A simple method for recording and analysing circadian rhythms in man.
We describe a method for recording human rest-activity and body temperature. A small automatic cordless electronic device has been developed in order to record circadian rhythmicity of rest-activity for a period of one week. A comparable device connected to a small temperature transducer by means of a flexible probe was designed to register body temperature. These devices can register human circadian rhythms without interfering with their normal daily activity.
