You already know that a trip to the beach can give you a nasty sunburn, but the nitty gritty of sun safety is actually much more complex. Wrinkle-causing UVA rays and burn-inducing UVB’s can pose a serious risk to your health (and good looks). So what can you do? Kevin P. Boyd makes the case to slap on some physical or chemical SPF daily.

    Please do your own research. Do not use sunscreen. Sunscreen causes cancer not the sun. If you wish to use a sunscreen, use coconut oil. Coconut oil has natural sun blocking abilities and other benefits. Sunscreen is terrible for your body. Just do a few minutes of research, you will find out how terrible it it for you. Don't support these corporations that are killing you.

    Through living in tropical region, I always struggle with this doubt whether I should use sunscreen for protecting from strong sunburn or should refrain from using it that contains lots of chemical substances that cause our skin really dry situation.hah

    In recent decades, the mainstream media has spread such fear about skin cancer that most of us religiously lather ourselves in sunblock as soon as we hit the outdoors. While it is certainly true that it is important to take precautions to prevent the skin damage that can result in melanoma, it is equally important to ensure that we get sufficient exposure to the sun to ensure our bodies can produce the hormone vitamin D3.

    This hormone is absolutely essential for the maintenance of healthy bones and teeth, insulin regulation, good cardiovascular health and a strong immune system, among other things. Low levels of vitamin D have been associated with an increased risk of cancer, Alzheimer’s disease, depression and other serious illnesses.

    The results of a recent study by the American Osteopathic Association, which found that close to 1 billion of our planet’s inhabitants are deficient in vitamin D, are therefore truly alarming. The researchers found that this deficiency can be attributed to a lack of sun exposure, chronic disease and the use of sunblocks, which decrease vitamin D production by a staggering 99 percent.

    The human body only produces vitamin D when skin is exposed to direct sunlight.

    I mean how did the human race even survive on this planet if some sun exposure can do so much damage to us?
    I'm also pretty sure our ancestors didn't have any sunscreens back then

    People who have dark skin tones often believe they’re not at risk for skin cancer, but that is a dangerous misconception, says dermatologist Maritza I. Perez, MD, a senior vice president of The Skin Cancer Foundation. “Anyone can get skin cancer, regardless of race,” she says. While incidence of melanoma is higher in the Caucasian population, a July 2016 study in the Journal of the American Academy of Dermatology showed it is more deadly in people of color. African American patients were most likely to be diagnosed with melanoma in its later stages than any other group in the study, and they also had the worst prognosis and the lowest overall survival rate.
