Ultraviolet (UV) radiation is the invisible killer that you can’t see or feel. UV radiation can be high even on cool and overcast days. This means you can’t rely on clear skies or high temperatures to determine when you need to protect yourself from the sun.
It is a common misconception that heat and UV rays are directly related, but they are actually two different types of energy:
- Infrared radiation is felt as heat.
- Ultraviolet (UV) radiation is invisible and cannot be felt, but it damages skin
Sun Safety Checklist for Cooler Weather
- Check the UV Index: If the UV level is 3 or above, you need to protect your skin, regardless of the temperature.
- Use Sunscreen: Apply broad-spectrum SPF 30 or higher, particularly for outdoor activities.
- Cover Up: Wear clothing that covers as much skin as possible.
- Protect Your Eyes: Wear sunglasses that offer 100% UV protection, as the sun is lower in the sky during autumn and winter.
