12. Be Sun Smart

Exposure to the sun is a well-known trigger for cold sores, and so you may want to limit your exposure to the sun and use sunscreen. Remember that your skin makes vitamin D when it is exposed to the sun, so if you avoid sun take vitamin D in supplement form to prevent a deficiency. Vitamin D helps keep the immune system strong and also has anti-viral effects.
