Ten minutes of movement, most days

The claim. Among a group of college students, moving on more days of the week was associated with more time in the deep, restorative stages of sleep — and even about ten minutes of moderate-to-vigorous activity on a given day lined up with a measurable difference.

The study. Corral and colleagues at UT Austin followed students who wore Fitbits for several months, comparing how often they moved with the sleep their trackers recorded. Most earlier work looked at total exercise time; this one asked whether frequency mattered. People who were active more often spent more of the night in non-REM deep sleep, and the same people tended to report better mood and more energy the next day. The researchers note the obvious limit: this is observational, so it cannot show that moving causes the change, and the participants were young adults.

One thing to try. A short daily walk, or a few minutes of anything that gets you breathing harder, on most days — if it fits the day you already have.

What this isn't. Not proof that movement causes deeper sleep, and not a remedy for poor sleep. One observational study in young adults.
