According to World Sleep Day, “Sleep problems constitute a global epidemic that threatens health and quality of life for up to 45% of the world’s population.” The matter of sleep is so critical that in this episode, Neuroscience Professor and sleep expert, Dr. Matthew Walker, exposes the severity of sleep deprivation as so serious that the Guiness Book of World Records no longer allows record setting attempts for sleep deprivation but allows far more extremes. There is a need to highly value sleep and learn tips to improve your sleep health and be more productive in your time awake.

0:00.0	From an evolutionary perspective, sleep is the most idiotic of all behaviors.
0:07.8	When you think about it, because firstly, when you're asleep, you're not finding a mate,
0:12.0	you're not reproducing, you're not caring for your young, you're not foraging for food,
0:17.2	and were still, you're vulnerable to predation.
0:20.8	Now, on any one of those single grounds, but especially all of them as a collective,
0:25.9	sleep should have been strongly selected against.
0:35.8	Hey everybody, welcome to another episode of Health Theory. I am here with somebody that's
0:39.7	going to blow your mind. His name is Matthew Walker. Matthew, welcome to the show.
0:45.3	It's a delight to be here, Tom. Thank you for having me.
0:48.1	Dude, super excited. I was telling you before we started recording that you wrote a book called
0:52.2	Why We Sleep? I'm always worried when I'm bringing somebody on that's covering a subject that
0:57.5	I've talked about before if they're going to hit it in a new way. I love your book. You come at

1:23.7	Records will not let people try to set records for sleep deprivation. Walk us through why not.
1:29.7	I think this is a great entry to your world. What we know is that a lack of sleep will
1:37.9	impact just about every major physiological system in your body and almost every operation of
1:43.6	your mind. For example, if I were to take you and limit you to just four hours of sleep for one
1:49.5	single night, there is almost a 70% drop in what we call natural killer cell activity, which are
1:56.9	critical anti-cancer fighting immune cells. That's after one night of four hours of sleep.
