The onslaught of fall brings a handful of upsides. Instagram-friendly foliage, the overly hyped PSL (sorry, not sorry) and a closer proximity to the holidays. But as summer bids us a bitter farewell, it can also bring on a kind of depression. And we don鈥檛 mean that in the 鈥渘o more summer Fridays鈥 kind of way. Sometimes the shift in seasons can cause Seasonal Affected Disorder (SAD for short).

Natasha Bhuyan, MD at聽One Medical explains, 鈥淚t鈥檚 a type of depression that follows a pattern. People mostly get it in the late fall through winter and feel better in summer months. Then it returns again the following year.聽A lot of times it鈥檚 confused with traditional depression.鈥

SAD was only recognized聽as a disorder in 1984. It鈥檚 often confused for traditional聽depression because they have most of the same symptoms:聽not feeling interested in what you used to be interested in, tiredness, difficulty getting out of bed, etc. But SAD鈥檚 differentiation comes in its repeat offense. If you can recall something similar happening for the last couple of years, that鈥檚 usually a good indication. It can also be a genetic thing, so look into your family history.

Bhuyan explains that the cause still isn鈥檛 entirely clear. 鈥淒octors don鈥檛 really know exactly what the cause is, but they think it鈥檚 light-related. People who live further from the equator are more prone to SAD, whereas people who are living in sunny areas don鈥檛 see as many cases.聽It could also be connected to the circadian rhythm聽when it gets lighter earlier. It causes you to make more melatonin, which causes drowsiness.鈥

The cure? Simple. More light. While traditional depression is often treated with medication, Bhuyan explains that in most cases this can be treated at home with light therapy. Bhuyan advises patients diagnosed with SAD or concerned they might have it start spending some quality time with a light box. 鈥淪it in front of a light box [a fluorescent one works] with your eyes open; don鈥檛 look into the聽light,鈥 she says. 鈥淪tart with 10 minutes a day and then move into 45. Eighty-five percent of the time it works.鈥

It helps that light boxes can easily be found online.聽One Target customer gave this HappyLight a glowing review. She writes, 鈥淏y the third day of use, I could feel a real difference. For you, it may take longer to feel results, or you may need more light [鈥 To sum it all up鈥n the ongoing fight against depression, I鈥檓 a long-time veteran, and I LIKE this product!鈥

Sometimes it鈥檚 as simple as that, and other times it can require more attention. But if you find yourself feeling down as the leaves fall, it might be worth looking into. 鈥淪o many people just write it off as winter blues,鈥 Bhuyan says. 鈥淏ut the problem is, it doesn鈥檛 get better, so we want people to reach out to their doctor.鈥
