Early Bedtimes Linked to Increased Physical Activity, Study Finds
A recent study conducted by researchers at Monash University in Australia has revealed a fascinating connection between bedtime habits and physical activity levels. While the study does not definitively prove causation, it suggests a significant correlation between going to bed early and engaging in more exercise the following day.
The study analyzed data from wearables worn by nearly 20,000 individuals over the course of a year, totaling almost six million data points. The findings indicate that individuals who went to bed earlier tended to engage in more moderate-to-vigorous exercise the next day compared to those with later bedtimes.
According to psychologist Josh Leota from Monash University, the implications of these insights are significant for public health. Rather than promoting sleep and physical activity separately, health campaigns could focus on encouraging earlier bedtimes to naturally foster more active lifestyles.
Interestingly, individuals who went to bed earlier than usual but maintained the same amount of sleep they typically get were more likely to achieve their personal bests in terms of activity levels the next day. This suggests that adjusting bedtime habits could have a positive impact on overall physical activity.
Factors such as age, body mass index, and whether it was a weekday or weekend were controlled for in the study. The researchers also observed a similar but less pronounced relationship in a separate dataset from a more diverse group of individuals, reinforcing the initial findings.
While the study highlights the connection between bedtime and exercise, it is essential to consider other variables that may influence these habits, such as individual chronotypes (e.g., being a ‘night owl’). Further research is needed to fully understand the complex relationship between sleep and physical activity.
Overall, the study underscores the importance of both sleep and exercise in maintaining a healthy lifestyle. By making small adjustments to bedtime routines, individuals may be able to increase their physical activity levels and improve their overall well-being.
Psychologist Elise Facer-Childs from Monash University emphasizes the significance of the findings, noting that getting to bed earlier while maintaining consistent sleep duration could lead to a boost in physical activity the following day.
The research findings have been published in PNAS and provide valuable insights into the interconnected nature of sleep and exercise.
