To run in winter, dress so that you feel a slight chill during the first 10 minutes. The heat produced by physical exertion will naturally compensate for this initial cold, thus avoiding the overheating associated with clothing that is too warm.

This advice is well-founded in terms of thermal regulation during exercise. When running, our body increases its internal heat production to support movement. The recommendations from the American College of Sports Medicine (ACSM), based on expert consensus, actually advise dressing as if it were approximately 10°C warmer than the actual temperature to anticipate this warming effect. A scientific review published in Sports Medicine (observational study) confirms that the accumulation of sweat due to clothing that is too warm reduces the insulating power of fabrics and impairs comfort in the medium term. While the exact ten-minute duration to warm up depends on individual intensity, the creator's basic logic is scientifically sound for optimizing thermal comfort.
