WebBody temperature is regulated via both autonomic and behavioral thermoeffectors. Current evidence indicates that thermal behavior decreases the requirement for autonomic thermoeffector responses. This suggests that autonomic thermoeffector activation may contribute to decisions to behaviorally thermoregulate. WebThe normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [8] Human body temperature varies.
