In this video, you'll learn:

- The specific role magnesium plays in sleep — enhancing GABA activity — and why that role has a natural ceiling

- What 2025 and 2023 research tells us about who gets lasting benefit from magnesium and who doesn't

- How to evaluate your magnesium intake to determine whether supplementation is addressing an actual deficiency

- Three steps to identify which sleep patterns magnesium helped and which ones require a different approach

- Why your bedtime stack — magnesium, glycine, L-theanine, tart cherry — may not be reaching the physiology waking you up─────────────────────────About Kat Fu, M.S., M.S.Dual master's degrees in Engineering and Biomechanics.

There's a protective reflex in your esophagus that can pull you out of deep sleep — and many people who experience it never feel heartburn. The connection between what happens in your gut after dinner and that 3AM wake-up window is one of the least recognized patterns in adult sleep. In this video, I'll walk through the mechanism and four evening adjustments that can reduce it.🔍 Why do you wake at 3AM?

Alcohol makes you fall asleep faster and can even increase deep sleep in the first half of the night. But what happens in the second half tells a different story — and it involves your heart rate, your blood sugar, and your REM sleep. This video walks through the three mechanisms and gives you four ways to start addressing them this week.

In this video, you'll learn:- How GABA enhancement from alcohol produces the feeling of deeper early sleep — and why that comes at a cost

- The autonomic imbalance alcohol creates: elevated heart rate, reduced heart rate variability, and impaired cardiovascular braking during sleep

- How alcohol can suppress overnight glucose production — triggering adrenaline and cortisol that wake you up in a wired, activated state

- Why REM sleep gets delayed and reduced, even at doses as low as 1–2 drinks

- Four strategies for reducing alcohol's sleep impact — including dose tapering, earlier timing, and ritual substitution
