Who actually thought that getting sunlight was bad ?

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 you…

What I've heard is people who don't get sun frequently, are at higher risk of melanoma. Like no sun then sunburn = bad bad

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.

Recently I've received an email from my eye specialist addressed to all her patients urging people not to look at the sun. At the same time I've also seen a similar public warning published in local media. Apparently there has been an sharp rise in people coming in with retinal damage from staring at the sun. They didn't go into details why someone would do that, but reading this on HN I can start to guess.

Until I see some definite proof, I'm going to put this in the FUD box.

There's seems to be a concerted effort at making people afraid of the sun. My guess is because the sun fixes a lot of problems, and problems mean profit.

Seriously, take a step back. If spending time in / looking at the sun was dangerous we wouldn't be here.

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…

So suddenly during an eclipse, your eyes have no idea what's painful/harmful anymore? Trust your experience, it's the closest you're ever going to get to truth.

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…

Cancer is a parasite, the sun kills parasites.

I've found the same with direct sunlight exposure. My distance vision is much sharper if I've been outside a lot recently. It seems similar to how exercise works elsewhere in the body. You can definitely get a neuromuscular reaction if the incident angle of the sunlight is direct enough. The trick (as with all forms of exercise) is moderation.

Might it be that when outside you tend to look farther than when inside? So distance vision gets used more and body adapts. Similar to how kids that spend time outside are less shortsighted.

Soap also kills parasites. And antibiotics!

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).

Is this some kind of weird meta joke or are people actually arguing about staring into the sun in 2025?
