Outline and Evaluate Research into Circadian Rhythms A circadian rhythm is a biological rhythm that occurs over a 24-hour cycle. For example, the sleep/wake cycle; we are at out most alert at 10am, we have the best coordination at 2:30pm, out fastest reaction time is at 3:30pm, and our deepest sleep is at 2am. Our circadian rhythms occur due to light and melatonin. Light sensitive cells in our eyes send messages about the levels of light, in our environment to the suprachiasmatic nucleus. T...
