identify a breathing state of the user based on the second data.

6. The wearable device of claim 5 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:

identify whether the identified breathing state is a designated state, and

display a notification through the at least one display, based on identifying that the identified breathing state is the designated state.

7. The wearable device of claim 1 ,

wherein the at least one display comprises:

a first display, and

a second display spaced apart from the first display,

wherein the frame comprises:

a first rim surrounding at least a portion of the first display,

a second rim surrounding at least a portion of the second display,

a bridge disposed between the first rim and the second rim,

a first pad disposed along a portion of an edge of the first rim from one end of the bridge, and

a second pad disposed along a portion of an edge of the second rim from another end of the bridge, and

wherein the at least one microphone comprises:

a first microphone disposed in the first pad, and

a second microphone disposed in the second pad.

8. The wearable device of claim 7 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:

identify the second data through each of the first microphone and the second microphone for a designated time from a time point, when the first microphone and the second microphone are each activated.

9. The wearable device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:

obtain audio signals by cancelling noise included in second data.

10. The wearable device of claim 1 ,

wherein the frame comprises:

rims supporting the at least one display, and

temples extending from the rims to be disposed on the other part of the body of the user, and

wherein the PPG sensor is exposed through at least a part of the temples contacted with the other part of the body of the user.

11. The wearable device of claim 1 , further comprising:

an acceleration sensor configured to identify a movement of the wearable device,

wherein the PPG sensor is configured to stop obtaining the first data, based on the movement of the wearable device obtained through the acceleration sensor.

12. A wearable device comprising:

memory including one or more storage media storing instructions;

at least one display configured to transmit light directed to a first surface through a second surface, the second surface facing opposite to the first surface, the at least one display including a display area on the first surface or the second surface;

a frame configured to support the at least one display, the frame including a nose pad;

a photoplethysmography (PPG) sensor disposed in the frame;

at least one microphone disposed in the nose pad; and

at least one processor;

wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:

identify a PPG signal through the PPG sensor, while the at least one microphone is in an inactive state,

identify biometric data of a user wearing the wearable device, based on the PPG signal,

switch a state of the at least one microphone from the inactive state to an active state, based on the biometric data reaching a threshold data,

identify audio signals through the at least one microphone switched to the active state, and

identify a breathing state of the user based on the audio signals, and

wherein a power consumption of the PPG sensor is lower than a power consumption of the at least one microphone.

13. The wearable device of claim 12 ,

wherein the biometric data comprises a change in heart rate of the user, and

wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:

switch the state of the at least one microphone from the inactive state to the active state, based on identifying that the change in the heart rate of the user corresponds to a designated threshold.

14. The wearable device of claim 12 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the wearable device to:
