Palms and feet and forehead all work better.

Glabrous skin is designed for heat transfer and only located in these 3 spots.

The skin on your wrist does not transfer cold as effectively beneath the skin surface.

Other suggested locations are Neck/arm pits because they are thinner cutaneous skin similar to wrist but the blood flow is direct to your brain.

De-oxyginated blood from your wrist goes to your heart and not your brain and there would be little cooling effect and less benefit then using any of the medically recommended cooling areas.
