Blisters

Read more about...

We all get blisters at one time or another, whether from local irritation, burns, insect bites, allergic or drug reactions, infection, trauma, or illness. These little balloons are nature's way of insulating damaged skin under a coating of clear fluid. Medically speaking, if the size is less than 1/5 inch in size it is called a vesicle; otherwise it qualifies as a blister. Blisters are most common among people who have difficulty finding shoes that fit properly and athletes who may be running or walking long distances.

The fluid inside a blister is serous fluid, which means that its composition is same as that of the clear portion of the blood. As long as a blister is intact, its contents are sterile, and the underlying tissue is protected against infection. Therefore the longer you can keep the blister intact, the better off the tissue beneath.

Preventive measures for blisters

Many marathon runners use a layering technique to prevent blisters on their feet. Begin with a pair of shoes that are slightly big for your feet. Apply petroleum jelly to your feet, then put on a pair of thin socks. Then put on a pair of thicker athletic socks before putting on your shoes. Many runners and hikers apply New Skin spray before activity they might lead to blisters.
