The stress hormone, cortisol, is public health enemy number one. Scientists have known for years that elevated cortisol levels: interfere with learning and memory, lower immune function and bone density, increase weight gain, blood pressure, cholesterol, heart disease... The list goes on and on.

This week, two separate studies were published in Science linking elevated cortisol levels as a potential trigger for mental illness and decreased resilience — especially in adolescence.
