You don't need a lot of minutes outside to get a sufficient amount of sunlight to produce Vitamin D. Maybe 15-20 min a day.

- toper-centage 5y agoIt's 0ºC here. The only exposed skin is the center of my face. I find it hard to believe 15 minutes of exposure are enough.
- ihateolives 5y ago> The only exposed skin is the center of my face. Me too. And I have a beard. Do I have to take that into account? Do bald men get more D-vitamin out of the sun? Studies never talk about hairiness.
- markdog12 5y agoI regularly go outside with my shirt off at -10C, as long as there's no wind and the sun's beaming, I'm nice and warm. Got a bit of a suntan last week. Wife thinks I'm crazy :)
- stavros 5y agoI play tennis in the Greek sun four hours a week (plus whatever other exposure) and I'm still deficient. I don't know who these levels were designed for, maybe my ancestors who were in the sun so often that they looked 50 in their thirties.
- ihateolives 5y agoWhere I live we had 14 hours of sunlight per entire January of last year. 14 hours. FOR ENTIRE MONTH. And sunrise is past 9 in the morning where entire population is already indoors working, sunset is about 3 in the afternoon. So yeah, I maybe got 15 minutes of sun for entire January, but this is my generous guess.
- sgt 5y agoSounds like you live in Canada or Northern Norway or somewhere. I would get a UV lamp or something.
- 0xcafecafe 5y agoDoesn't that vary with the skin color (aka melanin content in the skin)? I presume as a brown person I need more exposure for an equivalent dose compared to a Caucasian person.
- stjohnswarts 5y agoYes it does, darker skinned persons in northerly climes are at higher risk of lower vit D than we pale skins with the equal level of exposures to the sun.
- sgt 5y agoIt's a builtin feature of us white folks to think everyone else is also white. /s
- 0xcafecafe 5y agoHa :)
