Here are eight surprising ways to invoke it — and in some cases, cut your cortisol levels almost in half.
Cut cortisol 20 percent
Say "Om." Subjects who practiced Buddhist meditation significantly decreased both cortisol and blood pressure in a six-week Thai study. Similarly, participants who meditated daily for four months decreased the hormone by an average of 20 percent in a study at Maharishi University, while levels in the nonmeditating control group actually went up slightly.
Cut cortisol elevation 66 percent
Make a great iPod mix. Music can have a calming effect on the brain, especially while you're facing down a major stressor. When doctors at Japan's Osaka Medical Center played tunes for a group of patients undergoing colonoscopies, the patients' cortisol levels rose less than those of others who underwent the same procedure in a quiet room.
Cut cortisol 50 percent
Hit the sack early — or take a nap. The recommended eight hours of nightly shut-eye allows your body enough time to recover from the day's stresses, study found. When you fall short of the mark, take a nap the next day — Pennsylvania State University researchers found that a midday snooze cut cortisol levels in subjects who'd lost sleep the previous night.
Cut cortisol 47 percent
Sip some black tea. When volunteers at University College London were given a stressful task, the cortisol levels of those who were regular black-tea drinkers fell by 47 percent within an hour of completing the assignment, while others who drank fake tea experienced only a 27 percent drop.
Cut cortisol 39 percent
Hang out with a funny friend. The pal who keeps you in stitches can do more than distract you from your problems — her very presence may help temper your hormonal stress response. Simply anticipating laughter is enough to reduce cortisol levels by nearly half, according to researchers at Loma Linda University.
Cut cortisol 31 percent
Schedule a massage. A little pampering can rub your stress levels the right way. After several weeks of massage therapy, subjects' cortisol levels decreased by nearly one-third, on average, according to studies at the University of Miami School of Medicine and elsewhere.
Cut cortisol 25 percent
Do something spiritual. Religious ritual fortifies many people against everyday pressures, and it can also lower cortisol secretion, report University of Mississippi researchers. Churchgoing study subjects had lower levels of the stress hormone, on average, than those who did not attend services at all.
Cut cortisol 12 percent to 16 percent
Chew a piece of gum. Next time you feel frazzled, try popping a stick of gum into your mouth to instantly defuse tension, suggest new findings from Northumbria University in the United Kingdom. While under moderate stress, gum chewers had salivary cortisol levels
that were 12 percent lower than nonchewers and also reported greater alertness than their gum-deprived counterparts.
