First responders were called to John Marshall High School’s football field on Thursday afternoon after 37 band members became overwhelmed by heat.

There were no serious injuries but a good number of students did have to go to the hospital.

Band members from the middle schools and high school were practicing for Youth Night at halftime Monarch Stadium, when a mix of the heat and all the exertion took a bit of a toll.

Several students started complaining of dizziness of nausea with a few even throwing up. That’s when the school district decided to take some precautionary measures to make sure no one got too sick.

In all, 37 students were treated at three different area hospitals.

Students who were not transported were checked out by a school nurse and other EMTs.

All parents at each school were informed of what was happening.

The major issue was a mixture of the heat and the brand-new field turf, which gets much hotter than the grass on which the bands usually practice.

This practice has been happening for more than 30 years but always on a grass field, according to school officials.

After Thursday’s incident, they’ll be looking at some other options that will be safer for students.
