In this \u201cAsk Me Anything\u201d (AMA) episode, Peter and Bob first answer a variety of questions related to heart rate variability (HRV): what it means, why it matters, and how to measure, interpret, and potentially elevate it. Next, they dive deep into the topic of alcohol, beginning with a discussion on the negative impact that it can have on sleep. They then break down the confusing body of literature suggesting potential health benefits to moderate levels of drinking compared to complete abstinence and point out the limitations of these studies. Finally, they conclude by analyzing data on the impact of moderate and heavy drinking on the liver and on risk for Alzheimer\u2019s disease and dementia.
