Topic guide

Sleep and recovery

Evidence checks about sleep, insomnia, melatonin, trackers, circadian health, recovery, performance and disease-risk headlines.

What to watch for

Common ways headlines can go too far

  • Sleep-tracker data treated as medical evidence
  • Supplement claims based on indirect outcomes
  • Associations with disease framed as causation

Sleep and recovery stories often overstate tracker data, supplement findings or associations with dementia, weight, mood, performance and long-term disease risk.

Common hype patterns

  • Sleep-tracker metrics treated as medical-grade evidence.
  • Supplement or recovery claims based on short-term or indirect outcomes.
  • Associations with disease risk framed as causation.
  • Performance claims presented without clinically meaningful endpoints.

Questions to ask before trusting the headline

  • Was the claim tested in people, or only in cells, animals or models?
  • Is the outcome something patients notice, or only a surrogate marker?
  • Does the headline distinguish association from causation?
  • Are absolute risks, comparators and uncertainty shown clearly?
  • Would the finding change real-world behaviour, or is it mainly hypothesis-generating?

How deHype.io reads this topic

deHype.io separates the public claim from the underlying evidence. The aim is not to dismiss early science, but to show whether the headline has kept the finding in proportion.
