6Sunscreen
Direct exposure to the sun would trigger a cold sore outbreak. Therefore, make sure to wear sunscreen containing zinc oxide around your mouth and on the lips to reduce the risk. It can also help improve the symptoms and make you feel more comfortable. Some ingredients in sunscreen may cause allergies or side effects, so make sure to read the label carefully and make an informed decision. [7]
Diet Changes
Some foods could trigger symptoms of cold sores. Thus, it is better to avoid them to reduce the risk. These include salty products, such as snacks, fried foods, and canned soups, or acidic foods, such as citrus fruits and tomatoes. Try to stop eating or limit your consumption of these foods. When eaten excessively, cold sores would show up as a result. On the other hand, you should eat more nutrient-rich foods to ensure the body gets sufficient nutrients and vitamins to fight against cold sores. [8]
