Cold Sores can be linked to dry winter weather; which is linked to reactivate the HSV-1 virus responsible for the sores.
Here are some of the most common reasons why the winter weather is to blame for cold sore outbreak!
1. Harsh dry cold wind can dry lips and mouth making it vulnerable to the virus.
2. Lack of sunshine and vitamin D weakens the immune system.
3. Holiday planning can increase stress, which triggers HSV-1 outbreak.
4. Other illnesses such as flu and cold also weakens immune system making the body more vulnerable to the virus.
Cold sores are also called fever blisters; they look like pimples or blisters formed around the mouth. They are caused by herpes simplex virus-1, or HSV-1. They are contagious; so avoiding to share food, utensils or direct contact of the affected area can help prevent the outbreak.
Cure and Prevention: Cold sore blisters usually heal in a week by themselves. Over-the-counter topical anesthetics can provide relief. We can also prescribe antiviral drugs to reduce these kinds of viral infections.
Besides, reducing stress, working on boosting immunity, avoiding harsh cold wind and keeping lips moistened may help prevent sores from spreading.
