Edition BBC reports that 33 volunteers participated in the test, which would determine how lunar cycles affect the sleep patterns of a person. Tests have shown that most of the volunteers were experienced problems with sleep during the full moon. During this period they needed more time to sleep and periodically waking up during the night. Thus, they fell asleep 5 minutes later and slept for 20 minutes less.
Christian Cajochen Professor at the University of Basel has put forward his own theory that during the full moon changes the degree of brightness of the moon, and causing sleep disturbance. However, the fact that the testing was carried out in strict laboratory conditions: dark rooms, without Windows and in complete silence contradict its assumptions.
Scientists have proven that it is in the dark produces a hormone that regulates circadian rhythms (melatonin). But it was during the full moon in humans, melatonin levels were significantly decreased, which influenced the work of the internal clock and, however, has failed dream. Scientists say that the normal secretion of melatonin depends on the lighting, that is, the day must be enough light at night should be dark enough.
In addition, during the full moon period in humans reduced the phase of deep sleep, which is associated with brain activity, resulting in over night there is a restlessness and sleep becomes very sensitive.
