Simple Ice Water Trick to Calm Nerves: Doctor Explains the Science

A simple way to calm your nerves: Submerging your face in ice water for 5-10 seconds can trigger the mammalian diving reflex, which slows your heart rate and reduces oxygen consumption, according to Dr. Mihail Pautov, a general surgeon. In his recent TikTok video, Dr. Pautov explains this technique, which involves filling a bowl with cold water and ice, then submerging your face for 5-10 seconds. 'This triggers the diving reflex, which activates your vagus nerve, responsible for your parasympathetic nervous system,' says Dr. Pautov. 'It will cause bradycardia, apnea, and increased peripheral vascular resistance, redirecting blood flow to the heart and brain.' While the video promotes a coffee brand, the core message about stress reduction is valuable and could easily be adapted into a health-focused article. Many people may find this simple technique useful for managing stress and anxiety.
