10. The Science Behind Mosquito Bites and Itching
Mosquito bites itch because of the immune response to proteins in mosquito saliva. The mosquito pierces the skin and injects saliva to prevent blood clotting. The immune system reacts by releasing histamines, which increase blood flow and white blood cell activity, causing inflammation, redness, and itching.
Understanding this explains why remedies like heat can effectively reduce symptoms.
