If the Dow just closed after a dismal day of trading and a tightening sensation is beginning to spread through your chest, stop and try this exercise:
Instead of focusing on the money you've already lost or obsessing over future losses, try zeroing in on the present moment. Let go of distractions like a looming bill or the record unemployment rate and concentrate on your breath. Take in all the air you can, pause and then release.
"It's actually totally boring concentrating on your breath," says Dr. Michael J. Baime, director of the Penn Program for Stress Management at the University of Pennsylvania Health System. "Lifting a barbell is totally boring too, but it's exercising a muscle." After 10 repetitions, he says, you should start to feel some degree of calm.
