A monitoring and regulation method and apparatus based on a human body multimode signal. The apparatus comprises a sleep regulation bed (1), and a sleep monitoring module (2) and a sleep regulation module (3) that are disposed on the sleep regulation bed (1). The sleep monitoring module (2) is used for obtaining physiological signals and performing analysis according to the physiological signals to monitor a sleep state, wherein the physiological signals comprise an electroencephalogram signal, an electrocardiogram signal, an electrooculogram signal, a respiration signal, a body temperature signal, and a body movement signal; the sleep regulation module (3) is in signal connection with the sleep monitoring module (2) and is used for outputting, according to the monitoring result, regulation parameters for regulating a sleep environment. The apparatus can not only detect the sleep state and classify the sleep quality, but can also implement regulation by targeted means such as micro current, light, temperature, and somatosensory massage, so as to help a user improve the sleep quality.
