Infrared therapy has established itself as a valuable tool in equine physiotherapy. But how exactly does it work in the horse's body? The key is the deep penetration of IR-A rays (700–1400 nm), which can penetrate several centimeters into the tissue. There, they exert several therapeutically effective effects:
-
Promotes blood circulation : The generated deep heat leads to the widening of blood vessels (vasodilation) and improves the supply of oxygen and nutrients to the treated tissue [1].
-
Cellular effects : Activation of mitochondria increases ATP production in cells, which boosts cell metabolism and accelerates healing processes [2].
-
Muscle relaxation : The heat reduces muscle tone and helps to relieve tension [3].
-
Lymph activity : The removal of metabolic waste products is stimulated, which has an anti-inflammatory effect [4].
These processes make infrared therapy a gentle yet effective support for regeneration and prevention.
