Circadian rhythms are a biological version of a computer/clock which are endogenous/exongenous. This means that they are generated from outside/within the body. Circadian rhythms are found inside most living cells, plants, animals and humans. Their origin dates back 3.5 billion years. Rhythms are a response to the most predictable condition of life on earth, cold/dark at night and light/hot in the day. One example of a circadian rhythm is the sleep-rest/wake cycle. use of daylight hours and It has evolved to promote the best rest/energy in the darkness when cell/mental reparation and personality/memory adjustment can be carried out for the next day. Daylight regulates the clock, and modern research has looked at the effect of bright/artificial light on humans and how far that may disrupt our sleep and health. Circadian means a full day/almost a day is a biological process which is driven by an internal oscillator which can persist and alter as the periodicity of light and dark change, i.e.as days get shorter in the winter/summer. 1 2 3 4 5 6 NOTE: This is a deep-dive into one example of an ultradian rhythm-THE SLEEP CYCLE- which will help with the later topic THE NATURE OF SLEEP and RESEARCH METHODS 2 DESIGNING AND REPORTING PSYCHOLOGICAL INVESTIGATIONS 7 8 9 10 11 12 13 The Nature of Sleep This topic has already been introduced in biological rhythms in the learning of ultradian rhythms and sleep cycles including Dement and Kleitman’s pioneering research.
