But if you intentionally focus on slowing your breathing, even during moments of stress or “fight-or-flight,” it can trigger the parasympathetic nervous system response. Practice taking slow deep breaths from the diaphragm.

What drugs stimulate the parasympathetic nervous system?

Parasympathomimetics are a class of medications that activate the parasympathetic nervous system by mimicking or modifying the effects of acetylcholine. These drugs include muscarinic receptor agonists (direct-acting parasympathomimetics) and acetylcholinesterase inhibitors (indirect-acting parasympathomimetics).

How does sympathetic and parasympathetic affect the heart?
