Method and system for sleep reminding based on mobile terminal and mobile terminal

The invention relates to the technical field of mobile terminals, in particular to a method and system for sleep reminding based on a mobile terminal and the mobile terminal. First the heart rate during the sleep is collected; then the heart rate is compared with a preset threshold; and when the heart rate is larger than the threshold, the mobile terminal performs a corresponding awakening prompt. According to the method and the system, whether a sleeper needs to be awaken is judged through the comparison of the heart rate and the preset threshold, and accordingly the harm to lives caused by the sleep apnea syndrome is avoided; and on the conditions that users do not know they have the sleep apnea syndrome, the preventing and reminding effect on the users can be achieved.
