Four Pillars of Good Sleep

  • Good sleep has four components: quantity, quality, regularity, and timing (QQRT).
  • Regularity, or consistent sleep and wake times, may be more impactful than quantity.
ADVICE

Prepare for Sleep

  • Set a "go-to-bed" alarm one hour before your bedtime and start your wind-down routine.
  • Dim the lights and avoid screen time to boost melatonin production and relaxation.
ADVICE

Track Your Sleep

  • Track your sleep for at least six weeks to understand your individual sleep patterns.
  • Many underestimate their sleep quality until they see tracked data.
