Ever wondered how much caffeine is too much? Or whether you’d feel better off if you took an afternoon nap? And with the rise in ‘day raving’ we’ll be looking at whether it’s better for your health to have your night out at 2pm rather than 2am.

We’ll learn about the amount of caffeine in different drinks, looking at what it does to the body in the short-term and finding out more about what effects it can have when it comes to things like dementia and cardiovascular disease.

Then we’ll be following a strict scientifically-approved napping schedule and hearing what impact those bonus sleep sessions can have on brain function – while catching 40 winks in some unusual locations.

After that, we’ll take all that energy and party the afternoon (and early evening) away at a daytime rave to find out if that is better for our bodies than pulling an all-nighter.

Along the way we’ll be joined by people who know way more about these things than us, from a Spanish sleep whizz in Manchester to a body boffin in Barry Island.
