Creates histamines to attack the saliva of a mosquito
Itching is the body’s way of taking action to protect you from the mosquito’s saliva. “When a mosquito bites us, our body’s immune system creates histamines, causing the skin around the mosquito bite to itch,” explains Dr. Renee Matthews of Chicago, Illinois.
“Your lymphocytes [a type of white blood cell] will go to where the bug bite is to try and kill the saliva off,” adds Dr. Christopher Hollingsworth of NYC Surgical Associates. “This is then why your body creates a swelling bump that is itchy.”
