Broken, wipe off the epidermis together. Only the parts with thick cuticle, such as palm and sole, will seep out between epidermis and subcutaneous tissue due to constant friction during exercise, forming blisters. On the other hand, the subcutaneous tissue of the blister-prone part is often closely attached to the tissue and cannot move with the surface skin when rubbing, so the two parts will crack due to different directions of stress, and the interstitial fluid will quickly enter this crack to form water. External causes: mainly sweating, feet and shoes squeezing each other, making the inside of the shoes moist and the local temperature rising relatively, causing cutin softening and blisters. On the contrary, dry skin has less friction and lower probability of blistering. How to prevent blisters on the soles of feet? Choose a pair of suitable shoes. Blisters on feet are directly related to shoes. If the shoes are too tight, they will squeeze the soles of your feet when surfing the internet and starting. If the shoes are too loose, there will be more opportunities for feet and shoes to rub during exercise. Shoes that are too tight or too loose may cause blisters on the soles of the feet, so it is important to wear a pair of suitable sports shoes during exercise to reduce the chance of foot friction. Badminton shoes require wear-resistant, non-slip and good toughness soles. The joint between the sole and the upper is hard, which can not only support the ankle well, but also reduce the friction of the sole, and it is not easy to sprain the ankle. The sole should be made of raw rubber or beef tendon, with fine and staggered lines, friction resistance and good grip. However, the soles of running shoes are thick and easy to slip on the wooden floor. The soles of badminton shoes should also have the function of shock absorption and buffering, and the heels should be flat to facilitate exertion. Many non-professional shoes have heels and are not suitable for playing badminton. Shoes have strong air permeability, which can keep the inside of shoes dry and the temperature is appropriate, and prevent the epidermis of feet from softening and foaming. Because badminton training and competition take a long time, you have to sweat a lot when you exercise. Therefore, when choosing a shoe size, it should not be too tight or too loose. After wearing them, it is best to leave some space in the length to avoid toe collision when surfing the internet, jumping, stopping and turning. Tie your shoelaces tightly when you wear them. Badminton shoes are best worn when playing. On the one hand, they can prevent shoes from polluting the ground, on the other hand, they can prevent the soles from accumulating dust and slipping. In addition, badminton shoes also have certain requirements for the arch of the foot, and the curvature of the arch should be moderate, and it is not good to bow too flat or too upward; At the same time, the arch of the foot should be hard and have certain supporting force, which can improve the exercise effect. Give your feet a few days to get used to the new badminton shoes, and then put them on to play. During the adaptation period, find out the uncomfortable part and beat it with a hard object at this position to make it soft. Remember, you must not wear new shoes that have not been "run-in" to compete and train. Wear thick sports socks with strong sweat absorption. Socks can keep feet dry and reduce the friction between feet and shoes. Also avoid wearing old socks that have been washed too many times and are hard in texture, because they are hard and not easy to wear flat, so they are easy to rub with the soles of the feet to produce blisters. If your feet often get blisters, you can consider sticking a film on the parts that often get blisters in advance, and fixing them with muscle stickers outside, which will effectively prevent local friction from getting blisters. Soak your feet with warm water before going to bed to promote blood circulation. If the calluses are found to be too hard, they should be thinned and leveled in time, especially the partially treated parts after blisters. They must be flat and have no hard edges. After soaking feet, you can also massage the soles of your feet and use some types of rubbing methods to make the keratinized layer not too hard. When not wearing shoes, put them in a well-ventilated place and keep them dry. If you find any discomfort or pain in your feet during exercise, you should stop and have a check-up. If there is no blister, put a membrane on the painful part and fix it with a muscle patch outside, and deal with it in time. Prolonging the exercise time step by step can make the skin slowly adapt to the friction generated by the activity, and have enough time to form a protective callus, which can prevent blisters on the soles of the feet. It is best to prepare two pairs of sports shoes that fit your feet and replace them with each other. Wearing different shoes on your feet, the contact position and pressure are always different, which can reduce discomfort and reduce the chance of blisters. Once blisters appear, it is important to relieve the pain, avoid the expansion of blisters and prevent infection. Very small blisters can usually be absorbed by themselves in a few days. Don't break the epidermis of blisters at this time, which will not only aggravate the pain, but also be easy to get infected. During training, the local area can be covered with film, and the lateral area can be fixed with muscle patch. Disinfect in time after training to prevent infection. Slightly larger blisters often have obvious pain, which affects training. At this time, the accumulated water can be discharged to relieve the pressure caused by blisters.
If the blister is large and has been broken to form a wound, it should be bandaged, the blister epidermis should be trimmed neatly, and the sterilized dressing should be affixed, and the dressing should be changed regularly.
After a long time, after the liquid in the blister is slowly sucked dry by itself, the epidermis becomes hard and the surrounding skin becomes soft. Once moving, the edge is easy to bubble again. At this time, it is generally necessary to thin the hard stratum corneum and apply ointment on the surface to make it soft and avoid foaming at the edge.
