It's the same principle the nomads in the desert utilize; the hottest you can get under a well insulated layer of clothing is your body temp of 98.6,  while leaving yourself exposed to temps higher than your body heat causes your body temp to go higher, sometimes with deadly results.

Desert nomads wear loose clothing that is thick enough to block sunlight but no thicker.  
You can get hotter than 98.6 if you over-insulate yourself.
Desert air will not overheat your body because the dew point is very low.  So you want that kind of air taking your sweat and respiration away.  What you don't want is the sun heating your body up.
This goes back to the real danger of global warming.  Today, in the early summer months, parts of the Indian subcontinent get a dew point that is very close to human skin temperature. If the dew point equals human skin temperature, sweat never evaporates and the human body can't cool itself.  So if warming trends continue, the dew point will meet or exceed human body temperature and people will die unless they all get AC. Remember, dew points are typically similar both day and night, so moving activities to night time wont help.  It's hundreds of millions of people all living in an area that may soon be uninhabitable.
