My whole adult life I’ve suffered from SAD (seasonal affective disorder). Years ago I got a light-therapy light, and found that I used it quite reflexively: It would pretty much stay off all summer and early fall, then one day in mid-October or so I’d turn it on without even thinking about it. Only later would I realize, “Oh, yeah. I needed that.”
This year I didn’t have the urge to turn the light on until yesterday, which is several weeks later than typical in recent years.
This morning, while out walking the dog, I realized why it was so much later: I’m out walking the dog close to sunrise nearly ever day.
And, as everyone knows (if they think about it), the best light-therapy light is the sun.
Highly recommended: Get outdoors while the sun is still low in the sky. Get yourself some light, along with some vitamin N (nature), and some outdorphins.,\
That’s why I open the blinds as soon as I get up so I won’t miss the morning sun even if I don’t get out. I should get out for sunrise more often though.
