Sunburn is a fat going rancid inside you, and the compound it produces has a name. 4-hydroxynonenal. An aldehyde. Measurable, published, sitting in the literature for forty years. It does not come from nowhere. It is a breakdown product of omega-6. Specifically linoleic acid and the arachidonic acid your body makes from it. Linoleic acid has two double bonds. Every double bond is a weak point where oxygen gets in. Saturated fat has none. Monounsaturated has one and it is hard to reach. Your cell membranes are built from whatever fat you have been eating, on a turnover of roughly two years. Ultraviolet light hits the skin and strips a hydrogen off one of those weak points. That starts a chain reaction called lipid peroxidation, and a chain reaction does not need more light to continue. It propagates on its own. The chain breaks the fatty acid apart. Out come 4-hydroxynonenal and malondialdehyde. Those aldehydes cross-link proteins, damage DNA and trigger the inflammatory cascade. The redness, the heat, the swelling, the peeling. That is the immune response to the wreckage, not the sunlight itself. More linoleic acid in the membrane means more fuel in the fire. Linoleic acid in American body fat ran at about 9 per cent in 1959 and reached 21 per cent by 2008. Your grandfather worked outdoors all day in a vest and came home brown, on membranes built from lard, butter and dripping. He was less flammable, and nobody had told him he was doing anything brave. Four grams of omega-3 a day let volunteers take 36 per cent more UV before burning. Fish oil cut the inflammatory signal in irradiated human skin by more than 60 per cent. Sunlight is not the accelerant. It is the ignition. Fifty years of advice about what to spread on your skin, and not one word about what you built it out of.

I’m a dermatologist. I’m supposed to say there is no amount of safe sun exposure. But I won’t, because that’s a lie. The attached shows how much sun is safe in different cities at different times of year. What do I mean by ‘safe’? I mean this: UV causes DNA damage and skin cancer. But, shockingly, your body repairs that damage. As long as the damage doesn’t outpace repair and start accumulating it shouldn't increase your risk of skin cancer. Data just came out that tells us how much UV you can get without damage accumulating. They took the people most susceptible to DNA damage from UV and exposed them to UV, then did skin biopsies to measure the damage, then more skin biopsies to measure the repair, and repeated it daily for 4 days. At 1.6 ‘Standard Erythemal Dose’ (SED) there was no accumulation of damage. So, the attached charts show how much sun it takes to get 1 SED in different cities at different times of the year at different times of day. And there are extra safety margins built in. It assumes a perfectly clear day with zero air pollution and that the sun is hitting your skin perpendicularly. Unless you’re laying flat, most sun is hitting you at an angle, which isn’t nearly as intense. But a bigger question you might be asking is ‘Why would a dermatologist be telling you to get sun in the first place?’ Because getting sun reduces your risk of death. Mostly by reducing your risk of heart attacks and strokes. That is very well proven. But it’s also very likely that sun exposure reduces your risk of autoimmune disease, dementia, cancer and depression. It’s just not as well proven as the protection against heart attacks and strokes. And before you reply and say ‘just take vitamin D!’, know that it has been ROBUSTLY proven that vitamin D has little (if any) benefit for preventing any of the above. Vitamin D is mostly useful as a marker of if you’re getting enough sun. What do I do myself and what do I tell my patients? Get as much unprotected sun exposure as you can without getting a burn. That’s my GUESS as to what has the best risk/benefit ratio. Dying of skin cancer is actually really rare, especially when compared to the risk of heart attacks, strokes, autoimmune disease, dementia and other cancers. But I’ll admit it’s not for sure best to get as much sun as possible, since sun does increase the risk of skin cancer and it might be the case the benefits plateau at a low level. So, if you’re really worried about skin cancer stick to the charts. The best science I can find says that amount won’t cause skin cancer. The takeaway? Sun is good for you, just don’t get a burn.

Dermatology is wrong about the sun. And it's killing people. I'm a dermatologist. 226 publications. I should know. Avoiding the sun increases the risk of dying as much as being a smoker. We can fix it. For decades, dermatology's message has been simple: avoid the sun. Wear
