If a faint light from under a door is able tu suppress melatonin, does this mean utilities such as f.lux are completely useless?
- david_shaw 12y agoThat does seem amazingly sensitive, but still -- if faint light from under the door (partially?) suppresses melatonin, I would imagine that a 27" monitor would do so significantly more.
- carlob 12y agoYeah, but if we are sensitive to light from under a door with our eyes closed it seems that just changing the hue will have little effect.
- jules 12y agoThat would be surprising since ancient humans didn't sleep in total darkness either; they got light from the moon and stars.
- sanoli 12y agoI though the same thing. Anyone who's ever been camping with no other light source other than a full moon will remember how much light (I guess is it's pretty blueish?) the moon puts out. But, maybe it's not too much, since our eyes are probably very night-adapted when there's no other light source?
- lawlessone 12y agof.lux probably isn't meant for use while you're actually asleep.

I found f.lux only a little helpful -- it wasn't until I added blackout curtains and started wearing blue-blocking glasses at night around the house that I noticed a strong effect. Glasses are super annoying to wear though.
