If you find that your fever blister re-appears again and again, it may be that you are subject to the same conditions that give rise to the cold sore symptoms and re-activates the herpes simplex virus 1. What are some of the common factors that can once again lead to that big cold sore on the lip?

1) We are hearing a lot about contaminated peanut butter lately in the news and the bacteria that has led to people and pets around the US having reactions. Tainted peanut butter products such as crackers, snacks and cookies are recalled due to the large samonella outbreaks. For those prone to the herpes simplex virus that results in the lip fever blisters, it is actually the amino acid argine is the culprit. Our amino acids need to be balanced . Peanut butter and protein supplements for weight building often have a high ratio of amino acid and this can result in a cold sore. By taking lysine as a supplement, we can re-balance this situation. Check your protein bars too for the ingredients. Chicken, eggs and fish are high in lysine . Chocolate and peanuts are high in argine.

2) Exposure to sunlight and uv radiation can trigger a cold sore. This includes using a tanning booth or tanning bed as well. UV radiation should be protected by using a spf lip balm or applying a sun block on your lip. It is best to use a sun protection factor of 30 or higher.

3) Menstruation can cause some people to have a fever blister outbreak. The hormones are very volatile around this time of the month. Be sure to get enough sleep and take care of yourself with proper nutrition so that your body is in a position to fight the virus.

4) Avoiding stress is easier said than done, but stress can be a major trigger for herpes blisters. When we are stressed out we get insufficient sleep and troubled sleep which can lower our immune system. Have a good friend to speak with or set up some counseling appointments to let go of some baggage. Use simple stretching, breathing and yoga to release tensions in your body. Gain perspective by reading stories of courage.

5) Wash your hands and try to not expose yourself to others that are dealing with the flu or a cold. Many people get a cold sore before getting sick because the body is weak and exposing yourself to germs can increase your chances to get a cold sore on the lip.

By staying conscious of some of the culprits for fever blisters you can be much safer in the future.
