When you’re feeling stressed or anxious, your breath can become shallow and rapid. Breathwork techniques like deep diaphragmatic breathing can help calm your nervous system and bring you back to a state of relaxation. Try taking a slow, deep breath in through your nose, expanding your belly as you do so. Then, exhale slowly through your mouth, releasing any tension. Another technique, box breathing, involves inhaling for four counts, holding for four, exhaling for four, and holding again for four. These simple exercises can quickly reduce feelings of stress and anxiety.
