Why does Alcaraz keep blowing on his fingers?

Carlos Alcaraz, the Spanish tennis star, is often seen blowing on his fingers during matches for several practical reasons related to tennis conditions and personal habits. One main reason is to dry his hands and improve grip on the racket, as tennis players sweat heavily during intense matches and blowing on fingers helps evaporate sweat and dry hands quickly between points, especially in humid conditions or long rallies, ensuring better racket control. Another reason is to cool his fingers if they feel hot or sweaty from gripping the racket tightly and from friction, as blowing provides a cooling sensation. Some players also blow on their fingers as part of a ritual or routine to stay focused and reset between points, similar to other players' habits like adjusting strings or bouncing balls, helping with concentration and rhythm. In some cases, players blow on fingers after using rosin or grip powder to spread it. Alcaraz himself has not given a specific public explanation for this habit, but commentators note it is common among tennis players for grip management and is part of his on-court routine. So Alcaraz blows on his fingers primarily to dry and cool his hands for better grip and as a focus ritual during matches.
