The 6 Worst Habits For Your Heart from yahoo.com

Being Glued to the Tube. Spending too much time parked in front of the TV can actually be fatal, according to a 2011 study published in Journal of the American College of Cardiology. The researchers found that people who devoted four or more hours a day to screen-based entertainment—mainly watching the tube--had double the risk of a major cardiac event resulting in hospitalization, death or both, compared to those who spent less than two hours daily on these activities.

Having a Negative Attitude. While stress and depression have long been linked to higher heart disease risk, a new Harvard review of more than 200 earlier studies, published this month in Psychological Bulletin, highlights the benefits of turning that frown upside-down: An optimistic outlook may cut heart disease and stroke danger by 50 percent.

Ignoring Snoring. Frequent loud snoring can trumpet obstructive sleep apnea (OSA), a dangerous disorder that magnifies heart attack and stroke risk, if untreated. OSA (bouts of interrupted breathing during sleep) frequently goes undiagnosed because people don’t recognize the symptoms, which include waking at night for no apparent reason and unexplained daytime drowsiness. If you fit this profile, ask your doctor to order a sleep study.

Gum disease affects nearly 50 percent of Americans, many of whom don’t know they have it, because in the early stages, it’s painless.

Smoking. Even a Little Smoking even one cigarette a day increases the threat of heart attack by 63 percent and smoking 20 or more cigarettes a day more than quadruples it.
