A recent study conducted by Harvard researchers has revealed that one of the most effective ways to improve morning running performance has little to do with supplements or training methods, but rather with something as simple as going to bed earlier. The findings suggest that people who go to sleep at least one hour before their usual time are able to run longer and with greater energy in the early hours of the day.
Specialists explain that the body’s circadian rhythm plays a crucial role in physical performance. By aligning sleep with natural cycles, athletes and fitness enthusiasts can gain up to 40 additional minutes of activity without feeling the usual morning fatigue. This adjustment not only benefits professional runners, but also anyone who wants to make morning exercise part of their routine.
But why does sleeping early have such an impact on performance?
The answer lies in recovery. During deep sleep, the body repairs muscles, regulates hormones, and replenishes energy reserves. Without that restorative rest, exercise efficiency drops dramatically.
In short, the research highlights something that often goes unnoticed: rest is as important as training. If the goal is to run further, faster, and with more motivation in the morning, the key could be as simple as turning off the lights a little earlier at night.
