SAD αλήθεια?!? SAD!!! Seasonal affective disorder (SAD) is a type of depression that affects millions during the winter, when daylight hours are shorter. It is not well-known what exactly the lack of natural sunlight does to the brain, but it could lead to decreased levels of serotonin or interrupt circadian rhythms. Though a specific mechanism for this study was not identified, it is possible that factors that may affect a pregnant mother during seasonal changes could get passed down to the developing fetus.
