A sleep dynamic restoration method based on a negative ion concentration, comprising: acquiring a correspondence between a first sleep state of a user in a first predetermined time period before a current time point and a first time point; determining a negative ion concentration adjustment time point according to the correspondence between the first sleep state and the first time point, the negative ion concentration adjustment time point corresponding to the start point of a second predetermined time period before the first time point at the same day; and adjusting, at the negative ion concentration adjustment time point, the negative ion concentration of a scene, where a user is, to a first negative ion concentration corresponding to the first sleep state. According to the method, the user can enter into the first sleep state as soon as possible according to the adjusted negative ion concentration, which means that the user enters into the first sleep state in an earlier state. In the case of the same wake-up time, the sleep of the user can be effectively restored without side effects or dependence on drugs, and adjustment can be performed according to the state of the user, and the method take effect rapidly and is easy to popularize.
