As these sweat glands change into clogged with excessive sweating on a very popular day, they don't function properly and red itchy patches form.
- Grover's disease, Small, red, itchy spots on the chest and back can be triggered or worsened by overheating and sweating. Often it clears up inside a couple of weeks or months. Symptoms can persist for years, with less frequent flare-ups in the summertime months.
- Eczema is a chronic skin condition characterised by dry, itchy plaques that affects tens of millions of individuals within the United States. Sweating During heat waves may cause irritation and inflammation of the skin, exacerbating the symptoms of eczema. Dehydration as a result of fluid loss through sweat could make the skin more at risk of eczema flare-ups.
- Russia, It can be sensitive to heat, which causes facial redness, blood vessels and acne-like breakouts. Heat causes blood vessels to dilate because the body tries to chill itself down, leading to redness and swelling. High temperatures, especially combined with sun exposure, may cause flare-ups.
- Melasma. Hyperpigmentation disorders corresponding to melasma are also worsened by heat. Melasma is characterised by irregular dark spots on the face and is commonly triggered by UV exposure from the sun. Heat can increase the activity of melanocytes, the cells that produce pigment, making these patches more visible. Additionally, the combined effects of warmth and UV rays speed up the degradation of collagen and elastin, causing the skin to lose its elasticity.
- Risk of skin cancer Increases with increasing exposure to UV radiation. Heat waves – now starting earlier, ending later, and lasting longer – contribute to UV exposure, especially amongst individuals who work outdoors. And preliminary research suggests. Prolonged exposure to high temperatures May increase the danger of skin cancer. This might be of particular concern to firefighters, who're exposed to extreme heat.
Heat waves, air pollution and skin
During heat waves, levels of Environmental pollution As ozone and particulate matter may increase. And a response occurs between these pollutants, heat, and UV radiation. Secondary pollution corresponding to peroxyacetyl nitrates (PANs). Such pollution can irritate the skin and contribute to inflammation through oxidative stress and DNA damage, so inflammatory conditions like eczema and rosacea can worsen.
