What does your body clock do?
Your body responds to the daily cycle of light and darkness. Circadian rhythms help coordinate changes over roughly 24 hours.
More than sleep
Circadian rhythms influence sleep patterns, hormone release, appetite, digestion and body temperature. Light and dark are major influences; food intake, activity and stress can also affect daily rhythms.
Start with observation
If you want to discuss your routine, note your usual sleeping hours, work shifts, meals and activity. Bring concerns about persistent sleep difficulties or fatigue to an appropriately qualified healthcare professional.
Science and individual advice
Understanding biological rhythms does not establish the effectiveness of a specific hospital protocol. Recommendations should consider your condition, medicines, responsibilities and care needs.
