If the climate is warm enough the animals actually would need to have ways to actively cool down, like through sweating. Would capturing heat from their expiration still be needed?
- simongr3dal 6y agoWouldn't the mechanism work wether it's warm or cold relative to body temperature? The relative warmness of the breath could be captured on the way out and heat up incoming air, or it could capture the relative coolness of the breath on the way out and cool down incoming air.
