The Claim
Total sleep deprivation for 38 hours significantly increases systolic and diastolic blood pressure, heart rate, and interleukin-6 levels while reducing endothelial-dependent and -independent cutaneous vascular conductance in healthy adults.
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.
Thirty-eight hours without sleep raises blood pressure, heart rate, and interleukin-6 levels, and lowers skin blood flow responses in healthy adults.
See the scientific wording
Total sleep deprivation for 38 hours significantly increases systolic and diastolic blood pressure, heart rate, and interleukin-6 levels while reducing endothelial-dependent and -independent cutaneous vascular conductance in healthy adults, confirming its role as a potent physiological stressor.
Staying awake for 38 hours without sleep causes the brain to overstimulate the nervous system that raises heart rate and blood pressure. This stress response blocks natural signals that relax blood vessels, reduces the production of a key molecule that keeps vessels open, and triggers immune cells to release a powerful inflammatory chemical. Together, these changes make blood vessels stiffer, raise blood pressure, increase heart rate, and flood the body with inflammation.
What the research says
1 studyBeing awake for 38 hours without sleep made healthy people’s blood pressure and heart rate go up, increased a marker of body inflammation, and made their blood vessels work worse—all signs their bodies were under serious stress. The study proved this even without caffeine.
