5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

I never knew that was a thing - crazy.
I don't understand why anyone would think taking a motorcycle ride through 130F temps is a good idea.
It doesn't even sound like a fun idea!
But I hate the heat.
It's a terrible idea, having been a biker in socal. You'd think ventilated fabric, even a regular t-shirt with air moving on you from your forward motion would cool you..
It doesn't. You're actually adding heat (thermal energy) to your body faster than it can be removed by your sweat glands, the glands cannot output water fast enough to match the thermal energy being injected into you as the hot air passes over your body. You actually need to insulate yourself with a wind blocking jacket, at which point fuck that, stop riding, and wait a few hours.
It's a very odd sensation, but you understand it almost without explanation if you've tried it... So what were these guys thinking, ignoring their body's alarm bells?
Once the ambient temperature matches your body's temperature, it's game over for your physiological cooling system.
Not exactly. If it's not humid, you can still shed heat through sweating. Evaporation is an endothermic process. It's a physics equation involving primarily temperature and humidity, but also radiant heat and wind speed. Measuring the wet bulb globe temperature directly is usually easier.
You have to have wet bulb temperatures approaching body temperature for it to actually become lethal - you can still lose heat through perspiration if the humidity is not high enough.
Ambient temperatures of 36-37 C don't immediately mean game over.
As long as you have enough water to keep sweating and you know, survive.
Naturally. If you don't have enough water to sweat then you're in trouble at pretty low temperatures in relative terms.
That's not true, otherwise Phoenix would be unlivable. It's close, but not quite there yet.
I heard it’s not even the core temperature but actually pretty low. When I remember correctly it’s around 34C. That’s a Temperature even we in Europe will experience in summer regularly.
AFAIK the second best thing to do when it’s really hot and you’re on a motorcycle is: Make your underwear wet with water and put on your outer layer as insulation. The water will evaporate through your clothes and prevent the body from creating too much sweat which will cause dehydration. Repeat when you get dry.
The best thing ist to not ride a motorcycle for long periods of time under these conditions. I would maybe commute for up to an hour but never ever go touring when the temperatures reach 40C. It’s just too damn hot and you need more water then petrol
High humidity can screw your cooling too, even at lower temperatures.
