Cold sores are a common annoyance for the majority of people. If you’ve wondered what causes cold sores and triggers flare-ups, we’d love to help you understand this so you can best care for yourself. At the Center for New Medicine in Irvine, CA, we help patients understand the factors that trigger cold sores and how to manage them effectively.
What Are Cold Sores?
Cold sores, also known as fever blisters, are small fluid-filled blisters that usually appear on or around the lips. They are caused by the herpes simplex virus (HSV), most commonly HSV-1. While many people carry the virus, it doesn’t always cause visible symptoms. Understanding what causes cold sores can help individuals prevent outbreaks and manage symptoms when they occur.
Common Causes of Cold Sores
If you’re trying to understand what causes cold sores, it’s important to recognize the triggers that can activate the herpes virus. These triggers vary from person to person but often include the following:
- Stress: Physical or emotional stress can weaken the immune system, making outbreaks more likely.
- Illness or Fever: A cold, flu, or other illness can trigger cold sores.
- Sun Exposure: Ultraviolet (UV) light can reactivate the virus in some individuals.
- Hormonal Changes: Menstrual cycles, pregnancy, or other hormonal shifts may trigger outbreaks.
- Injury or Trauma: Biting your lip, dental work, or other injuries to the mouth area can initiate a cold sore.
By understanding what causes cold sores, you can identify your personal triggers and take preventive measures.
How the Herpes Virus Works
The herpes simplex virus that causes cold sores remains dormant in nerve cells after the initial infection. When triggered by one of the factors above, the virus travels along nerve pathways to the skin’s surface, leading to the development of cold sores. Knowing what causes cold sores helps explain why outbreaks may appear periodically and why they may vary in severity.
Symptoms of Cold Sores
Recognizing the symptoms of cold sores can help you take action early. Common signs include the following:
- Tingling, itching, or burning around the lips before a sore appears
- Small fluid-filled blisters on or near the lips
- Pain, discomfort, or sensitivity in the affected area
- Crusting and healing after a few days
Early recognition of symptoms is key, especially if you want to manage outbreaks effectively.
Preventing and Managing Cold Sores
Understanding what causes cold sores is the first step in prevention. While you may not be able to eliminate the virus entirely, you can reduce the frequency and severity of outbreaks. Strategies include the following:
- Managing Stress: Incorporate relaxation techniques, exercise, and adequate sleep into your daily life.
- Protecting Your Lips from the Sun: Use lip balm with SPF when outdoors.
- Boosting Immunity: Eat a balanced diet, stay hydrated, and consider immune-supporting supplements.
- Avoiding Triggers: Track outbreaks to identify personal triggers such as certain foods or hormonal changes.
Red Light Therapy for Cold Sores
