Urticaria (hives) is not directly caused by an infection, but is a common allergic reaction. It is usually triggered by an overreaction of the immune system when the body comes into contact with certain substances or is in a specific state. If you experience symptoms, it is recommended to first check for everyday contacts and consult a doctor promptly.
Specific situations that may trigger urticaria include:
1. Food factors: Some people may experience reactions after consuming seafood, nuts, eggs, or certain food additives.
2. Environmental exposure: Pollen, dust mites, animal dander, or ingredients in certain cosmetics and detergents can all be triggers.
3. Physical stimulation: It can also be triggered when the skin is subjected to physical influences such as friction, pressure, changes in temperature or sun exposure.
4. Other factors: Mental stress, fatigue, infection, or certain medications may also be related to the appearance of symptoms.
To reduce discomfort, you can keep a record of and avoid identified triggering factors; wear loose cotton clothing and avoid scratching your skin; if symptoms recur or worsen, please seek medical attention promptly and follow the doctor's instructions for proper treatment.
