Hoo boy, this insomnia is getting to me, ever since we lost the hour last weekend. I know other folks who are similarly affected. You wouldn’t think missing one hour would make such an impact, but apparently it does.
Add to that, the moon is full. I can usually count on at least one night of restless broken sleep during this phase. This month so far I tally two* nights lost.
So. While I was tossing and turning last night, I recalled a post I had read on Paul’s blog, about personality types and introverts and the like. He posted links to personality tests, so I gave it a whirl. I’m still an introvert (no surprise there.)
Then that got me thinking about Elaine Aron’s book The Highly Sensitive Person which I read in the late 1990’s. She introduced me to the concept of introversion and a heightened sensitivity to my physical environment.
Physical environment, eh? I wonder. We know that the moon is powerful enough to affect the tides. Does it affect sleep patterns? Dr. Google, what do you say?
A July 2013 study carried out at the University of Basel in Switzerland suggests a correlation between the full moon and human sleep quality. 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.”
I “rest” my case.
