Sex differences in altitude HRV merit monitoring consideration; hypothesis-generating and should not yet change practice.
Does high altitude exposure alter heart rate variability differently in men versus women, and does it predict acute mountain sickness in healthy adults?
High altitude exposure significantly reduces heart rate variability, with men maintaining higher variability than women, though these autonomic changes do not predict the development of acute mountain sickness.
Boos et al. (2017) studied this question.
