Sun lamp, Vitamin D etc. all help. As you mentioned, hanging out in brightly lit areas where there are people around also help. For me one component of SAD is isolation. When I was living in big northern cities where there were people out on the streets all the time and stuff to do, I was never affected by SAD. Deep winter? No problem. Now that I live in a suburb in a region of introverts, I feel SAD in spades. I’m an introvert but that’s a bit different from being a loner — I need people around me even if I don’t interact with them. So I go into the office instead of WFH. No many people there so I chat with the janitors and admin staff. Even this little bit of human interaction makes a difference for me. Your emotional well being apart from the weather matters and will either compound SAD or attenuate it.
