- PALM COOLING
The Science-Backed Cooling Technology Powering Elite Sport
How Does Palm Cooling Work?
The Science of AVAs
• The palms of the hands
• The soles of the feet
• The non-hairy areas of the face
These regions act like the body’s natural radiators. As body temperature rises during exercise, blood flow increases through these areas to help dissipate heat. Palm cooling works by applying controlled cooling directly to the palms, allowing the blood to cool rapidly before circulating back through the body.
Two Ways Palm Cooling Improves Performance
2. Neural Activation.
The second mechanism is neural. As more motor units are activated for longer, more muscle fibres are stimulated to contract — enabling athletes to sustain greater effort before fatigue sets in.
Unlike traditional recovery methods such as ice baths, palm cooling can be applied quickly during short rest periods without interrupting training or competition — making it one of the most practical recovery tools available to modern athletes.
Why Heat Management Matters in Sport
During exercise, working muscles generate heat. As muscle and core temperature rise, the body responds by protecting itself — and performance suffers as a result:
• Fatigue increases
• Physical output declines
• Decision-making can deteriorate
• Recovery slows
• Overall work capacity reduces
This is exactly why heat management has become such a critical focus for elite teams, particularly as major tournaments are increasingly played in hot climates. Palm cooling helps delay this natural protective response, allowing athletes to maintain higher performance levels for longer — even under extreme heat stress.

What is palm cooling?
Palm cooling is a recovery and performance technique that cools the palms of the hands to help regulate body temperature, delay fatigue and support faster recovery during exercise.
How does palm cooling reduce fatigue?
It works through two mechanisms: cooling the blood as it passes through specialised vessels (AVAs) in the palms, and stimulating the neural system to activate more motor units for longer, allowing greater effort before fatigue sets in.
How long do you need to use a palm cooling device?
Typical sessions range from 45–60 seconds for rapid cooling, to 60–90 seconds between sets or intervals, with longer sessions used during intense heat exposure or recovery periods.
What is the CoreTx GO?
The CoreTx GO is CET’s portable palm cooling device, designed for sport, performance and recovery applications, using conduction and convection cooling to deliver rapid results.
Is palm cooling the same as an ice bath?
No. Ice baths provide full-body cold water immersion, typically used for post-exercise recovery. Palm cooling is a targeted technique that cools the hands during short breaks in activity, helping to manage fatigue and body temperature without interrupting training or competition.
Who is palm cooling suitable for?
Palm cooling is used by elite athletes, team sports, strength and conditioning athletes, endurance athletes, military and emergency services personnel, and general fitness users — anyone looking to train harder, recover faster and manage heat stress more effectively.
CoreTx GO: CET’s Palm Cooling Device
The CoreTx GO is CET’s portable palm cooling device, developed specifically for sport, performance and recovery applications. Using a combination of conduction and convection cooling technology, the CoreTx GO delivers rapid, targeted cooling to the palms in sessions as short as 45 to 90 seconds.

Who Can Benefit From Palm Cooling?
Why England Players Are Turning to Palm Cooling for the World Cup
With major tournaments increasingly being played in extreme heat, managing core body temperature has become a critical priority for elite football. As reports emerge that England’s squad is set to use palm cooling at the 2026 World Cup, the technology is firmly moving from the research lab into the heart of elite competition.
In hot tournament conditions, players aren’t just battling opponents and physical exertion — they’re battling heat stress and rising core temperature, both of which accelerate fatigue and affect decision-making, recovery and repeat-sprint performance. Palm cooling offers a fast, practical way to help players cool down during breaks in play, half time, substitutions, or immediately after intense phases of a match.
As global sport continues moving into hotter climates, targeted cooling strategies — and devices like the CoreTx GO — are set to become an essential part of performance preparation at every level, from international football down to grassroots clubs and gyms.
