- Why scratching a mosquito bite makes it so much worse, according to science
A University of Pittsburgh study found that scratching mosquito bites or rashes activates mast cells, increasing inflammation and prolonging the itch. Experiments on mice showed scratching released substance P, worsening allergic reactions, though it temporarily reduced Staphylococcus aureus bacteria. Researchers concluded chronic scratching's harms outweigh its benefits.
- Scratching that bug bite might feel good at first but science explains why it’s a bad idea
Scratching bug bites worsens inflammation and itchiness, according to research on mice showing that scratching triggers immune responses. Studies by Dr. Daniel Kaplan’s team found that preventing scratching reduced swelling and inflammation, suggesting scratching disrupts skin healing.

Scratching bug bites or rashes can worsen inflammation and itching due to immune system reactions. A study using mice showed that scratching triggers mast cells to release histamine and other compounds, increasing swelling and itchiness. Researchers found that mice unable to scratch had less inflammation, suggesting scratching exacerbates skin issues.
