adenosine build up and practicing yoga nidra
I'm a regular/daily yoga Nidra practitioner. I know that Andrew practices Yoga Nidra daily. Now that I understand how adenosine builds up in our brain to induce sleep at the end of the day I am concerned that practicing Yoga Nidra in the afternoon would lower the levels of adenosine making falling asleep later in the day more difficult. I suffer from insomnia and although Yoga Nidra helps me get recharged I don't want it to interfere with my sleep.
Impacts of fat soluble vitamin absorption after gallbladder removal
Hello! I was reading "Grain Brain" recently and Dr. Perlmutter briefly mentioned a correlation between Vitamin A, D, K absorption the gallbladder. I had mine removed in 2008, its been a long journey, but one thing I was never told (or even thought) about was if there was an impact on how our bodies absorb these vitamins. Since they're fat soluble and the gallbladder is responsible for producing bile to breakdown fat, it makes sense there would be some impact. For people who have had a Cholecystectomy, is there something they need to do make sure they are absorbing these vitamins? For instance, I take a Vitamin D supplement (5000 IUs) daily, my blood test shows my levels are above 50 but how do I know I'm not wasting the supplement? Should I also take supplements for A and K? Is there something people without a gallbladder should be aware of? Thank you for all you do!
Zone 3?
We’ve obviously learned the benefits, protocols, etc. of zone 2 cardio but what about zone 3? I notice my heart rate reaching the lower level of zone 3 when on an inclined walk and definitely see zone 3 when jumping rope. Does zone 3 count (or double count) when it comes to reaching our weekly zone 2 goal? Is there a weekly limit to be aware of? Do we even need to consider zone 3 whatsoever?
