Some sun exposure is good, and it's needed to synthesize Vitamin D, but you don't need a tanning bed for this. Vitamin D supplements are also readily available. There's plenty of medical evidence linking tanning and skin cancers. It's not the exclusive cause-- no one has said so-- but it's a contributor. So, use your brain indeed, and do as you think best for yourself in this matter. Maybe I'll see you (or the part(s) of you they excise-- I don't do autopsies anymore) soon or years from now to diagnose your basal cell carcinoma, squamous cell carcinoma, melanoma, Merkel cell carcinoma etc and contribute to my income. Or, you can save yourself a lot of trouble and stay out of my office or away from the surgeon's knife by taking care of yourself.

people claiming that tanning is safe in moderation...the Center for Disease Control and Prevention (CDC)[1] and the American Academy of Dermatology[2] begs to differ. (by tanning of course, i meant using the tanning beds)

there was also a mention of people needing to be properly hydrated. while true, there's also a myth associated about needing to drink so many cups of water a day, which is simply not true [3] (the myth will never die for some reason)



Indoor tanning is designed to give you high levels of UV radiation in a short time. You can get a burn from tanning indoors, and even a tan indicates damage to your skin.
...
people who indoor tan are more likely to report getting sunburned.

source: Center for Disease Control and Prevention



Even one indoor tanning session can increase users’ risk of developing squamous cell carcinoma by 67 percent and basal cell carcinoma by 29 percent.
Researchers estimate that indoor tanning may cause upwards of 400,000 cases of skin cancer in the U.S. each year.

source: American Academy of Dermatology

there's a reason tanning beds were outright banned in Australia and Brazil, and several countries in Europe banned for people under 18.
guess why.

Meh, I've never gone to a tanning salon and I've never intentionally lay out into the sun to tan (though there are times where I unintentionally got burned because I didn't use enough sunscreen/didn't use it often enough). This is because in addition to the fact tanning salons & tanning naturally can cause skin cancer, I can't get tan. Instead, I just turn red (and then have the burnt skin flake off a few days later).

also, someone claimed that Coffe caused dehydration, which is not true according to studies.
http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0084154
http://www.ncbi.nlm.nih.gov/pubmed/?term=maughan+2003+caffeine+ingestion+and+fluid+balance

i'm at a loss that someone would go and defend the tanning salons, while spreading myths. the fact that they ask people to "think" is ironic indeed. i strongly suspect that the claim that sunscreen causes cancer is also a myth spread by the media (just like how the media claimed that drinking less than 8 glasses made you dehydrated)
edit: and indeed, from what i found, it's not that sunscreen has some toxic effect on the body. rather, people will spend more time in the sun than they should. sunscreen can only provide so much protection.

according to a bias report


According to the report, it seems that one of three things are the culprit. Either we’re not wearing the right kind of sunscreen, we are not reapplying sunscreen often enough, or we’re getting a false sense of security from our sunscreen.

notice how the report then throws this info out the window and squarely blames the sunscreen (even though the last two are really the culprits)
the blame shifting is probably to make the news more "shocking" and trending.

the researchers only claimed that


People tend to think they’re invincible once they’ve put it on and end up spending longer out in the sun, increasing their overall exposure to UV rays.

in other words, sunscreen helps, but you need to be careful not to be under the sun for too long, which at this point is common sense.

(it should be noted that the same British Association of Dermatologists make no claim that sunscreen can be a risk factor. much to the contrary, they recommend appying it regularly as needed http://www.bad.org.uk/for-the-public/skin-cancer/sunscreen-fact-sheet )

I don't use sunblock. I'm allergic to it. I have dark skin but I grew up knowing that there are limits to being in the sun due to living in the tropics. I also do end up with a tan in the summer. Dark skin just gets darker then. Since its spring I'm getting my vitamin D time.

you can always get vitamin D from your diet (example: salmon, eggs) as well as vitamin supplements.

Diet isn't the best source of vitamin D. I'll only rely entirely on diet in winter.

I love how you come with clearly american sources as if they're accepted by the ouside world...

Personally i wouldn't give two shits what the CDC that's currently allowing Monsanto to do whatever the hell they want is saying is "good for you". Americans are the most unhealthy in the world.
Also, having traveled to Australia, they're probably banned because you get an excess of sun simply by standing outside at a summer midday in Australia. Brazil i'd assume has similar climate.

More to the point, there's a reason the sun was/is worshipped. It is life.

I will make a case for the benifits of natural sunlight cause I would say the complete avoidance of sunlight is stupid and steeped in a myth that the sun is somehow bad despite the evidence ... -_- Way to go broken/outdated sects of scientific researchers!

I mean just like anything it's quite nuanced take for example people who are lighter skinned obviously can't be in the sun as long as say a person with darker skin, unless they want to get sun burned and that is unhealthy just like getting no sun.

Tanning beds are okay for vitamin D production but staying in for 30-60 is pointless and kinda harmful. Shorter times are okay if your going for vitamin D production since we make quite a bit in a short amount of time.

As for the benifits of the sun would be the serotonin and dopamine (possibly connected with a gene that regulates Seasonal affective disorder, when I find the link I'll post it.) vitamin D ( While you can get it from food and supplements some of the times it just doesn't raise blood levels of vitamin D the same(as for supplementation I can say it's actually way better than sun exposure tbh it's just an assumption but in the future I think we might see research that suggests this since we usually didn't get 10,000IU's through diet/orally nor could we ever really till recently) , nitric oxide, and melatonin suppression and then melatonin secretion during the night. Sunlight entrains a persons circadian rhythm which is highly ignored and imo super important in regards to hormones like leptin, insulinand ghrelin and probably a whole fuck load of others we don't know about since their tied into circadian biology. And probably a bunch of other benifits we don't know about yet.

Here's some reading material

This ones pretty lenghty( and I haven't actually read it but it comes from someone I trust so fuck it ) and goes into the hormonal aspect of circadian rhythms.
http://onlinelibrary.wiley.com/enhanced/doi/10.1111/dom.12516

Here's one that goes into vitamin D and why sunlight is superior to supplemntation
http://caloriesproper.com/vitamin-d-fiat-lux-and-circadian-rhythms/

Here's an interesting article that goes into AM light exposure and weight

http://m.medicalxpress.com/news/2014-04-people-exposed-earlier-sunlight-leaner.html

Heres a study done on light exposure during the day and how it effects light suppression of melatonin at night.
http://www.ncbi.nlm.nih.gov/pubmed/26141542

And another link on melatonin

Skin cancer and light exposure
http://caloriesproper.com/sunlight-and-the-circadian-rhythms-in-your-skin/

I think sunlight or even light in general is very nuanced just like a bunch of other things and if your adapted and have a bulid up of endogenous sunscreen ie. Polyphenols and carotenoids etc, and things like that then sun exposure is cool but everyone is different and each person has their own threshold and we all live in different environments so yea....

TL;DR:Sun isn't bad it just depends on your context , go out in the sun just don't be an idiot about it. Also light is kinda like a drug a very powerful drug.

All good comments with a few i disagree on I have seen what tanning beds have done yes
no shits about it I have seen cancer on moles of skin i have seen leather skin so do as you want.. I created this thread to make others
aware. I never said not to go into sun but nothing wrong with sunscreen! make the choice yourself but> don't tell me what I have seen first hand as people walking into my clinics and me telling them they need to go get cancer treatment. Thank God, I no longer have to deal with
it i have moved into another career.

there's a difference between exposure to UVs through sunlight and through tanning beds.
as explained in the article posted prior, tanning beds give a much higher dose of UV over a very short time.

British Association of Dermatologists:


The recent sunbeds Bills in England and Scotland, in which under 18’s were banned from using tanning machines, are certainly a step in the right direction in the fight against skin cancer.
...
a review by the International Agency for Research on Cancer (IARC) found that first exposure to sunbeds before the age of 35 years increases the risk of melanoma by 75 per cent.
...
Recommendations:
The use of UV equipment for cosmetic tanning should be strongly discouraged.

http://www.bad.org.uk/for-the-public/skin-cancer/sunbeds

unless you somehow think that other countries also got it "wrong" when it comes to tanning beds.

edit:
The European Academy of Dermatology and Venereology also discourages the use of tanning beds (also known as "sunbeds")


Avoid artificial ultraviolet light (sun beds or tanning lamps) and protect yourself from excessive sunlight.
