Sun Safety Tips

I care about the sun because:

UV rays: the good, the bad, and the ugly

The good: the “sunshine vitamin”, vitamin D

UV rays from the sun help our bodies to produce vitamin D, an important vitamin for bone health. The exact same UV rays that cause sunburn are what our bodies need in order to synthesize vitamin D.

Sunscreen can help prevent the negative consequences of sun exposure, but it also hinders our ability to synthesize this essential vitamin. Without the proper tools, it’s hard to know how much sun exposure is enough to prevent sunburn, while maintaining a healthy vitamin D status. This is where Sun Index comes in.


The Vitamin That May Saves Your Brain!

The bad: sunburn and premature aging

The sun emits both UVA and UVB rays. UVB rays cause sunburn while UVA rays are responsible for premature aging. Not only is a sunburn painful and uncomfortable, it indicates that your skin cell DNA has been damaged by the sun. Enough damage can cause premature aging, also known as photoaging. As you get older, you may notice your skin becomes rough or discoloured, or you may start to notice “spider veins” forming in regions that are exposed to the sun. These are the visible signs of photoaging.

The ugly: skin cancer

Skin cancer can result from overexposure to UV rays. Melanoma is the most serious type of skin cancer, and it can be lethal. Individuals with skin type 1 (pale skin, light hair and eyes, burn easily in the sun and never tan) are at the highest risk of developing skin cancer. Catching suspicious spots early can mean the difference between life and death. Melanoma spots are usually asymmetrical with an irregular border, and take on a colour unlike other moles on your body. Monitor your moles for these signs, especially any new moles that develop after you turn 30.
