Key result
Total sleep deprivation for 24 hours augmented heart rate responses during mental stress and cold pressor tests (P≤0.05) but did not alter MAP, MSNA, or forearm vascular responses.
Why the study?
Does 24-h total sleep deprivation alter cardiovascular reactivity to acute stressors in young, healthy subjects?
RCT (n=28)

Does 24-h total sleep deprivation alter cardiovascular reactivity to acute stressors in young, healthy subjects?
p-value: p=≤0.05
Total sleep deprivation augments tachycardia responses to acute stressors, providing insight into the link between sleep deprivation and cardiovascular risk.

Augments stress-induced tachycardia in healthy adults; extends causal RCT evidence linking sleep loss to cardiovascular reactivity.
Yang et al. (2012) conducted an RCT in healthy subjects (n=28). Total sleep deprivation vs. Normal sleep was evaluated on Cardiovascular reactivity (MAP, HR, MSNA, FVC) to mental stress and cold pressor test (p=≤0.05). Total sleep deprivation for 24 hours augmented heart rate responses during mental stress and cold pressor tests (P≤0.05) but did not alter MAP, MSNA, or forearm vascular responses.
