Dr. Kristen Knutson: The Reason You Feel Tired No Matter How Much You Sleep

Today I explore what chronotype actually means, and why “best” sleep, light and meal timing can look very different from one person to the next. We discuss how chronotype shifts with age, how much is likely genetic versus behavioural, and why it’s difficult to give one-size-fits-all advice without knowing where your internal clock is set. This segment also looks at how chronotype is measured in research and clinics, including why genetic tests are only probabilistic, what questionnaires can tell you, and why dim light melatonin onset is still the gold standard despite being impractical for most people. We also touch on why feeling fine on less sleep doesn’t always match objective performance.
