Raising Expectations for Managing Heat and Humidity

February 19, 2013

The MHSAA Representative Council is scheduled to vote on March 22, 2013, to approve a “Model Policy for Managing Heat and Humidity” that would appear in the 2013-14 MHSAA Handbook.

The policy, patterned after a mandatory policy of the Kentucky High School Athletic Association, requires that temperature and humidity readings be taken at the site of activities 30 minutes before the start of the practice or competition and again 60 minutes after the start of that activity.  The readings must be recorded in writing and kept in the files of school administration.  Inexpensive devices may be used that automatically calculate the “heat index.”

If the heat index is below 95 degrees, only normal precautions are required.  However, readings of 95 to 99 degrees and then 100 to 104 degrees require additional precautions; and all activity must be postponed or suspended if the heat index climbs above 104 degrees.

When the air temperature is below 80 degrees, there is no combination of heat and humidity that will result in need to curtail activity.

This is being proposed as a model policy for 2013-14.  The MHSAA will monitor school districts’ acceptance of this policy or adoption of similar policies before considering a mandate of this or similar policies.

The model policy will be mandatory for MHSAA tournaments. 

A Hot Topic

July 10, 2012

It is a terrible irony that Georgia saw two of its high school football players die late last summer when it’s the Georgia High School Association that was providing us with the best information we’ve ever had about the risks of heat illness and death.

The deaths occurred in the third year of a thorough three-year study in Georgia that is reinforcing common sense. The study is confirming who is most at risk and when they’re most at risk.

  • Who is most at risk? Linemen more than other players; underclassmen more than older players; those who have had the flu or similar sickness more than others.
  • When are they most at risk? During the season’s first week more than the second. During the second practice of a double session day more than the first. During the second half of the second practice more than the first half, and, early in the morning when humidity is often highest.

It all makes perfect sense: the chubby 9th or 10th grader during the second half of the second practice during the first week of the season. And because it’s statistically predictable, heat illness is almost entirely preventable.

There is some danger here in over-generalizing and over-simplifying, but awareness of these tendencies will help coaches to schedule and administrators to legislate around high-risk scenarios. We expect both will be happening in Michigan.
