Students with climate sensitivity might have adverse reactions (e.g. arthritic pain) to changes in weather elements such as air pressure, temperature, or humidity; climate sensitivity also includes students whose disability makes it unsafe for them to spend extended time in extreme temperatures.

Some students may not feel the warning symptoms of frostbite or hypothermia; students with conditions that inhibit their body's ability to regulate temperature; or students whose conditions may worsen in extreme heat or cold (e.g. multiple sclerosis, breathing disorders).
