Does the wound heal quickly in cold weather or easily in hot weather?

The higher the local temperature and humidity of the wound, the easier it is to be infected. When the temperature is lower than 28℃, the ability of tissue regeneration will be reduced, which will also affect wound healing. The drier the local wound is, the less likely it is for tissue regeneration.

There are several factors that affect wound healing:

1, age: The older you are, the worse your tissue regeneration and repair ability will be, and the slower your wound will heal;

2. Nutrition: Tissue regeneration and repair need certain nutrition. When the elderly are malnourished (lack of protein, vitamins and trace elements) or have poor appetite and eat less, they can't provide the needed nutrition or part of the nutrition to the tissue, which will delay the wound healing;

3. Diseases: such as diabetes, hypoproteinemia, anemia, autoimmune diseases, tumors, etc.

4. Drugs: anticoagulants, immunosuppressants, cytostatics, hormones, etc. It will inhibit cell proliferation and affect tissue repair;

5. Psychology: Long-term tension, depression and anxiety of the elderly, and the disorder of neuroendocrine system will affect the immune system of the body, thus indirectly affecting wound healing;

6. Infection: excessive inflammatory reaction of local tissues can easily cause necrosis of tissues and cells and hinder wound healing.

Extended data

The cuticle of the elderly skin becomes thinner, the skin becomes dry and fragile, and even xerosis occurs, which leads to itching, chapping and scaling, which is easy to cause skin damage and infection. It is recommended that you take a bath no more than three times a week, and use warm water, soap and other less irritating cleaning products. After bathing, you should use oily cream skin care products to ensure that your skin is moist and do a good job of daily skin self-examination.

Secondly, actively treat the primary disease to prevent complications from causing wounds. For example, reasonably control blood sugar and prevent diabetic foot; Do a good job in incontinence management to prevent incontinence dermatitis; For those who can't take care of themselves, they need nursing staff to help them turn over every 2 hours to prevent pressure ulcers; Patients with unexplained lower limb swelling, intermittent claudication or resting pain should seek medical advice in time to be alert to lower limb ulcers.
