 So, I've had the pleasure of working with two noted sleep experts, one from Los Angeles and one from Harvard. And flight attendants are some of the biggest sufferers from sleep deprivation because we now know that not only does your circadian rhythm change with time zones, but the bugs that live in your gut have their own circadian rhythm and we're beginning to understand that that circadian rhythm may be more important than just time zones. So here's a few tricks I travel a lot internationally and throughout the United States. So get yourself a pair of blue blocking sunglasses and wear them whenever possible, particularly when changing time zones. Blue light is what actually keeps us awake. I like timed release melatonin. Get yourself three, five milligrams, but by the timed release. Really helps reset your clock. You don't need a whole big dose. There's other supplements that are perfectly useful like GABA, like Kavakava, like L-theanine. And it's useful trying those. The other thing that I think is a great trick is carrying along vital reds. Vital reds has a really important probiotic that survives digestion and I just fertilize when I get to my new spot, new probiotics and often time that's all it needs to reset your clock. Blue blocking sunglasses, a little bit of timed release melatonin and some vital reds. Let me know how it goes. Thanks for watching.
