The Claim
Partial sleep deprivation does not change morning cortisol levels, even though it increases NF-κB activation, indicating that the inflammatory response triggered by partial sleep deprivation is not mediated by alterations in cortisol.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Skipping a few hours of sleep doesn't raise your stress hormone (cortisol) in the morning, even though it still turns on your body's inflammation system—so your inflammation isn't caused by that stress hormone.
See the scientific wording
Partial sleep deprivation does not alter cortisol levels in the morning, despite increasing NF-κB activation, suggesting that the inflammatory response is not mediated by changes in this key stress hormone.
What the research says
1 studyStudy: Sleep loss activates cellular inflammatory signaling.
When people don’t get enough sleep, their body gets more inflamed, but their stress hormone (cortisol) doesn’t go up in the morning — meaning the inflammation happens for another reason, not because of stress hormones.
