The Claim

In middle-aged and older adults, the optimal combination of sleep (7.2–8.0 hours/day), moderate to vigorous physical activity (42–103 minutes/day), and diet quality (DQS 57.5–72.5) is associated with a 64% lower risk of all-cause mortality compared to individuals with the lowest levels of all three behaviors.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

People who sleep just the right amount, exercise moderately to vigorously, and eat well are 64% less likely to die from any cause compared to those who don’t do any of those things well — especially if they’re middle-aged or older.

  1. Study: Minimum and optimal combined variations in sleep, physical activity, and nutrition in relation to all-cause mortality risk

    This study found that people who slept the right amount, exercised moderately, and ate healthy foods had 64% fewer deaths over time than those who did none of those things — exactly what the claim says.
