The difference between eczema and heat rash
Cause and site of onset
Eczema is a type of dermatitis usually caused by allergies or certain irritants, such as climate change, UV exposure, chemicals, household environment, etc. The affected areas are mostly the wrists, the bends of knees, the face, etc., and sometimes it can also spread to the whole body. Heat rash is caused by a viral infection and usually appears as a red rash on the palms of the hands, soles of the feet, and around the anus.
Symptoms and course
Common symptoms of eczema include skin itching, flushing, broken skin exuding fluid, and dry skin. In the initial stage, dark red papillary rashes will appear, which will gradually turn into vesicles and scabs. If it is not controlled for a long time, chronic eczema will form. The symptoms of heat rash are red rash and blisters, with small blisters appearing in the center of the rash. When exposed to tropical humid environment for a long time, the symptoms will worsen and form large-area blisters. Sometimes cold symptoms such as fever and headache will also appear.
Treatment methods
The treatment of eczema is mainly to control itching and prevent continued infection. Ointments or oral medications are generally used, including anti-allergic drugs, topical hormones, topical antibiotics, etc. Also avoid friction, moisture, excessive heat, rough clothing and skin irritants. The treatment of heat rash is to relieve symptoms and control infection. Depending on the severity of the condition, you can use ointments or oral liquids and other drugs, including anti-allergic drugs, anti-inflammatory drugs, etc.
Preventive measures
To prevent eczema, you must keep your skin clean, avoid irritants, control your emotions, keep the indoor air fresh, and maintain appropriate humidity. To prevent heat rash, the main thing is to control the spread of the virus, reduce the evaporation of sweat, and keep the skin dry and clean. At the same time, you should avoid strenuous exercise in high temperature and humid environments, wear breathable clothes, and ensure adequate sleep.
Summary
While eczema and heat rash are both forms of dermatitis, they differ in their causes and locations, symptoms, and treatments. Correct prevention and treatment measures can effectively curb the development and infection of the disease. If you have symptoms suspected of eczema or heat rash for a long time, you should seek medical advice as soon as possible for accurate diagnosis and treatment.
