If you’re prone to depression during the darker months of the year, you’re probably aware of — or diagnosed with — Seasonal Affective Disorder (SAD), a mood disorder that comes and goes or worsens with the seasons. You may also have heard that SAD “doesn’t exist,” which can be a frustrating thing to hear when you’re in the midst of it.
Thankfully, SciShow Psych is here with an up-to-date look at the science of SAD, including both the research that supports its existence and the research that doesn’t. As with most scientific questions, the answers aren’t clear cut. We can be certain of one thing, though: taking care of your mental health is what matters, regardless of what studies conclude about the details.
