New heat safety rules are set to take effect for Texas high schools. These rules will apply to outdoor activities, including athletics and marching bands. The changes are mandatory and will be implemented statewide.

The University Interscholastic League has made a formal rule change, which will come into effect on August 1. This means that all high schools in Texas, including those in the Houston area, will need to adhere to the new standards. Further details about the specific rules and how they will be implemented can be found through the University Interscholastic League or other sources, such as FOX 26 Houston.
