I always wondered if there was a market for a "cool suit" with astronaut-style cold water tubes all over it you could hook a garden hose up to while working in the yard. Water the grass and cool yourself off at the same time.

There are off-the-shelf cooling vests you can buy. They're basically ice packs and matching pockets to put them in:

Another major manufacturer popularizing these is https://www.qoreperformance.com

You want a furry cooling vest https://www.thedailybeast.com/how-a-cooling-vest-invented-by...

Had to click. Looks like the vest is pretty normie. BYO-Furry-Costume. Interesting nonetheless.

There's been some interesting stuff about cooling the body for exercise performance, and they've found that the soles of the feet, the palms of the hands, and the cheeks are the locations that are most efficient in applying the cooling.

So perhaps just "cool boots" might be enough.

A coworker of mine spent a lot of time maintaining computers in warehouses in the US South and picked up a jacket with basically PC-fans built in, it had sleeves and some of the airflow was down the sleeves. We mostly joked about needing to overclock our field technicians...

We don’t want overclock the field technicians, just avoid them thermal throttling.

With today's hardware there's not a lot of difference. If you keep things cool and maybe unlock a limit or two, you'll get better performance automatically. The parallels seem pretty good :)

I think this type of workwear originated in Japan, where you might find them more commonly used. https://www.thedailystar.net/news-detail-194835

Dirt bike riders/motorcyclists have been pouring water over their clothes/suits and then riding for generations.

Works great to cool down well below ambient air temp as long as humidity isn't super high.

Yeah but actually working while wet will make your clothes chafe the shit out of you.

surgically implanted tubes sounds fun. We could run them though your entire body. Like water holes in cpu's Or perhaps one could repurpose existing tubing.

that's literally your circulatory system

Please be careful when plumbing external connections into the human circulatory system. Several important security mechanisms are bypassed, and there's much more complexity to blood than is initially obvious.

While true, cold saline IV’s are useful for both dehydration and lowering core body temperature.

I want a device that hooks into my circulatory system and diverts my blood flow through it, filtering out microplastics and other shit that shouldn't be there, and then cooling it down slightly before putting it back in.

You want dialysis?

Donate plasma, it works reasonably well. If you have antibodies you want to keep it might be bad though because those count as the plasma and get taken out.

there is more tubing. ice water enema is a thing, drinking cold drinks ofc but perhaps the nasal cavity can be repurposed?

Cooling dialysis?
