previously healthy individuals presenting with first-ever seizures in whom investigations are negative often invoke questions about potential reasons including a full moon. To determine whether there is a temporal relationship between the occurrence of the first-ever unprovoked seizure and the Lunar Cycle. We studied adults who presented with a first-ever unprovoked seizure to two tertiary centres in Australia. Seizure onset time was obtained from the emergency department and ambulance documentations. We used Poisson regression modelling and incidence rate ratios (IRR) to determine whether seizures have a preponderance for a particular Lunar phase. We performed further analysis on "first seizure epilepsy" and "first seizure not epilepsy" subgroups based on the International League Against Epilepsy criteria for a diagnosis of epilepsy after a single unprovoked seizure. We analysed 1710 patients (38% females; median 39 yr), of whom 18% had epileptiform abnormalities on EEG and potentially epileptogenic lesions were detected on neuroimaging in 28%. Based on the EEG and imaging findings, 684 (40%) patients were categorized as "first seizure epilepsy" and 1026 (60%) "first seizure not epilepsy". The whole cohort and subgroup analysis demonstrated no significant difference in the seizure occurrence among the four Lunar quarters. First unprovoked seizures are not influenced by the Lunar Cycle. Patients pondering the cause of their first-ever unprovoked seizure can be reassured that the full moon was not responsible. This article is protected by copyright. All rights reserved.
