Sun-Induced Herpes (Sun-triggered Cold Sores)
Definition: Sun-induced herpes occurs when UV exposure triggers an outbreak of cold sores in people with the herpes simplex virus (HSV-1).
Cause: UV radiation weakens the skin’s immune response, allowing dormant herpes virus to become active.
Protection Before the Cause:
- Use lip balm with SPF to protect sensitive areas from sun exposure.
- Avoid excessive sun exposure, especially during peak hours.
Cure After the Cause: - Apply antiviral creams or take antiviral medications to manage the outbreak.
- Use cold compresses to relieve discomfort and swelling.
Conclusion: For those prone to cold sores, sun exposure is a known trigger, but prevention and prompt treatment can reduce the severity of outbreaks.
