Deep breathing
Deep breathing has been studied in 1 paper since 2024: 1 trial in people. The newest paper, Nov 30, 2024: “Immediate effects of structured and natural deep breathing on heart rate variability and blood pressure in community-dwelling older adults”.

“Both groups showed significant increases during DB in SDNN (p < 0.001), RMSSD (p = 0.021), LF power (p < 0.001), LFnu (p < 0.001), TP (p < 0.001), and LF/HF ratio (p < 0.001).”
None of its findings points the other way.

What did studies of Deep breathing find?
4Studies of Deep breathing measured 4 outcomes; the most studied are blood pressure (1 study), HF power (1) and HFnu (1).
Blood pressure

1 study
Blood pressure
no changein humans1
Deep breathing has no effect on blood pressure in humans.
“BP remained stable throughout the protocol, with no significant changes in either systolic or diastolic BP across time points or between groups.”

Deep breathing decreases HFnu in humans (p < 0.001).
“HFnu decreased significantly during DB (p < 0.001) with no group differences.”

Deep breathing increases SDNN in humans (p < 0.001).
“Both groups showed significant increases during DB in SDNN (p < 0.001), RMSSD (p = 0.021), LF power (p < 0.001), LFnu (p < 0.001), TP (p < 0.001), and LF/HF ratio (p < 0.001).”
