just go

Dehydration impairs attention more than any other cognitive skill, with effects appearing before most people notice they're thirsty.

this is probably a distraction to funnel tax money to the beef industry (who raised their prices thanks to other trump polices of ridiculous bullsh't.) while rice and beans ARE a complete protein at a fraction of the cost, its just not manly enough; and rule #12 of Umberto Eco's points of fascism is the appeal of ultra manly-machismo-masculinity.

The study examined those with extensive experience with intense breathwork practices (such as Holotropic Breathwork and Conscious Connected Breathing). Cerebral blood flow dropped by about 42 percent during the breathwork sessions.

And it dropped in a region connected to stronger feelings of bliss and connectedness. At the same time, blood flow increased in regions associated with emotional memory.

The subjective scores were comparable to levels reported in psilocybin and LSD studies, not because the mechanisms are identical, but because brain pathways appear to overlap. 

While the study above used an intense technique best practiced under guidance, research shows that slower, gentler breathing delivers many of the same downstream benefits (reduced stress, lower anxiety, improved mood) through a safer, more accessible route.

The most studied home-friendly version is sometimes called coherent or resonance breathing: inhale for 4-5 seconds, exhale for 4-5 seconds, and repeat continuously for 5 to 10 minutes. That rhythm lands at roughly 5-6 breaths per minute, which research consistently associates with increased heart rate variability and parasympathetic activation, the physiological signature of a calmer nervous system.
