Some evidence for the person that is in favor of this idea. I know i'm more cranky towards, well everyone, when I don't get much sleep. (Taken from wiki)
Sleep quality
A July 2013 study carried out at the
University of Basel in
Switzerland suggests a correlation between the full moon and human sleep quality.Professor Cajochen and colleagues presented evidence that a lunar rhythm can modulate sleep structure in humans when measured under the highly controlled conditions of a circadian laboratory study protocol without time cues. Studying 33 volunteer subjects, the researchers found that subjective and objective measures of sleep varied according to lunar phase and thus may reflect human circalunar rhythmicity. Stringently controlled laboratory conditions, in a cross-sectional setting, were employed to exclude confounding effects such as increased light at night or the potential bias in perception. Measures of lunar influence on sleep structure,
electroencephalographic activity during
non-rapid eye movement sleep (NREM), and secretion of the hormones
melatonin and
cortisol, were retrospectively analyzed. At no point, during and after the study, were volunteers or investigators aware of the posteriori analysis relative to lunar phase. Around full moon it was found that electroencephalogram (EEG) delta activity during NREM sleep, an indicator of deep sleep, decreased by 30%, time to fall asleep increased by five minutes, and EEG-assessed total sleep duration was reduced by 20 minutes. These changes were associated with a decrease in subjective sleep quality and diminished endogenous melatonin levels. Cajochen said: "The lunar cycle seems to influence human sleep, even when one does not 'see' the Moon and is not aware of the actual moon phase."
