Sleep is one of the most important, yet least understood aspects of our lives.
For the longest time, science did not have the answer to why we sleep or what good it serves.
Over the last 20 years, a lot of scientific discoveries have shed light on this fundamental aspect of our lives.
Sleep expert Matthew Walker, in his book Why We Sleep, gives us a fresh understanding of why we need sleep and dreaming.
Sleep enriches our ability to learn and make logical decisions. It recalibrates our emotions, balances our immune system, fine-tunes our metabolism and regulates our appetite.
Matthew answers questions like how caffeine and alcohol affect sleep, what really happens in REM sleep, why our sleeping patterns change across a lifetime and many other intriguing questions.
