Sleep duration patterns associated with subsequent mortality and cardiovascular events

Takeaway

  • Low duration of sleep, or unstable sleep patterns over a 4-year period were associated with a higher risk of subsequent mortality or cardiovascular events.

Why this matters

    Short and long sleep durations are known to be associated with increased mortality, but the effect of long-term sleep patterns is unknown. People reporting consistently less than 5 hours’ sleep per night may be at higher risk of subsequent mortality or cardiovascular events.
