In Shape Today
Stop procrastinating and begin your healthy life today!
Cold is good.
Don't watch Rogan, but yes. Cold is pretty good
I got a really bad cold from a cold shower.
that means you are weak anon. wtf
Unironically something is wrong with your immune system.
Sounds like a you problem, anon.
It's the opposite for me
If I stop with cold showers my immune system turns to shit
>cold water infected me with a virus
to think you were the strongest sperm of your lot
I hot then freezing cold shower right before I workout, that with coffee is my preworkout
So what am I supposed to do, get cold, then spend 20-30 minutes warming up? Sounds like a recipe for injury.
cold showers suck, cold baths are cool huehuehue
It's winter so I just sit outside in nothing but a pair of shorts and soak up sun until I can't stand it anymore. Keeps my vit D levels up AND gets all those sweet cold benefits.
Depending on your latitude you cannot produce vitamin D during winter. Even below that latitude, the quantity produced is dramatically attenuated.
Never knew the sun was such a garden gnome
Some is still better than none. And I think the placement of that line depends quite a bit on your race and skin color. It's thought that that's the primary reason whites evolved to be white, to get more Vitamin D from the sun at higher latitudes.
I suspect that line on the map is for darker skinned people.
Just read the fucking text on the page you ADHD moron
I did, gay. Is there something I missed? They mentioned skin color in a few places but none of it is relevant to the map, because that line should be in different places for different races. All they basically said is that vitamin D deficiency is common in winter and double common among blacks in general.
Shut the fuck up, and maybe use that quiet time to read the link yourself, dumb bitch. Fuck you.
>Except during the summer months, the skin makes little if any vitamin D from the sun at latitudes above 37 degrees north
That's the sentence. The line doesn't shift based on your skin colour, UVB intensity is a function of the angle of the sun through the atmosphere. You can have no melanin at all and still not produce vitamin D because the UVB is NOT THERE
You're posting like a redditor where every question you asked is discussed in the article but you needed to make a response where you contribute nothing.
Maybe a better link here:
They measure UVB availability relative to latitude, and how that correlates with Vit D levels in people. They use a threshold UVB level of 1000 Jm−2
>In the present work, a threshold of 1000 Jm−2 was used as a guide to a UVB dose below which dermal synthesis of pre-vitamin D3 will be relatively low. Of importance, it should not be viewed as an empirical UVB dose below which dermal synthesis of pre-vitamin D3 is comprised, but rather reflects a dose which is only likely to lead to minimal increases in average monthly serum 25(OH)D (i.e., <1.5 nmol/L) during winter. This was based on our previous modeling of the direct impact of UVB on population serum 25(OH) D . It is also in line with the older data from Webb et al.  who, using human skin or [3α-3H]7-dehydrocholesterol in a model system exposed to sunlight, showed that pre-vitamin D3 was not produced for 4 and 6 months of winter at 42° N and 52° N, respectively.
Good enough for me. Figure out your latitude and then do some research to determine which months are actually viable. Regardless, sitting out in the shorts in the cold is pretty awesome and builds spiritual strength regardless. of Vit D, but you'll probably want to supplement for 3-6 months of each year.
Yeah, supplementation is still a good idea in the winter, but you can still get a fair bit from the sun. You just have to show some skin, and it takes longer, but it is still possible.
Fuck you gay, you said it was useless, and then backpedaled to just MOSTLY useless. Disingenuous piece of shit. Go find some more articles that make you feel better for being a weak bitch
>tfw haven't seen the sun in weeks
There was a single spot of blue in the impenetrable cloud barrier the other day. That was cool
This crop looked familiar
