Back injuries are common due to campers carrying heavy objects, going through raged terrain and exposure to risks of falling. Dynarex 4518 instant cold pack with urea is a solution to this sharp back pains. It can help calm this problem without the normal side effects.
Dyanarex 4518 instant cold pack measures 5 inches by 9 inches. This area allows it to cover a large surface when applied to the back. It relieves pain in two processes; cold temperatures and application of pressure to the injured tissues. Dynaex 4518 instant cold pack allows the user to squeeze it. One squeeze activates cold temperatures. The cold pack’s cold temperatures lowers the back injured tissues reducing their metabolic rate. Ten minutes of exposure leads to a body’s defense cycle called the hunter’s response. The response initiates blood vessel constriction reducing blood flow to the region and dilation, for tissue nourishment. It makes it easy for the tissue to survive the period after the injury.
The second mechanism is compression; the pack is then applied to the injured area applying pressure. This pressure effects recovery from injury by hindering fluid loss from vessels in the injured area. It makes the area less prone to inflammation. Its flexibility and presence of a covering allows the cold pack to endure more pressure which increases the rate at which it relieves back pains.
