The Truth About Sunscreen – Hidden Dangers and Natural Solutions

Summer is here and most of us can’t wait to enjoy the beautiful outdoors. Sunbathing, swimming, camping, playing on the beach… All of these activities are fun until you get that painful sunburn. 
So what do you do? You turn to sunscreen, and the higher SPF, the more protection you think you are getting. But is that really true?  
Turns out there are quite a few misconceptions when it comes to sunscreens. So we want you to not make potentially dangerous mistakes ever again, so from this summer onwards, we must ensure that we select our sunscreen carefully. Why? According to the experts, conventional sunscreens may cause more harm than good, and it is best that we stay away from them.
Shocking as it may be, there is substantial data that suggests the experts are right.
Far from protecting the skin, sunscreens are proving to be potential health hazards, causing skin cancer, because of their toxic ingredients that permeate the skin. 

Understanding the Health Effects of UV Rays

Wearing sunscreen and avoiding sunburns does not mean your skin is adequately protected.
UVA and UVB rays have very distinct properties when interacting with the skin. UVA rays damage skin cells called keratinocytes in the basal layer of the epidermis, where most skin cancers occur. They penetrate deeper into skin tissue where they release free radicals, damaging DNA and skin cells, promoting skin aging and causing skin cancer.
UVB rays stimulate the production of new melanin and a thicker epidermis, which are your body’s natural defense against UVA damage. They also cause sunburns, which are the body’s natural warning and protection system against UVA damage.
UVB rays are necessary to build the precursors to vitamin D in the skin. Vitamin D is a hormone essential to calcium absorption, promoting bone health. It is also essential to a strong immune system and helps protect against breast, colon, kidney and ovarian cancer. About one-fourth of North-Americans have low levels of vitamin D, which has been associated with increased cardiovascular mortality, colon cancer mortality, breast cancer, skin cancer, metabolic disease, hypertension, obesity, diabetes, osteoporosis, upper respiratory tract infections and other microbe-caused infections. 
Basically, for a sun protection lotion to be effective, it should block cancer-causing UVAs while allowing healing UVBs to interact with the skin.
Ironically, sunscreens create the opposite effect of what they are designed for. They block UVBs and allow harmful UVAs to penetrate deeper into the skin.
