"just be confident bro"
<doesn’t know that confidence is a reflection of GABA levels and receptivity>
Mouthbreathing is for anxious people.
You ever see James Bond breathing through his mouth when things get tough?
Rarely.
Mouthbreathing takes stimulation away from the Vagus nerve which in turn lowers parasympathetic activity (when GABA is released) and increases all kinds of stress hormones (Estrogen, serotonin, cortisol, adrenaline etc.)
Nose breathing also helps this by expanding the face/cranium and improving the flow of CSF, which pumps GABA through the brain and spinal cord.
if we are at it, nosebreathing also enhances GABA production by slowing the time it takes to exhale.
short exhales deplete a lot of CO2 whereas long exhales don’t.
CO2 is protective against stress and hence GABA will rise.
Then, inhaling (properly) widens the face/skull. Active exhalation causes the face to become narrower. People with narrow faces/skulls are chronically forcing the exhalation portion of the breath rather than a passive exhalation. This reduces CO2 and GABA.


A passive (slow) exhalation is what people should do 99% of the time. Short forced exhalers will have narrower skulls and lower CO2/GABA levels.

Amino profile also matters, aminos like Taurine and Glycine promote GABA synthesis whereas Methionine tends to activate a GABA lowering stress response.
- Co2 tolerance (which correlates with palatal width)
- Sleep
- Light environment
- Nutrient intake
