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. 

Summer Football Safety

July 23, 2018

(This blog first appeared on MHSAA.com on June 23, 2017.)


Across the U.S. this summer, school-age football players are flocking to camps conducted by colleges and commercial interests. They get outfitted in full gear and launch themselves into drills and skills work.

Unlike the start of the interscholastic football season, the players usually do this without several days of acclimatization to avoid heat illness, and without limits on player-to-player contact to reduce head injuries.

Required precautions of the school season are generally ignored at non-school summer camps.

One notable exception to this foolish behavior is found in Michigan where the Michigan High School Athletic Association prohibits member schools’ student-athletes from using full equipment and participating in full-contact activities outside the high school football season. This is not a recent change; it’s been the MHSAA’s explicit policy for more than four decades.

And it’s a policy that has never been more in style and in favor than it is today.
