>>305118hello fren. fellow southern hemisphere heat allergic wiz here. do research on how to keep your house as cool as possible, avoid sunlight like a plague, and please dont forget to take your vitamin D.
at home, this is all infinitely easier with an AC, but i cant afford one. so here is my routine. i open all my windows at night when the sun goes down, and close them when the sun comes up at 6am. this flushes your place of warmth and slows down heat from seeping in during the day. then i cover all of my windows with tarp from the outside, so sunlight doesnt come in and the tarp doesnt radiate heat inside. i use only one layer of tarp, but my windows still get pretty warm, so ideally you probably need two or three. taking a shower in the late afternoon (when it's usually warmest) will make it slightly more bearable. cook your food in the morning or in the evening, and heat it up in a microwave or eat it cold at noon or the afternoon. if you have to leave, do so as early in the morning or as late into the evening as possible. avoid public transport, especially in the warmest days.
most important of all ALWAYS KEEP TABS ON THE WEATHER. even just mentally preparing yourself for a heatwave will make things easier. plan ahead to do chores outside in the least warm, cloudy days. don't be afraid to reschedule appointments if they land in a day of clear 30C+ weather. whenever it hits 30C or more i know it is one of those days i will just be trying to survive at home and doing nothing else. getting a couple of beers and showering frequently can make things nicer.
good luck on surviving the rest of the summer. our kind would fare a lot better in a place of eternal winter, but that's still a distant dream for both you and me i imagine.
