2. Take a whiff of lavender. In 2008 Japanese researchers reported that the aroma reduces stress levels in people forced to do tough math problems. Keep a small bottle of lavender oil or lotion in your purse for when you're feeling overwhelmed.
3. Sip black tea. University College London scientists found that black-tea drinkers had lower levels of the stress hormone cortisol after a stressful event than those who consumed other hot beverages.
4. Get some distance. When you're slammed with something really stressful—a huge work deadline, an unexpected visit from the in-laws—don't panic. Instead, pretend you've been asked to advise a friend or family member in need, and think through the problem systematically, says Carol J. Scott, MD. "When women distance themselves slightly from stressors, they make excellent problem solvers, in part because of their unique mixture of creative, intuitive, and analytical thinking skills."
