What does Sit Spot Practice do to the body?
What the body does during Sit Spot Practice has not been measured directly, so the physical picture is drawn from studies of related calm, repetitive practices. In that research, heart-rate variability, a beat-to-beat marker of the rest-and-recover branch, shifted upward while physiological signs of anxiety fell after the activity (Lang et al., 2020). In the body this tends to register as breathing slowing, the shoulders dropping, and the braced, on-guard feeling easing, rather than as any dramatic change.
Vagal Tone
moderate EVIDENCE
As you settle into a familiar spot, breathing tends to slow and the shoulders drop as the body feels less braced. Those are signs of rising vagal tone, a measure of how actively the body's rest-and-recover branch is running. It has not been measured directly during Sit Spot Practice, but research on quiet, repeated ritual-like activity recorded shifts in heart-rate variability, a marker of vagal tone, alongside lower physiological signs of anxiety (Lang et al., 2020).
Parasympathetic Tone via Social Engagement System
moderate EVIDENCE
As you settle into your spot, the body often grows heavier and calmer, breathing slows, and the braced, on-guard feeling eases, signs of the parasympathetic branch, the body's rest-and-recovery system, taking stronger control. In studies of quiet, repetitive practice, physiological signs of anxiety measured lower and heart-rate variability shifted this way (Lang et al., 2020). Sit Spot Practice itself hasn't been measured like this, so treat the settling as a reasonable expectation rather than a proven effect.
Sympathovagal Balance
moderate EVIDENCE
Settling into stillness can loosen the body's held tension, so breathing slows and the shoulders begin to drop. In studies of quiet, repetitive practices, heart-rate variability shifted so physiological signs of anxiety fell, a move toward the body's rest-and-recovery balance, though Sit Spot Practice itself has not been measured this way (Lang et al., 2020).
Sympathetic arousal
moderate EVIDENCE
When stress leaves you keyed-up and on high alert, that is sympathetic arousal at work, the body's fight-or-flight activation that raises heart rate, quickens breath, and tightens muscles. In studies of quiet, repetitive practices this arousal measured lower after the activity (Lang et al., 2020), a shift practitioners often notice as tension slackening, breath slowing, and the wired, on-guard feeling easing as they settle into a familiar place.
Sympathetic Nervous System Activity
moderate EVIDENCE
Settling into a familiar outdoor spot, many people feel the shoulders and jaw loosen and the breath slow and steady, signs that the sympathetic nervous system, the branch that drives fight-or-flight arousal, is easing. This has not been measured in Sit Spot Practice itself; the expectation draws on studies of calm, repeated practices, where physiological signs of anxiety fell after the activity (Lang et al., 2020).
