If dark nights can treat mania, can too much sunshine destabilize it? Yes and no. Mania is linked to rapid changes in sunlight, but not to the amount of light itself. Mania peaks in early spring when there’s a steep rise in sunlight. By the time the longest day of the year comes along in late June, there’s no longer a detectable increase in mania (Parker G et al, J Affect Disord 2018;226:72–76).
