He discovers why cutting our sleep short can be linked to a host of illnesses, including serious diseases like Alzheimer’s. Putting his own sleeping brain and body to the test, Michael signs up for two revealing experiments: wearing a new device that maps his sleep and allows scientists to see how it measures up to an ideal night, and taking part in a sleep deprivation experiment, where he is confronted by the fact that just one sleepless night impacts his cognitive performance. Revealing the very latest science breakthroughs and packed with personal anecdotes, this programme is a useful guide to anyone looking for tips and insights on how to get the benefits from learning how to sleep well.
