Cold sores: small, painful, and often the cause of much embarrassment. Most of us have had the unfortunate experience of a cold sore popping up just before an important event. But why can someone get a cold sore even in the humid, year-round warmth of Singapore? Let’s dive into understanding cold sores, their causes, and effective treatment options.
What are cold sores?
Cold sores, also known as fever blisters, are small blisters filled with fluid that appear on or around the lips. They can also sometimes appear on the nose or cheeks. After they burst, they crust over and take a week or two to heal. They can be accompanied by symptoms like pain, itching, and swelling.
What causes cold sores?
Cold sores are caused by the herpes simplex virus (HSV). There are two types of HSV: HSV-1 and HSV-2. Cold sores are primarily caused by HSV-1, while HSV-2 is commonly associated with genital herpes. However, both strains can cause cold sores or genital herpes depending on where the infection is located.
Why can I get a cold sore even though Singapore is so hot?
The term "cold sore" can be misleading. The name does not imply that cold weather is the only or primary trigger. Cold sores can be triggered by a variety of factors, including:
Sun exposure: Strong sun exposure in Singapore can trigger cold sore outbreaks.
Stress: High stress levels can weaken the immune system, making outbreaks more likely.
Illness: Flu or fever may trigger cold sores.
Hormonal changes: Including menstruation or pregnancy.
Skin trauma: Chapped lips or injuries can trigger outbreaks.
Once you have the herpes simplex virus, it remains dormant in nerve cells. Various triggers can activate it regardless of climate.
How to treat cold sores?
While cold sores cannot be completely cured, various treatments can help alleviate symptoms and shorten the duration.
Antiviral medications: Over-the-counter or prescription antiviral creams or pills can help. Examples include Herpatch Herpes Cold Sore Serum and Thursday Plantation Tea Tree Cold Sore Cream.
Pain relievers: Ibuprofen or paracetamol can reduce pain.
Cold compress: Helps reduce redness and relieve discomfort.
Lip balms and creams: Keep lips moisturised to reduce risk of outbreaks.
Avoid picking at it: This prevents worsening or spreading the infection.
Sunscreen: SPF lip balms prevent sun-triggered outbreaks.
Immunity-boosting supplements: Elderberry, vitamin C, and multivitamins may help reduce recurrence. Examples include Sambucol Black Elderberry, Redoxon Triple Action, and Enervon Vitamin C.
Understanding cold sores and knowing how to manage them can significantly reduce their impact. Stress management, sun protection, and overall wellness play important roles in prevention.
