PISD Heat/Ozone Guidelines

During the hot days of summer, early fall, and late spring, there are frequently ozone alerts. There will be no outside activity if the temperature and/or the heat index is 95 degrees or greater, or when under a Red Ozone Alert, or Orange Ozone Alert.

Please provide the school with written notice if you would like your child to remain inside on days other than listed above. This applies only to temporary circumstances.  Longer term requirements for a student to remain indoors due to a medical condition require a note from the physician.

If your child has asthma or a respiratory problem, please remind your child to use caution when going outside for recess or PE. If your child uses an inhaler, please remind them of the importance of using it before exercise when indicated. The same is true for either hot or cold weather when those temperature conditions are known to trigger their asthma.

If permitted by your child's school, encourage him or her to bring a water bottle to take outside for recess and PE during the hottest days to stay well hydrated. A dehydrated child may complain of a headache or stomach cramping.

The following tips are offered for all students. Additional guidelines are provided in Plano ISD's Hot Weather Guidelines for Fine Arts Students.

Keeping it Cool

• Drink fluids before, during, and after outdoor activities. 
• If you feel thirsty, drink fluids! 
• If you bring lunch, pack a "Gatorade-type" drink. Sugars decrease the absorption of water by the body. Wear loose-fitting, lightweight, light-colored clothing.

Block the Sun

• Wear wide-brimmed hats while in the sun. 
• Use a sunscreen with an SPF 15 or greater. 
• Stay inside when possible. 
• If shortness of breath occurs during vigorous activity, stop the activity and rest in a cooler place. 
• Use a buddy system in high-heat activities
