Decoding the Mechanism of Sleep Cycles

The human sleep cycle functions like a precise biological clock, alternating between rapid eye movement and deep sleep phases. Interestingly, when we are woken up from deep sleep by an alarm in the early morning, we often feel groggy all day long. This is a typical manifestation of a disrupted cycle. Maintaining a complete sleep cycle is more important than merely extending the time spent in bed, which explains why sometimes sleeping for 8 hours can leave you feeling more tired than 6 hours.

The Circadian Balance of Hormonal Systems

Melatonin acts like the body’s natural sleeping pill, but modern nightlife habits are altering its secretion patterns. I remember during my field research in Norway last winter that locals maintained a regular routine even in extreme night conditions by strictly controlling indoor lighting to maintain hormonal balance. This confirms the key role of managing artificial light sources in regulating the biological clock, which is worth our learning.

Chain Reactions of Disrupted Routine

Clinical observations have found that individuals with disordered routines often experience decreased decision-making ability and emotional management difficulties. A programmer client reduced his coding error rate by 40% after adjusting his routine, vividly illustrating the direct relationship between sleep quality and cognitive performance.
