Northerners to the south long eczema

North to South eczema is mainly caused by climate differences, temperature changes, different allergens, changes in living habits and other factors. 1. Climate differences The climate in the south is relatively humid, and the humidity environment may affect the normal metabolism of the skin, leading to the weakening of the skin barrier function, which is easy to cause eczema. Northerners used to relatively dry climate, suddenly came to the wet south, the skin may be difficult to adapt to this huge change. 2. Temperature change The temperature difference between the north and south may also be a factor. Temperature fluctuations may irritate the skin, affect the skin's regulatory function, and increase the probability of eczema. 3. Different allergens exist in the environment of the south and the north. After arriving in the south, you may be exposed to some new allergens, such as certain plant pollen, mold, etc. The stimulation of these allergens may induce eczema. 4. Living habits may change when you arrive in the south. For example, you may try more local foods in your diet, some of which may become factors that induce eczema. At the same time, your routine may also change due to environmental changes, which may affect your immune system and increase the risk of eczema. When eczema occurs, seek medical attention in time, take appropriate treatment measures, and pay attention to adjusting living habits and environment to promote the recovery of eczema and prevent recurrence.
