Can Old Scars Hurt In Hot Weather?
I asked Google AI, the question in the title of this post, and received this answer.
Yes, old scars can absolutely hurt or feel irritated in hot weather. Because scar tissue is different from normal skin, it doesn’t have the same elasticity, sweat glands, or ability to regulate temperature, making it highly sensitive to environmental changes.
Consult the NHS Scars Guide for general wound advice, or seek help from your local GP if you notice sudden or severe inflammation.
Several specific factors cause scars to flare up in the heat:
Nerve Sensitivity: During an injury’s healing process, nerve endings can over-proliferate or reconnect abnormally.
Changes in temperature and barometric pressure can cause these sensitive nerves to fire, leading to aching, throbbing, or tingling.
Sweat & Irritation: Scar tissue lacks normal pores and sweat glands. Sweat can get trapped and pool around the rigid, raised, or indented tissue, resulting in severe itching and localized rashes.
Skin Adhesions: The tissue beneath the scar can bind to underlying muscles or tendons. In the heat, skin and underlying tissues expand, which can tug on these adhesions and cause a pulling, burning, or aching sensation.
UV Vulnerability: Scar tissue lacks the protective melanin of normal skin. Even years later, the area is prone to burning faster and becoming hyper-pigmented,
