From drinking too much soda to slacking on the couch, iVillage rates Americans' worst habits:

Too Much TV

Americans spend 35 hours weekly sacked out in front of the tube. Experts say that encourages other harmful habits like not exercising, staying up too late and mindlessly munching.

Super-Sized Stress

Recent surveys suggest 72 percent of Americans are constantly stressed out. Experts say a lot of that is caused by sky-high expectations.

Too Much Soda

Experts say the average American downs a whopping 56 gallons of soda annually. Harvard researchers say the habit can single-handedly increase your risk of diabetes 83 percent.

Emotional Eating

Almost half of Americans regularly eat for the wrong reasons and 129 million of us are overweight as a result, according to a recent survey from the American Obesity Association.

We're Always Indoors

Scientists say being cooped up indoors raises your risk of viral infections 38 percent, and doubles your risk of insomnia, depression and obesity.

Too Much Complaining

While grumbling hardly seems like a health-sapper, discontentment can up your risk of serious health conditions like cancer and heart disease and knock 12 years off your life, say researchers at State University of New York Upstate Medical Center.

Most Americans are only consuming about two servings of fruits and veggies daily, a shortfall that’s sickening up to 400,000 Americans annually, the Centers for Disease Control and Prevention reports.

Not Enough Exercise

A new report reveals only 5 percent of Americans get regular, vigorous exercise. Dozens of studies now show that lack of exercise more than doubles the risk of obesity, diabetes and heart disease.
