Hello, it's winter where I am but I understand a lot of the world is experiencing extreme heat. As an Australian who has survived weeks of above 40C temperatures, fires, and prolonged drought I have some advice.

- In dry heat close your house. Close windows, draw blinds. Darkness is your friend. Open at night.
- Heat rises, so keep low if able - downstairs instead of upstairs.
- Use fans / aircon if you have them but prepare for possible electricity outages as demand increases.
- Damp towel over forehead.
- Drink water. Have it with you all the time.
- Stay out of the sun. Remain inside or in shade.
- Wear a hat, sunglasses, sunscreen, light clothing if you do go out.
- Reduce activity. Rest more. Don't go jogging at midday or anything like that. Heat is physically and mentally exhausting.
- Go out if you need to in the early morning or late afternoon / after dark.
- If you can, keep kids home, & work from home.
- If it's still hot at night take a quick cool shower. Sleep is easier at 20C or below.
- Check on elderly & frail. They are vulnerable.
- Let yourself sweat. But keep up electrolytes with sports drinks or medically appropriate hydrating drinks / something like that.
- Your workplace / school should develop an extreme heat policy for health & safety.
- Don't go sight see near fires. Stay away.
- Keep a radio or access to radio stations available for advice from your emergency services / weather / news services.

Same goes for pets. Keep them out of the sun, or inside, with constant access to fresh water. Do not walk dogs on hot streets / hot surfaces / in the sun - if it burns your skin it burns their skin and their feet.

@becadroit
May I add an unpopular one?

- Turn off devices, as far as you can. E.g. fridge on, holidays for dishwasher. Time to rest from computer games.

@becadroit This afternoon I was thinking that the heat wave feels softer when you're on holiday 🤔

@dani You are right! On holiday you can rest more, stay indoors more, and wear what you want. Even if workplaces have air conditioning it's just tiring to go out, do whatever the job requires, and commute. Even in Australia extreme heat delays trains, and sometimes melt roads. Often schools will close too.

@hacknorris Avoid west facing windows / direct sun if you can and be aware hot winds can carry dust or smoke and neither is fun. Damp clothes can work if you are comfortable like that.

@becadroit means - mine rooms arent such and were not having any dusts cause were ALMOST outside of city,so...

@becadroit you clearly don't live in a house like mine. I'll go to work to escape the heat

@Lipk I've lived in all sorts of houses, including ones without air con and insulation, which were not fun. I've gone to work to avoid heat but either started early and left early to avoid crowds, or stayed late to keep cool and also avoid traffic/crowds.

Good luck.

@becadroit Tnx. It's hard when buildings aren't built to keep the heat out. But at least there's some kind of national heat plan for upcoming days, I hope especially elderly people are looked after properly. My parents often mention the '76 heat wave, I was just a few weeks old then so I don't remember. But it's nothing compared to what's happening now 🥵

@becadroit I recall, sometime before I left Facebook in 2017 that I posted under one of many articles I would share "Oh we are going to boil this egg aren't we?" Or something to that effect. And how it was time to move on to coping instead of hoping. Because this generation isn't going to do anything that is far beyond cosmetic. May there be time for me to be wrong, this is all the hope I have left.

@km6ecc Every little thing individuals do is something but governments and industries need to do so much more and much more quickly. Wealthy people think they can escape but we all rely on the environment and nature keeps giving us warnings. Many won't cope - aren't coping now.

@becadroit Ooh, there's heat information on the radio? Can we access that with a standard AM/FM receiver (we have one among all our game consoles) or do we need a special radio for that?

@IceWolf There maybe. In Australia the publicly owned and run radio stations are the emergency broadcasters for fire, flood, and extreme heat advice and are crucial for knowledge of current conditions but even commercial stations run warnings and condition updates. If your government or weather people or emergency organisations have advice for you it's worth getting the information anyway you can, via AM or FM radio stations, govt websites (if they are updated regularly), or live TV.

Also you may need information on public transport, and traffic conditions.

@becadroit @carcinopithecus Checking in from Texas to fully concur on all of this and note that if, like me, you have a serious caffeine addiction cold brew is great and easy and to avoid soda. Water is your best friend.

@becadroit high heat and humidity are absolutely deadly please remember that! When temperature and humidity rise the evaporative cooling effect of sweat drastically decreases until it is non-existent, making dehydration and heat stroke or death much much easier.

@becadroit

"Even if they're in perfect health, even if they're sitting in the shade, even if they're wearing clothes that make it easy in principle to sweat, even if they have an endless supply of water," co-author Radley Horton told VICE News. "If there's enough moisture in the air, it's thermodynamically impossible to prevent the body from overheating."

@theavidhorizon which is why people need to stay where-ever they can where it is even a bit cooler than the expected high temperature. Even if it means sitting in a bathroom in the dark with your feet in a bucket of cold water, or leaving early for somewhere with air con..

@becadroit nothing is as misery inducing as not having cooling during a wet bulb event.

@theavidhorizon Yes thank My advice was for dry heat.

High humidity and high temperatures are just awful. I had to choose between a 47C degree day with no humidity and a 35C degree day with high humidity I'd pick 47C degrees every time because a cool shower & darkness will help.

While closing your home / windows and taking cold showers won't help with humidity.

@becadroit good advice. We need to stop depicting extreme heat with kids running through spray parks and instead like we do hurricanes. No one of the right mind os flying a kite with a hurricane looming.

@chad my only caution is this advice is for dry heat. High humidity / tropical conditions in high temperatures are very different.

But yes no kite flying in hurricanes, no sunbathing in extreme heat or actually ever at all, really.
