Heat Guards, a unique product from Practical Design, are carefully designed and produced to relieve heat and provide a natural cooling feeling effect. A Heat Guard cooling tie only needs to be soaked in water for about 20 minutes - the tie contains polymer crystals which absorb water and slowly release it into the fabric providing natural cooling through evaporation. No refrigeration is necessary to produce this effect. The crystals, which expand to more than 400 times their original weight, store enough water to continually keep you cool for a full day.
Heat Guard ties are reusable and can be re-soaked daily. They are available in a variety of cute designs, some of which are shown in the gallery below.
We recommend the Heat Guard ties to provide relief to people undergoing chemotherapy and radiation, hormonal or menopausal women who experience hot flashes, migraine sufferers, and those who frequently work outside or in hot areas like kitchen or laundry staff. When worn around the neck, the tie cools the blood in your carotid arteries flowing to and from your brain - literally, it prevents your brain from overheating. These key arteries are connected to the rest of your body and the cooled blood carries on to cool the rest of your body.
