Physiological response to low temperature
WebbThirteen nonheadache cohorts served as a control group. For the migraine group, analyses of variance revealed significantly warmer head and hand temperatures and lower frontal EMG. Range-corrected data, which allow comparisons among the physiological measures, showed the migraine group to have a more stereotypic response pattern across tasks. Webb5 mars 2024 · Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C). When your body temperature drops, your …
