The harmful effects of stress on your health are not inevitable, according to health psychologist Kelly McGonigal, PhD. McGonigal, a well-respected Stanford University lecturer explains “How to Make Stress Your Friend” in this 14-minute TED Talk with nearly 10.5 million views.

McGonigal, who has authored several books, explains that research reveals the opposite of the long-held belief that stress was harmful to health. She explains that how one thinks and how one acts can transform the experience of stress.
