Full Moon disturbs a good night slee

RATE THIS! +17
Posted in Science on 25th Jul, 2013 10:15 PM by AlexMuller

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.
