Modest Weekend Lie‑Ins Linked to Lower Hypertension Risk, Study Finds

A Korea University analysis presented at the European Society of Cardiology shows a small weekend sleep boost may lower blood pressure risk pending peer review.

Overview

  • The Korea University team presented the analysis of roughly 40,000–41,000 South Korean adults at the European Society of Cardiology annual congress in Munich on Sunday.
  • Researchers measured weekend 'catch‑up' sleep as the extra hours people slept on weekends versus weekdays and found any weekend sleep boost was associated with about a 6 percent lower odds of high blood pressure.
  • The study identified a dose‑response 'sweet spot' of about 1 hour 27 minutes extra sleep, linked to roughly a 9 percent lower likelihood of hypertension compared with no catch‑up sleep.
  • Physically inactive participants showed a slightly larger benefit (about a 6.9 percent reduction), but the analysis also found that excessive weekend catch‑ups of more than four hours were linked to higher hypertension risk.
  • The results are observational, have not been peer‑reviewed or published, and researchers say further analysis and replication are needed before changing public‑health guidance on sleep timing.
