Get more energy, manage your emotions better, live longer, be happier, simply by adopting a smooth and regular breathing while you work.
Do this for a few days and you will notice that your breathing will become smoother, slower, and more regular even when you're not actively paying attention to it.
Although we can't change our chronological age we can change our biological age and increase HRV with the right kind of lifestyle adjustments. It is therefore possible to improve HRV and turn back the clock through exercise, emotional self-management, omega-3 supplements and yoga. The easiest and quickest way however is to create cardiac coherence through [these] breathing skills.
And how breathing affects it:
Generating a rhythmic breathing pattern creates cardiac coherence. The rhythmic changes in intrathoracic pressure caused by rhythmic breathing cause the heart rate to vary in a dynamic stable way. As our cardiac physiology becomes coherent the power output of the heart increases, and this drives other biological systems to synchronize with the heart causing physiological entrainment.
Background soundtracks help me focus, and have tried listening to natural sounds (ocean waves, rain) or electronic ones (drones, procedural music). But most online soundtracks are using compressed audio of bad quality, and some use very short loops which soon become irritating.
I was also looking to improve my breathing but most breathing apps or devices require active attention, and I wanted something I could use in the background while working.
So I experimented with Max/MSP and came up with a prototype that I used almost daily for about two months. I went for the simplicity of pure white noise, filtered at a varying frequency, which results in a very non-intrusive sound, halfway between natural and artificial.
