Seen this response on more than one horse...

The parasympathetic nervous system (PNS) plays a crucial role in regulating the 'rest and digest' state in horses, facilitating recovery, relaxation, and overall well-being. Equine energy work, such as therapeutic use of tuning forks, targets this nervous system component to encourage parasympathetic activation, which can result in reduced stress levels, improved circulation, and enhanced healing processes. Tuning forks emit specific sound frequencies that may influence the horse’s bioenergetic field, promoting balance and calming the nervous system. When applied correctly, these vibrations can stimulate the PNS, thereby helping horses to release tension and improve their physiological responses to environmental and physical stressors. This type of therapy is part of a broader category of equine therapy approaches that integrate natural and non-invasive modalities to support animal health. Besides energy work, techniques such as massage, acupuncture, and chiropractic care also contribute to enhancing parasympathetic tone. Understanding and observing PNS responses in horses during therapy sessions is essential for practitioners aiming to tailor treatments effectively. Signs of parasympathetic activation in horses include lowered heart rate, droopy lips, relaxed posture, and slower, more rhythmic breathing. Continuing research into the benefits of equine energy work and other complementary therapies expands our knowledge of how to best support horse health, performance, and recovery through nervous system modulation. Horse owners and therapists are encouraged to combine traditional veterinary care with these holistic methods to optimize outcomes for equine well-being.
