Cells rely on a natural cleanup system to prevent damaged materials from accumulating inside them. Known as autophagy, this process collects defective proteins and other cellular waste, packages them into specialized compartments, and breaks them down into basic molecular components that can be reused. This recycling system helps protect cells from damage. Scientists have long considered declining autophagy a hallmark of aging, and problems with the process have been linked to numerous diseases, including cancer, cardiovascular disease, diabetes, and neurodegenerative disorders.

What if getting better sleep depends not just on how much you exercise, but how often you move? Research from The University of Texas at Austin suggests that being physically active every day, even for short periods, may help people spend more time in the deep, restorative stages of sleep that support recovery, mood, and mental health. The findings suggest that consistency could be an important but often overlooked part of the relationship between exercise and sleep. Rather than saving all their workouts for the weekend, people may benefit from making movement a regular part of their daily routines.
