Sleep-wake cycle

The sleep-wake cycle is the natural rhythm that regulates when we feel alert and when we feel sleepy, typically following a 24-hour pattern. It is influenced by various factors, including light exposure, which signals our brains to produce hormones like melatonin for sleep and cortisol for wakefulness. This cycle is essential for our physical and mental health, promoting recovery, memory consolidation, and overall well-being. Disruptions, such as shift work or excessive screen time before bed, can lead to sleep problems and affect daily functioning. Balancing this cycle is crucial for maintaining energy and focus.
