University of Texas study links frequent short exercise to better sleep

Researchers at the University of Texas at Austin have found that the frequency of daily physical activity is closely linked to improved sleep quality. According to a study published in the Journal of Physical Activity and Health, engaging in even short bursts of moderate to vigorous activity can lead to more restorative sleep.

The study, which monitored young adults using wearable fitness trackers over several months, indicated that having more days with at least 10 minutes of moderate to vigorous activity was associated with changes in sleep stages during the first three hours of the night. Specifically, active participants showed a higher proportion of non-rapid eye movement (non-REM) sleep early in the night.

Beyond intense exercise, the research also noted that increased light activity was linked to higher reported energy levels the following morning. The findings suggest that spreading activity across more days of the week may be more beneficial for sleep patterns than concentrating exercise into fewer sessions.
