Key result
Manipulating time perception with a distorted timer altered total breath-holding duration, correlating with perceived rather than actual time, driven by changes in the physiological breaking point.
Why the study?
Prior work showed psychological factors can influence breath holding, motivating an examination of how manipulating time perception impacts the physiological response to prolonged voluntary breath holding.
Does manipulating the perception of time affect voluntary breath-holding duration?
Does manipulating the perception of time affect voluntary breath-holding duration?
Unconscious psychological factors and cognitive processes, such as time perception, can significantly influence fundamental physiological processes like breath-holding duration.

Perceived time shapes breath-hold limits; hypothesis-generating for perceptual factors in apnea or autonomic testing.
Vigran et al. (2019) studied this question. Distorted timer (time moving up to 40% faster or slower) vs. Real time was evaluated on Total breath-holding duration and onset of involuntary breathing movements. Manipulating time perception with a distorted timer altered total breath-holding duration, correlating with perceived rather than actual time, driven by changes in the physiological breaking point.
