Are yoga pants and high heels hurting your health?

Is your closet filled with chic threads and killer shoes? Beware: Your favorite wooly sweaters, stylish yoga pants, and high heels could be health hazards. Here's why -- and what you should wear instead.

1. Comfy Yoga Pants

The trap: Yoga pants are the fashion diva's answer to sweats. But all that stretch lets you ignore an expanding waistline -- bad for your heart and your self-esteem.

The impact: A thick middle -- over 35 inches for women, 40 inches for men -- boosts your diabetes risk up to 10 times, even if you're not overweight! Your odds for high blood pressure and high cholesterol rise, too. The cause: visceral fat around your mid-section. Its gooey globules inflame your liver, blood vessels, immune system, and more.

Swap 'em for: Pants that button at the waist. When they feel snug, you know it's time to exercise more and eat less. (Save your Lululemons for yoga class.)

2. Cozy-Chic Wool Sweaters

The trap: Wool acts like Velcro to attract all kinds of stuff, including allergens like cat dander.

The impact: In one study, cat-dander levels were 11 times higher and dust mite levels 10 times higher on wool sweaters than on bare skin. No wonder your sweater could trigger miserable sneezing, a dripping nose, and teary eyes.

Swap 'em for: Cotton sweaters. If your allergies are super serious, just wear cotton T-shirts (layer them if it's cold). They pick up the fewest allergens.

3. Four-Inch Heels and Perilous PlatformsThe trap: Torturing your tootsies by jamming them into sky-high shoes sets you up for serious foot pain.

The impact: High heels boost your risk for foot pain by a whopping 67%. How? Wearing heels that are 2 inches or higher every day shortens calf muscles and thickens your Achilles tendons, making the world's easiest exercise -- walking -- difficult. Chunky platforms are easier on your feet, but because you can't feel the ground under you very well, tripping on uneven pavement is a daily risk.

Swap 'em for: Kitten heels and ballet flats. They're stylish (flats are back, big-time) and unlikely to send you careening onto the sidewalk.
