Efek bulan adalah sebuah dugaan korelasi yang tak terbukti antara tahap-tahap spesifik dari siklus bulan selama sekitar 29.5 hari dan perubahan perilaku dan psikologi pada makhluk-makhluk hidup di Bumi, termasuk manusia. Dalam beberapa kasus, dugaan efek dapat tergantung pada dugaan-dugaan luar, seperti sinar bulan. Dalam kasus lain, seperti perkiraan siklus bulanan menstruasi pada manusia (namun bukan mamalia lainnya), pertepatan dari waktu tak merefleksikan pengaruh bulan yang diketahui.
Sejumlah kajian menguji efek tersebut pada manusia. Pada akhir 1980an, terdapat setidaknya 40 kajian yang diterbitkan soal hubungan bulan-kegilaan,[1] dan setidaknya 20 kajian yang diterbitkan soal hubungan bulan-tingkat kelahiran.[2] Ini membolehkan beberapa ulasan sastra ekstensif dan meta-analisis dibuat, yang tak menemukan korelasi antara siklus bulan dan biologi atau perilaku manusia.[1][2][3][4]

In birds, the daily variations in melatonin and corticosterone disappear during full-moon days. The lunar cycle also exerts effects on laboratory rats with regard to taste sensitivity and the ultrastructure of pineal gland cells. Cyclic variations related to the moon's phases in the magnitude of the humoral immune response of mice to polivinylpyrrolidone and sheep erythrocytes were also described. It is suggested that melatonin and endogenous steroids may mediate the described cyclic alterations of physiological processes. The release of neurohormones may be triggered by the electromagnetic radiation and/or the gravitational pull of the moon
