When to Wear Sunscreen
Sunburn happens when you're exposed to a lot of UVB rays from the sun. It only occurs in the middle part of the day in the summer.
When the sun's angle is below 35 degrees, you don't have to worry about sunburn because the amount of UVB is insufficient.
A good sunscreen will also protect your skin from UVA rays, responsible for thickening and aging of the skin.
Who Needs Sunscreen
The darker your skin the less likely you are to get sunburn or skin cancer. However, dermatologists recommend using sunscreen anyway.
Safety of sunscreen
Science has not found any serious threats to your health from using sunscreen.
The chemicals in sunscreen, oxybenzone and octinoxate, are dangerous to coral reefs, which is why Hawaii has banned them.
There aren't any effective alternatives to sunscreen besides avoiding the sun.

Results On Multivitamins
- In studies testing the four common supplements of multivitamins, vitamin D, calcium and vitamin C, there was no reduction in the incidence of heart disease, stroke or premature death.
- Folic acid supplements showed a reduction in heart disease and stroke. But high levels of folic acid in the blood may increase the risk of prostate cancer.
- Among those taking statin medication to lower blood cholesterol, slow or extended release vitamin B3 (niacin) increased the risk of early death by 10%.
- Antioxidant supplements also had a marginally significant increase of early that risk.
Multivitamins Research Review
- There’s some evidence for taking folic acid for the prevention of heart disease and stroke, and also for taking B-complex vitamins that include folic acid for stroke.
- As there was no reduction in early death from taking supplements, it does not work against poor dietary habits.
- Taking supplements is very different from eating whole foods. The latter rarely causes complications and the former may lead to the consumer missing out on healthy phytonutrients found in the former.
