Interesting.
Anecdotal evidence to the contrary - i have a sunshine-bright light fixture at home (600W worth of metal halide arc lamps), and while it does make the dull winter days less dark and gray, it also tend to make me tire quicker.
It's the same sort of feeling you get when you haven't slept in a while after having slept too much - your brain still feel fine, but your eyes are already tired (and yes, i checked the lamps for a lack of UV).
Perhaps it is a question of a dose...
- moron4hire 10y agoI would not say my sunshine light makes me tire quicker. I would say that the dim light of my house--lit through shades and by computer monitors--breaks my circadian rhythm, suppresses my natural "tired" signals, and keeps me up later than I should be.
- david-given 10y agoWhat sort of lamps do you have? Metal halide colour temperatures vary enormously --- from sunlight at about 6000K way down to about 3000K. That'll be way redder than real daylight, and may not have the right effect.
- Artlav 10y ago4200K - nice sunset/sunrise kind of light. And yeah, from what i heard it's the blue light that have the most effect in light therapy.
