What Causes Cold Sores?

Cold sores are caused by a virus, called the herpes simplex virus, that invades your body and multiplies quickly, leading to painful outbreaks of clustered blisters that are filled with fluid around and inside the mouth. These sores can be very painful and disfiguring, leaving you embarrassed to go out because of these blisters. There is no cure for the virus that causes cold sores, but it is possible to minimize the number and severity of the outbreaks that you have. Common sense measures can go a long way towards preventing the virus in the first place.

Cold sores are caused by the virus, and there are many ways to prevent this from spreading and protect you from contracting the virus. The herpes virus is very contagious when there are blisters present, so avoid kissing, eating after, or drinking after anyone who shows signs of having the virus. If there are any blisters present in or around the mouth, the virus can infect others, so avoid all skin contact with anyone showing this sign. Do not share items like lipstick, lip gloss, lip pencils, chap stick, or any other items that touch skin on or near the lips, because the virus can be spread like this. It is also a good idea not to share towels or utensils, either.

Cold sores can be spread by poor hygiene, so it is important to wash your hands frequently. This is especially important before touching your face or body, as the virus can be spread to your eyes or genitals. Minimizing stress can also keep your immune system strong, helping you to fight off any threats to your health, including the virus responsible for cold sores. Make sure that you get plenty of sleep each night, and avoid sun bathing unless sun block is used. The sun can be a trigger which causes outbreaks, so make sure your face and lips are protected before going out for long periods. Regular exercise and a proper nutritious diet, including plenty of water, will not only help boost your immune system, but also help to lower your stress levels.
