Walking through water reduces the temperature of the pawn.

Ive read about how tribals have some issues with heat waves. So I thought a decent solution would be to have the various pools of water that can be found on map cool down pawns that walk through it or stand in it.

This could also lead to a new joy activity: relaxing at the pond/shore/beach

Smart. To take it further, perhaps primitive encampments could dig a wading pool or something.

Sounds like a good idea ... it makes sense and, in contrast to drinking water mechanics, doesn't add too much micromanagement or development burden
