The easiest, most convenient and most effective technique and practice for regulating your nervous system is the slow breath. I mean, you're already breathing - just switch it up a little bit and your nervous system will thank you! Our bodies are stressed even though we may not feel it as a "feeling". Practicing the slow breath frequently and consistently is the first step in bringing regulation to your stressed out systems. Do it when you're not feeling stressed. Do it when you are feeling overwhelmed. Do you it when you wake up. Do it when you sit on the toilet. Do it in the shower. Do it when you are ready to sleep. Do it when you are driving. Do it in the line at the grocery store. Do it so often it just becomes part of your everyday. Vagus Nerve stimulation is all the rage these days - everyone has a device to sell but what if you could do all of that with just your breath? Sounds too simple but I assure you, it's true - you can. And you must. Inhale slowly - hold for a couple of seconds - exhale (slow and longer than the inhale) - hold at the bottom for a couple of seconds. Repeat. https://nhahealth.com/longer-exhalations-are-an-easy-way-to-hack-your-vagus-nerve/
