I might have been a tad harsh earlier so just take it easy, wear loose light clothes, have a water bottle close, wear a hat, find the coolest place inside, put ciggies out completely if you have to smoke, sit down for a minute, take a half step off your pace, look out for people, be aware of any changes in your soundings due to heat, enjoy complaining about it and laugh about how its completely the oppostite of whatever the weather usually does, buy a decent fan, even one of the little floor ones are great, dont go out during the hottest time of the day and wear deodorant you dead set stinkers.
