Why nights shifts mess with your brain, how astronauts will cope with the time difference on Mars, and the power of frozen grapes when you need a boost.

Join medical students Laura, Ryhan, Declan, and newly qualified doctor Chidera as we figure out how to survive the night shift. Featuring a guest interview with NASA researcher Erin, leader of the Fatigue Countermeasures Group.

As a student, you may work late but (in the UK) it is unlikely you stay in hospital overnight unless you expressly seek out to do so. So how do you adjust and prepare for night shifts as a new doc?
