Deconstructing the "Sleepy Girl Mocktail", Matt separates digital hype from rigorous sleep science. He delineates that tart cherry juice works not through trace melatonin, but as an anti-inflammatory "bodyguard" for tryptophan by inhibiting the enzyme IDO. 

Matt also exposes the fragile "84-minute" claim, which originated from a pilot study of just eight people. Conceding that magnesium and prebiotics offer modest nudges, our host stresses that the true efficacy is behavioral, replacing a nightcap with a calming ritual. Matt concludes that no elixir outshines biological fundamentals like regularity, cool temperatures, and light management.
