The 3 Worst Reasons Not to Wear Sunscreen

Everyone from Fortune Magazine to your 80-year old aunt is giving out sunscreen and skincare advice.  As you know, I'm a nut about studying this stuff, so I've pulled together the 3 worst sunscreen 'facts'  that I've seen lately:

1.  Fiction: "80% of a person's lifetime exposure is acquired before the age of 18".wearing sunscreen

Fact:  This is statistically impossible and only true if everyone spent the rest of their lives living in a cave. Actually, only 23% of lifetime exposure occurs by age 18. (skincancer.org)

2.  Fiction:  "I only need to use sunscreen in the summer when I'm outside"

Fact:  UVA rays (95% of rays) are present with relatively equal intensityduring all daylight hours throughout the year, and can penetrate glass.  UVA rays are known to play a major role in wrinkling and can initiate skin cancers.  (skincancer.org)

Fact:  UVB rays (5% of rays) are the ones that are most present between 10am and 4pm from April to October.  UVB rays are the ones that cause burns and plays a key role in the development of skin cancer.  (skincancer.org)

 3.  Fiction:  "I can't use sunscreen I am vitamin D deficient."

 Fact:  Vitamin D is only produced from UVB rays.  If you live north of Atlanta UVB rays are only effective in producing vitamin D in the summer time because that is when the rays can penetrate the atmosphere.

Fact:  Experts suggest 10 min a day in the sun for vitamin D.  That's it.

Fact:  Take a vitamin supplement, add foods like salmon, cheese, fortified cereals and egg yolk to your diet. Subjecting yourself to radiation so you can get vitamin D doesn't make sense.
