Cold air is dry, dense, and irritating to the equine respiratory system. When horses inhale freezing air, especially during work, it can stress the lungs and reduce their ability to clear mucus and debris. Here’s how to support respiratory health through winter:
🔹 Ventilation is non-negotiable
Closing barns tightly to “keep warmth in” traps ammonia, dust, and mold spores. Poor air quality irritates the airways and increases the risk of coughs and inflammation. Fresh air, even in winter, is healthier than stagnant air.
🔹 Reduce dust at the source
Winter often means more time indoors and more exposure to hay and bedding dust. Soaking or steaming hay, feeding from ground level, and choosing low dust bedding help protect the delicate lung tissue.
🔹 Adjust work for cold air
Cold air causes the airways to constrict. Longer warm ups at the walk allow the respiratory system to adapt before asking for trot or canter. On extreme cold days, lighter work or rest may be the kindest option.
🔹 Support thermoregulation
When a horse is cold, their body prioritizes staying warm over optimal lung and immune function. Appropriate blanketing helps conserve energy and reduces overall physiological stress.
🔹 Hydration supports airway health
Dehydration thickens respiratory mucus, making it harder for the lungs to clear particles. Offering warm water and monitoring intake is especially important in freezing temperatures.
Healthy lungs = better oxygen delivery, recovery, and resilience.
