Prevent Recurring Cold Sores

Cold sores or fever blisters are usually filled with fluid and painful, and normally appears in the mouth or on the lips. The development of cold sores is due to the activation of the virus known as herpes simplex virus and its recurrence can be triggered by certain conditions. Take note that various situations can cause the body’s immune system to weaken and this can activate the virus and trigger an outbreak.


Stress is considered as one of the major factors that can trigger cold sores. The stress hormone known as cortisol can directly affect the body’s immune system by suppressing it, thus resulting to an inflammation. Experts believe that the release of certain chemicals during the acute or chronic period of stress is the main reason why the body’s immune system is compromised, thus resulting to a herpes cold sore outbreak.

Fever and Illness

During an acute health condition, such as flu or cold, the body’s immune system becomes vulnerable to harmful pathogens and this can inhibit the production of antibodies, which are responsible for killing harmful elements in the body. These antibodies are responsible for keeping the cold sore virus dormant and insufficient amount of antibodies can give the virus a chance to cause an outbreak.


Immunosuppression is considered as what causes cold sores. Based on a certain study approximately 10% of all patients afflicted by the herpes virus experience cold sore flare-ups as a result of excessive exposure to direct sunlight. That is the reason why it is necessary to use sunblock lotions when going out, even if you are unaware that you are infected by the herpes virus.

For cold sore symptoms, home remedies and medications might be necessary for alleviation. These remedies and medications may not be able to eliminate the virus, but these are helpful in relieving the pain and itching due to the condition.

    Mine comes back all the time. I take proper diet and vitamins, but I guess, it’s because of stress. I need to have strong immunity to resist this, but I also need a stress free life.
