What the research says
1 study reviewedSupporting (1)
Cohort StudyHuman2025
When animals and people don’t sleep, their bodies produce more white blood cells and inflammation chemicals—and this happens the same way in fish, pigs, mice, and humans because of a shared biological switch.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When sleep is lost, immune cells called neutrophils start using sugar faster than normal, producing more lactate. This lactate changes the way genes are read in these cells by attaching to DNA-packaging proteins, which turns on a gene called RORα. RORα then activates another gene that triggers the production of inflammatory chemicals and causes more neutrophils to multiply and move into tissues, raising their numbers in the blood.

Mechanism
1 studyWhen you don’t sleep, your immune cells burn sugar faster, making more lactate. This lactate flips a genetic switch that turns on inflammation genes, causing more immune cells to multiply and flood into tissues, raising their numbers in the blood and releasing inflammatory chemicals.

Sleep deprivation increases metabolic demand in neutrophils, triggering enhanced glycolytic flux
Elevated glycolysis leads to increased intracellular lactate production and accumulation
Lactate serves as a substrate for histone H3K18 lactylation, catalyzed by p300 and inhibited by HDAC3
H3K18 lactylation is enriched at the promoter region of the RORα gene, directly enhancing its transcription
RORα transcription factor activates expression of C/EBPβ and downstream proinflammatory genes (IL-1β, IL-6, TNF-α, CXCL8)
C/EBPβ drives transcription of neutrophil activation and chemotaxis genes, leading to neutrophil proliferation and tissue infiltration
Neutrophil activation results in systemic accumulation, tissue infiltration, and elevated circulating proinflammatory cytokine levels
