Cardiologist’s Instagram Advice: Take a Warm Shower Before Bed to Sleep Better

His Instagram post cites a 2019 review linking a warm shower 1–2 hours before bed to faster sleep onset with higher sleep quality.

Overview

  • Aurelio Rojas tells his 713,000-plus Instagram followers that evening showers improve sleep metrics, referencing peer‑reviewed evidence rather than new research.
  • Coverage cites the 2019 Sleep Medicine Reviews meta‑analysis of 17 studies, which supports warm water of roughly 40–42.5°C taken 1–2 hours before bedtime.
  • Reports relay a stated 36% reduction in time to fall asleep, alongside gains in sleep efficiency and total duration, with study methods varying across trials.
  • Rojas explains the proposed mechanism as skin vasodilation with heat loss, a drop in core temperature and melatonin signaling that ease sleep onset.
  • Media also relayed broader wellness claims and separate assertions about kissing and cholesterol with limited support, while one piece offered a hygiene‑focused case for morning showers and regular weekly bedding washes.
