It’s three in the afternoon. The heat from the sun outside warms your skin. You sit there quietly in front of your windowsill. The book in your hand transports you to a magical world of wonder. But, did you know that the little warmth of light from the outside is exposing you to harmful UVA rays?

Your glass windows can only filter out one type of radiation — UVB rays. The UVA rays are what you should really look out for. UVA rays can penetrate deeper. At least 50 per cent can pass through the window glass you thought was protecting you.


Prevention is always the key. Apply sunscreen on any exposed areas. Yes, do this even when inside your home. You don’t have to apply sunscreen all the time, though, unless you’re always in front of the window.

The Skin Cancer Foundation recommends the use of sunscreen with at least SPF 15. It should include UVA-screening ingredients such as zinc oxide, avobenzone, titanium dioxide and oxybenzone.

For security, consider solar window films. It’s a window tint specially made to block out those UV rays.

Your skin’s constant exposure to the sun’s UV radiation can accelerate skin aging by several years. Based on an article entitled Clinical Interventions in Aging, there are eight women and two men who got considerable amounts of sagging and wrinkles on one side of the face. They all worked indoors.

The side of the subjects’ faces that was closer to a window showed more signs of sun damage. The wrinkles on the cheeks and around the eyes were worse on the exposed side. They had rougher skin texture. Their faces were also drier and duller; the crow’s feet were deeper. If this gets worse, it increases the risk of skin cancer.

Who doesn’t want to look younger than their age and live longer? Better start on those precautions before it’s too late. Your wrinkle-free face will thank you in the long run.
