Every claim below was made in this piece, quoted word for word and numbered in the order the piece makes them, so you can read it there rather than take our word for it. The sentence above each quote is our reading of the claim, not their wording. Each quote was checked against a stored copy of the page at build time; where the two differ, the quote is the fact.

  1. Given what we know about sleep loss, that conclusion makes sense—but being reasonable isn’t the same thing as being proven.
  2. Sleep is a lever on body composition, metabolism, and mood, and deprivation pulls in the wrong direction across nearly every axis at once.
  3. Population-level studies will keep struggling to prove that short sleep shortens life, because they are structurally unable to separate cause from symptom—and the genetic tools meant to overcome this limitation inherit a different fatal flaw.
  4. So a rough night here and there is nothing to agonize over.
