According to an embodiment, an electronic device includes: a photoplethysmography (PPG) sensor, a temperature sensor, a memory, and a processor. The processor is configured to store first information on blood flow of a user, as associated with second information on temperature of a part of the user's body. The processor is configured to change a state of the temperature sensor from active state to inactive state. The processor is configured to identify that a first value representing the blood flow of the user is out of a first range. The processor is configured to change the state of the temperature sensor from the inactive state to the active state. The processor is configured to, based on identifying that a second value representing the temperature of the part of the user's body is out of the second range, provide a notification.
