    Vitamin D can be produced at low intensity sunlight, like a UV index of 1-2, when during summer the intensity can reach a 12 depending on where you live, which is absolutely dangerous even for minutes, unprotected. People, especially fair-skinned should use protection when UV index is above 3 or so.
    I assume people sought shelter under trees and such before civilization during periods of high intensity, usually during noon, because it's not like you can stay out very much anyway with such heat, let alone at direct sunlight.

    Well yeah, but my point was we weren't terrified of the sun, and enjoyed being outdoors.

    Is playing sports outdoors bad, too? haha, I don't know. It just seems weird to me, y'know? I know it's commonly believed, and their is proof backing it up, but I'm a little skeptical (not that the sun isn't harmful, just in it's entirety)

    You can always wear sunscreen and a hat. To be honest, even megadoses of vitamins produce harmful and undesirable side effects so it's just lots of things in moderation.

    Well, I derive quite a lot of pressure from being outdoors, so it seems kinda strange that something so natural, and has been around for so long, is completely harmful for you. It's like saying that water is bad, or oxygen is bad. It's weird.

    Isn't there proof now that SITTING on a regular basis is bad for you, and at the same time, being indoors is bad for you, too. To not do anything harmful to your health, you have to it seems be some sort of vegan monk, who sits...I mean *ahem stands all day meditating, and doing chores or something.

    *okay wait, this makes sense to me:

    "
    We (placental mammals) seem to have lost it through evolution. However, most animals, plants, and single celled organisms have photolyases (a type of enzyme that actually works with light) that can repair certain types of bonds that have been created by UV interference.
    We have other proofreading enzymes, but they aren't as effective in some cases"

    Being outdoors isn't completely bad for you. The sun is just bad if you overdo it. Humans are designed to cope with amounts of sunlight, it's just select parts we can't cope with and things like car windshields protect us almost entirely.

    Sitting though..... now THAT we weren't designed to do the way we do. Weight gain, heart problems, diabetes, back problems and atrophy can all result from spending as much time in front of screens as we do.

    As long as you're moderately active and don't lay in the sun all day without sunscreen, you likely won't encounter many harmful effects if at all.

    Well, how do you know that they weren't terrified of the sun and enjoyed being outdoors during times of high intensity like we have during summer? The rest of the year, UV index is at an acceptable range so being outdoors is generally not a problem, unless you are fair skinned. Back then people probably weren't that fair skinned but I don't know much about that.

    Oh and seeing your other post I realise I should have said it in my first response. Our bodies of course have the ability to repair damage from sun exposure, but not entirely. Wrinkles and other skin deteriorations are the "benign" result from sun exposure after years, and cancer is the worst form.

    Haha, this has just completely ruined how I view summer, though. I never spent that much time outdoors anyway (introvert) but like, I pretty much have no desire to anymore.

    And I have mixed feelings about that, I will miss parts of it, but at the same time, I will no more feel "guilty" about not spending enough time outdoors during the summer.

    I only ever liked the warmer month's in the early morning or late afternoon though, when the sunlight and heat was not too intense.

    I always knew sun tanning was bad though, and generally avoided it.

    OKAY, I have a question.

    If you want to feel good, avoid feeling low, and even*GULP* depression; does one have to exercise regularly? I used to pretty regularly. I'm still in pretty good shape, but I'm wondering if it's a bad thing or not. Most people I know don't, and I feel sort of embarrassed about it. Like when you tell people you work out and go to the gym regularly they're like *GASP* you must be really together or something and it's like, no not at all. I'm a slob.

    Also, does it make you a tool? It makes me feel like a tool, I don't know why. I don't want people to think I'm that together.

    Hahah you could go out in the morning and afternoon, avoid 11:00-16:00 and you'll be fine, maybe with a little sunscreen as well.

    Well, I've been through depression and many years of anxiety and not exercising. Now that I'm better, exercise makes me feel great and definitely improves any low mood I might have some days. And it's not even heavy exercise or anything, even walking one hour makes a big difference and I kinda prefer something like that because it doesn't make me feel exhausted, but it's at a perfect point of having worked out and feeling great.
    Don't be embarrassed of taking care of yourself and doing good things about you. Let others think what they want, it doesn't matter at the end of the day.
