Infection caused by the herpes simplex virus, mainly localized around the mouth, can lead to blisters called cold sores. These sores sometimes get itchy and red and are very painful if the blister breaks. The virus might be present without causing visible symptoms. But there are a few triggers that can cause the blisters to appear. Tips for preventing these triggers would be the most reliable preventive tips for cold sores.

1. Avoid the common transmission channels
Shared razors, cigarettes, lipsticks, or even drinking glasses can directly transmit the virus from one person’s mouth to another. One of the essential preventive tips for cold sores is to avoid all these transmission methods.

2. Curb sun exposure
Exposure to direct sunlight could be one of the common triggers. If you are stepping out of the house, and if you know that you would be exposed to sunlight, it would be a good idea to use a good sunscreen. Sometimes, it is also triggered due to artificial UV light sources. One of the common sources of UV light would be a tanning bed. Avoiding exposure to UV light would prevent cold sores.

3. Keep stress under control
People who are already carrying the virus without developing blisters might sometimes find stress to be a trigger. Quick and easy ways to relax will help to keep your everyday stress levels low and prevent cold sore episodes.

4. Ensure that your immune system is healthy
Several diet and fitness habits can influence how well your body’s immune system is functioning. Cold sores often do not develop if your immunity can fight off the infection and prevent the occurrence of blisters. So, focus on creating a healthy meal plan that strengthens your natural immunity.

5. Maintain the moisture levels of your lips
Dry and chapped lips can be triggers for cold sores. Using an intensely hydrating lip moisturizer every day would help in preventing dryness and prevent these blisters. Another problem could be cracked lips or dryness due to excessive biting of the lips. Using a nourishing lip balm and avoiding the habit of biting the lips would also be effective in lowering the risks of visible blisters.

6. Lysine for cold sores
This is a type of amino acid that the body receives from the diet to treat cold sores and prevent them. This amino acid might be prescribed in the form of topical cream or as a dietary supplement.

With these preventive tips for cold sores, you can reduce the intensity of visible symptoms of the infection. The condition often settles down on its own without medical intervention, but the sores can sometimes be itchy or painful. Preventing the triggers would be the best way to avoid discomfort.
