There are many factors which determine a person's susceptibility to cold sores. Some people are chronic sufferers. In such situations the virus causing cold sores or herpes simplex virus (type 1), as it is known, manifests itself on the surface of the skin. It replicates on the skin and messes up a person's face in the case of cold sores on the lips. After 'cure' it becomes dormant under the skin and appears to have disappeared forever only to reappear at some other time in the form of blisters. Such recurrences of cold sores are often contributed to by high levels of stress and lack of sufficient rest.

The immune system is adversely affected by stress. Under 'normal' circumstances, the body is able to deal with many virus attacks and ward them off, including viruses causing cold sores. However a person who overworks or does not have enough sleep is likely to be infected. Stress from work related problems or family or financial problems are another recipe for infection by cold sores. People having such issues are prone to a number of stress related sicknesses. Proximity to people suffering from cold sores can trigger infection in people whose immunity levels are low.

Those suffering from cold sores can get relief through medication. There are a number of prescription medicines such as L-lysine and abreva that are available from the local chemist for treating of cold sores. The medicines and balms provide relief as the cold sores go through the period of healing. It is important at this time to ensure that a person has their "regular" intake of vitamin supplements. Natural vitamins are recommended. One should also avoid extreme weather. One should avoid exposure to too much sun light and also very cold weather. In cold weather, one should wear appropriate clothing. Sunscreen creams should be applied on the affected areas on the face when going out in the hot sun.

"Prevention is better than cure". In order to reduce the likelihood of cold sores, one should avoid:

1. Stress 2. Extreme weather 3. Exhaustion 4. Exposure to infected people (by being in close proximity to them)

A normal lifestyle with a balanced diet consisting of a daily intake of the recommended daily allowance (RDA) of natural vitamins and minerals is highly recommended. Sudden changes in lifestyle or eating habits are to be avoided. Multi-vitamin and mineral supplements are available from local stores. Sometimes even after eating healthy and living a stress free life, one may still end up getting an infection of cold sores. This calls for natural remedies. They work in harmony with the body without adverse effects. Melissa officinalis, better known as lemon balm is quite effective in treating cold sores. Prescription medicine can be used but it may have other side effects. With proper treatment, it is possible to reduce the recovery period to around three days.
