New heat safety rules are set to impact football and marching band practices in Texas schools. As of August 1, schools will be required to follow these rules, which could result in shortened, delayed, or canceled outdoor practices during extreme heat. The University Interscholastic League is now mandating the use of the Wet Bulb Globe Temperature to determine safe practice conditions.

This measurement assesses the heat stress a person experiences outdoors, differing from the commonly known heat index. Further details on the new rules and their potential impact on local schools are available from Click2Houston KPRC2 Local.
