- cube2222 3y agoand/or eat a lot of food rich in Vitamin D.
- hatsunearu 3y ago30 minutes in the sun is enough to get your daily dose iirc. I think I get 30 minutes from going outside for lunch and walking to my car, driving, taking out the trash, getting my mail, etc.
- basisword 3y agoI’m not sure how correct that is. Particularly in certain countries and especially in winter. I get out for more than 30mins every day and my levels are deficient when I tested.
- bqmjjx0kac 3y agoIt also depends on your skin color and latitude.
- jgalt212 3y agoit varies greatly person to person.
- itake 3y ago+1. I was deficient, despite averaging 7000 steps per day (80 min of walking). I also live in seattle and stay bundled up
- PartiallyTyped 3y agoCopenhagen in the winter will have you sit outside all day. All 6 hours of it.
- jessicas_rabbit 3y agoIn order to produce vitamin D, your skin needs continuous time in the sun to fully react with sunlight. 30 minutes of continuous chemical reaction will have vastly different effect than a reaction that stops & starts repeatedly, for a sum total of 30 minutes.
- cyberax 3y agoYou actually are going to synthesize _more_ vitamin D if you do fractionated exposure. That's because vitamin D synthesis is an equilibrium reaction, UV drives backward and forward reactions. So you'll get more vitamin D if you expose your skin to the sun for a few minutes, then let the synthesized vitamin to diffuse out of the skin layer, and then expose yourself again.
- jessicas_rabbit 3y agoThat makes sense. Thanks for explaining.
- gadflyinyoureye 3y ago30 minutes with large skin contact. Take off your shirt or have a tank top.
- gtirloni 3y agoThat's enough for skin cancer where I live. 5min tops.
- ycombinete 3y agoI guess that depends on time of day, and ozone health, I assume you live in Australia? I live in the Middle East and the uv index in the am (before 9am) in direct sunlight isn’t that crazy.
- smilespray 3y agoIt's enough for frostbite where I live.
- panxyh 3y agoIt’s enough for mosquitoes where I live.
- siftrics 3y agoNot trying to argue; just chipping in: I regularly sit outside with my shirt off in ~20F weather and don't get cold enough to have to go inside. Direct sunlight makes all the difference. With the sun, sub freezing air temperatures can actually leave you feeling quite warm.
- qingcharles 3y agoI was locked in a windowless room for 10 year straight. What I don't know is if the long-term deprivation of vitamin D produces any long-term nonreversible damage. Does anyone know?
- osigurdson 3y agoThis is one thing I think is not appreciated enough about WFH. It can, in some cases mean work from outdoors for some period of time. I don’t mean relaxing in the sunshine and pretending to work. I mean working your ass off outside and moving the needle for your organization. I’m sorry, Elon is waaay smarter and more capable than I am but he is empirically wrong about his anti WFH bias.
- Zachsa999 3y agoWFH what?
- arcanemachiner 3y ago"Work from home"
- GolfPopper 3y agoOut of curiosity, and if you don't mind sharing, what was your staring position? I ask, because even if they never invest a cent in your personal ventures, it is a very significant boost to to have wealthy parents who provide both broad access to formal and informal education, valuable networking, and a dependable safety net. Saying someone with those advantages is "more capable" when comparing them to the average First Worlder (let alone the average human being) is a sort of perceptual bias that seems unfortunately common.
- osigurdson 3y agoI have no excuses.
- screwturner68 3y ago
- mLuby 3y agoIf my laptop screen were legible in direct sun, I'd be out there. Wifi and headphones. Sadly the laptop's too small and Chrome's too power-hungry for solar power to be an option: ⅓m width * ¼m length * 158W/m2 solar = 13W out of 67W to run it, or 19%.
- itake 3y agoHow do you factor in skin cancer with this mindset? While I love being outside, I always wear hats, hoods and jackets to protect my skin. Also cataracts would also be a problem.
- cubefox 3y agoI wonder what stone age people did about skin cancer. Nothing, I assume.
- CubsFan1060 3y agoI don’t think they lived long enough for it to be a problem.
- cubefox 3y agoThey were a lot longer outside than modern people though.
- antisthenes 3y agoOutside != full sun. Sitting in tree shade won't give you skin cancer.
- insanitybit 3y agoHow much UVA/UVB gets filtered out from shade under a tree? And how much vitamin D are we getting to make sitting in the shade worthwhile?
- odiroot 3y agoSo the advice to "touch grass" was actually well intentioned?
- janejeon 3y agoI'm actually rather annoyed by the recent trend of basic things like "go touch grass" or "go exercise every day" or "eat more fiber" being scientifically validated, because it's stripping away any and all excuses for me not going outside/exercising/eating well/etc. Like damn, I knew I was supposed to do such things already, but it's the difference between mom saying to eat your veggies vs. mom slamming down a stack of scientific paper about why not eating veggies will literally kill you or whatever.
- insanitybit 3y agoIf it helps, you can just take a vitamin D supplement and stay inside, avoiding some major health risks like skin cancer and death by vehicular accidents.
- manmal 3y agoSunlight does way more than let the skin convert this specific chemical. You could look up photobiomodulation, for example.
- insanitybit 3y agoSure, get a sun lamp.
- Llamamoe 3y agoGet an under-desk elliptical, vit D oil drops, bake bread with 50% wheat flour replaced with almond/coconut/sunflower/pumpkin/etc meal. Wham, unhealthy lifestyle eradicated at almost no behavioural cost.
- bawolff 3y ago[flagged]
- photochemsyn 3y agoOr, install some full-spectrum daylight-mimicing LED lights. These are not that easy to find, you want to use the CCT and CRI ratings to match sunlight as closely as possible. https://www.uvm.edu/news/extension/tips-choosing-grow-lights https://www.uvm.edu/news/extension/tips-choosing-grow-lights They're kind of hard to find, the optimal values are 6500K for CCT and as close to 100 as possible for CRI, which matches the peak value and the overall spectrum of natural sunlight. One option appears to be the NorthLux™ 95 CRI T8 LED Tube (kind of pricy though, and will need a specialized ballast fixture, also a bit pricy).
- cyberax 3y agoVitamin D needs UV, not just light. You _can_ install UV diodes, but then you have a whole another can of worms. A point source of UV can damage eyes much more easily, and if you forget to turn it off, you can expect a nasty sunburn.
- rocket_surgeron 3y agoBeing outdoors is almost always better than being indoors and people do need to get out more but that’s not the solution to a problem brought about by bodies being adapted to sub-Saharan latitudes but living north or south of the 37th parallel. https://www.health.harvard.edu/staying-healthy/time-for-more-vitamin-d https://www.health.harvard.edu/staying-healthy/time-for-more... An hour a day buck-ass naked, isn’t enough if you don’t live along the equator. For many northern and southern latitudes where many people live if you affixed yourself to a rotating pole and rotisserie’d yourself from sunrise to sunset while naked every day, then for 4-9 months out of the year you would be D deficient. I’m outdoors more than most and if I don’t supplement my levels fall into the mid-20s ng/mL, below the standard range of 30-100. And no matter how many millions of studies repeat verbatim the importance of vitamin d people still neglect it.
- lost_tourist 3y agoNo but you should go out a couple of times a week for a walk and get some sun. the body is amazingly good at manufacturing vitamin d in a short amount of time especially with full sunlight. You don't have to get skin cancer though.
- tempfortwitt90 3y agoI know several women that go outside and take walks for their vitamin d, but slather on sunscreen which blocks the process. No matter how many times I tell them it's a worthy trade-off, they won't go outside without. I'm 38, and have never worn sunscreen outside of going to the beach for a whole day. I often get compliments from women about my face, and they're shocked to hear I never wear sunscreen or moisturize. It's almost like not putting chemicals on your face is good for you.
