  • Here's the problem with magnesium supplementation when it comes to sleep.

  • The first thing to note is that most forms of magnesium don't cross the brain barrier and sleep is produced by your brain.

  • So how can something that doesn't get into your brain affect brain process?

  • All you're doing is creating probably expensive urine.

  • However, there is one form of magnesium that seems to have some evidence in favour of it, which we can speak about, but it doesn't stop there.

  • There's so much new evidence that we have, including this myth of eight hours.

  • I fear about giving melatonin to kids while you're keeping waking up in the middle of the night and the invention of the first new class of sleeping medication that I actually favour.

  • And most people are not aware of it.

  • Okay, let me write this down.

  • Matthew Walker is back and the world-renowned sleep expert and neuroscience professor is sharing brand new research to combat the sleep loss epidemic and help you get the perfect night's sleep.

  • So society, we have struggles with sleep at night due to many reasons, but no one teaches us this stuff.

  • And it's things like, say you go to bed at 11, one night, one AM the next night, then 10, 30 PM the next night.

  • And it's remarkable how many people do this.

  • Studies have shown that you are statistically 49% more likely to prematurely die versus those people who are most regular in terms of going to bed and waking up at the same time.

  • And worse, they had a 57% cardiometabolic disease risk increase.

  • What the?

  • Science really teaches us that there are four pillars of good sleep.

  • And then there's this incredible new study.

  • Just give me 30 seconds of your time.

  • Two things I wanted to say.
