Im just curious to know how many times a year schools cancel practice because of heat?
When i was in school, a little over 10 years ago, we hardly got water breaks, much less days off because it was hot. It reached a 100 degrees multiple times in the summer of 98 and 00, and we practiced as usual and everybody was okay, with a water break about every 45 minutes to an hour.
Since this rule was put into to place, how many ties have schools cancelled practice?

I know some schools 'move inside' instead of cancelling. So players are to bring gym shoes to practice on days where the heat may be too high.

I believe a major change is the use of artificial turf fields. These fields are great for much greater use but they do have a downside - heat.

Being artificial and most (if not all) have black colored ground rubber base that heats up faster and holds the day time heat - even into the early evening. The heat index on turf field may be 10-20 degrees higher than an adjacent natural field. So when schools practice on turf they need to be measuring heat indexes more often and sooner than natural fields.
