Half-time in football refers to the break that occurs in the middle of a match, typically after 45 minutes of play. It allows the players to rest, rehydrate, and receive any necessary instructions or tactical changes from their coaches. During half-time, the teams leave the field and usually go to their respective locker rooms. It is also an opportunity for spectators to grab refreshments or use the facilities. The duration of half-time is typically around 15 minutes, but it can vary depending on the competition or tournament rules.
