Cold Weather and Cold Sores
It’s that time of year again when dry skin and chapped lips become problems. Some of you may also deal with cold sores around the start of the winter season. So, what exactly triggers cold sores?
The small blisters on your lips or in your mouth are actually caused by a virus called herpes simplex virus-1. The virus can lie dormant in your body for years and can be triggered by other infections, stress, cold weather and even certain foods. Ultimately, the cause is unpredictable, as well as the triggers that reactivate the virus. Don’t let the name fool you either. It doesn’t take having a cold or sniffles to develop a cold sore.
These painful blisters are extremely contagious, so be very careful when they appear. Their underlying virus is spread through direct skin contact. So you’ll want to give hugs instead of kissing. They can also be spread by sharing a cup, eating utensils or lip balm even when you can’t see a sore.
Thankfully, cold sores normally go away within 7 to 10 days. But there’s no way to make the infection go away completely. It’s important to see a doctor if you have another health condition that has weakened your immune system. Also consult a doctor if the sores don’t heal by themselves within 7 to 10 days, you get cold sores often, or you have signs of a bacterial infection.
