I know right? I learned this while travelling and from living in the south of Spain. We also don't end showering with cold water. End your shower with a hot burst. Same reason as the beverages. If you shower cold you're dropping your body temperature. When you step outside the shower your body tries to adjust to the outside temperature - you sweat again.

Another one is multiple layers of clothing to protect you from the sun hitting your skin. Ever wondered why Arabian woman walk around in black? They're wearing multiple layers and the black absorbs the heat while the layers underneath keep them cool.

Weird how some stuff works...
