I need a t-shirt that says “I went outdoors to treat my depression and all I got was this mild tan.” One of the efforts I started last year to combat my feelings of isolation and worsening depression was to make sure that I take daily walks. I didn’t really expect it to solve all my problems, but I did hope that it would have a more marked improvement on my mood and general mental health. The daily walks sure help me make sure I can get my average of six hours of sleep per night, but the emotional benefits of getting daily sunlight or daily fresh air have largely vanished at this point.
