The French Open has once again highlighted one of the biggest challenges in elite tennis: heat. World No.1 Jannik Sinner’s second-round defeat highlights the impact of heat stress after he claims his reason for defeat was due to muscle cramps and dizziness experienced on court.

The encouraging news is that heat tolerance can be trained.
