Who actually thought that getting sunlight was bad ?

There is a lot of weird discussion on English-speaking forums that you should always always wear sunscreen, even if the day is grey, because skin cancer is a constant risk.

I do not get if it’s a massive and long-running marketing campaign that has brainwashed the entire population, if it’s because many living in US and UK have a very white skin tone thus burn easily, or what else. Skin cancer is a fact of life, but for a species that evolved in the sun, I do not believe one bit that sun exposure, which incidentally is linked to many benefits because it’s so bloody normal, is something that can only be dealt with modern technology and we should be deathly afraid of it. Sure, UV radiation can cause mutations, but our immune system has evolved over billions of years to deal with this exact problem.

By all means use sunscreen if you have to spend a lot of time in the sun and risk a very unpleasant sunburn, but I wish someone would explain the Anglo obsession with daily sunscreen routine.

Yeah, most of the time our immune system deals with it, but sometimes it misses one roge cell and you've got cancer. That's why you want to limit your exposure to mutations even if you're somewhat adapted to deal with them.

Then it's a matter of looking at studies and statistics (I know, not very popular these days) and decide for yourself. Personally, I'll keep putting on sunscreen, as I sunburn easily ;)

I've had a malignant melanoma, my mother and extended relatives had it as well (including a great uncle I never met who died from it), 4 (of my 9) siblings have had multiple, mostly those of use who have red hair/fair skin. I don't think I've ever heard of a greater risk of skin cancer due to genetics/familial occurrence than I have.

After my mother got it and had a huge chunk taken out of her leg when I was very young, we have had it drilled into our heads that the sun was going to kill us and we needed to cover up and lather in sun screen for even the slightest possibility of sun exposure.

Obviously that didn't help much as many of us still got it anyway, hah!

But yea there are some folks who are terrified of the sun. I personally think 15-20 minutes unfiltered sunlight is good for me, but beyond that I'm looking for the nearest shade or trying to cover up.

I am very white, but getting sun feels very healthy for my skin. Obviously I don't want to get burned bad, but good sun exposure helps my skin feel softer and less inflamed. My grandfather also spent most of his days out in the sun gardening, and my mom was just commenting a few months ago about how surprisingly smooth his skin is (and he's 92).

On a related note: I also think looking at the sun is healthy for our eyes. I've been getting more sun-in-my-eyes exposure, and at the last optometrist I had, he was surprised to find that my vision improved since my last checkup.

Anyone thinking of doing this, don't. There's a reason we don't directly look at solar eclipse. Here's a excerpt from [1]

> Usually we close our eyes in reflex due to intense light from the Sun, but on day of an eclipse, the intensity of sunlight is decreased and we can view the Sun through naked eyes. While we watch a solar eclipse without any protection to our eyes, the ultraviolet rays penetrate our eyes and cause retinal burn, leading to loss of central vision.
