In winter, the humidity inside houses, offices and schools is low because of heating systems. Forced-air heating is probably the most drying (radiator heat is a little less so). When skin is dry and itchy, winter itch can occur – especially in the elderly because their skin produces less oil.

And it’s even worse for those of us who enjoy outdoor activities in snowy climates – there’s the problem of increased exposure to ultraviolet rays.

For every 1,000 feet of elevation, ultraviolet exposure increases by about 2 percent. And snow reflects about 80 per cent of the ultraviolet light, compounding the problem.

Those who are indoors often think that they don’t need sunscreen. In fact, it is important for people to wear sunscreen all year long. Even if you are indoors, ultraviolet exposure can occur through car windows and cause skin problems over the years. Many people have extra sun damage on the left side of the face because of sun exposure through the car window.

If you are outside, be sure to apply sunscreen at least 30 minutes before sun exposure to ensure that it absorbs into the skin. Reapply every two hours.

Keep a lip balm or protector of SPF 15 or higher, and re-use it every half hour.
