A health and science expert talks about how stress affects the brain

Watch this TED Talk about chronic stress – how it can affect our brain size, structure and function. It may even be passed down through our genes.

Cortisol, the stress hormone, prepares the body for instant action, which is a good thing in certain instances. However, high cortisol levels, if left unchecked over time, can have serious consequences.

Stress and cortisol affect the systems that regulate decision-making, judgment and social interactions. It may make it harder to learn, concentrate and remember, and can set the stage for more serious mental problems, such as depression or Alzheimer’s disease.

Fortunately, there are things we can do to take charge of stress, including exercise, nutrition and meditation.
