The causes of cold sores are unknown. A virus called the herpes simplex 1 is the main cause of cold sore outbreaks for most people. This virus is not a very common virus, but it does cause outbreaks when it is reactivated. Most of the time the virus is reactivated after an injury or surgery. When this happens, the body will release a lot of the protein that causes cold sores as a defense mechanism.
However, there are cases where the herpes virus does not reactivate because it is missing one of its protein components called the arginine. When the arginine is not present in the virus, the body cannot properly break it down or make it inactive. Therefore, the body will reactivate the herpes virus and produce cold sores because of the lack of arginine.
Other causes of cold sores could be due to allergies and eczema. Sometimes these causes are related to genetics or the immune system. If your mother or father had an infection like herpes simplex virus, then you are at risk for catching it as well. However, this can still happen if you have poor immune system, which means you are more prone to catching this condition.
A person’s sensitivity to sun can also cause the herpes to spread from person to person. Many people experience a breakout after they just came out from sun. This is because sun is a good medium for the virus to create millions of viruses, which then attack the body. However, it can be hard to get rid of the herpes if you already have it, so you may have to wait until it’s completely healed. If you have sensitive skin, you should stay away from sun and wear sunscreen to protect yourself from possible outbreaks.
You can also suffer from cold sores due to a severe fever. In order to help reduce the pain, you can use ice, but you should always keep in mind that fever is a very serious condition and you should consult a doctor if you feel something is wrong. The burning sensation can also be a symptom of other diseases like diabetes, AIDS or mononucleosis. It’s important that you always seek medical attention when experiencing a burning sensation in your mouth or around your face.
These are just some of the main causes of cold sores, which you should know about. If you want to prevent the virus from spreading and to keep the blisters from appearing, then you should stick to a healthy lifestyle and eat healthy foods. If you feel that stress is a factor in your outbreak, you should try relaxing activities like yoga or meditation, which can help relieve stress and anxiety. In addition to that, you can also apply ice to the infected area to help reduce the pain and inflammation caused by herpes.
