Sleep is an essential aspect of our overall well-being. We all crave a good night’s sleep, but sometimes achieving it can be a challenge. Many of us are aware of the benefits of regular exercise on sleep quality. However, the timing and intensity of exercise in relation to bedtime have been points of contention. While it’s generally advised against engaging in intense exercise right before bed, a new study suggests that short bursts of movement in the evening may actually improve sleep quality.
The study conducted by researchers at the University of Otago in New Zealand involved 28 volunteers. These participants were divided into two groups, with one group spending an evening sitting uninterrupted for 4 hours before bed, while the other group engaged in 3 minutes of body-weight exercises every half hour for the same 4-hour period. The exercises included chair squats, calf raises, and standing knee raises with straight leg hip extensions, which were designed to be simple and doable at home without any equipment. Participants wore wrist-watch accelerometers to track their movement, and various factors such as food intake and bathroom breaks were controlled for.
On average, participants who incorporated short bursts of exercise into their evenings slept roughly 30 minutes longer compared to those who remained sedentary. Interestingly, the study found that while the evening exercise did not affect the number of times people woke up during the night, it did not compromise the quality of their sleep either. These findings go against the current recommendations that advise against engaging in vigorous exercise close to bedtime.
While the results of this study are promising, it is important to note that this was a small study conducted mostly with young women. Therefore, further research with larger and more diverse groups is needed to generalize the findings to a broader population. However, the researchers are optimistic that simple exercises like the ones used in the study could be an easy and effective way for people to improve their sleep quality without disrupting their bedtime routine. According to University of Otago sports scientist and nutrition researcher Meredith Peddie, activities such as walking around the house, marching on the spot, or dancing in the living room could potentially yield similar benefits.
The impact of exercise on sleep quality is a topic of great interest and relevance. While the traditional advice has been to avoid intense exercise before bedtime, this new study suggests that incorporating short bouts of movement in the evening may actually enhance sleep duration without compromising sleep quality. Further research is needed to confirm these findings and explore the potential benefits of light evening exercise on a larger scale. In the meantime, individuals looking to improve their sleep quality may consider integrating simple exercises into their evening routine as a possible solution.
