They switch sides at halftime to keep the match fair. That way, both teams deal with the same conditions, like sun glare, wind, and any small slope or unevenness in the field.

Why it happens

  • Fairness: Neither team should get the better end of weather or field conditions for the whole game.
  • Game balance: One side of a pitch can feel different because of sunlight, wind, or turf quality.
  • Tradition and rules: Switching ends at halftime became a standard part of the sport and stuck over time.

Simple example

If one team spent the whole first half shooting into the sun, they could be at a disadvantage. Switching sides means that disadvantage gets shared instead of affecting only one team.

Extra note

Teams also use halftime to rest, reset tactics, and adjust to what happened in the first half.
