👉 Hiking fumes, also known as "hiker's cough," are a common phenomenon experienced by people who spend extended periods outdoors, especially at high altitudes or in humid conditions. These fumes are primarily caused by inhaling volatile organic compounds (VOCs) and other irritants released from the moisture absorbed by clothing, gear, and even the ground itself. As the body tries to expel these irritants, it triggers a cough reflex, leading to a persistent, dry hacking sensation in the throat. This reaction is exacerbated by the natural increase in breathing rate and depth during physical exertion, making hiking fumes a notable and often uncomfortable experience for outdoor enthusiasts.
