The hows and whys of preventing cold sores

They always say prevention is better than a cure, but the problem with cold sores is that prevention really is the best option as there is no cure yet. Naturally it is better to avoid catching the virus that causes them, but if you do become infected it isn't the end of the world as you can take steps that help in preventing cold sores.

Looking after the immune system is vital in this, which may mean making some lifestyle changes. Take a long hard look at what you eat and drink to start with. A good balanced diet, low in fat and sugars and with plenty of fresh fruit and veg is ideal. And if you need to lose weight, do it, while taking regular exercise will help enormously in boosting your immune system and preventing cold sores from occurring so frequently or severely.
