The skin is the barrier between the human organism and the external environment, not only plays a protective role, but also is a beauty organ that needs to be taken care of carefully, and many people do the same. However, beauty care can not only focus on the face, a pair of healthy and beautiful hands and feet is also very important. Winter is approaching, the most vulnerable to the outside world may be the hands and feet. We will talk to you today about how to do a good job of winter hand and foot care. First, let’s analyze the characteristics of the skin of the hands and feet. We stretch out our hands and feet to take a closer look, you can find that the skin surface has many small grooves, which are caused by the arrangement of dermal fiber bundles and pulling, while the depth of the grooves on the extensor and flexor surfaces of the hands and feet are not the same. In addition, the thickness of the extensor and flexor surfaces of our hands and feet are not equal. The thickness of the skin varies according to age and location, with the palm of the hand and the sole of the foot being the thickest parts of the skin on the human body. The surface of the skin of the palms and soles of the feet is a thick layer of keratin, which can effectively play a protective role. The stratum corneum is particularly thickened in areas of the body that are subject to frequent friction and pressure to enhance tolerance to mechanical stimuli. However, if the stratum corneum is too thick, it becomes less elastic and can easily lead to cracking. There are many reasons for the thickening of the stratum corneum, besides friction, genetics, occupation, acids, alkalis, organic solvents, fungal infections, etc. are also important factors. The sebaceous glands are widely distributed throughout our skin, and the sebum secreted can moisturize our skin, prevent water loss, maintain skin elasticity and prevent some bacterial and fungal infections. However, the curved surface of the hands and feet, often referred to as the heart of the hands and feet but no sebaceous gland distribution, if these parts of the weekdays do not apply moisturizing cream, but also easy to cause dry hands and feet. Secondly, let’s look at what physiological changes have occurred in the skin of hands and feet in winter. Winter sebaceous gland secretion is reduced, sweat secretion is also reduced, so the sebaceous film formed by the mixture of the two is thinner than in summer, so the skin is drier in winter, coupled with the impact of various other factors, so that the stratum corneum thickens, becomes brittle and hard, elasticity is reduced, when the local activity or pulling force is greater, it can cause the skin of the hands and feet along the skin furrow cracking, cracking. After the cold stimulation of the skin of the hands and feet in winter, the small blood vessels of the skin on the back of the hands and feet contract strongly, causing skin ischemia and hypoxia, cell damage, metabolic disorders, paralytic expansion of blood vessels, plasma exudation, the formation of edema or tissue necrosis that is commonly referred to as frostbite. Frostbite is more likely to occur in humid environments, where heat dissipation from the body surface is accelerated. Knowing these characteristics of hand and foot skin and some characteristic changes in winter, we can take care of it accordingly. For hand and foot health people use skin care products to protect hand and foot skin has a very important role, especially in winter more obvious. Every time you wash your hands and feet immediately after drying, apply moisturizer, dry skin people should use oil-based lipid skin care products. Skin care products need to use the latest products, so as to avoid the expiration of time or deterioration. Pay attention to the need to supplement appropriate nutrition. Winter diet should be diversified, you can eat more cold food such as mutton, dog meat, chili, etc., to promote skin blood circulation and metabolism, so that the skin is lustrous and elastic. Eat more foods rich in vitamin A to prevent dry skin, such as animal liver, carrots, etc. Toenail care is also very important. Pay attention to diligent trimming of finger and toe nails, immediately after cutting nails with a nail file polishing edge can avoid scratching their own skin. Winter skin circulation is poor, if the cut will heal more slowly. Appropriate physical exercise can enhance physical fitness. People prone to frostbite begin to insist on cold water for hand and foot washing before winter, in addition to promoting local skin circulation, eliminating microcirculatory disorders and improving the nutritional state of the skin, while also improving the skin’s ability to adapt to changes in the external environment. Several times a day, rubbing the hands and stretching the joints of the hands for several minutes each time until the local skin is warm, can prevent the occurrence of frostbite. If there are skin diseases on the hands and feet, they need to be treated first. The most common skin disease of the hands and feet is chapped hands and feet. The hand and foot crack refers to the dry and cracked skin of the hands and feet caused by a variety of reasons, can be an independent disease, but also some skin diseases accompanying symptoms. It is common in autumn and winter, especially in the cold season to engage in open-air work and exposure to gasoline, detergents, cement or lime and other chemicals are prone to develop. Mostly on the fingertips, palms, toe joint surfaces, heels, and the lateral side of the foot plantar. Chaps on the hands and feet can also be secondary to certain skin diseases, such as palmoplantar keratosis, chronic eczema, contact dermatitis, ringworm, frostbite, etc. If it is simply cracked hands and feet, you can soak in hot water every night until the skin turns white, then trim the softened keratin and apply petroleum jelly ointment. If you feel that the smear is too greasy to contaminate clothing, you can wear gloves and socks overnight. If you’re looking for a new way to get the most out of your home, you’ll be able to get the most out of your home. The actual fact is that you can find a lot of people who are not able to get a good deal on this. The actual fact is that you can find a lot of people who have been in the business for a long time. The patient needs to pay attention not only to the warmth of the hands and feet but also to the warmth of the whole body, clothing and footwear should be loose and tight and kept dry. Frostbite can be treated with vitamin E ointment, 10% camphor ointment and tincture of chili pepper if the frostbite is not broken. For frostbite, use 5% boric acid ointment, erythromycin ointment, Bactrim ointment, lard and honey ointment, etc. Severe cases need to go to the hospital for medical consultation.
