Later studies have failed to find correlations between the moon and our health. An research on “lunar-lunacy” published in 1985 concluded that there was no correlation between the Moon and incidents such as crime, suicides, and mental hospital admissions. A 1988 published paper criticizes hypotheses on a “lunar-effect” in association to the human condition, by concluding that none are efficient enough to explain the alleged effects of the moon and a human's well being. Stating a lack of satisfactory mechanisms, a reliable connection between lunar periodicity and human behavior, and generally negative results obtained in other studies.
