Environmental heat stress is the result of ambient temperature, radiation, and relative humidity. During football practice on synthetic surfaces and no roof, solar radiation causes an important temperature increase of the playing surface. This technical note explains how heat stress is calculated according to the WBGT index (which does not consider playing surface temperature), and quantifies the increase in a synthetic surface compared to natural grass on the same site. Football practice should be avoided during those hours with the highest solar radiation and temperature on this type of surface. El estrés por calor ambiental ocurre por una combinación de la temperatura, la radiación y la humedad relativa del ambiente. Cuando se practica el fútbol en canchas sintéticas no techadas, la radiación solar produce un aumento importante de la temperatura de la superficie de juego. En esta nota técnica se explica cómo se calcula el estrés por calor según el índice WBGT (el cual no contempla la temperatura de la superficie de juego), y se documenta la magnitud del aumento en la temperatura de una superficie sintética, comparada con zacate natural en el mismo lugar. Se recomienda evitar la práctica del fútbol en las horas más calientes y con mayor radiación solar del día en este tipo de superficies.
