Are you a morning lark or night owl? Here's how your body clock works
Whether you’re a morning person or love burning the midnight oil, we’re all controlled by so-called “body clocks.” These body clocks (which regulate your circadian rhythms) are inside almost every cell in the body and control when we feel awake and tired during a 24-hour period. But as it turns out, our latest study found that our body clocks have a much bigger impact on us than we previously realised. In fact, our body clocks actually effect how well a person performs on both mental and physical tasks . Our circadian rhythms are controlled by the brain’s suprachiasmatic nucleus, which detects light. When cells in your eyes register that it’s dark outside, they send these signals to the suprachiasmatic nucleus. It then releases the hormone melatonin, which makes you feel tired. Your chronotype is another factor that determines how your biological clocks affect your daily behaviours. For example early chronotypes (“morning larks”) rise early and are most active in the mornin
