Here are some tips on how to keep yourself cool and comfortable:
1.) Turn on the air-conditioner (Be prepared to pay some hefty electricity bills)
2.) Buy & consume Cheng Teng from the wet market (Be prepared to pile up on the calories)
3.) Drink lots of iced water/iced lemon tea/iced green tea (Any iced drink will do)
4.) Avoid going out too often (Good news for introverts!)
5.) Shower at least twice a day (Who cares about saving water?)
Or, for the extreme, immigrate to the North/South Pole :)
