Biological clock explains why people wake before alarms
Dr. Amir Khan has explained the biological mechanisms that cause individuals to wake up shortly before their alarms go off. This phenomenon is driven by the body's internal biological clock, specifically a region in the brain known as the suprachiasmatic nucleus, which regulates circadian rhythms.
When a person maintains a consistent sleep-wake routine, the brain begins to anticipate the time of waking. In the hours leading up to the expected wake-up time, the body undergoes several physiological changes: melatonin levels decrease, body temperature rises, and hormones such as cortisol are released. This process is referred to as the cortisol awakening response.
