What alarming physiological manifestation occurs during the initial 1-3 minutes of cold shock?
Answer
Gasping and hyperventilation
The primary and most dangerous manifestations during the acute cold shock response window are uncontrolled breathing patterns. Specifically, when cold water contacts the face, it triggers the mammalian dive reflex, which demands an immediate, massive, and involuntary inhalation known as the gasp reflex. This is immediately followed by hyperventilation. These events happen within seconds of entry. If an individual is submerged when this involuntary gasp occurs, water inhalation and subsequent drowning is the immediate threat, surpassing dangers associated with prolonged cold exposure.
