Have you ever walked in a barn, and felt like your lungs were being assaulted? Imagine how a horse feels, particularly if they spend hours in a stall. When horses exercise, they take on upwards of 16 times as much air per second than their human owners. Their lung capacity is enormous, as are their athletic capabilities, unless they are compromised by environmental factors. Much can be done from a management standpoint to minimize dust and harmful particulates in a horse’s environment while maximizing athletic function and general comfort in the process.
