Episode notes
Sweating: A Human Superpower
- Sweating is a human evolutionary advantage for cooling.
- It allows for running long distances and thriving in hot climates, unlike panting animals.
Alternative Cooling Methods
- Vultures and seals use alternative, less appealing cooling methods like pooping and urinating on themselves.
- Compared to these, sweating is a far superior evolutionary outcome.
Factors Influencing Sweat Rate
- Individual sweat rates depend on genetics and early childhood environment.
- The number of sweat glands (2-5 million) and their flow rate vary, influenced by both nature and nurture.
