The CoreControl™ Cooling Glove was invented and developed by Stanford University Doctors, Dennis Grahn and H. Craig Heller, who have completed extensive research on body cooling, in conjunction with the United States Military Defense Advanced Research Project Agency (DARPA).
CoreControl™ was originally developed on the principles of Mammalian thermoregulation. All mammals have specific regions of the body surface designed for dissipating excess heat from the body core to the environment – ie. a dog’s tongue, or rabbits’ ears.
Blood is pumped to these surfaces when metabolism increases, such as during exercise or heat stress.
In humans, some of these surfaces are found in the palms of the hands. It is through these skin regions that humans dissipate heat through specialized blood vessels called arteriovenous anastomoses.
The CoreControl™ cooling glove enhances heat extraction through these radiator surfaces by amplifying local blood flow using a hand held device that has the combination of carefully controlled temperature settings and a slight vacuum.
The combined application enhances the natural heat exchange of these radiator structures, cooling a person effectively and efficiently to a normal body temperature.
When utilizing the CoreControl™ cooling glove, the skin is not noticeably cooler to touch or feel, however perspiration does decrease and the body temperature is returned to normal. Perceived skin temperature does not directly equate to critical core body temperature. Most temperature sensors are on the skin, not deep within the core body making it difficult to sense the change.
CoreControl™ developer Craig Heller Ph.D. explains ‘while traditional cooling methods make the victim feel cooler on the outside, they are not effective in extracting heat form the body’s core organs, In fact, laboratory testing demonstrates that these methods may make matters worse. When cold is applied to the body’s surface, it can trigger constriction of the skin’s blood vessels which interferes with cooling’.

Other cooling products including misting fans, wet towels, cooling vests, neckties, chill packs or ice water do not work as effectively as CoreControl™ as they attempt to push cold into the body through the skin, fat and muscles, which are very effective insulating materials.
CoreControl™ can accomplish heat extraction more efficiently, safely, and faster than these other technologies alone, working with the body’s natural adaptions.
If humans are subjected to exertion in sweltering conditions performance is affected. As the temperature of the body’s core organs (heart, lungs, liver, kidneys, and brain) rise, fatigue sets in and strength, endurance and cognitive functions deteriorate rapidly. CoreControl™ is able to offer a fast, effective and safe solution to limit this occurring.
The CoreControl™ cooling glove is now being utilized by emergency workers, employers of workers required to operate in a heat stress environment, and of course athletes, who all want to avoid or recover from heat stress.
CoreControl™, the only scientifically proven, non-invasive core body temperature cooling device.
Remove the cooler from the bag by depressing the connectors release button and disconnecting the tubes.
Remove the lid and fill cooler with ice and water to just below the connector inputs. Verify the tubing and bulb are below the water. Very little water is needed for the system once primed, the cooler can be filled to just below the connector inputs with ice, and then add water to the same level
Turn the power of the unit on.
Insert your hand into the hand pod with palm facing toward the umbilical side of the hand pod. Be sure your hand is inside of the perfusion pad with the pad wrapping around the entire hand. Gently rest your hand on the hand pod perfusion pad. The hand support pad creates a bump in the pad to achieve good contact with the hand pod perfusion pad and your palm. Full contact with the palm is necessary for maximum heat transfer.
Pull wrist support and wrist seal over arm. Wrist seal must be in contact with the skin of the arm to seal, remove clothing or wraps between wrist seal and arm. Caution: the wrist seal and hand pod pad can be torn by bulky rings, bracelets, and other sharp objects therefore please remove jewelry/objects from hand and wrist prior to inserting your hand into the hand pod.
Keep hand in hand pod during required cooling. A vacuum will be felt on the hand during the operation of the unit. It is normal for the vacuum pressure to increase and decrease during use
Once desired cooling effect is achieved turn unit off and remove hand from hand pod.
For additional cooling, turn unit back on and insert hand back into hand pod. Note: power of the unit can be left on while your hand is not in the hand pod without causing damage however this will shorten the duration of time the unit can operate between required battery charges.
When the water within the cooler is no longer cold enough to provide sufficient cooling the Yellow LED light will illuminate. Replace the water with iced water.
It is recommended that the unit be powered off if not being used. The Red LED light will illuminate once the battery charge is low.
You need to prime your CoreControl™ unit before you can begin cooling. Priming the system prior to use is necessary to remove the air from the water tubes that guide cooled water to and away from the perfusion pad. Priming is required before the first use and before you use the unit after it has been purged and/or stored.
Clean lukewarm water is needed for priming.
Note: Do not use ice water for priming!
In order to avoid contaminating internal components and preventing mildew growth, all CoreControl™ units must be cleaned periodically. Cleaning and purging your unit is especially important if travel or long-term storage is necessary.
Prior to long-term storage or long distance travel, the CoreControl™ unit should be purged in order to remove the water from the system. Before purging, check all mating connections to insure that they are properly attached.
