Why it matters for pain, stress and recovery
When people think about pain or injury, they usually focus on muscles, joints or something feeling “tight.” While those things can absolutely contribute to symptoms, there is another important system involved in how your body experiences pain and recovers from stress. That system is your nervous system.
Your nervous system controls how your body responds to stress, how your muscles activate, how you perceive pain and how effectively you recover. When it is balanced, your body can adapt well to both physical and mental demands. When it stays in a constant stress state, it can contribute to ongoing tension, fatigue and persistent pain.
The two main states of the nervous system
Your nervous system is constantly shifting between two main states.
The sympathetic nervous system is often known as the fight or flight response. This state prepares your body to deal with stress or a perceived threat. Heart rate increases, blood moves to the muscles, and the body becomes ready to react quickly.
The parasympathetic nervous system is commonly referred to as the rest and digest state. This is when recovery happens. Your body relaxes, blood flows to your organs to help you digest and tissues repair.
Both of these states are normal and necessary. The problem occurs when the body spends too much time in the stress response without enough time returning to recovery mode.
Signs your nervous system may be under stress
Do you feel like you’re doing the “right” things, such as stretching, exercising, or receiving regular treatment, but you’re not seeing the progress you hoped for? Often, the missing piece is noticing those signs and symptoms of chronic stress and then setting yourself tasks to shift your nervous system into rest mode.
Many people believe they are managing their stress reasonably well, even when their body is showing clear signs that it is under pressure. Your nervous system often signals when it is under strain. This can show up as poor sleep, digestive issues, getting sick more frequently, low energy, mood fluctuations, brain fog, or difficulty concentrating. Some people notice they constantly feel “switched on,” struggle to unwind at the end of the day, find themselves doomscrolling, avoiding tasks, or feeling like they should always be doing something.
It is important to understand that these symptoms are often the body’s protective response. They usually develops when the body is exposed to ongoing stress without enough time to recover. The body is trying to let you know that you need to rest, and this is the only way these symptoms will improve.
This stress can come from many sources, such as major life changes like moving house, starting a new job, or financial pressure. Emotional stress, such as grief, relationship breakdowns, or family challenges, can also contribute, as can ongoing work demands and burnout.
In simple terms, the body can remain in a constant state of alert.
Why is nervous system regulation important
It is not uncommon for me to see patients whose bodies are holding a significant amount of tension. When the nervous system is in a heightened stress state, muscles tend to stay guarded and sensitive, which can make the body feel stiff, reactive, or slow to relax.
Sometimes this can even influence how someone responds to treatment. If the body is very tense or on high alert, it may take longer for muscles to release or for the body to fully settle after an adjustment or manual therapy. This is not because anything is “wrong,” but rather because the nervous system is still in a protective mode.
When patients begin incorporating simple strategies that help calm the nervous system, the body often becomes more receptive to change. Muscles can relax more easily, movement can feel smoother, and recovery tends to improve.
Ways to support your nervous system
There are several simple strategies that can help regulate the nervous system.
Slow breathing can be very effective. Breathing deeply through the diaphragm and slowing the breath signals to the brain that the body is safe, which can help calm the nervous system. In one of our previous blogs, we talked through how to integrate belly breathing into your daily routine – breathing patterns.
Regular movement also plays an important role. Activities such as walking, gentle stretching, or yoga can help release physical tension and support circulation.
Sleep is another key factor. During sleep, the nervous system has a chance to reset and recover. Consistent sleep schedules, limiting blue light from screens in the evening, and using warmer or red-toned lighting before bed can help support the body’s natural wind-down process.
Spending time outdoors can also be beneficial. Being in nature and getting natural daylight can help regulate stress hormones and support a more balanced nervous system.
Listening to calming music or soundscapes can also help shift the body into a more relaxed state. Slower tempo music has been shown to help reduce heart rate and promote parasympathetic activity.
Reducing constant stimulation throughout the day can make a difference as well. Taking short breaks away from screens, stepping outside, or pausing for a few quiet minutes can help the nervous system reset.
Manual therapy may also help. Treatments such as soft tissue therapy, joint mobilisation and chiropractic adjustments can reduce muscle tension and support the body’s ability to move out of a heightened stress response.
Looking at the bigger picture
Pain and tension are rarely caused by just one factor. They are often the result of a combination of physical load, lifestyle habits and how the nervous system is responding to stress. Supporting the nervous system alongside the muscles and joints can help the body adapt, recover and function more effectively. If you are experiencing ongoing muscle tension, stress-related pain or difficulty recovering from activity, an assessment can help identify the contributing factors and create a plan to support both your physical health and nervous system regulation.
