Then, as the Earth continues its path around the sun, days become shorter and nights lengthen, with the change becoming more pronounced in the higher latitudes, but remaining nonexistent at the equator. This change in the amount of light is a signal to animals, plants and, before the light bulb, people, of changing seasons.
When do suicides peak?
There is evidence of seasonal peaks in suicides, which occur more frequently in summer, and birth rates, which also tend to peak in spring and summer.
