Laiwo Medical: Knowledge Sharing: Why Scars Itch and Pain When Summer Comes
Publish Date： 2024/7/26
In summer, many scar sufferers have headaches because the scars on their bodies are about to start acting like demons, causing both pain and itching, which is very uncomfortable. Especially when sweating, it is extremely painful and itchy, neither scratching nor scratching, and it is a great torment. So what exactly makes scars so 'active' in summer?
Accelerated blood circulation
When it is hot, the blood circulation in the human body accelerates and metabolism is vigorous. This physiological change leads to an increase in blood flow to the scar area, which in turn stimulates scar tissue and causes itching. This physiological stimulation makes scars appear particularly "sensitive" in summer.
Sweat stimulation
The high temperature in summer makes it easier to sweat, and the sodium oxide and potassium chloride in sweat can stimulate the nerve endings of scars, exacerbating the pain and itching of scars. Faced with this discomfort, many people unconsciously scratch, but often it backfires, causing scars to be doubly stimulated, triggering inflammatory reactions in connective tissue and accelerating scar growth.
Climate and humidity
The high temperature and humidity in summer not only lead to more vigorous sebum secretion, but also may cause the inability of keratin to peel off normally, pore blockage, and easily lead to the growth and itching of scar lumps. In addition, strong ultraviolet rays in summer make damaged scar skin more prone to excessive secretion of melanin, leading to increased pigmentation in the scar area, increasing the difficulty of repair, and possibly exacerbating the itching and pain of scars.
How to relieve itching and pain in scars
Keep clean and dry
Scar areas should be regularly cleaned to remove sweat and dirt, keeping the skin clean and fresh. Avoid using irritating cleaning products to avoid exacerbating itching.
Ice compress or hydrotherapy
Gently apply ice packs or cubes on scars for no more than 10 minutes each time, which can effectively reduce local temperature and alleviate symptoms. Alternatively, take a warm shower or bath to relieve discomfort in the scar area, but it is important to control the water temperature to avoid overheating, burns, or cold stimulation.
Drug treatment
Under the guidance of a professional doctor or dermatologist, apply scar removal drugs containing growth factors, collagen, and other ingredients that promote scar repair. Please make sure to choose the appropriate mitigation method based on your personal situation.
