Описание: What Waking Up With Numb Hands REALLY Says About Your Heart | Doctor Harron

Millions of people wake up at 3 AM with numb hands and are told it's carpal tunnel or sleep position. Most of them are never asked the right question — and the right question points directly to the heart.

In this video:
How nocturnal cardiac output drops create peripheral vasoconstriction — and why the 2–4 AM window is the most dangerous
What low Heart Rate Variability (HRV) during sleep signals about cardiovascular risk — including a 45% increased risk finding from the European Heart Journal
What nocturnal AFib is, why a standard 12-second ECG will never detect it, and how it connects hand numbness to stroke risk
5 actionable steps to take now: document the pattern, request cardiovascular evaluation, track HRV, screen for sleep apnea and blood sugar, and don't wait for pain
