Summer is hot, especially if you are being active outdoors. So to avoid getting overheated, I made a simple thermoelectric cooling unit that attaches to your wrist. This is able to rapidly cool your entire body.
You can use this to cool down after a workout or between plays. The unit is small and easily portable. All you need is access to electricity, such as a 12-volt battery.

Peltier coolers are notoriously INEFFICIENT. What a colossal waste of electricity.
Except, they’re working to cool a small portion of your SKIN rather than a large volume of AIR.
The point of this is not to COOL your body, but to fool your body into thinking it doesn’t need the cooling. It’s a psychosomatic effect.
no it really does cool your body. If you cool the blood going into the brain the body doesn’t need to sweat to cool the brain. The brain is the first thing to pop when overheated.
“All you need is access to electricity” i have an electrical car that will go indefinitely all I need is access to electricity…any one has any laying around anywhere?
