Anyone else enjoy a good horror movie? Notice how your heart races, your face flushes, your eyes widen and your hearing sharpens? That’s your body’s survival system kicking in. These automatic responses are largely controlled by the vagus nerve. But when the nerve is constantly activated by stress, your body starts to feel the effects in unhealthy ways.
What makes you feel safe — your couch, your bed, your patrol car at the end of shift? That sense of comfort is also the vagus nerve at work. It’s processing your environment and telling your brain you’re safe enough to stand down.

Understanding the vagus nerve
The vagus nerve starts just below the brain and splits into two main branches:
- Vasovagal (front)
- Dorsovagal (back)
It travels through the body, regulating functions such as blinking, breathing, digestion, kidney function, sneezing and even goosebumps. It’s one of the most important — and sensitive — nerves in your body.
The vagus nerve is central to the autonomic nervous system, which governs fight, flight, freeze or fawn responses. For officers, these reactions often happen in high-stress encounters without conscious thought. While protective, they can also keep you in a state of hypervigilance long after the call ends.
9 ways officers can support vagus nerve health
These small, intentional actions can help regulate your vagus nerve. They may reduce hypervigilance, improve sleep and strengthen emotional control — key benefits during long shifts and high-pressure work.
1. Stretch before shift: Loosen joints, reach toward your toes and move for a few minutes. This signals your body to transition from rest to readiness.
Shift-ready tip: A quick stretch routine can prevent stiffness from long patrol hours in the car.
2. Start with cold water: Before coffee or an energy drink, drink a glass of cold water. It stimulates the vagus nerve and helps prepare your system for the day.
Wellness note: Cold water wakes up your system faster than caffeine and avoids the crash.
3. Self-holding with gentle twisting: Cross your arms, hold your vest or shoulders and slowly twist side to side. This grounds you and calms both vagal branches after stressful calls.
Officer tip: Useful in the car after a tense scene before heading to the next call.
4. Box breathing (tactical breathing): Inhale 4 seconds → hold 4 → exhale 4 → hold 4. Repeat at least 5 times. This proven technique helps regain control in high-stress encounters.
Training reminder: Same technique taught in firearms and defensive tactics — easy to practice anywhere.
5. Relax your voice: After a tense shift or call, soften your jaw and speak gently. A calmer tone reduces your own stress response and can de-escalate interactions.
De-escalation note: Good for supervisors and FTOs when giving direction under stress.
6. Jaw tapping: Lightly tap along your jawline to release tension — helpful after hours of radio traffic or clenched stress.
Practical use: Try during report writing breaks or long surveillance ops.
7. Protect your secure space: At home, set boundaries. Don’t take routine work calls or emails unless it’s a true emergency. Your vagus nerve needs downtime to recover.
Wellness reminder: Rookie officers often struggle with this — set boundaries early.
8. Practice active listening: Engage fully with family, friends and community members. Genuine connection activates the vagus nerve differently than on-duty hyperawareness.
Community policing tip: Listening first can calm tense conversations and build trust on the street.
9. Mentally list categories: Instead of replaying calls or building to-do lists, list things like dog breeds, sports teams or countries. This safe mental exercise shifts focus and relaxes your nervous system.
Stress relief note: Useful after tough calls to redirect thoughts before going home.
Keeping your vagus nerve balanced helps officers reset after stress, sleep better and stay healthier for the long haul. A few minutes each day can pay off in performance, resilience and overall well-being.
