Prevailing common sense says to be very wary of the sun and its harmful effects, so many of us load on the sun screen before going outside. Who wants melanoma? No one. But wait. Several studies imply that many commercially available sunscreens don’t block damaging rays form the sun, don’t remain effective as long as advertised, and/or contain toxic and carcinogenic ingredients that are worse than the sun itself. Plus sunscreens can block Vitamin D which is vital for good health.
We all want what’s best for us (and our kids). Some sun exposure is good for us, but we also know that sunburns are not. Take precautions to prevent overexposure, but do your own research and use your own good judgement over wisdom of the masses in mitigating the harmful effects of the sun. Here are some articles to help you get started:
FDA Sheds Light on Sunscreens
(note that as of May 2012, the FDA was investigating whether spray on sunscreens presented a health hazard if unintentionally inhaled).
