I am planning to buy some compact fluorescent bulbs to emulate the more full light spectrum of daylight indoors. However, I need some additional sockets to put the bulbs into. Would anyone know the name of something like a power cord with a plug... (more)

I use this Ikea light cord, with a super bright CFL bulb, plugged into a timer so that it comes on automatically in the morning. The bulb is a "daylight balanced" ALZO 45W 2800 Lumens (I got mine from Amazon). It's almost three times larger than a... (more)

Can you get vitamin D from being outside (in relative shade?) with indirect sunlight? I am sure it would be a fraction of direct sunlight exposure, but I was wondering if there was any significant vitamin d we can get from indirect sunlight. (more)

Not much, unfortunately. If the UV index outside is let's say at 5, then the UV index in shade will be...lower (I don't recall how much lower, but it's much lower). Combine that with the decreased per-unit of skin area production of vitamin D in... (more)

I think the important thing is to use real olive oil, in other words the expensive stuff. Make sure it passes the fridge test (it should get slushy after four or five days in the fridge). Most mainstream OOs don't. I tried three or four, and none... (more)
