This episode of WTS* is brought to you by– a question my sister asked me: “Why don’t you drink while you're in school?”

In Ep. II I try to cover common questions and topics about alcohol (below), do a little bit of myth busting, and of course, share a FSF (fun shit fact).

  • What is alcohol?
  • How is alcohol metabolized?
  • Why do I feel like shit* when I have a hanger?
  • Why do I always have to pee?
  • Should I eat while drinking or not?
  • Why and how does alcohol affect memory?

Pobody's Nerfect: Today’s Corrections

At 00:29:30

Correction about aldosterone, I said it was made in the brain, that is incorrect. Aldoesterone is a hormone that participates in fluid retention system but it is made in and released from the adrenal gland (the little triangle lumps that sit on top of your kidneys), it then circulates in the blood and when your kidneys bind this hormone, aldosterone in combination with two other hormones are a signal to retain fluid. But this is not the hormone that alcohol suppresses– alcohol actually suppresses the production of the hormone called vasopressin (or ADH) which is released from your brain. And this is what makes is so you have to urinate constantly.

The full mechanism for blood pressure and fluid retention is below (if you care to know).

Kidney senses low BP/Na+ levels and secretes renin into blood —> (angiotensinogen secreted regularly by liver) —> renin cleaves and coverts angiotensinogen —> angiotensin I —> lung releases ACE —> coverts angiotensin I —> AngII (now biologically active) —> AngII stimulates adrenal cortex to synthesize and secrete mineralocorticoid aldosterone —> AngII + aldosterone —> ↑Na+ retention/↓K+ retention in the kidneys —> AngII —> goes to brain and hypothalmus synthesizes ADH —> pituitary gland secretes ADH (vasopressin) —> AngII + aldosterone + ADH —> ↑H2O Retention + global vasoconstriction

I mention a study that I thought was conducted in the 1960-1970s the study was actually published in 1989 (citation above)

The audio sudden swaps, one of my microphones stopped recording but the other kept going to I had to swap audio files, hopefully I’ll stop running into hiccups.

I say that it was 20% recall (compared to the original recall test done the same day of learning) of the group that drinks alcohol on day 1, the amount of information lost as reported in the study was actually 50%, basically they were only able to recall half as much as they did on the day they learned, and those that drink on night 3 instead were only able to recall 40% as well as day 1 recall.
