How to Reduce Swelling After a Mosquito Bite: These Itch-Relief Methods Are Worth Trying

When a mosquito bites, it injects saliva into the skin, and substances in the saliva stimulate the human immune system, causing local redness, swelling, itching or a slight bump; this is why a mosquito bite becomes swollen. Most people have a relatively mild reaction, which usually resolves on its own within a few hours to one or two days, so there is no need to be overly nervous.

To reduce swelling as quickly as possible, first wash the bitten area with clean water or soapy water to keep the skin clean and reduce irritation. Then apply a cold compress with a cold towel or a towel wrapped around ice for a few minutes; the low temperature can constrict local blood vessels and relieve swelling and itching. Be careful not to let the ice come into direct contact with the skin.

When the swollen bump itches, try to resist scratching it. Breaking the skin can easily cause infection and will also make the redness and swelling last longer. When the itching is obvious, you can apply common topical anti-itch medicines such as calamine lotion. Children and people with sensitive skin should preferably consult a doctor before use. If the area of redness and swelling continues to expand, blisters or pus appear, or systemic symptoms such as fever occur, seek medical attention promptly.

Only by doing a good job of mosquito prevention in daily life can you reduce the chance of being bitten at the source. Promptly clear standing water in and around the home, use window screens, mosquito nets and mosquito repellent products together, and you can also grow some plants with mosquito-repellent scents on a balcony or in a courtyard to make it harder for mosquitoes to come near.
