Cold water immersion can cause memory loss. A young volunteer experienced transient global amnesia during a cold-water experiment, even with core temperatures above 35 degrees C.

Area of Science:

  • Environmental Medicine
  • Neuroscience

Background:

  • Cold-water immersion is a common practice for recreation and therapy.
  • Understanding the physiological effects of cold exposure is crucial for safety.

Observation:

  • A volunteer underwent three 120-minute immersions in 20°C water within a single day.
  • During the third immersion, transient global amnesia occurred between minutes 95 and 115.

Findings:

  • The subject's rectal temperature was 35.6°C during the amnesia episode.
  • This case suggests memory loss is possible after cold-water exposure at core temperatures above 35°C.

Implications:

  • Highlights potential neurological risks associated with prolonged cold-water exposure.
  • Suggests the need for further research into the relationship between core body temperature and cognitive function during cold stress.
