No. 8: Relax and Learn to Manage Stress
Your life is more zoo than zen -- you rarely get the chance to relax -- and just thinking about making time to meditate is stressful. But studies show that 90 percent of all illnesses, both mental and physical, are related to stress, Horner says. Constant tension elevates the stress hormone cortisol. Anything you do to dampen that physiological response can help your health.

Secrets to success: Chill out in chunks, grabbing a bit of focused relaxation when you can. Research shows that people who meditate for just 20 minutes twice a day are half as likely to be admitted to a hospital, says Horner, who practices Transcendental Meditation. But if om is not where your heart is, hit the gym instead of the ashram. Scientifically, exercise has been shown to reduce levels of stress hormones, says Goldberg, who also suggests reading or listening to music as alternative forms of downtime, since any activity that relaxes you counts as a stress reducer.

If all else fails, consider Horner's favorite stress-reducing supplement: holy basil (available at health-food stores). "This herb is a great example of an adaptogen, which help your body cope with stress and manage cortisol levels," says Horner. One caveat: Holy basil is not recommended for women who are pregnant or trying to conceive.

No. 9: Drink More Water
No caffeine, no bubbles, no fun! But staying hydrated is the best way to flush out toxins, ease digestion, maintain energy, and promote good brain function and all-around health.

Secrets to success: Let vanity motivate you, and think of water as a beauty-boosting beverage. "If a client wants to feel less bloated and leaner, I immediately get her off all soda and juice," Borden says. She allows for only one cup of coffee in the morning: Too much caffeine jacks up your body and confuses your hunger signals, she says, and diet sodas with sugar substitutes stimulate a craving for sweetness.

When you're thirsty, the only liquids you should drink are water or herbal tea, she says, because anything caffeinated is a diuretic. Instead, try to drink 100 ounces of water a day. Borden suggests filling a 32-ounce container and keeping track of how often you have to refill it. Once you've drained it three times, you've (almost) hit your target. One caveat: "I tell people to finish before 4 p.m. so they're not up all night peeing," Borden says. Aim to empty the first bottle by 10 a.m., the next by 1 p.m., and the last by late afternoon. If regular water bores you, add a slice of lemon or cucumber to your glass (just like at the spa!), or try a flavored, calorie-free water, such as Dasani Plus.
