Yes, deep breathing exercises are highly effective in reducing anxiety. By slowing the breath and engaging the diaphragm, the body activates the parasympathetic nervous system, which counters the stress response. This lowers heart rate, reduces muscle tension, and calms the mind. Techniques like box breathing or belly breathing are simple and can be practiced anywhere. Over time, consistent practice improves emotional regulation and resilience to stress. Deep breathing is often recommended as a grounding tool during moments of panic or overwhelming anxiety.
