Just 10 Minutes of Daily Exercise Could Unlock Deeper Sleep, New Research Finds

New research from the University of Texas at Austin suggests people who are physically active more frequently tend to spend more time in deep, restorative sleep.

The findings, published in the Journal of Physical Activity & Health, in October 2026, add to the understanding of the relationship between everyday movement and sleep, raising questions about whether the frequency of exercise deserves more attention.¹

What did the researchers find?

The study examined activity and sleep data collected over several months from university students wearing Fitbit devices. Rather than focusing solely on the total amount of exercise participants completed, the researchers investigated whether the number of days they were active was associated with their sleep patterns.

They found that participants who exercised more frequently tended to spend more time in non-rapid eye movement (non-REM) sleep, which includes the deeper stages of sleep. These stages support physical recovery and brain functions such as memory and emotional regulation.

Among the young adults studied, as little as 10 minutes of moderate-to-vigorous physical activity per day was associated with better sleep. The researchers also observed associations between lighter movement, including walking and taking breaks from sitting, and healthier sleep patterns.

The relationship appeared to extend into the following day, too. Participants who experienced more non-REM sleep tended to report better mood and energy levels, while those who exercised more regularly also tended to experience less stress.¹

Why is deep sleep important?

Sleep is an active biological process that supports the brain and body.

During deep sleep, the body carries out processes involved in physical restoration, while sleep more broadly supports memory, learning and emotional wellbeing.

Previous research has linked physical activity with improved sleep, however, many earlier studies were conducted in controlled laboratory settings and examined relatively short periods, sometimes measuring the effects of exercise over a single night.

By collecting data from participants going about their everyday lives, the University of Texas at Austin researchers aimed to understand how activity frequency and sleep were related over a longer period.

Their findings suggest that how regularly people move could be an important factor in this relationship, alongside the total amount of physical activity they complete.

Does this mean daily exercise improves sleep?

Not necessarily. The study was observational, meaning the researchers identified associations between activity and sleep rather than testing whether changing exercise habits directly improved sleep.¹

The findings therefore cannot establish that exercising for 10 minutes each day will cause someone to sleep more deeply. Nor do they confirm that spreading exercise across the week is better for sleep than completing the same total amount over fewer days.¹

The study also focused on university students, so further research is needed to establish whether similar patterns are seen in older adults and more diverse populations.¹

The research team plans to investigate these relationships in a larger, more diverse group as part of its ongoing work.

For now, the findings offer further evidence of a relationship between physical activity and sleep, while highlighting the need to understand more about how the frequency of movement may influence sleep patterns.
