    Sudden immersion in cold water causes a significant increase in breathing (ventilation) and a drop in alveolar carbon dioxide. This response may increase drowning risk by impairing swimming and leading to water inhalation.

    Area of Science:

    • Physiology
    • Environmental Medicine
    • Drowning Research

    Background:

    • Cold water immersion is a known risk factor for drowning.
    • The physiological responses to cold water, particularly concerning ventilation, require further investigation.

    Purpose of the Study:

    • To investigate the relationship between cold stimuli and ventilation during water immersion.
    • To measure breath-by-breath ventilation and alveolar PCO2 in response to cold and warm water immersion.

    Main Methods:

    • Eight male subjects were immersed in cold (11°C) and warm (28°C) water.
    • Measurements included breath-by-breath ventilation and alveolar PCO2.
    • Data were collected during the initial breaths and after 5 minutes of immersion.

    Main Results:

    • Cold water immersion led to significantly higher ventilation rates compared to warm water, particularly in the first three breaths (e.g., 94.5 L/min vs. 60.0 L/min).
    • Alveolar PCO2 decreased sharply in cold water (from 36.4 to 23.9 torr) but showed minimal change in warm water.
    • Elevated ventilation persisted in cold water even after 5 minutes.

    Conclusions:

    • Cold water immersion triggers a pronounced hyperventilatory response.
    • This exaggerated ventilation, coupled with potential swimming impairment and water aspiration, likely increases the risk of drowning in cold water environments.
