Coping with heat

The freezer gel packs certainly last a good long while, I use them for my back pain. The issue I have is out of the freezer they are far too cold to be touching skin, you have to wrap them first with a tea towel once or twice. The bricks I have but have only really ever used for chilling purposes not on my body but they tend to last all day in a chill box so they also hold a fair bit of (deficit of) energy.
 
The chill boxes are insulated, which is why the bricks last a long time in them. The important question is how much energy it takes to get them back to room temp, and that’s not very much, so they won’t last for long in a normal room.
 
The thing for me is that I want to be able to apply the cold packs behind my neck, back and knees when I lie down. This cools my whole body down quickly. You can't do that with a hard block.

Have you looked at reusable cold packs for sports? They can often be bent, which probably makes them more comfortable than bricks.
 
This is cool, literally.

This paint 'sweats' to keep your house cool

A new cement-based paint cools buildings by combining sunlight reflection and water evaporation

Scientists in Singapore have developed a new type of paint that reflects sunlight and cools surfaces by slowly evaporating water. Unlike other commercially available cooling paints, which are designed to repel water to protect the underlying material, the new one even works in hot, humid places, offering a low-energy way to stay cool, researchers report June 5 in Science.
