The Claim

In adults aged 30–60, chronic sleep restriction, as measured by self-reported habitual sleep, is primarily associated with reduced leptin levels, while acute sleep loss, as measured by polysomnography, is primarily associated with elevated ghrelin levels, suggesting distinct temporal roles for these hormones in sleep-related appetite dysregulation.

How it works
1 study reviewed
In plain English

When adults between 30 and 60 don’t get enough sleep over a long time, their body makes less of a hormone that tells them they’re full; but if they miss a night of sleep, their body makes more of a hormone that makes them feel hungry—so different kinds of sleep loss affect hunger in different ways.

In adults aged 30–60, chronic sleep restriction (measured by self-reported habitual sleep) is primarily associated with reduced leptin, while acute sleep loss (measured by polysomnography) is primarily associated with elevated ghrelin, suggesting distinct temporal roles for these hormones in sleep-related appetite dysregulation.

  1. Study: Short Sleep Duration Is Associated with Reduced Leptin, Elevated Ghrelin, and Increased Body Mass Index

    The study found that people who regularly sleep too little have lower levels of a hormone that tells you you're full (leptin), and when they sleep poorly just one night, they have higher levels of a hormone that makes you hungry (ghrelin)—which is exactly what the claim says.
