Okay, you know what? Given that over the last week I have seen at least one of the common myths of "things you should not do in the heat" come over my dashboard, let us quickly go over this:
If it is hot, you will need to drink more than normally because you are sweating. You can drink too much, though usually your body knows how to regulate it.
Yes, if it is liquid and not alcoholic it counts to your drinking intake. Yes, drinking lemonades, coke and whatever counts. All of it is still mostly water with some sugar and flavors added. It is fine. Be careful about taking in too much caffeine though, as it is a mild diuretic (means it makes you pee more and hence lose more water).
Yes, you also need electrolytes as you sweat them out. But you do not need to drink sports drinks. Eat some yoghurt with fruits, or some watermelon with salt, or maybe cold soup. It will refill your electrolytes.
No, it is not dangerous for you to sleep in front of a ventilator. This is a complete myth that has absolutely no basis in science whatsoever and literally originates with an Urban Legend. Especially with the recent heat wave in Europe for a lot of people the alternative is the possibility of heat stroke. It is fine. Sleep in front of that ventilator. Just make sure you are not getting too cold.
No, using sunscreen does not stop you from taking in Vitamin D, unless you are permanently using super high standard sun screen and are reapplying it every 6 hours as intended. And let's face it: you are not. Your skin gets enough UVB to make Vitamin D, don't worry about it. Skin cancer is worse.
Yes, switching between a very hot outside and a very cold context (be it super high AC or just jumping into cold water) can be a danger for your cardiovascular system, though unless the weather is very hot or the water very cold making the contrast very extreme, it is normally not a danger to people who do not have otherwise issues with their cardiovascular system. Though being a bit careful and allowing yourself to acclimatize is not a bad idea in general.
Yes, you should definitely not leave any living thing in a car while it is hot. Just don't. Cars heat up while standing very quickly and will become a death trap. If you leave an animal or a child alone in the car for even just 5 to 10 minutes, they might die. Don't do that shit.
Yes, you need to be extra careful about your medications. For once, most medications are not meant to be stored at above 25°C (don't ask me what this is in American units). But also a bunch of medications - especially psychoactive medications - will make your body worth at temperature regulation. So be careful.
Yes, you need shadow. Ideally the shadow of trees, because there is indeed a difference between that and the shadow of a building. But any shadow is good, especially during extreme heat.
In the same vein: be also careful about drugs during heat waves - like, the recreational type. Some of them work differently when your body is warmed up like that. Just... ideally read up online on possible side effects that might occur/be worse if taken during the heat.
Generally speaking: stay hydrated. Stay cool. Try to do it as well as you can in your respective situation. Stay safe.
