Possible there is alayer of air cooled by evaporated sweat within the haired area? Head is known to be a major source of heat exchange in various heat strain situations.<br /><br />Heat balance is determined by about several factors including radiant temp, air temp, air speed, humidity, clothing (& hair apparently), metabolic rate & workload (ie internal heat generated). Water input also. Sun is a source of radiant heat (infrared radiation) and indirectly heats the air ie radiant heat hitting surfaces in contact with air warm it up.<br />Just some quick thoughts.<br />OBAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2467994117916260529.post-29240794779122747232010-08-31T15:40:16.199-07:002010-08-31T15:40:16.199-07:00Makes sense.

I always keep my hair trimmed with #4 clippers in the summer, less sweating and evaporation means hotter body and it has been over 90 degrees for 45 days in a row here, and humidity is high, heat exhaustion is a given when exercising outdoors and heat stroke is a real risk.Anonymousnoreply@blogger.com
