How Manchester United and other clubs use 'smart urinals' for hydration tracking
Professional football teams, including Manchester United, have introduced 'smart urinals' in their men's facilities to track player hydration levels instantly. Before using the facility, players choose their personal profile via a screen mounted above the unit. The system then evaluates the urine for various metrics, such as electrolyte levels, colour, volume, frequency, and specific gravity, providing each player with a personal 'hydration score'.
