Daylight saving time was not associated with a change in suicide rates in Austria, Switzerland and Sweden

Background: Some studies have reported an increase in suicides after the start of daylight saving time (DST), but the evidence is mixed and more research about proposed mechanisms (disrupted sleep, changing light exposure) is needed. Methods: In our preregistered study, we analyzed change in suicide rates in the 2 weeks before/after DST, based on data between 1980 […]

Daylight saving time is causing suicide

This paper seeks to verify whether an abrupt change in exposure time to solar luminosity affects suicide incidence. The article is based on the medical and psychiatric literature suggesting that this climate variable seems to affect reported cases of suicide worldwide. Methodologically, data relating to mortality in Southern Brazil were used over a period of […]
