Andrew Huberman on alcohol & health
Huberman treats alcohol as a toxin: intoxication is acetaldehyde poisoning neural circuits, and even one or two drinks a day is linked to cortical thinning, raised baseline cortisol, more impulsive behavior and higher breast-cancer risk. He says the brain changes are largely reversible after two to six months of abstinence, rejects resveratrol and similar arguments for drinking, and concludes from the literature that zero alcohol is better for health than low-to-moderate drinking.

“You want this peak in cortisol as high as possible in the first 60 minutes of your day. Everyone thinks you want low cortisol, but here's the deal. High cortisol in the early part of your day is what provides for elevated mood, focus, attention, your ability to learn. It's also what establishes low cortisol in the afternoon and at night which is a requirement for falling and staying asleep.”

“how much dopamine is in our system at any one time compared to how much dopamine was in our system a few minutes ago, that dictates your so-called quality of life and your desire to pursue things. This is important. Your experience of life and your level of motivation and drive depends on how much dopamine you have relative to your recent experience. This is why when you repeatedly engage in something that you enjoy, your threshold for enjoyment goes up and up and up.”

“What is cortisol? We I should have mentioned this earlier. What is cortisol? Is it a stress hormone? No. It's a hormone that's released during stress. But cortisol's job is not to deal with stress. Cortisol's job is to mobilize energy in the body. When cortisol goes up, glucose is mobilized and other fuels, too.”

“When we decide to focus what the brain really does is it switches on a set of circuits then all the frontal cortex and nucleus basalis and some others and it's trying to understand duration, how long something's gonna last, path, what's gonna happen, and outcome, what ultimately is gonna happen. So duration, path and outcome. You know, the events of early 2020 are a good example of this. One of the reasons why it's so exhausting to be alive in 2020, is because we are now having to pay attention to duration, path and outcome. How long is this thing gonna last? When are, you know, when are they gonna open up all businesses? Did I touch that door handle? Does it matter? You know, who are the experts? Are there any experts? You know, there are a lot of questions whereas normally, we can just move through life without having to do all that analysis.”
