30 THE BODY CLOCK Yes, this really is a thing! Your circadian rhythm can be thought of as a cycle of established events working in the background of your brain, but it’s the complex action of nervepathways in response to light that ensures they occur like clockwork. Exposure to light stimulates a nerve pathway from the retina in the eye to an area in the brain called the hypothalamus. ere, a special centre called the suprachiasmatic nucleus (SCN) works like a clock that sets off a regulated pattern of activities that affect the entire body such as the regulation of body temperature, heart rate, blood pressure and the release of hormones that help us to sleep.
