The mind interprets this lower in stress as a sense of reduction,” she says.
Sheth compares it to holding in urine. “If you happen to’ve ever needed to maintain in your urine for a very long time since you could not go to the lavatory, after which let it go, you know the way it feels.”
For folks with delicate digestive techniques, corresponding to these with irritable bowel syndrome (IBS), this reduction is even better, decreasing bloating, fuel, and cramps.
