Summertime SafetyKeeping Kids Safe From Sun and SmogIf you spend time with kids in the summer, you want to keep them safe while providing fun outdoor experiences. Did you know that overexposure to the sun and air pollution can pose serious health effects, especially to children? You can take several simple actions to protect kids—and yourself. What's the Problem?Ozone can be protective or harmful, depending on where it is found in the atmosphere. Ozone is a naturally occurring gas in the upper atmosphere (the stratosphere) that protects us from the sun's ultraviolet (UV) radiation. Several chemicals released over time, however, have reduced the amount of stratospheric ozone left to protect us. Paying attention to the summer sun is more important than ever. Ozone at ground-level (the troposphere) is formed from pollutants emitted by cars, power plants, refineries, and other sources. Ground-level ozone is a primary component of a chemical soup known as "smog." Smog can be particularly high in the summer. Your chances of being affected by ground-level ozone increase the longer you are active outdoors or the more strenuous the activity. Health EffectsOverexposure to UV radiation can cause sunburns now, but can also lead to skin cancer, cataracts, and premature aging of the skin. Because kids spend so much time in the sun, and because even one or two blistering sunburns can double the risk of some skin cancers, protecting kids from the sun is especially important. Kids and teenagers who are active outdoors—especially those with asthma or other respiratory problems—are particularly sensitive to ground-level ozone. Ozone can cause coughing, throat irritation, and pain when taking a deep breath. It can also reduce lung function, inflame the linings of the lungs, and even trigger asthma attacks the day after ozone levels are high. Repeated inflammation over time may permanently scar lung tissue. The UV IndexDeveloped in partnership with the National Weather Service, the UV Index provides a daily forecast of the expected risk of overexposure to the sun. The Index predicts UV intensity levels on a scale of 0 to 10+, where 0 indicates a minimal risk of overexposure, and 10+ means a very high risk.
Actions You Can Take

-- The Air Quality IndexThe Air Quality Index (AQI) is a scale used by state and local air agencies to report how clean or polluted the air is. Ground-level ozone is one pollutant reported. An AQI of 100 or less (green or yellow) is considered satisfactory for most people. Air quality values above 100 (orange, red, and purple) are considered unhealthy, first for sensitive groups, but then for everyone as the AQI gets higher.
Although ozone reports are primarily made for metropolitan areas, ozone can be carried by the wind to rural areas, where it can cause health problems. Actions You Can Take
