A method of wirelessly receiving a biological signal is provided. Thus, it is possible to considerably reduce power consumption of a wireless biological signal receiver by determining a transmission period of an externally received biological signal, setting an operation mode of the wireless biological signal receiver to an active mode in which it is possible to receive the biological signal for a predetermined time for each determined transmission period and receiving the biological signal, and changing the operation mode from the active mode to a low-power mode in which it is impossible to receive the biological signal, after the predetermined time is elapsed with respect to each determined transmission period.
