palm cooling
CryoTherm Palm is a palm cooling device that lowers core body temperature mid-session to help delay fatigue between sets, sprints and plays so you can push harder for longer. Built for athletes who put the highest demands on their body and expect their output to keep up.

Athletes felt 60% cooler and significantly less strain from heat across repeated sprint efforts 1
4.7% better sprint velocity maintained across repeated all-out efforts 1
58% more reps in the final set when fatigue typically sets in 2
28% more total work volume over the entire session 2
CryoTherm Palm delivers dual-sided cooling to your palms, one of the body's most efficient heat exchange points. Cool them, and you cool the blood circulating to the rest of your body. While ice and cold towels lose their chill in minutes, Cryothermal technology maintains science-backed temperatures throughout your session — so every effort feels easier and you can push through more before fatigue sets in.
Real gains come when each effort starts from a reset baseline. Therabody partnered with University of Southern California to validate CryoTherm Palm in football players. When using CryoTherm Palm, athletes performed 58% more reps in their final set² when fatigue typically sets in. Use between sets, sprints, treadmill or bike intervals to reduce thermal strain and perceived effort, so your last effort hits as hard as your first.
Core temperature rises as a match progresses — and with it, speed, power and decision-making decline. Therabody partnered with IMG Academy to put CryoTherm Palm to the test. When using CryoTherm Palm, athletes increased their top speed by 2.45% during repeated all-out efforts¹. Palm cooling during halftime, timeouts and water breaks helps reset the thermal load. That's how your 80th minute feels like your first.
CryoTherm Palm goes wherever you do, from training camps to away games. Its anti-roll design stays secure on the sidelines, and the lightweight, cordless build fits easily into any gym bag. While others depend on frozen packs, ice baths or tangled power cords, CryoTherm Palm is ready the moment you are — between sets, on the pitch and in the locker room.
CryoTherm Palm is trusted by practitioners and sports scientists to help athletes push past fatigue, maintain output and perform at peak when it matters most.
¹Results from a randomized crossover study conducted at IMG Academy in collaboration with University of Florida involving elite male soccer players (n = 22; ages 17–19) performing 2 sets of 6 repeated sprints, with a single 2.5-minute CryoTherm Palm application between sets. Results compare intervention to control conditions and may not reflect outcomes in other training contexts, athlete levels, age groups, or populations. Learn more here.
²Results from a randomized crossover study conducted with University of Southern California involving D1 collegiate athletes (n = 21) performing 4 sets of overhead presses to failure at 85% 1RM, with a single inter-set CryoTherm Palm application between sets. Results compare intervention to control conditions and may not reflect outcomes in other training contexts, athlete levels, or populations. Learn more here.
Palm cooling is a targeted method of regulating body temperature by applying controlled cooling to the palms of the hands. The palms contain specialised blood vessels called arteriovenous anastomoses (AVAs) that allow large volumes of blood to flow close to the surface of the skin. Because of this, the palms are one of the body's most efficient heat exchange points. When you cool the palms, you're effectively cooling circulating blood — which has downstream effects on core temperature, performance, fatigue, and perceived effort.
Ice and gel packs lose temperature quickly, cannot maintain a consistent therapeutic range, and require freezing and setup. If a surface is too cold, it causes vasoconstriction — blood vessels narrow and heat exchange becomes less efficient. CryoThermal Technology reaches therapeutic temperature in seconds and maintains it for the full duration of treatment, with no ice, water, freezing, or external power required. It is portable, cordless, and ready to use anywhere.
CryoThermal Technology delivers scientifically calibrated temperatures that reach and maintain the therapeutic range in seconds. The device is portable and cordless — no ice, water, freezing, or external power required.
Use palm cooling during natural rest periods — between sets while training, at halftime, during timeouts, water breaks, or changes of possession. For strength and hybrid training, use between sets or intervals to maintain strength, power, and movement quality deeper into the session. For intermittent sports (soccer, basketball, football), use during any break to sustain speed, power, and repeat-effort capacity in the later phases of the game. For endurance training, use during structured interval work to reduce thermal strain and sustain pace.
Current research shows as little as 1 to 3 minutes during rest periods can be enough to meaningfully impact thermal strain and performance outcomes. For indoor training and strength & conditioning, use 1-3 minutes between sets or efforts. For outdoor training or game use, 3 minutes is recommended. During halftime or extended breaks, use for as long as possible.
The device is designed for both indoor and outdoor use in hot environments. For indoor use (or outdoor use in temperatures below 23.8°C), the device will cool quickly and perform optimally on the Level 2 cold setting. For outdoor use or in environments above 23.8°C, use the Level 3 setting for optimal temperature performance and allow additional time for the device to cool by turning it on approximately 2 minutes before use.
