Horses can smell fear in humans, researchers say

Researchers have found that horses can detect fear in humans, as evidenced by tests showing that horses exposed to body odour from individuals watching horror films startled more easily and exhibited higher heart rates compared to those exposed to odours from people watching joyful scenes.

This discovery has significant implications for riders, trainers, and others who interact with horses, suggesting that human emotions can influence equine behavior and may affect training and handling practices.
