Why does the skin itch when bitten by a mosquito?

The most disturbing "guests" of summer are mosquitoes. When they bite, redness, swelling, and itching appear on the skin. But what is the reason for this situation?

When a mosquito bites, special mucus - slurry - enters the skin through its mouth. Its function is to stop rapid blood clotting. However, the human body perceives this substance as "foreign" and produces a substance called histamine. Histamine dilates capillaries, causing our skin to redden and itch.

Interestingly, each person has a different reaction to mosquitoes:

  • Someone only feels a slight flush.
  • Others experience severe itching and large swelling.
  • Perhaps you've also observed that some people "don't like flies" - they barely sting them. This is due to the difference in biochemical substances in the body.

What should be done?

  • Applying a cold compress reduces itching.
  • Antihistamine ointments or gels provide relief.
  • A solution of honey or baking soda is also a folk aid.

Therefore, know that itching when bitten by a mosquito is the body's natural defense reaction.
