“the fear here although there are some studies that people have argued this is not the case but the fear is just like testosterone replacement at some point your testes if you're exogenously injecting will just stop producing innate testosterone and once they stop they don't restart the worry is the same with your pineal gland which is going to release melatonin that if you keep exogenously giving your brain vast amounts it says well you're giving it to me so I don't need to produce it anymore and once it stops does it ever restart”
Main Takeaways:
- Concerns exist that prolonged external intake of melatonin might cause the pineal gland to stop producing it naturally.
- This effect is compared to the impact of long-term testosterone replacement therapy on natural testosterone production.

“CBD I think is actually one of the the potential contenders in this category of new emerging Technologies pharmacologically CBD I think is is we still don't have enough data I think the problem with CBD is that it is dose dependent if you look at the data squint your eyes because there's not enough and you make a non-scientific kind of guesstimation anything less than about 25 milligrams seems to actually be wake promoting whereas anything that's about 50 milligrams or more may actually be sleep promoting.”

“by rocking you at this gentle frequency it increased the amount of those deep sleep brain waves and these additional burst of brain waves that ride on top of them like Surfers on the on a wave called sleep spindles and the combination of those two we know are important to hit the save button on new memories for what we call memory consolidation”
Main Takeaways:
- Gentle rocking at specific frequencies can enhance deep sleep brain waves and sleep spindles.
