Key result
24-hour total sleep deprivation increased muscle sympathetic nerve activity burst frequency in postmenopausal women but not in older men (condition × sex interaction, P=0.032).
Why the study?
Because postmenopausal women are among the highest risk for hypertension, this study compared muscle sympathetic neural activity responses to total sleep deprivation in older men and women.

Does 24-hour total sleep deprivation alter muscle sympathetic neural activity in older adults?
p-value: p=0.032
Total sleep deprivation elicits sympathoexcitation in postmenopausal women but not age-matched men, providing a potential mechanistic link for the stronger association between sleep deprivation and hypertension in women.
No takes yet. Share an insight, caveat, or question.
May indicate sex-specific sympathetic responses to sleep loss; hypothesis-generating and should not yet change practice.
Carter et al. (2019) conducted an RCT in Sleep deprivation (n=27). Total sleep deprivation (TSD) vs. Normal sleep was evaluated on Muscle sympathetic neural activity (MSNA) (p=0.032). 24-hour total sleep deprivation increased muscle sympathetic nerve activity burst frequency in postmenopausal women but not in older men (condition × sex interaction, P=0.032).
