I wear long sleeves and long pants to avoid sunburn plus a hat. More clothes may be hotter but it's better than sun burn or sun stroke. The Thailand golf caddies are covered head to toe. They don't want to turn dark even though they tan well. As a fair skin foreigner the sun is my enemy. The Asian respect for the sun was obvious my first trip to Thailand over 30 years ago when most locals on the street used umbrellas to protect them from the sun. Umbrellas in Thailand are just as popular without rain. I use a big golf umbrella in Thailand on sunny days when I'm out doors.
Your video was rich in good anecdotal advice about time of day, staying hydrated, cooling before attempting sleep..., but the issues are indeed serious. Some of your advice is wrong during conditions of high heat and humidity. (e.g. cold liquid confuses our internal thermostats, Cool is refreshing without making your body think it need not sweat.) I had posted this link to the CNN article, noting: CNN posts this: "While some people are more vulnerable to heat than others, including the very old and young, no one is immune - not even the world’s top athletes. Many are expressing anxiety as temperatures are forecast to soar past 95 degrees this week in Paris, as the Olympic Games get underway." After reporting how heat affects our skin, heart and brain: "Heatstroke happens when your body can’t use its usual tricks to cool down, like sweating and increasing blood flow to your skin, leading to a catastrophic rise in core temperature. Once your internal body temperature starts to climb above 104 Fahrenheit, which can happen within 10 to 20 minutes of exposure, “you’re moving toward death, and it can creep up on you very, very quickly,” said Bailey. " Near the bottom of the article is an animation as to what places will become uninhabitable without AC (unavailable to many, so expect mass migration too) "Heat already kills an estimated 489,000 people each year, according to the World Health Organization, but the real toll could be higher because heat-related deaths are so hard to track." • edition.cnn.com/2024/07/29/climate/heat-survivability-health-death-intl/index.html Back to what concerned me about cold drinks during high heat. The world is changing, getting seasonally hotter and power grids are going to be stressed more, fail more often. In such future events, opening the fridge to extract a cold drink would not be your best strategy. It certainly is not the optimal way to avoid heatstroke when temperatures are 44ºC (111ºF) The reason is that evaporation (primarily sweating) sucks away far more (5.4 times as much) heat energy than warming cold water in your body, so you need to keep the sweat process functioning, not turn it off by cold water in the stomach. Remember that people die from diseases when their fever gets too high. The same 40ºC (104ºF) that kills from disease is the same internal limit that kills by heat stroke. A damp towel over the head or around the back of the neck is what people need to do if their surroundings are too hot for too long. With such, a fan or a breeze helps greatly. Adding water externally to your T-shirt reduces the stress of sweating - conserving electrolytes. The advice varies by the severity of the heat and humidity. But, even a healthy young athletic person will still die if their body can't shed its metabolic heat and their core temperature gets to a killer fever level.
I can think of nothing better than a long drink of cold water on a hot day. Some people say that eating ice cream might shorten my life by 5 years. If I can't eat ice cream then I won't need those 5 extra years. A bowl of ice cream and a glass of ice water, and I am already in heaven. We have planted over 250 trees on our land so I think that balances out my carbon footprint when I use my refrigerator.
My comment was not about your carbon footprint. The advice is about how the human body responds to cold food and drink, especially if a person has become overheated and is sweating. The sweat cools your body more effectively. The cold food or drink shuts that response down, potentially when you need it the most. Let the sweating taper off , and if/when it does - that is the time to enjoy your ice cream.

You're doing it right. Yeh, the caddies have these hats with huge brims and neck protection.

Turn the air on if you are hot. Isn't it obvious.
Everyone has their own way of dealing with the heat. BTW, how much is your electricity bill?
