Herpes is a viral infection caused by the herpes simplex virus (HSV) . After a person is first infected, the virus travels to nerve cells near the spine and stays there. When there is a trigger, the virus can become active again, causing a new outbreak of sores and blisters. Triggers can vary from person to person, but some common ones include:

• Illness: A weakened immune system due to illness can trigger a herpes flare-up.

• Stress: Emotional stress can also trigger a herpes outbreak.

• Hormonal changes: Hormonal changes, such as those that occur during the menstrual cycle, can affect genital herpes outbreaks.

• Friction: Some people find that the friction of sexual intercourse irritates the skin and brings on symptoms.

• Physical trauma: Trauma to the body, such as having surgery, may make herpes symptoms appear.

• Exposure to cold or sunlight: While the common cold and sunlight seem to trigger outbreaks of oral herpes (cold sores), there is no proof that they trigger genital herpes outbreaks.

Its important to note that triggers may not be the same for everyone, and doctors are not certain how much lifestyle affects herpes symptoms. If you think a particular trigger is causing your symptoms, its best to discuss it with your doctor to determine the best course of action.
