AFTER 70: This is What Happens to Your Circulation While You Sleep

You are the one person in your house who has never seen how you sleep. In this video, I walk you through a single night, hour by hour: how your bedroom temperature, noise, and evening fluids affect your sleep, what happens to your blood pressure, whether your sleeping position really matters, why sleep apnea may be the hidden issue behind stubborn blood pressure, and the stroke warning signs to know. You’ll get a three-shift protocol: a one-week night audit, a two-week experiment, and the three questions to ask your doctor.
