This is an H3
The sun’s rays are strongest between the hours of 10 a.m. and 4 p.m. These also happen to be during school hours for much of the year. UV radiation is, on average, 3 or higher during the months of March through October in Colorado, and experts recommend sun protection be required when the Index is 3 (moderate) or higher 1.
Children’s exposure to UV rays could be reduced up to 60% if they avoided the sun during peak sun intensity hours 2. Whenever possible, try to reschedule outdoor events for early morning or late afternoon.
To minimize UV exposure during peak UV times:
- Advise schools to keep students inside when the UV Index is 6 or above
- Make indoor areas available to students. Allow students to choose visiting the library, study hall, gym, or computer lab as alternatives to going outdoors during peak sun intensity hours on high sun intensity days
- Offer indoor physical activities, such as aerobics, jump rope, basketball, volleyball, gymnastics or dance on days of high sun intensity or schedule outdoor physical activities early in the day
- Plan field trips to interesting indoor locations (e.g. museums, science centers, theaters) or where adequate shade is available
- Schedule outdoor activities and field trips before or after peak hours whenever possible
- Encourage all field trip and athletic event participants to wear sun safe clothing, hats, and sunscreen
- Include requests for sun protection (clothes, hats, sunglasses, and sunscreen) on all permission slips for field trips and other outdoor events
- Create rotating schedules for physical education classes in elementary schools so the same students are not exposed to high UV times of the day consistently
- Schedule school practices before or after peak sun intensity hours
- Disseminate tips for scheduling time outside in a sun safe way
- Adopt a district policy to encourage indoor physical education during high UV times

An easy way to know the UV intensity you face daily is to check the UV Index. The UV Index is a joint effort between the National Weather Service and the Environmental Protection Agency. It provides a daily forecast of the expected intensity of the sun for numerous U.S. cities. The Index predicts UV intensity on a scale of 0 to 11+, where 0 means minimal risk and 11+ means an extreme risk of overexposure. The UV Index is published online and on the weather page of many daily newspapers.
