Stress in Sport Horses: Causes, Effects, and Effective Solutions
Stress in sport horses can have both physical and mental effects, impacting their performance and well-being. There are two types of stress: acute stress, which is short-term (such as during transportation or warm-ups at competitions), and chronic stress, which persists over time and can lead to stable vices, reduced focus, and health issues like weakened immunity and gastric ulcers. Addressing the causes of chronic stress, such as lack of exercise or abrupt routine changes, is key to maintaining optimal performance. Solutions include a stable living environment, proper management, and supplements like DH Tranquillity to help horses relax without becoming over-stimulated.

Stress in Sport Horses: Causes, Effects, and Effective Solutions
Sport horses are regularly exposed to stressful situations such as transport, competitions, and intensive training. Stress can significantly impact their performance and well-being, leading to both physical and mental consequences. When a horse experiences stress, the body produces the hormone cortisol. This can affect behavior, focus, and health. We distinguish between two types of stress: acute and chronic stress.
Acute Stress
Acute stress is a short-term form of tension that occurs during events like a visit to the vet, transportation to a competition, or warm-up sessions at shows. Your horse might startle or feel tense, but generally recovers quickly. This type of stress is usually unavoidable and has no long-lasting negative effects as long as the horse can recover properly.
Chronic Stress
Chronic stress occurs when stress persists over a long period. It may result in stable vices such as cribbing or weaving, reduced focus during riding, and an increased risk of injuries. The causes are diverse: loneliness, insufficient movement, poor-quality forage, intensive training schedules, or abrupt changes in routine. It’s essential to recognize and address these causes to maintain optimal performance.
Effects of Chronic Stress
Long-term stress can negatively affect your horse’s performance and health. Looking for a solution? Discover the best supplement for stress in horses to help your horse relax.
- Reduced Immunity: A prolonged increase in cortisol levels can lower the production of white blood cells, making your horse more vulnerable to infections and diseases.
- Sensitive Stomach: Stress can reduce blood flow to the stomach, leading to a sensitive stomach lining and issues like gastric ulcers, which are common in sport horses.
- Disrupted Gut Function: Horses under stress often experience loose stools due to an imbalance in their gut flora, which can negatively affect nutrient absorption—critical for performance horses.
- Sugar Sensitivity: Ongoing cortisol production can disrupt sugar metabolism, causing your horse to store fat more easily and increasing the risk of insulin resistance.
How to Reduce Stress
The foundation for a relaxed sport horse lies in a stable living environment and good management. Ensure sufficient turnout, controlled exercise, high-quality forage, and social contact with other horses. Gradually implement changes and minimize stressful situations related to transport and competitions.
