Endothermic reactions are present in cold compresses because they absorb heat from their surroundings, causing a decrease in temperature. When a cold compress is activated, the endothermic reaction absorbs heat from the surrounding area, which in turn lowers the temperature of the compress. This decrease in temperature helps to reduce swelling and inflammation in the affected area, providing relief to the person using the cold compress. Therefore, the endothermic reaction is essential for the cold compress to effectively provide a cooling sensation. **
