Introduction
The area bitten by a mosquito feels hot. This can be managed by applying cold compresses to reduce heat, cleaning the area and relieving itchiness, avoiding scratching, using topical soothing products, and monitoring changes in symptoms. The reaction is a localized inflammation caused by mosquito saliva, and proper care can quickly alleviate it. If the hot area spreads, or if pus develops or systemic fever occurs, prompt medical attention is recommended.
The area bitten by a mosquito becomes hot; this can be managed through methods such as cold compresses, cleaning and relieving itching, avoiding scratching, applying soothing topical products, and monitoring symptom changes. The heat results from a localized inflammatory reaction caused by mosquito saliva, which can be quickly relieved with proper care. If the affected area expands, pus develops, or systemic fever occurs, prompt medical attention is recommended.
1. Cold compress: Wrap an ice pack or a cold, wet gauze in a clean towel and apply it to the affected area for 10–15 minutes per session. This helps constrict blood vessels, reduce inflammation, and rapidly alleviate the sensation of heat.
2. Clean and relieve itching: Wash the bite area with running water and mild soap to remove residual mosquito saliva and reduce irritants. Avoid washing with hot water, as it may worsen local congestion.
3. Avoid scratching: Scratching damages the skin barrier, increases the risk of infection, and may exacerbate inflammation spread. Relieve itching by gently tapping the area or distracting yourself to minimize irritation to the affected site.
4. Apply soothing topical products: Use gentle products such as calamine lotion or cooling anti-itch creams. Apply a thin layer to the affected area to achieve astringent, anti-itch, and anti-inflammatory effects. Avoid strong, irritating corticosteroid creams.
5. Monitor symptom changes: Pay attention to the extent of redness and swelling and the level of pain at the bite site. If symptoms fail to improve or continue worsening within a short time, be alert for allergic reactions or infection, and take appropriate action promptly.
In daily life, take preventive measures against mosquitoes, avoid going outdoors during peak mosquito activity times, keep the skin clean and dry after bites, wear loose, breathable clothing to reduce friction, and maintain a light diet avoiding spicy or irritating foods to support skin recovery.
