Why does a mosquito bite turn a large area purple?

Mosquitoes are a relatively common creature in our daily life. Because of their large presence, people face a greater risk of being bitten. Almost everyone has been bitten by mosquitoes, causing various lumps on the skin, which are itchy and painful. Some people will develop a large purple area after being bitten by mosquitoes, which makes people feel very uncomfortable. Let’s take a look at why a large area turns purple after being bitten by mosquitoes.

The reason why mosquito bites turn purple is that there is a substance in the mosquito's saliva that has vasodilation and anti-coagulant effects, which makes it easier for blood to flow to the bite, resulting in symptoms of blisters and itching.

The itching occurs because the body's immune system releases a protein called histamine to fight against foreign substances, and this immune response triggers an allergic reaction at the bite site. Histamine causes swelling of the tissue around the bite as blood flows to the bite to speed up tissue recovery.

Ways to relieve itching:

1. After being bitten by a mosquito, it is very itchy. It is best to wash the affected area with soapy water or clean water.

2. Apply or soak the itchy area with salt water, which can soften the swelling and effectively relieve itching.

3. Use sliced ​​garlic. Rub the mosquito bite repeatedly for one minute, which has obvious analgesic, itching and anti-inflammatory effects.

Daily mosquito repellent methods

1. Eating garlic can effectively repel mosquitoes, because mosquitoes do not like the smell of garlic secreted by the human body. You can also put a few garlic heads indoors to repel mosquitoes.

2. Oral vitamin B is excreted from the body through sweat after being metabolized by the human body, and it will produce an odor that mosquitoes dare not approach. The dosage is to take 1 to 2 tablets of vitamin B1 orally one hour before going to bed, but do not take it in large quantities for a long time.

3. Some people are often bitten by mosquitoes, but people around them don’t feel anything. It turns out that mosquito bites have a lot to do with the color of clothes people wear. If you wear dark blue or brown clothes, you are more likely to be bitten by mosquitoes. So you should wear light-colored clothes in summer.

4. Place two or three opened bottles of cooling oil, wind oil, etc. near you. Mosquitoes will be scared by the smell and dare not come to "invade". However, the effect is slightly worse, and the cooling oil and wind oil evaporate very quickly.

5. Use jasmine, Milan or rose, preferably tuberose.
