Thermo-Tec's Medical Wraps Ice Packs Belong in the Ice Age Anyone who has used an ice pack before can tell you that the ice quickly becomes painfully cold and requires constant adjustments or removal. Excessively cold temperatures can lead to vasoconstriction, frostbite, or soft tissue damage. Cryotherapy Works Best at 46-54° F The United States Sports Medicine Laboratory and surgeons at Alabama Sports Medicine both determined that the optimal temperature for cryotherapy is between 46° F and 54° F. Ice packs are 32° F, which is far below this optimum range and can even cause additional tissue damage. Thermo-Tec's medical wraps use the same basic "phase changing" principle as ice, but are specially formulated to change from a liquid into a snow-like solid at 50° F instead of 32° F. Where Does It Hurt? Thermo-Tec provides a wide variety of medical wraps: ankle, back, elbow, knee, shoulder, wrist, and a generic multipurpose wrap. Long-lasting, Continuous Use Themo-Tec's medical wraps are specially formulated to "hold the cold" longer than ice, so they can last for several hours before needing a recharge. Thermo-Tec's medical wraps are cool, not cold like ice, they don't require constant adjustment in order to avoid frostbite or other cold-related injuries. And since Thermo-Tec's medical wraps can be strapped on, you can enjoy the benefits of cryotherapy while at work, home, or even out shopping. Limitless, Fast Recharging. Thermo-Tec's medical wraps can be recharged and ready to use when you need them. Simply place the medical wrap in a freezer, ice bath, or refridgerator. Wait 15-30 minutes, then the medical wraps are fully charged and ready for hours of use. Because Thermo-Tec's medical wraps freeze and liquify just like ice, they can be re-used indefinitely. This makes Thermo-Tec's medical wraps an excellent long-term investment for athletes, athletic teams, hospitals, physical therapy patients, and gyms.
