About 50 million Americans suffer from some sort of arthritis. While simple aging is a common cause of osteoarthritis, there are other risk factors for developing the disease that you may not have known:

Drinking Coffee and Tea

Research suggests that drinking decaffeinated coffee can lead to a higher incidence of some types of arthritis, including rheumatoid arthritis. Another study suggests that drinking a lot of tea also can increase the risk of osteoarthritis and rheumatoid arthritis.

Wearing High Heels

Women who wear high heels increase the pressure on the knees, and this can lead to a higher risk of arthritis in the knee. Also, the narrow toe box with some women's shoes also can increase the chance of foot arthritis. It is a good idea to not wear heels as often in your 30s and 40s to reduce chances of developing arthritis in the feet.


Texting a lot on your cell phone can boost the chance of getting arthritis in your thumbs. All of the data has not been gathered on this risk, as arthritis can take many years to develop, but it is a good idea to give your thumbs a break.

Broken Bones

Not all broken bones can increase your arthritis risk. Most often, the risk is higher when the break is near the bone joint. It is because the joint load has changed;

Having a Lower Index to Ring Finger Ratio

People who have a smaller ratio of index to ring finger have more of a chance of developing arthritis in the knees, according to one study. There is little you can do to change this one, but you can increase your bone and joint health by not smoking and working out often.
