Next time you feel anxious or overwhelmed, science says you can calm your body almost instantly — simply by placing something cold under your arms. This activates the vagus nerve, a key part of the parasympathetic nervous system that controls your body’s natural relaxation response.
When the vagus nerve is stimulated by cold temperature, it signals your heart to slow down, your breathing to steady, and your stress hormones to drop. Within moments, this triggers a state of calm, helping manage panic attacks, anxiety, or sudden emotional stress.
It’s a quick, drug-free way to regulate the body’s stress system. Cold therapy techniques — such as applying ice packs, splashing cold water on the face, or even cold showers — are increasingly being recommended by psychologists for grounding and emotional control.
Sometimes, the body’s most powerful stress relief doesn’t come from medicine — it comes from understanding the science of your own biology.
