Why it matters
Your breath can shift your body faster than most people realize. A tight, shallow pattern can keep stress signals active, while slower and more deliberate breathing can help lower tension. The hard part is that the wrong pace or method can make some people feel lightheaded or more alert, not calmer.
Diaphragmatic breathing
Diaphragmatic breathing means drawing air lower into the torso instead of lifting the chest and shoulders. You should feel the belly expand first, with less movement in the upper chest.
A common mistake is forcing a huge inhale. That often creates neck tension and makes the breath feel mechanical. A smaller, softer inhale usually works better and is easier to repeat.
Try one hand on the chest and one on the belly. If the top hand keeps rising first, slow down and reduce effort rather than taking in more air.
