The physiological detection device is for equipping on a user, and contains a physiological signal module, an impact module, and a tracking module. The impact module, the physiological signal module, and the tracking module are data-linked to each other. The physiological signal module and the tracking module are also data-linked to at least an alarm module. When the physiological signal module detects some abnormality, an alarm is automatically generated from the alarm module. When the impact module detects some abnormality, an alarm will not be generated immediately. Instead the tracking module monitors the physiological signal module for a period of time. In this way, the false alarm due to that the impact module detects abnormality whereas the user is actually all right. The present invention as such achieves automatic detection and avoids false alarm.
