Out on the gridiron in August, it's hot. It's days like these coaches walk the line of having practice and keeping their athletes safe in the heat.
"You always worry about this because of the heat index and the stuff and what they are calling it now," said parent Bill Danenhauer.
To better know when to make the right call on the heat Millard Public Schools is switching to a new policy called the Wet Bulb Globe Temperature chart.
"The Wet Bulb takes into consideration the temperature, the wind, the humidity, direct sunlight and cloud cover, all those factors," said Craig Holz, Millard South High Athletic Trainer.
It's a chart format that breaks down what to do at each temperature level.
The WBGT doesn't just highlight duration of play, it also goes into what equipment should be worn and how often the kids need to take water breaks.
The system aims for a balance in sports play and safety.
"When they are involved in an activity or a drill they go hard, and when they are not they take their helmet off and get some water," said Coach Andy Means, Millard South High.
As the players sweat on the field, the chart clearly tells coaches and trainers what they can do during practice.
"Thank goodness for the wind that we have the wet bulb is in an area, just shoulder pads and helmets, and then we will just practice two hours maximum," said Holz.
Omaha Youth Football is also switching to this standard and that relieves these young athletes parents.
"Oh I think it's good it protects the kids, and that's the main thing we don't need anyone sick or injured or anything like that," said Danenhauer.
