A lack of sunlight is thought to be one of the biggest contributors to seasonal depression. That's why Dr. Siddle recommends using a light box during these darker months. "To me, it feels a little bit like therapy," she told POPSUGAR. Dr. Seymour agreed, noting that students should look for a light box that filters out UV light, while delivering 10,000 lux of light (the standard recommendation).
If light therapy products are out of your budget, you can also make changes to your daily routine so that you're maximising the amount of daylight in your schedule, Dr. Seymour explained. Other ideas include shopping for brighter, full-spectrum light bulbs, or rearranging your dorm so that more light can get in.
