Abstract in brief

  • Caffeine, the most widely consumed psychoactive substance, is generally found to delay sleep onset, decrease total sleep time and quality, especially affecting slow-wave sleep, with sensitive effects observed in older adults and individuals with specific genetic traits.
  • Most of the research focuses on adult men from Western countries, which limits understanding of caffeine's effects across different populations and ages.
  • Further long-term studies are needed to determine if caffeine-related sleep disruptions have broader impacts on overall health and development, as current evidence mainly shows short-term effects.]

@AukeHoekstra In addition: caffeine can affect sleep in several ways. It doesn't necessarily mean you can't get to sleep, but it can affect the quality of your sleep. You might be more restless, or have a low quality Slow Wave Sleep. https://t.co/MOY4QV37im
