The first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...

You might have heard of cold plunges as a new wellness trend, and there’s science behind how taking the plunge may help ease anxiety through boosting feel-good chemicals like dopamine and other ...
The parasympathetic nervous system in the motor nuclei of cranial nerves III, VII, IX, (control over the pupil and salivary glands) and X (vagus –many functions including immunity) and sacral spinal segments (gastrointestinal and urogenital systems). [12] Another control occurs through top down control by the medial areas of the prefrontal ...

A cold plunge can also induce a heightened state of stress, or send the body and brain into "fight or flight" mode, Colbenson notes. In response to low temperatures, the body will release a surge ...
The vagus nerve (/ ˈ v eɪ. ɡ ə s /), also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that carries sensory fibers that create a pathway that interfaces with the parasympathetic control of the heart, lungs, and digestive tract.
