Perhaps try leaving a few sets of smarts in the office drawer, for the occasional day when it isn't so hot & humid and do the cycle just a couple of times a week. You will notice a difference :)
Exactly: remember Don Draper in Mad Men? Pile of crisp shirts in the desk drawer for those occasions when he'd stayed out all night & had to look presentable the next day.
(Not saying you should emulate DD otherwise mind!)
