Study Reveals Scratching's Dual Role in Worsening Inflammation and Fighting Bacteria
- Scratching aggravates inflammation and swelling in allergic contact dermatitis, according to a study published in the journal Science on January 30.
- The research used mice to show that scratching increases swelling and inflammatory immune cells, while non-scratching mice experienced milder symptoms.
- Scratching also reduces Staphylococcus aureus on the skin, but the damage to the skin likely outweighs this benefit in chronic cases.
- The study suggests that scratching has both harmful and beneficial effects, triggering inflammation while also defending against bacteria, as stated by Dr. Daniel Kaplan.
