    Here is a graph from a medical journal article that looks at the environmental conditions above which most football players can no longer keep their core body temperatures from rising uncontrolled. The three lines represent (from lower left to upper right) practice in full uniform, practice in helmet and pads, and practice in t-shirt and shorts. Simply take the day's relative humidity and temperature and intersect the two to see if the line intersects above or below the line that applies to you.
