A specific optimal time of day exists for performing daily exercise to maximize health benefits
Emerging research indicates that the timing of physical exercise can significantly modulate metabolic and physiological responses due to interactions with circadian rhythms, suggesting optimal times do exist for specific health goals.
The retrieved papers include recent reviews showing that exercise timing affects circadian adaptation, metabolic regulation, and sleep parameters, pointing toward time-dependent physiological benefits.
