Every year, somewhere around 4 p.m. on the fourth Thursday of November, an entire country slumps sideways on the couch and blames the bird.
“It’s the tryptophan,” someone mumbles, eyes half closed, a fork still in one hand. Everyone nods. Case closed.
Except the case isn’t closed. The turkey has been taking the fall for decades, and the real story is more interesting. So before you loosen your belt this year, here are eight fun facts about the famous turkey coma: what’s myth, what’s real, and what you can do about it.
1. Turkey isn’t special when it comes to tryptophan
Tryptophan is an amino acid your body uses to make serotonin and, later, melatonin. That part’s true. The problem is that turkey doesn’t have an unusual amount of it. Texas Health Resources notes that turkey has about the same tryptophan as chicken or beef. Some cheeses and nuts have more.
Nobody blames a grilled chicken sandwich for their 2 p.m. nap. The turkey just has better PR.
2. Tryptophan has to fight its way into your brain
Even the tryptophan you do eat doesn’t walk straight into your brain. It competes with a crowd of other amino acids for the same way in. Turkey, being protein, is full of those competitors. So the tryptophan in a slice of turkey mostly ends up waiting in line.
Here’s the twist. The usual explanation is that carbohydrates raise insulin, insulin moves some of the competing amino acids into your muscles, and that clears a little room for tryptophan. If that’s right, the stuffing, rolls and pie may do more to make you drowsy than the turkey. The bird has been covering for dessert this whole time.
3. Your body was planning an afternoon dip anyway
That mid-afternoon slump isn’t only about food. In a review of the “post-lunch dip”, sleep researcher Timothy Monk described a real rise in sleepiness in the mid-afternoon that can happen even when people skip lunch and don’t know what time it is. It’s built into the body’s daily rhythm. A big, carb-heavy meal makes it worse.
Most Thanksgiving dinners happen in the middle of the afternoon. You’re scheduling the biggest meal of the year during your body’s built-in nap window, and then acting surprised.
4. Portion size is the real heavyweight
The simplest explanation is the least romantic one: Thanksgiving is a lot of food. A huge meal sends your body into digest mode, and you feel slow while it gets through the backlog. Texas Health points to the sheer amount of food, the refined carbs and the desserts as more likely causes of the slump than any one ingredient.
Their advice is very practical: eat a bit slower, take a smaller first plate (you can always go back), and take a walk after the meal. A loop around the block won’t make you feel virtuous, but it will help.
5. The wine is a double agent
Alcohol makes you feel sleepy, so it seems like it should help. It does, at first. A 2013 review of alcohol and sleep in healthy people found that at all doses, alcohol helps you fall asleep faster and makes the first half of the night more solid. Then it disturbs the second half. It also delays the first REM period of the night, which was the most consistent effect the researchers found.
A 2024 lab study published in Sleep found much the same thing over several nights in a row. Thirty adults slept more deeply early in the night after drinking, then woke up more and slept less soundly later. So the 9 p.m. couch nap feels great. The 3 a.m. stare at the ceiling is the bill arriving.
6. Wild turkeys sleep in trees
A quick break from the science. While you’re asleep on the couch, wild turkeys are sleeping somewhere much more dramatic. At dusk they fly up into trees and roost on branches for the night, safely away from predators on the ground. Yes, turkeys fly. Wild ones do, anyway. The heavy farm-raised birds bred for the dinner table mostly can’t.
So the real turkey goes to sleep high up in a tree, and the people who just ate one fall asleep in a recliner.
7. Ben Franklin didn’t actually want the turkey as the national bird
This is the other big turkey myth. In a 1784 letter to his daughter, Franklin criticized the bald eagle’s “bad moral character” and called the turkey a more respectable bird. People have treated that as a serious proposal ever since. According to Live Science, historians think he was probably joking. He never formally proposed a turkey. His own idea for the Great Seal was a scene from Exodus.
Fun bonus: the eagle was America’s unofficial national bird for a very long time. Congress only made it official in December 2024.
8. The cure for a turkey coma is boring: sleep
The end of November is rough on sleep. Daylight saving time just ended, so it gets dark before dinner. Plus travel, late nights with family, rich food and a few extra drinks. The CDC recommends at least 7 hours a night for most adults, and also lists heavy meals and alcohol close to bedtime as habits that can get in the way.
That leaves the least exciting tips there are, and the ones that work best. Eat the big meal earlier in the day if you can. Leave a few hours between the last plate and bed. Take the walk. Have a glass of water between glasses of wine. Go to bed at about your normal time, even if your cousin wants to start a fourth round of cards.
Where CBD fits (and where it doesn’t)
Let’s be clear: CBD isn’t a sedative, and it won’t undo a third slice of pecan pie. But a lot of people make it part of a calmer evening routine, and the early research is interesting. In a 2019 case series in The Permanente Journal, about two-thirds of the adults studied reported better sleep scores in the first month of taking CBD. Those scores went up and down over time, though, and the study had no control group. The authors said proper controlled trials are needed. In other words: promising, not proven.
If you’d like to try it, our pick is consistency over heroics. A steady daily routine fits CBD better than a one-night fix. Woven Earth’s Daily Full Spectrum Softgels are made for exactly that: one easy, pre-measured habit, and no dropper to fumble with after a big dinner.
The bottom line
The turkey is innocent, or at least no guiltier than a chicken. The real culprits are the size of the meal, the carbs, the wine, the time of day and a calendar that’s already hard on your sleep. Eat what you love. Take the walk. Go easy on the nightcap. And this year, when someone at the table blames the tryptophan, you’ll have eight fun facts ready to go. Just don’t use all eight before pie.
