A study published in the American journal Cancer found that people who frequently had some types of dental X-rays in the past had an increased risk of a meningioma, the most common type of brain tumor.
It should be noted that their data was from a time when radiation doses with typical X-rays were higher than they are today, given that many dentists are moving from traditional film to digital images. Read more about Brain Tumors Linked to Frequent X-Rays

In the wake of the tragic passing of actress Natasha Richardson, I'd like to share a few details on head injuries that everyone should know about.
Based on what I've read in several newspaper reports, Natasha Richardson died from an epidural hematoma, which medical professionals will tell you is one of the most frightening conditions around because it can be caused by a low force blow to the head, and also because initially, there may be no signs to indicate that a serious injury has occurred.

It's estimated that 10 million Americans suffer with noise-induced hearing loss. In fact, noise is one of the most common occupational hazards today, with as many as 30 million Americans being exposed to harmful noise levels at work.
We register sound through little hairs that vibrate in our inner ears in response to different noises. When these hairs are exposed to a sudden burst of very loud noise or to a steady stream of fairly loud noise, they can get damaged, resulting in hearing loss.

Dr. David Phillips, professor of sociology at the University of California in San Diego published a study in 2008 that highlighted an alarming trend: From 1983 to 2004, while deaths caused by firearms, fires, drownings, and traffic accidents decreased, the rate of deaths from prescription and over-the-counter drugs increased at a rapid clip.

The other day, I was driving along a semi-busy road when I noticed that the driver of an oncoming SUV was clearly texting away on her cell phone. I instinctively hovered my right foot over the brake and did the same with my right hand over the horn, ready to swerve and honk if needed. Read more about Defensive Driving Tips for the Texting Era
If you chew gum on a regular basis, please consider the following:
Chewing gum causes unnecessary wear and tear of the cartilage that acts as a shock absorber in your jaw joints. Once damaged, this area can produce pain and discomfort for a lifetime.
You use eight different facial muscles to chew. Unnecessary chewing can create chronic tightness in two of these muscles, located close to your temples. This can put pressure on the nerves that supply this area of your head, which can lead to chronic, intermittent headaches.
