Slow and deep breathing improves heart rate variability (HRV) and can help you make better decisions in business, according to studies from Belgian researchers.
Slow and deep breathing can increase vagal nerve activity and, in doing so, increase heart rate variability. The research was carried out on the effects of breathing patterns on HRV (Study 1) and on decision-making in business under stress (Study 2).
In Study 1, a group of 30 healthy adults used either a symmetric breathing pattern (equal ratio of inhaling/exhaling) or a skewed pattern (exhalation longer than inhalation) or watched an emotionally neutral film. Those using the breathing patterns showed visible improvement, while those viewing the neutral video had no change.
“Both types of breathing patterns significantly increased time and frequency domain HRV parameters, while viewing the film did not,” read the study.
For Study 2, a randomised test group of 56 business students carried out skewed breathing patterns for two minutes before completing a 30-minute, multiple-choice, business decision-making task. The control group simply waited for two minutes before starting the same job.
“Stress levels were self-reported before and after the task. While controls reported elevated stress levels, those in the experimental group did not. Importantly, participants in the experimental group provided a significantly higher percentage of correct answers than controls,” according to the study.

Deep slow breathing can increase vagal nerve activity, indexed by heart rate variability (HRV). HRV is also associated with better decision-making. This research examined the effects of two breathing patterns on HRV (Study 1) and on stress and decision-making performance (Study 2). In Study 1, 30 he...
