湿疹可能是“干”出来的 冬季皮肤瘙痒需警惕

Group 1 - Eczema is a skin inflammation reaction characterized by severe itching, caused by various internal and external factors, and can be classified into acute, subacute, and chronic phases [4] - The core issue of eczema is the damage to the skin barrier function, rather than humidity as the name suggests [5] - Summer is a peak season for eczema due to hot and humid conditions weakening the skin barrier and increased exposure to allergens [7][9] Group 2 - Winter is also a high incidence period for eczema, with dry conditions leading to skin dehydration and barrier dysfunction [9][12] - Symptoms of winter dry eczema include dryness, flaking, and redness, often affecting the lower legs and thighs, and can lead to severe itching [13] - The skin's sensitivity and inflammatory response threshold decrease, making it easier for minor irritations to trigger itching and rashes, creating a vicious cycle of "itch-scratch-inflammation" [15] Group 3 - Special attention is needed for the elderly and children, as their skin's lipid secretion is either declining or not fully developed, making them more vulnerable to winter dryness [17] - Daily protective measures against eczema include avoiding scratching, maintaining good bathing habits, and using moisturizing products [17][20][28] - A balanced diet, regular exercise, and wearing breathable clothing can also help in managing eczema symptoms [22][24][26]
