How Palm Cooling Works
Stanford University researchers identified that mammals regulate body temperature through special blood vessels (AVAs) close to the surface of the skin. In humans these AVAs are most concentrated in the palms of the hands, the soles of the feet and the non-hairy parts of the face.
By utilising these special blood vessels in the palms of the hand – the body’s radiator – the CoreTx Palm Cooling Device cools the blood enabling the body to easily moderate core temperature.
At Stanford they had developed the CoreControl Stanford Glove into which a hand was inserted with the palm placed on a cool pad that had cold liquid circulating through it. At the same time a slight negative pressure was applied to encourage additional blood to flow through the hand. The results were encouraging but the limitation of cooling by conduction meant that longer sessions were required – typically 3 to 5 minutes – to achieve a cooling effect.
In contrast, the patented CoreTx device cools the palm by a combination of conduction and convection enabling sessions to be reduced to as little as 45 to 60 seconds.
Researchers at the University of New Mexico compared the effectiveness of the Stanford glove with and without the use of negative pressure. They concluded there was no significant difference between cooling with vacuum and cooling without vacuum. In fact, cooling without vacuum produced slightly better cooling effect.
