Sometimes when I have negative feelings, it seems that a deep breath resets these feelings. Does that really happen? Is there any research on the effect of taking a deep breath on reducing the experience of negative emotions?

Its a ritual and a coping mech. yeah its psychologically identified. –  caseyr547 Mar 18 at 7:53

if those kinds of breathing techniques help you would prolly respond well to mediation as well. you can do a non-religious form which will increase mindfulness –  caseyr547 Mar 18 at 8:13

Yup; basically, it works. Varvogli and Darviri (2011) review research on diaphragmatic breathing, reporting:

Deep breathing has been successfully used to decrease the fatigue associated with haemopoietic stem cell transplantation patients 55, to reduce the anxiety and asthma signs/symptoms of children with asthma 56, in the management of acute stressful tasks 57 showing that the slow-breathing technique can have a significant effect on improvement of the hemodynamic changes following the acute stressful tasks. Furthermore, it has been used to influence autonomic functions in patients with essential hypertension and thus reduce it 58–59, in the management of male adolescent aggressive behaviour 60, in long term prophylaxis of migraine 61, in stress related to dental visits 62.

Fatigue, anxiety, stress, and aggression are all negatively valent (see the diagram in this answer; aggression doesn't appear, but is a form of negative arousal). It wouldn't be surprising if effects on hypertension and migraine incidence are partially mediated by emotional changes either.

Nick. You probably don't know but these answers full of references are breathtaking. I guess I'm in love with you. :3 –  Vÿska Mar 20 at 6:51

"Breathtaking" eh? I see what you did there! :D I'll have to check out your other questions and see if I can capitalize on your high regard for me ;) Don't give me too much credit on this one though! Varvogli & Darviri (2011) was one of the first Google hits for something like "deep breathing negative emotion research", and I really just copied and checked references from their article, since it happened to include a decent review already (the quoted section above). –  Nick Stauner Mar 20 at 15:30
    
Yes. But it would be kinda hard for me to search. I'm not from cognitive sciences, but I do have interest in some things. I believe that my vocabulary for searching it in my native languange is poor, but it should be much worse in english. Thanks anyway. :) –  Vÿska Mar 21 at 9:46

Oh, I wasn't suggesting that you should've found this stuff on your own, just that I didn't do anything too amazing for this answer :) But do give it a shot whenever you have a question! You'd be amazed at how easy it is to find useful research sometimes! Especially by searching with the word "research" ;) Feel free to ask me for help in choosing keywords too if you don't have full-fledged questions to ask here...and clearly no harm done in asking this one. It's pretty popular already! –  Nick Stauner Mar 21 at 17:34

Nick's answer is very thorough. I would add that the physiological symptoms of high-stress (muscle tightening, accelerated heartbeat, shallow quick breath) can be reversed by controlling breath voluntarily. So, when you change these physical conditions, emotional state often follows.
