Why Does Stress Keep Your Body Stuck in Fight-or-Flight, and How Can Neurologically Focused Chiropractic Help in Pasadena, MD?

A nervous system chiropractor looks at how stress can keep the body in fight-or-flight, where the sympathetic nervous system stays more active than the calming parasympathetic side. Dr. Michelle Herczeg uses INSiGHT Scans, including heart rate variability, to measure that balance, then offers gentle, specific adjustments that aim to support regulation.

What does a nervous system chiropractor mean by fight-or-flight?

Fight-or-flight is the job of the sympathetic nervous system, the part of the autonomic nervous system that helps you respond to danger or pressure. According to Cleveland Clinic, it raises your heart rate, relaxes your airways, and slows digestion so energy goes where it is needed most. Its partner, the parasympathetic nervous system, has an opposite but complementary role and helps the body rest, digest, and recover. The two are meant to take turns throughout the day. A nervous system chiropractor pays close attention to how well that switching happens. When stress piles up from work, school, screens, poor sleep, or an old injury, the body can spend more time on the stress side than it needs to. Cleveland Clinic notes that anxiety and chronic stress can strain the sympathetic nervous system.

How does the vagus nerve help your body shift into rest and digest?

The vagus nerve is the main pathway of the calming side of your nervous system. Cleveland Clinic explains that it makes up about 75% of the parasympathetic nervous system and connects to the heart, lungs, and other internal organs. When parasympathetic activity is working well, it helps lower your heart rate and supports digestion. That is why people sometimes describe the vagus nerve as the body's brake pedal. If the brake is rarely used, it can be harder to settle down after a stressful moment, fall asleep at night, or digest a meal comfortably. The PX Docs approach looks closely at vagus nerve function and dysautonomia, which in this setting describes a nervous system that seems stuck in stress mode rather than shifting smoothly between fight-or-flight and rest-and-digest.

What are signs of a stressed nervous system in Pasadena adults and kids?

Stress shows up differently at every age, so it helps to know what to watch for. Adults may notice trouble winding down, restless sleep, a short fuse, tension in the shoulders and jaw, or digestion that changes during a busy week. In children, Mayo Clinic Health System lists signs such as difficulty falling or staying asleep, trouble concentrating, stomachaches, headaches, and emotional outbursts. The American Academy of Pediatrics also points to restlessness, tiredness, and irritability as signs of overload. These signs have many possible causes, so a pediatrician or primary care provider should evaluate new or worsening symptoms. For Pasadena families, simply noticing patterns at home is a helpful first step. Common signs include:

• Sleep: trouble falling asleep, frequent waking, or new nightmares
• Focus: difficulty concentrating at school, at work, or during homework
• Digestion: stomachaches, appetite changes, or irregular bowel patterns
• Tension: a clenched jaw, tight shoulders, or a body that rarely relaxes
• Mood: irritability, outbursts, or pulling away from family and friends

What can heart rate variability on INSiGHT Scans show about stress?

Heart rate variability, or HRV, measures the small changes in time between heartbeats. Researchers use HRV as a window into autonomic function, and a 2018 review in Psychiatry Investigation found that stress is most commonly linked with lower parasympathetic activity on HRV measures. At Severna Park Family Chiropractic, HRV is one part of the INSiGHT Scans, alongside surface EMG and thermography. Together they create a neural profile and a CORESCORE that help Dr. Herczeg explain how your nervous system is adapting to stress. HRV is not a diagnosis, and a single reading does not tell the whole story. What makes it useful in a chiropractic setting is tracking over time: rescans show whether the balance between fight-or-flight and rest-and-digest appears to be shifting as care continues.

How can neurologically focused chiropractic support regulation for the whole family?

Neurologically focused chiropractic care aims to reduce nervous system stress so the body can shift more easily between fight-or-flight and rest-and-digest. Dr. Herczeg uses gentle, specific adjustments, chosen for each patient, based on where scans show subluxation and dysautonomia. Care is not a replacement for medical or mental health treatment, and it fits well alongside healthy habits. It also helps to see stress as a family pattern. Harvard Health describes co-regulation as a warm, responsive process in which caregivers help children handle upsets, and notes that emotions spread between people. A stressed parent can make it harder for a child to settle, while a calmer parent can help a child feel safe. That is one reason parents are welcome to start family care alongside their kids.
