The present invention relates to a device (1) for detecting parameters of a user (3), provided with a wearable support (2) having a first surface (2a) configured for contacting a body surface of the user (3)； the support (2) has a second surface (2b) opposed to the first surface (2a) and comprises a first temperature sensor (10) configured for emitting a signal representative of a temperature at the first surface (2a) of the support (2), and a second temperature sensor (11) configured for emitting a signal representative of a temperature at the second surface (2b) of the support (2). A control unit (19) is configured for receiving as an input the signals emitted by the first and second temperature sensors (10, 11) and for estimating a value representative of an internal body temperature of the user (3) as a function of both the signals emitted by the first and the second temperature sensors (10, 11) and/or estimating a value representative of a room temperature as a function of both the signals emitted by the first and second temperature sensors (10, 11).
