In moderate hypothermia, the absence of corneal reflexes is typically noted below 82.4°F (28°C). This physiological response can occur as the body temperature drops significantly, leading to a depressant effect on the central nervous system. At lower temperatures, neurological functions may begin to decline, which includes both cognitive and reflexive responses. The corneal reflex, which is a protective mechanism of the eye, may be affected as hypothermia progresses, signaling a deeper level of temperature-induced impairment in nervous system function.

Understanding these temperature thresholds is crucial for healthcare providers when assessing patients with hypothermia, as neurological status and reflex responses can provide important indicators of severity and required interventions. The identified temperature of 82.4°F marks a critical point where reflexes start to diminish, highlighting the importance of monitoring core body temperature in individuals exposed to cold conditions.
