Exposure to UV radiation from the sun damages your skin, and increases your risk of developing skin cancer, wrinkles and age spots. Children are especially vulnerable because they tend to spend more time outdoors and can burn easily. Here are four ways you can protect yourself and your family from UV radiation damage:
- Avoid sun exposure in the middle of the day — between [latex]10[/latex]AM and [latex]4[/latex]PM — when the UV rays are strongest.
- Use a broad-spectrum sunscreen with a sun protection factor, or SPF, of at least [latex]30[/latex], even on cloudy days.
- Wear sunglasses that block both types of UV radiation — UVA and UVB rays.
- Sunscreens don’t provide complete protection from UV rays. You also should protect your skin with dark, tightly woven clothing that covers your arms and legs, and a broad-brimmed hat that provides more protection than a baseball cap or visor. [1]
