Are we suckers of the sunscreen industry?

As someone who rarely uses sun block anyway, I am all in favor of this guy's thesis.

Did anyone actually realise that the sunscreen usage information is sponsored by the makers of sunscreen? Are we just the suckers of another advertising gambit?

Are we just pasty patsies?

The Sun IS good for you, it DOES have benefits, for UV, for mood improvement, etc.

... Quote:
'I was treated almost as a villain, as if I had said something really outrageous.'
Michael Holick, professor of medicine and physiology at Boston University School of Medicine, is still sore about being asked to resign his professorship of dermatology in May 2004.

His crime? He wrote a book called The UV Advantage, which suggests that exposing yourself to sunlight without sunblock for five or 10 minutes a day can be a good thing, providing us with Vitamin D and helping to strengthen our bones and protect against illnesses like type II diabetes and multiple sclerosis.
... Quote:
'It was the "without sunblock" bit that they didn't like, apparently it's forbidden to tell people to go out without sunblock.'
he said.

All Holick says is that, while we should avoid tanning and staying in the sun for too long, we should recognise that sunlight 'can maintain bone health and prevent rickets in children'. Hardly Copernican, convention-shattering stuff.

But Holick offended against a contemporary religion, one which says that sunlight causes skin cancer, that tanning is the irresponsible act of reckless individuals.

On both sides of the Atlantic, government health campaigns warn of the apparent dangers of staying out in the sun. The UK Department of Health advises Brits to 'stay in the shade or indoors' on hot, sunny days - or 'if you can't avoid being out in the sun, apply sunscreen (factor 15+) and wear a t-shirt, hat and sunglasses'.

Yet like the flat-Earthers who challenged Copernicus, the claims of the 'sun awareness raisers' often overlook the facts - which suggest that the link between sunlight and skin cancer is more complex than they allow.
... Quote:
'The message that was initiated 20 or 30 years ago, with the advent of sunscreen, was a reasonable one. Namely that you should not bake outside. But now it's been taken to an extreme and people aren't thinking straight anymore. We have become scared of the sun,
reckons Holick.

It is clear from Holick's book that he is no sun-worshipping tan god. It begins: 'I do not advocate tanning.' There are tables at the back of the book where Holick spells out exactly how long you may spend in the sun, depending on where you are on the planet and what time of year it is. The book's main message is that humans get 90 to 95 per cent of their Vitamin D from the sun, and that therefore some unblocked exposure to the sun is necessary for Vitamin D upkeep.

Holick never imagined that saying this would have such 'terribly serious consequences'. He says the sunscreen industry took out a paid advertisement in US newspapers the month before his book came out, personally attacking his reputation.

He was called in by Barbara Gilchrist, chair of the Department of Dermatology at Boston University School of Medicine, and told that 'your thinking is not in line with ours'. Holick groans that the sunscreen industry is 'a major funder of the dermatology community in the US, especially the American Academy of Dermatology….' 'So I was asked to resign from the department', he says, though he remains at Boston as a professor of medicine and physiology.

For Holick, one of the most grating things about being accused of behaving irresponsibly is that the much-talked-about link between sunlight and skin cancer is actually quite complex.

Sun awareness campaigns focus on malignant melanoma, moles which turn cancerous. Yet these are a relatively rare form of skin cancer and the one least related to sunlight.

The majority of skin cancers in America and in Britain are basal-cell or squamous-cell carcinomas, both of which are highly correlated with sun exposure and which commonly appear on the head, neck and arms - those parts of the body where skin is most likely to burn. These two cancers are more common in middle-aged or elderly men than in the young; they tend to grow slowly and are quite easily treated with surgery or radiotherapy.

'There may be a million squamous or basal-cell cancers in the US a year', says Holick, 'but that's like the bread and butter of a dermatologist's work. They can be treated. Of the more dangerous melanoma, there are around 50,000 cases in the US each year, and around 8,000 die.

It is still quite rare that a young woman will wind up with melanoma and die. If she does, often the melanoma has developed on a part of the body not exposed to sunlight.'

Melanomas commonly appear on these 'non-sun exposed' parts of the body, like the back of the legs, the soles of the feet and the buttocks. Indeed, there is a similar incidence of malignant melanoma in Japan as there is in America and Britain, and the Japanese are not known for spending long hours sunbathing.

In Britain, as in America, melanomas account for less than 10 per cent of skin cancers; there are around 4,000 cases a year in Britain, causing around 1,500 deaths.

Holick points out that when melanoma is sun-related, it is more common among certain types of people. 'It's associated with those who have a markedly high number of moles', he says. 'We also suspect there is a genetic contribution, from a family history of the disease. It is common in people who have red hair and in those who sunburn. The number of sunburning experiences increases your risk of melanoma. So some susceptible people who don't get moderate sun exposure, and then rush out on the weekend to burn and bake for several hours, are putting themselves at high risk.'

Holick says there is a powerful conformism on the issue of sunlight and skin cancer, 'and if you question it….well, look at what happened to me'.

He pins much of the blame on the 'sunscreen industry', which makes financial gain from panics about skin cancer. No doubt there is some opportunism among sunscreen manufacturers and dermatologists; indeed, in the 1990s Professors Sam Shuster and Jonathan Rees of Newcastle University accused some of their academic colleagues of 'making a living out of perpetuating the skin cancer scare'.

Where the anti-sun brigade tells us that going out in the sun in anything less than Victorian garb will put us at risk of cancer, Holick says that staying indoors will also put us at risk of cancer in the longer term. It is an indictment of our fearful, irrational times that one of the few ways you can challenge a panic is by launching a counter-panic; so those who question the obesity obsession claim there is a growth in eating disorders instead, while those who challenge the scare over the MMR vaccine raise the spectre of a measles epidemic if the MMR take-up rate continues to fall.

I don't often use sunblock, mostly only when I'm going to be out for long hours in the sun and would rather not come in with a raging sunburn that'll ache for days. it does help, imo, but I don't think it's necessary in the quantities that are suggested by 'medical experts'.

I used to use sun-block alot on my son when he was very young and we went out on long walks in the summer, havent used any in yrs now, some can do more damage than protection !

Personally I just hate the sun paranoia, where we all run and hide to get away from it. I love the sun, and am out in it as often as I can be. Sure there may be a risk of developing skin cancers from sunburn, but thats just one of a zillion fears you have in life anyway.
