Sun Safety

Is there anything better than a gorgeous sunny day? Nothing feels better than the warm sun on your skin, and when the sun is out, more people spend time doing outdoor activities with family and friends. It is important to be aware, however, that sun exposure has both positive and negative effects.

Positive effects of the sun include warmth (infrared radiation), light (visible light), and vitamin D3 synthesis in the body. Sunlight also enhances people's moods and kills pathogens. Despite these advantages, overexposure to UV radiation can also have adverse health effects, including sunburn, premature ageing, skin cancers, diseases of the eye, and immune suppression.

Before going out to enjoy the good weather, make sure you are aware of the risks associated with prolonged exposure to the sun and the measures you can take to protect yourself and your family.
