Causes of cold sores

1. Stress:

Are you stressed emotionally or physically? Then you need to beware! Along with other health issues, stress can also aggravate the condition. Cold sores due to the herpes virus resurface under stress. When one is stressed, his/her immune system suffers. This tends to give a dormant cold sore virus a chance to replicate itself and create havoc in the form of blisters.

2. Fatigue:

Unable to do the daily chores with ease? Are you fatigued all the time? Then, you have to be careful now. Feeling tired can make you susceptible to this condition. Low energy can be taxing for the immune system, and your body will not be able to stay healthy with viruses, including the cold sore virus.

3. Chilly weather:

Did you know that that cold weather can give you a tough time. Cold weather can aggravate the cold sores problem. Fluctuating temperatures and air moisture will affect the body’s ability to keep the virus from producing blisters. The dry air and colder temperature will dry out the lips and cause the outbreak of blisters.

4. Hormonal imbalance:

You will be shocked to know that hormonal fluctuations during menstruation can lead to these. Some women may notice these eruptions just before the periods start.

5. Low immunity:

Is your immune system weaker? Then, you may probably get cold sores. The cold sore virus tends to live inactive in one’s mouth area in nerve cells. But the immune system sees to it that the virus doesn’t replicate and causes blisters. But, if you have a cold or the flu, and the immune system is busy dealing with other infections, then you may get cold sores.
