The invention provides a communication control method of a wearable device, and the wearable device. The method comprises the following steps: when the wearable device is in a water environment, detecting whether the posture of a user of the wearable device is a swimming posture by using a motion sensor, if so, prompting a terminal device that establishes a connection with the wearable device in advance about the current location of the wearable device and the fact that the wearable device is about to close a communication function, and closing the communication function of the wearable device. By implementation of the communication control method provided by the embodiment of the invention, when the user of the wearable device is swimming, the communication function of the wearable deviceis closed to reduce the power consumption of the wearable device.
