The invention discloses a sleep staging method and related equipment. The sleep staging method includes the steps that firstly, a first electrophysiological signal of a forehead area of a user in thesleep process is collected; then a sleep physiological signal is extracted from the first electrophysiological signal, wherein the sleep physiological signal comprises at least one of a first electroencephalogram signal, an eye electrophysiological signal and an electromyographic signal; according to the sleep physiological signal, a sleep staging result of the user is determined, wherein the sleep staging result is used for evaluating the health state of the user. By means of the sleep staging method and the related equipment in the embodiment, the sleep staging accuracy can be improved.
