A new study suggests that engaging in brief bursts of light intensity exercise before bed can actually improve sleep duration, contrary to traditional advice. In the study, participants who did three-minute activity breaks every half hour before bedtime slept for an additional 27 minutes on average compared to those who sat uninterrupted. The exercises, such as chair squats and calf raises, were chosen for their simplicity and ability to be done at home without equipment. While the study had limitations, including a small sample size and a controlled setting, it provides insight into the benefits of incorporating short bouts of physical activity into an evening routine for better sleep.
