England are preparing to deploy palm-cooling devices during the World Cup in the United States, as the squad braces for punishing heat and humidity throughout the tournament.

Studies indicate that at least a third of World Cup fixtures will be played in temperatures exceeding 26C. The conditions are already making themselves felt — on Tuesday, the mercury climbed to 32C during England's opening training session in West Palm Beach, Florida.

How palm cooling works

Palm-cooling technology works by lowering core body temperature through the hands, a method that research suggests can significantly aid in-game recovery and lift overall performance. The approach has gained traction across professional sport, with Manchester United among the clubs already known to use it.

England's coaching staff plan to deploy the devices both in training and during the scheduled water breaks that will punctuate World Cup matches.

Henderson backs the science

Brentford midfielder Jordan Henderson spoke about the squad's approach to adjusting to the Florida heat, describing the opening week as an opportunity to "build capacity to the conditions." He noted that the upcoming friendly fixtures would further sharpen that preparation.

Henderson also credited the backroom staff, praising the "team behind the team" for the "top level research" carried out on recovery and cooling strategies.

"Hopefully that can give us a little edge when we get into the tournament," Henderson said.
