‘Sleep is an investment in the energy you need to be effective tomorrow’ - Tom Rath
The title of this blog post is taken from the name of a very popular TED Talk by brain scientist and sleep expert Matthew Walker. So popular in fact, that at the time of writing it had almost 17 million views! Its popularity - and that of his many other TED Talks on subjects ranging from the relationship between sleep and emotions, sleep and memory, sleep and hunger and many more - is indicative of the wider concerns about and problems with sleep affecting modern-day western society.
