Researchers find full moon ‘disturbs body’s sleeping rhythms’

July 26, 2013HEALTH Researchers found evidence of a “lunar influence” in a study of 33 volunteers sleeping in tightly controlled laboratory conditions. When the Moon was round, the volunteers took longer to nod off and had poorer quality sleep, despite being shut in a darkened room, Current Biology reports. They also had a dip in levels of a hormone called melatonin that is linked to natural-body clock cycles. When it is dark, the body makes more melatonin. And it produces less when it is light. Being exposed to bright lights in the evening or too little light during the day can disrupt the body’s normal melatonin cycles. But the work in Current Biology, by Prof Christian Cajochen and colleagues from Basel University in Switzerland, suggests the Moon’s effects may be unrelated to its brightness. The volunteers were unaware of the purpose of the study and could not see the Moon from their beds in the researchers’ sleep lab. They each spent two separate nights at the lab under close observation. Findings revealed that around the full Moon, brain activity related to deep sleep dropped by nearly a third. Melatonin levels also dipped. The volunteers also took five minutes longer to fall asleep and slept for 20 minutes less when there was a full Moon. Prof 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.” Some people may be exquisitely sensitive to the Moon, say the researchers. Their study did not originally set out to investigate a lunar effect. The researchers had the idea of doing the lunar analysis years later, while chatting over a few drinks. They went back to their old data and factored in whether or not there had been a full Moon on the nights the volunteers had slept in their lab. UK sleep expert Dr Neil Stanley said, nonetheless, the small study appeared to have significant findings. “There is such a strong cultural story around the full Moon that it would not be surprising if it has an effect. It’s one of these folk things that you would suspect has a germ of truth. It’s up to science now to find out what’s the cause of why we might sleep differently when there’s a full Moon.” –BBC

    The moon has a pull on water ( tides ) and what are we (Humans) made of, a large % of water so of cause its going to have effect us.
    I found your webpage about 2 years ago.
    This is the first time I have made a comment , You’re doing a great job and you have woken me up, the last two years have been very interesting !
    lots of Love.

    I wonder how much money was spent on this scientific study? All they had to do was ask nurses working the night shift. I worked ICU/CCU and definitely saw the difference, especially in geriatrics, and also in the types of patients admitted. There were more with psychotic/psychiatric disorders. The OB nurses always swore there were more babies born then, too.


  3. FULL MOON MADNESS the science is very old and profound. All institutions from Corrections to Mentally ill ALL employees on duty during Full Moon effects · days of Irritations Full Moon is a direct Reflection of the SUN.In the past 10 years on Full Moon that I have observed, Violence goes up average of 30% and 40% in existing Wars. Never get into an arguments on the Full Moon. No decisions made on Full Moon.


  4. Google Peter Knopfler American Chronicle “Full Moon Madness”. I wrote this in 2007 but this past recent Full Moon, says it again.

    The moon will turn blood-red in 2014 and 2015. Just like in 1967 and 1948.
    4 total lunar eclipses and 1 total solar eclipse.

    God bless you !!!
