Can cold showers increase speed?


Taking cold showers before aerobic activities like running can enhance performance by increasing the body's capacity to absorb excess heat. This results in slower heat build-up, allowing for either increased speed or greater endurance. Specifically, a cool shower before a long run can delay the point at which you start to sweat and overheat, potentially leading to improved performance in terms of speed 1.
