8. Allergies
Allergies are caused when a person’s immune system abnormally attacks an otherwise harmless substance. While some people’s immune systems are overreactive and target pet dander, pollen, or peanuts, others do not react.
This change in the person’s immune system can create the perfect conditions for once-dormant herpes to come into play and cause cold sores to form. Attempting to control the allergy with over-the-counter medication may help.
