The invention is applicable to the field of medical apparatuses, and discloses a wireless portable human health and sleep quality monitor, which comprises a sensor module, a central processing unit, an output module, a wireless communication module, a power module and an upper computer. The sensor module is electrically connected with the central processing unit. The central processing unit is used for receiving and processing physiological signals acquired by the sensor module and, at the same time, controlling the sensor module, the output module and the wireless communication module to operate. The wireless portable human health and sleep quality monitor disclosed by the invention can detect the physiological signals of a monitor wearer, such as electrocardiosignals, respiratory signals, body temperature signals, blood oxygen signals and posture signals, in real time, make an assessment on the health and sleep quality of the monitor wearer by assessing and analyzing the physiological signals and upload data to a cloud wirelessly or via the Internet, so that medical workers can conveniently give reasonable suggestions to the wearer.
