London, June 2026. Cooling strategies have moved from niche sports science to mainstream football conversation, as heat, hydration, player welfare and short breaks become visible parts of World Cup preparation.
FIFA has confirmed that every World Cup match will include three-minute hydration breaks midway through each half, regardless of weather conditions. That creates a repeated player welfare moment in every game, with teams expected to use short stoppages to manage hydration, heat and recovery routines.
YUYU products have now been purchased by a number of national teams preparing for this summer's FIFA World Cup, including England, France, Argentina, Germany, Portugal, Spain, Turkey, Norway, Czechia and Belgium. YUYU products have already been visible with England, France and Norway during World Cup cooling-break coverage and training.
What viewers may see on screen
During hydration breaks, viewers may see players using long, flexible cooling bottles around the shoulders, neck, wrists, palms, face or legs. These are reusable, water-based YUYU ICE Recovery bottles, which can be chilled or frozen and used during short recovery windows.
Cooling kit fit for the breaks that now matter
YUYU ICE Recovery is a 90cm-long wearable cooling system built around YUYU's patented and patent-pending chamber technology. It can be frozen, chilled or filled with cold water.
The YUYU ICE Recovery product is available from www.yuyubottle.com, priced at £29.50.
Used across elite sport environments from Formula 1 paddocks to the Paris 2024 Olympics, where Team GB was among the teams using YUYUs, the product is also finding a wider audience among consumers looking for practical recovery support and a simple way to stay cool in warmer weather.
YUYU is also supplying tournament-branded products to the Lawn Tennis Association for this year's HSBC Championships at The Queen's Club, marking the brand's first formal tennis tournament supply relationship and bringing the same short-window cooling concept into professional tennis.
The long, chambered design can sit around the neck and shoulders, across the wrists or palms, against the face, or across the legs. It is made for short recovery windows where players and staff need practical cooling that is quick to use and easy to manage.
It is simple to operate in real sport environments: fill, freeze or chill, wear, wipe clean and reuse. No batteries. No plugs. No gels.
Sports science
YUYU's long, water-chambered design uses a basic principle of thermodynamics.
The science is based on latent heat of fusion: the energy ice absorbs as it melts. YUYU uses that effect inside long, flexible water chambers, helping draw heat away through contact across several key areas at once.
The product is designed for multi-touch cooling, allowing players to move the bottle quickly between the neck, shoulders, wrists, palms, face and legs during short breaks.
"The question is no longer whether players need cooling, but how quickly and practically teams can deliver it." - Richard Yu, Founder and CEO of YUYU Designs Ltd
