The application relates to the technical field of wearable devices, and discloses a health monitoring method and device, a head-mounted earphone and a health
monitoring system. The method comprises the following steps: collecting the current temperature of a user wearing the device by a first collecting component, and determining a temperature change value at the
current time according to the current temperature; collecting health influence data of the user wearing the device by a second collecting component when the temperature change value reaches a preset change threshold, wherein the health influence data comprises at least one of physiological data, electroencephalogram data and a facial image; taking the health influence data as an
influence factor, adjusting the current temperature by the
influence factor, and monitoring the health of the user wearing the device by the adjusted current temperature. Since at least
one health influence data of the user is taken as an
influence factor to adjust the temperature of the user, the measured temperature of the user can be prevented from being disturbed by other factors, so that the accuracy of
health evaluation can be improved.
