The research
A study published in JMIR Formative Research explored the effects of cold therapy on relaxation and heart function. The study included 61 participants who received 16-second bursts of cold stimulation on the neck, cheek, and forearm. Heart activity was monitored using an electrocardiogram, a medical test that records the heart’s electrical signals.
The results
Researchers found that when a cold stimulation was applied to the lateral neck region, the parasympathetic nervous system was activated. This system controls the body’s “rest and digest” response, helping you relax and recover from stress. By triggering this system, cold therapy can help reduce stress and support a calmer state of mind.
