Normal skin indentations usually recover on their own in 30-40 minutes. The body often maintains a position while sleeping, which makes the soft tissues red with pressure and produces indentations. This is a normal protective reaction of the body, and the skin usually returns to its normal form 30-40 minutes after the pressure is removed. However, if the skin of the compressed part does not recover after the lifting of the compression, is a continuous red state, it means that the soft tissue damage, remember not to massage, so as not to aggravate the skin damage, resulting in the indentation more difficult to recover. In daily life, sleeping on air mattresses and sponge cushions can effectively reduce indentation, and for patients with difficulty in turning over, they need to turn over regularly every 2 hours to relieve pressure on various parts of the body. In addition, patients can increase protein food in their diet, which can effectively promote the recovery of indentation.
