Generally, warm air conditioning is allowed in the early stage of recovery and you can decide whether to have cold air conditioning depending on the weather conditions. In the early recovery period of fracture, there is bleeding in the vascular tissues around the fracture site, and hematoma may be formed resulting in impaired blood circulation. At this time, blowing appropriate warm air conditioning can promote blood circulation and speed up recovery. If the weather is hot, the patient can blow cold air to avoid sweating at the fracture site, which is not conducive to wound healing. At the later stage of the recovery period, the fracture end is gradually healing completely, and the related bleeding place is gradually healing, you can blow cold air appropriately. If you are in the recovery period of fracture, you should pay attention to nutrition and make sure that your diet is reasonable and nutritious. You can eat some high-protein and high-calcium foods to promote the generation of bone scabs and ensure adequate nutrition for fracture healing. If the fracture occurs, you should go to the hospital in time for relevant examinations to determine the fracture site and carry out relevant treatment under the guidance of the doctor.
