Sleep
What it is
- Your sleep quality, duration, consistency, and the habits that shape how well you rest and recover each night.
Why it matters
- Adults who consistently sleep fewer than seven hours face a 13% higher risk of dying from any cause, and even one night of poor sleep impairs reaction time, memory, and mood to a degree comparable to mild alcohol intoxication.
