MONTREAL (CBSDC) – Full moon or no full moon, its presence doesn’t affect whether people get a little stranger than usual.

A three-year study from a group of Canadian researchers has used the lunar calendar to conclude that individuals who wound up in hospitals with undetermined medical causes did not wind up there because of a full moon.

The research looked at 771 patients who spent time in emergency rooms at Montreal’s Sacré-Coeur Hospital and Hôtel-Dieu de Lévis between March 2005 and April 2008, according to the Toronto Star. The study, recently published in General Hospital Psychiatry, found that the 771 patients who entered emergency rooms with undetermined medical causes had long medical histories, filled with past instances of panic attacks, suicidal thoughts, and anxiety and mood disorders.

“If you still want to believe it, go ahead,” Genevieve Bellville, lead researcher of the study from Laval University’s School of Psychology, told the Toronto Star recently of the long-held full-moon theory. ”It’s not my job as a scientist to convince … it’s my job to check the facts.”

When the patients were matched up with the lunar calendar, Bellville and her staff found that there was no relationship between strange things happening while there is a full moon.

“One thing is certain: We observed no full-moon or new-moon effect on psychological problems,” Bellville told the Star.
