10 minutes of daily exercise may improve sleep quality

Nour Nour El-Din: You don’t need to spend long hours in the gym to improve your sleep. A recent American study suggests that just ten minutes of physical activity per day may be associated with better sleep quality and increased time spent in deep sleep. Researchers from the University of Texas at Austin conducted a study published in the Journal of Physical Activity and Health, aiming to explore the relationship between regular physical activity and sleep quality, focusing on daily movement consistency rather than the number of weekly exercise hours.

Consistency Makes the Difference: The researchers relied on data from university students who wore smart devices to track their physical activity and sleep patterns over several months. The results showed that individuals who engaged in more consistent physical activity spent more time in deep sleep stages compared to those with less consistent movement. Notably, just ten minutes of moderate-to-vigorous physical activity daily was linked to better sleep quality indicators, suggesting that short sessions may also be beneficial. This activity could include brisk walking, cycling, or taking the stairs, provided it leads to a moderate increase in breathing rate and heart rate.

Why Does Physical Activity Help You Sleep? The body goes through different sleep stages at night, including deep sleep, which plays a crucial role in energy restoration, tissue repair, and supporting memory and immune system functions. Exercise may help regulate the body’s biological clock, reduce stress, and improve the balance between activity and rest. Researchers also noted that participants who were more consistent with their movement tended to feel more energetic and less stressed the following day. These findings suggest a possible bidirectional relationship between physical activity, sleep, and mood: moving during the day may help you sleep better, while good sleep contributes to enhanced activity and psychological well-being.

Is Ten Minutes Really Enough? Despite the encouraging results, the study does not mean that ten minutes of exercise guarantees deep sleep or cures insomnia. The research was observational, meaning it identified an association between physical activity and sleep quality without proving direct causation. Additionally, the study included young university students, so its findings cannot be generalized to all age groups. Furthermore, fitness trackers provide estimates of sleep stages and lack the precision of specialized tests conducted in sleep laboratories. General health recommendations still advise at least 150 minutes of moderate physical activity per week, along with muscle-strengthening exercises.
