1. A wearable device comprising:
memory including one or more storage media storing instructions;
at least one display, when the wearable device is worn by a user, positioned in front of eyes of the user;
a frame configured to support the at least one display, the frame including a nose pad contacted with a part of a body of the user, when the wearable device is worn;
a photoplethysmography (PPG) sensor in the frame, contacted with another part of the body of the user, when the wearable device is worn;
at least one microphone; and
at least one processor including processing circuitry,
wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:
while identifying a respiration of the user wearing the wearable device, through the at least one microphone, is deactivated, identify a first data associated with the respiration of the user through the PPG sensor, and
based on the first data reaching threshold data, activate identifying the respiration of the user through the at least one microphone for identifying second data associated with the respiration of the user.
