Cause: Impaired Blood Circulation
Impaired blood circulation is a common cause of worsening discoid eczema. Some individuals with this condition also suffer from stasis dermatitis, which compounds the problem. Stasis dermatitis primarily affects adults who already have a circulation issue, leading to difficulties in blood flow to the lower legs. The skin, even in healthy individuals, receives only 1.7 percent of the blood flow from the heart, which is significantly less oxygen compared to other organs and tissues. As a result of poor circulation, the skin’s natural defense mechanisms against eczema become weakened, exacerbating the condition.
Causes: Cold Winter Weather
During the winter season, the skin tends to lose its natural moisture. The heating systems employed to keep our homes warm often deplete the air of moisture, leading to a similar effect on our skin. Additionally, taking hot showers further exacerbates this problem by stripping the skin of essential moisture and natural oils. As a result, the outer layer of the skin can feel dry and itchy, even for individuals without eczema. However, those with nummular dermatitis need to be especially mindful of preserving moisture in their skin.
