YSK, if you're from a colder climate, visiting southeast asia or any other tropical country, you need to shower twice a day to better cope with the humidity. It always seemed like an obvious thing to me as a SE asian but I was surprised to learn many foreigners don't figure this out sooner. They'll complain so much about the heat, sweat buckets, hog the fans, "cool down" with iced drinks, but it doesn't occur to them to take a shower. Why YSK: Sweat, dirt and oils from our body trap heat, and with humid weather it doesn't dry out as much as you're used to especially if you're from a colder climate, so it traps even more heat, leading to that sticky uncomfortable hot feeling. Plus us locals can smell if you're "unwashed" even from a few feet away so consider it as a courtesy to us as well. Lol.
