Sleep needs change
Sleep needs vary between people and across the lifespan. Reference ranges are useful, but persistent sleep problems or marked daytime sleepiness deserve professional assessment.
HEALTH INTELLIGENCE · KNOWLEDGE
Sleep and recovery: more than counting hours.
Healthy sleep is more than a number on a smartwatch. Duration, quality, regularity, daytime activity and individual symptoms need to be considered together.
Tracking is a signal, not a diagnosis
Wearables can show trends. Individual scores and estimated sleep stages should not be treated as medical diagnoses.
Recovery is broader than sleep
Workload, movement, stress, nutrition, alcohol, medicines and health conditions can all influence sleep and recovery.
