International researchers in Gothenburg, Sweden, have concluded that people are more sensitive during this lunar phase and will sleep an average of 20 minutes less.
Their results match those of a Swiss study conducted last year involving 33 participants, although the two studies lock horns where REM sleep is concerned. While the Swiss study says people sleep 20 minutes less during the full moon, it also says they are likely to enjoy 30 minutes more REM sleep, the deepest phase of sleep characterised by rapid eye movements.
