Deep breaths are more efficient: they allow your body to fully exchange incoming oxygen with outgoing carbon dioxide. They have also been shown to slow the heartbeat, lower or stabilize blood pressure and lower stress.
To experience deep breathing, find a comfortable place to sit or lie down. Breathe slowly and deeply through your nose, causing your stomach to rise and expand. Exhale fully.
“Breathing deep for a minute isn’t going to improve your lung capacity,” Hoyt said. “But deep breathing is a good way to reduce stress and relax.”
