You’re just one history final away from a relaxing spring break. But you still have so much to study! You decide to follow in the footsteps of many students before you, and pull an all-nighter. So, what happens to your brain when you stay up all night? And does cramming like this actually help you prepare for a test? Anna Rothschild explores how a sleepless night impacts your cognitive function. [Directed by Biljana Labović, narrated by Jack Cutmore-Scott, music by Salil Bhayani, cAMP Studio]. After the talk Shoshana does a dive deep into the effects of sleep deprivation on other aspects of your health -- starting with the heart.
