Stress. It makes your heart pound, your breathing quicken and your forehead sweat. But while stress has been made into a public health enemy, new research suggests that stress may only be bad for you if you believe that to be the case. Health psychologist Kelly McGonigal urges us to see stress as a positive. If you believe that your body is energized and preparing you to take action, your physical stress response changes, with no negative effect on your heart. Watch this TED talk, in which McGonigal reveals a surprising mechanism for stress reduction: reaching out to others.
