Key result
Five nights of partial sleep deprivation significantly increased sympathetic activity and reduced maximum endothelial dependent venodilatation (41% vs 100%; P<0.05) compared to control sleep.
Why the study?
Does partial sleep deprivation increase sympathetic activity and impair venous endothelial function in healthy volunteers?
RCT (n=13)

Does partial sleep deprivation increase sympathetic activity and impair venous endothelial function in healthy volunteers?
p-value: p=<0.05
Partial sleep deprivation over 5 nights significantly increases sympathetic activity and impairs venous endothelial function in healthy young men, providing a potential mechanism for the epidemiological association between short sleep and increased cardiovascular risk.

Supports sleep optimization for vascular health; extends RCT evidence linking short sleep to endothelial impairment.
Dettoni et al. (2012) conducted an RCT in Healthy volunteers (n=13). Partial sleep deprivation (<5 h) vs. Control sleep (>7 h) was evaluated on Heart rate variability, blood pressure variability, serum norepinephrine, and venous endothelial function (p=<0.05). Five nights of partial sleep deprivation significantly increased sympathetic activity and reduced maximum endothelial dependent venodilatation (41% vs 100%; P<0.05) compared to control sleep.
