Daily body clock patterns and using medicine to treat insomnia

Circadian clock abnormalities may significantly disrupt sleep patterns in various populations.

• Circadian regulation influences sleep-wake states, affecting overall sleep quality.
• Delayed sleep phase syndrome leads to difficulties in falling asleep and waking up at socially acceptable times.
• Advanced sleep phase syndrome results in early morning alertness and evening sleepiness.
• Shift-work sleep disorder presents challenges in aligning sleep schedules with the circadian clock.
• Insomnia may also be associated with alterations in circadian rhythms.
• There is a need for practice guidelines and clinical studies to improve therapy selection and management.
