The Claim

A two-hour mid-afternoon nap following one night of total sleep deprivation does not reverse or significantly influence daytime leptin elevation, adiponectin changes, or subjective hunger levels in young healthy adults, indicating that brief recovery sleep is insufficient to restore normal endocrine and appetite regulation.

Cause and effect
1 study reviewed
In plain English

Taking a two-hour nap in the afternoon after staying up all night doesn't fix the hormone changes or hunger spikes caused by lack of sleep. Even a short daytime nap isn't enough to bring your body's stress and appetite hormones back to normal.

See the scientific wording

A two-hour mid-afternoon nap following one night of total sleep loss does not reverse or significantly influence the subsequent elevation of daytime leptin, changes in adiponectin, or subjective hunger levels in young healthy adults. Short daytime sleep does not mitigate the acute endocrine and appetite responses to total sleep deprivation, suggesting that brief recovery sleep is insufficient to restore normal hormonal regulation.

What the research says

1 study
  1. Study: Leptin and hunger levels in young healthy adults after one night of sleep loss

    Taking a two-hour nap after a night of no sleep does not fix the hunger hormones or appetite changes caused by the lack of sleep. A short nap simply isn't enough to reset your body's stress and hunger signals.
