According to traditional Chinese medicine, maintaining your body's vital energy, or qi (pronounced "chee"), will ward off low energy and sickness. Here's how.

1. Eat organic. Pesticides burden the liver and stagnate qi. Also avoid sugar, which has a similar effect.
2. Work out. Exercise is the best way to get your qi flowing. Practicing tai chi and qigong — even for just five or ten minutes — stimulates body, mind, and breath. Although any kind of exercise will do, don't exhaust yourself. Pushing past your limits may deplete your qi.
3. Strive for emotional balance. Keeping emotions bottled up stagnates the qi, while expressing them frees it. Talk with friends, write in a journal, and pause for a few deep, tension-relieving breaths whenever you feel rushed or scattered. And reduce anxiety-causing negativity by recognizing at least one thing you're grateful for every day.
