New research from The University of Texas at Austin has revealed that increasing the frequency of exercise — ideally engaging in physical activity every day — can significantly enhance sleep quality. This improvement is particularly noted in deep, restorative sleep, which is essential for better mood and mental health.
Published in the Journal of Physical Activity & Health, the study analyzed data obtained from UT students who wore Fitbits over several months. Unlike previous studies that primarily focused on the overall amount of exercise time, this research emphasizes the importance of how often individuals engage in physical activity.
Benjamin Baird, a research assistant professor of psychology in the College of Liberal Arts, led the study and explained the researchers’ objective: “We wanted to know whether it matters if someone spreads out their exercise over the week versus doing it all at once, like a ‘weekend warrior.’” His findings indicate that for sleep health, exercise frequency is indeed crucial.
Chris Corral, who co-led the study and has recently earned a master’s degree in health behavior and health education from UT, noted the research builds upon earlier findings that linked regular exercise with improvements in non-REM, or deep sleep. This type of deep sleep, particularly in the early part of the night, plays a crucial role in both physical and mental recovery.
The study participants who engaged in more frequent exercise reported experiencing more restorative sleep. Baird highlighted this benefit, stating, “That’s exactly what you want.” Remarkably, even just 10 minutes of moderate to vigorous activity each day was sufficient to show a notable difference among the young adults studied.
Moderate to vigorous activity was defined in the study as exercise that raises breathing rates but still allows for conversation, roughly equating to a 6 on a 1-to-10 effort scale. Despite this, the researchers found that even lighter activities, such as regular walking or standing breaks, contributed positively to better sleep patterns as well as improved mood the following day.
The study revealed additional benefits for those who exercised more frequently, such as feeling more energized and less stressed. Baird mentioned, “We saw that more non-REM sleep was tied to better next-day mood and energy.”
Historically, scientific studies and personal experiences have affirmed the link between regular exercise, improved sleep, and enhanced overall well-being; however, much of the existing research has primarily been conducted in lab settings, often assessing effects after just one night of activity.
This study distinguishes itself through the innovative use of wearable technology. By continuously monitoring participants’ activity and sleep patterns over several months, researchers gained comprehensive insights into how daily habits influence sleep and mood over time.
These findings are part of the Whole Communities—Whole Health research initiative, which adopts an interdisciplinary, community-engaged approach to studying health and well-being. The research team is now preparing to examine whether these findings hold in larger populations as part of the Whole Communities—Whole Health five-year cohort study.
Corral pointed out that while current guidelines from the Centers for Disease Control and Prevention and the World Health Organization suggest individuals should accumulate 150 minutes of exercise per week, they do not clarify how to distribute that time effectively. “Our results suggest that daily movement may be better for sleep than doing it all on the weekend,” he noted.
If further research substantiates these results across broader and more diverse populations, it could potentially lead to significant updates in public health recommendations.
Baird emphasized, “Current guidelines don’t reflect the importance of frequency for sleep health.” This research presents valuable data that prompts consideration of whether existing guidelines should be revised.
Beyond the implications for sleep, the research speaks to wider health concerns. Corral elaborated, “Sleep is when your brain stores memories, clears waste, and resets. Better sleep means better brain health and potentially lower risks of chronic disease and depression.”
In summary, the takeaway from this study is clear: engaging in daily physical activity, even in small amounts, can lead to substantial improvements in sleep quality. Corral concluded, “You don’t need to run marathons. Just moving a little each day helps. Light activity counts too. Doing something is better than doing nothing.”
