Hot and sweaty, so wear loose cotton, & strategize sight-seeing so you’re not out in mid-day sun. Sri Lanka is incredibly beautiful and cooler at higher elevations. I hired a driver & he showed me about 50 waterfalls, went to 2 tea plantations, and enjoyed the scenery: it was fun.
If we’re used to coastal weather, hot humidity feels like a wall; and our sweat doesn’t evaporate. On hikes or teaching in the heat here in CA, if I start to feel a bit light-headed or dizzy, I drink water and it recirculates: the dizziness shortly goes away. (Those cells near the ear are small, and I get congested from ‘stuff’ in the
air.) When I went to Singapore the first time, I was eager to go to a rainforest reserve, botanical garden, & zoo night safari, but was severely jet-lagged & slow in the humid heat. It’s on the equator. Jeans were too heavy, with raincoat & heavy camera gear. I’d had tempura with soy sauce (maybe a little too much sodium), and was so sluggish, and kept drinking water to re-hydrate as at home;
but unlike home, it stayed on: the hotel scale said I was up 12 lbs. in 3 days! So I made a concerted effort to stay near restrooms & flush the salt out (not easy sight-seeing); and in 28 hours, lost 11 lbs. I’ll never forget it because I don’t bring jeans traveling anymore, just lightweight cotton on top, & loose quick-drying pants for rain and puddle splashes. It’s better to be comfortable on long flights and long walking days.
In Africa, I had malaria, and also lived in Minnesota, so don’t like mosquitoes. They go for the legs and ears.
In Egypt, way hot and dry, my legs ached at night until I learned to put on pajama pants to keep muscles from overly shrinking. In my brain I saw a picture of basketball players putting on warm-up pants as they come off the court hot & sweaty, and thought, ‘Duh.’ The older men I know who complain about their knees hurting all wear shorts, but won’t listen to friendly advice (to try long pants to keep cells from shrinking on cool evenings). It’s a guy thing.
My parents lived in hot 80’s & 90’s F. Brownsville, Texas for 20 years, and my mom used to say she ‘caught cold in the restaurant’ (A.C. 60’s F.). We’d chide her about germ theory, the way offspring are always SO much smarter than their parents.
