What sleep optimisation involves
Programmes assess sleep duration, regularity and quality — sometimes with tracking or screening for disorders such as sleep apnea — and apply behavioural changes (fixed wake time, light exposure, sleep hygiene) and, where needed, medical treatment.
Evidence and what to consider
Sleep is strongly tied to mortality and healthspan: large studies link consistently short sleep to higher mortality, and a regular schedule is a high-leverage, low-cost intervention. Look for clinics that screen for treatable disorders (such as apnea) rather than only selling gadgets, and that prioritise behavioural fundamentals.
