How stress affects your brain | Madhumita Murgia

Stress isn't always a bad thing; it can be handy for a burst of extra energy and focus, like when you're playing a competitive sport or have to speak in public. But when it's continuous, it actually begins to change your brain. Madhumita Murgia shows how chronic stress can affect brain size, its structure, and how it functions, right down to the level of your genes. [Directed by Andrew Zimbelman, narrated by Addison Anderson, music by Josh Smoak].
