1. An electronic device comprising:
a memory configured to store instructions;
an RF sensor configured to transmit a Radio Frequency (RF) signal and receive a reflection signal of the RF signal; and
at least one processor coupled to the RF sensor and the memory and configured to execute the stored instructions in order to:
identify one or more signals indicating a state of a user within the received reflection signal,
monitor a change in data determined based on the one or more signals according to a time,
determine that a time point at which the user actually begins sleeping is a first time point at which the monitored change is smaller than a first reference value,
determine that a time point at which the user intends to sleep is a second time point at which the monitored change is larger than a second reference value,
determine that a sleep latency of the user is a time interval between the first time point and the second time point, and
store information on the determined time interval.
