After washing the clothes and bed sheets today, I went out shopping, went to the supermarket and a restaurant, and then returned home.
After washing my clothes and bed sheets, I began to feel unwell and experienced some symptoms of an allergic reaction, such as redness and itching of the skin, as well as mild difficulty breathing. I am concerned that this might be an allergic reaction, but I am unsure whether it was caused by the laundry detergent, environmental factors, or something I ate.

Allergic reactions are usually caused by an abnormal response of the human immune system to foreign substances. In this case, the patient may have come into contact with certain allergens while shopping, such as cleaning agents, spices, pollen, or other airborne particles found in supermarkets or restaurants. After coming into contact with these allergens, the patient's skin triggered typical allergic reaction symptoms such as redness, swelling, and itching.
It is recommended that the patient immediately stop contact with possible allergens and observe whether the symptoms improve. If symptoms persist or worsen, especially if breathing difficulties increase, the patient should seek medical attention immediately. When seeking medical care, the patient should provide the doctor with a detailed account of activities and exposure history from that day to facilitate a more accurate diagnosis. Additionally, in the future, when using detergents, the patient may choose mild, fragrance-free, and dye-free products and take precautions to avoid known allergens when going outdoors.
