5 Common Triggers for Cold Sores

Cold sores are a common viral condition that can be both uncomfortable and unsightly. They are caused by the herpes simplex virus (HSV), which remains dormant in the nerves until certain triggers prompt an outbreak. Knowing what these triggers are can help you avoid them and minimize the frequency of cold sore outbreaks.

What Is a Cold Sore?

A cold sore is a viral infection characterized by small, painful fluid-filled blisters or sores that appear on or around the lips, mouth or nose. They are caused by the herpes simplex virus (HSV), which can be easily transmitted through close personal contact, such as kissing or sharing utensils. Cold sores are a common condition, and while they are not usually serious, they can be uncomfortable and unsightly. Cold sores usually last for a few days to a couple of weeks and can recur throughout a person’s life.

What Makes A Cold Sore Reappear?

Our professional team at Kayal Dermatology & Skin Cancer Specialists in Marietta, GA, discuss five common triggers for cold sores.

1. Stress

Stress is one of the most common triggers for cold sores. When you’re under stress, your body produces more cortisol, a hormone that can weaken your immune system. This can make it easier for the herpes virus to reactivate and cause cold sores. To reduce stress, try practicing relaxation techniques such as meditation, yoga or deep breathing.

2. Sun Exposure

Exposure to sunlight can also trigger cold sores. UV radiation can weaken your immune system and make it easier for the herpes virus to reactivate. To reduce your risk of cold sore outbreaks, wear a broad-spectrum sunscreen with an SPF of at least 30 whenever you’re outside.

3. Illness

When your immune system is weakened due to illness, the herpes virus can reactivate and cause cold sores. Common illnesses that can trigger cold sores include the flu, a cold and other respiratory infections. To reduce your risk of cold sore outbreaks, take steps to protect your immune system, such as getting enough sleep, eating a healthy diet and staying hydrated.

4. Hormonal Changes

Hormonal changes can also trigger cold sores, particularly in women. This is because the hormonal fluctuations that occur during menstruation, pregnancy and menopause can weaken the immune system and make it easier for the herpes virus to reactivate. If you experience frequent cold sore outbreaks during these times, talk to your Kayal Dermatology specialist about potential treatment options.

5. Injury to the Lips or Mouth

Injury to the lips or mouth, such as a cut or burn, can also trigger cold sores. This is because the herpes virus can enter the body through a break in the skin. To reduce your risk of cold sore outbreaks, take steps to protect your lips and mouth, such as wearing lip balm with SPF and avoiding hot foods and beverages.
