The science

That uneasy, jittery morning after drinking has a name and a mechanism. Here's why alcohol calms you at night and rebounds into anxiety the next day — and what helps.

Your body clears roughly one standard drink an hour, and nothing speeds it up. Here's how alcohol is metabolized, how long tests can detect it, and what changes the rate.

A drink helps you fall asleep faster, then quietly wrecks the second half of the night — less REM, more waking. Here's what alcohol does to your sleep, and how to limit it.

Alcohol is nearly as calorie-dense as fat, carries no nutrition, and nudges you to eat more — while your body burns it before fat. Here's the real link between drinking and weight.

The advice has shifted: health authorities now say less is better and no amount is risk-free. Here's what 'moderate drinking' meant, what changed, and how to think about it.

Better sleep, a calmer liver, lower blood pressure, fewer empty calories — the real, sourced benefits of drinking less, and roughly how soon they show up.

Alcohol carries about 7 calories per gram — roughly 98 calories per US standard drink before mixers and carbs. Here's how beer, wine, and spirits compare.

A 16 oz pour of a 7% IPA is about 1.9 US standard drinks — nearly two. Here's the math, by can and by pint, and why hazy IPAs add up fast.

A US standard drink is a fixed amount of pure alcohol — 0.6 fl oz (14 g), about one 12 oz beer, a 5 oz glass of wine, or a 1.5 oz shot. Here's how to count any drink accurately.
