When we get news of the death of a loved one, our emotional and physical state can go from one of calm to sudden extreme stress, including a range of emotions such as shock, fear, sadness and anger. This response is caused by the different parts of our autonomic nervous system (ANS). The sympathetic, parasympathetic, and vagal nerve are key parts of the ANS, which controls involuntary functions in your body. Here's a breakdown of how they work together: 1. Sympathetic Nervous System (SNS) – "Fight or Flight” The SNS is like your body's "gas pedal." It gets activated when you're stressed, fearful, or in danger. It prepares your body to respond to a challenge by increasing heart rate, dilating pupils, slowing down digestion, and redirecting blood flow to muscles for quick action. Essentially, it's the system that gets you ready to run away from danger or deal with a stressful situation. 2. Parasympathetic Nervous System (PNS) – "Rest and Digest" The PNS is like your body's "brake." It works to calm things down after the SNS has done its job. It slows the heart rate, promotes digestion, and helps with rest, recovery, and overall energy conservation. It's the system that helps you relax and recover, bringing you back to a balanced, calm state after a stressful event. 3. Vagus Nerve – "The Bridge Between Both" The vagus nerve is a crucial part of the parasympathetic system and acts like a communicator between your brain and organs. It is the longest nerve in the body and travels from the brainstem down to the abdomen. It helps control heart rate, regulates digestion, and reduces inflammation. It’s particularly important for calming your body down after stress, essentially counteracting the effects of the sympathetic system. The vagus nerve has two states: The ventral (front) vagus state is the calm connected state that supports social engagement and feelings of safety. The dorsal (back) vagal state responds to life threatening situations or danger and can result in a state of freeze or shutdown. How They Work Together: When you're stressed due to a loss (SNS activation), your heart rate increases, muscles tense up, and digestion slows. But once the stress eases, the parasympathetic system (especially the vagus nerve) activates to calm everything down. The vagus nerve helps reset your body’s balance, ensuring you don’t stay in "fight or flight" mode for too long. Activities to restore a sense of calm When grief is impacting your ability to perform day to day tasks, attempt to identify what state you are in and try some of these activities to stimulate the vagus nerve to help restore a sense of calmness and safety. 1. Deep, Slow Breathing Why it works: Long, slow exhales signal safety to your brain and activate the vagus nerve. Inhale for 4 seconds Hold for 4 Exhale for 4 Hold for 4 Repeat for a few minutes. Or just keep your exhale longer than your inhale (e.g., inhale 4, exhale 6–8). 2. Humming, Singing, or Chanting Why it works: The vagus nerve connects to your vocal cords and throat. Hum your favourite tune (or "om" like in yoga) Sing out loud in the car or shower Chanting or even reading aloud counts too 3. Gargling Why it works: It stimulates muscles in the back of your throat that the vagus nerve controls. Gargle with water a few times a day — go deep and loud if you can! 4. Social Connection Why it works: Safe, warm interactions help activate the vagus nerve and calm the nervous system.
