As much as we all love the sun, we know that we must protect our skin from its harmful rays. Not only is sunburnt skin painful and unsightly, it prematurely ages the skin and is well known to cause skin cancer. Experts recommend no lower than SPF 15 is used with a high star UVA rating.
That said, Vitamin D, which is naturally produced by the body upon exposure to sunlight, is essential for bone health and to prevent diseases such as rickets. So a little sun is good for us.
