Is it possible to toughen up your nervous system? In this final article of the Science of Pain Thresholds series, we explore whether pain tolerance can be improved—and how. We look at evidence from elite athletes, chronic pain patients, military training, and mindfulness research to answer this burning question. Spoiler: You might be more adaptable than you think.
Why does one person barely flinch during a tattoo while another taps out in ten seconds? Can we train ourselves to handle more pain—or is tolerance hardwired? This article tackles those questions and more. We’ll unpack the science behind pain tolerance, clarify what influences it, and explore whether mindset, exposure, fitness, or even meditation can help you increase your tolerance over time. If you’ve ever wondered whether you can train your body and mind to handle discomfort better, this one’s for you.
Pain tolerance isn’t set in stone. While genetics and biology play a role, research shows that our brains, bodies, and even mindsets can adapt over time. Pain tolerance is shaped by many factors including your genetics, environment, psychology, and lifestyle. While you can’t completely change your biological wiring, you can train your mind and body to handle discomfort better. From mental strategies like mindfulness and cognitive reframing to physical conditioning and gradual exposure, there are safe and science-backed ways to expand your limits. Through physical training, gradual exposure, mental strategies, and lifestyle changes, it’s possible to push the limits of what we can comfortably endure — without ignoring our body’s warning signals.
Understanding Pain Tolerance vs. Pain Threshold
- Pain threshold = the point at which something (a stimulus) starts to feel painful.
- Pain tolerance = how much pain you can handle once it starts (the maximum amount of pain you’re willing or able to endure).
Example: If two people both start feeling pain at the same pressure on the skin, but one can endure it longer, that person has a higher pain tolerance.
Pain tolerance is shaped by complex interactions between biology (nerve sensitivity, neurotransmitters), psychology (coping skills, mindset), and environment (previous exposure to pain, cultural expectations).
Why Pain Tolerance Matters
A higher pain tolerance can help in daily life, sports, and even recovery from injury. It’s not about becoming reckless — it’s about better handling inevitable discomfort so you can stay active, manage medical procedures more calmly, and recover more effectively.
Improving pain tolerance means training yourself to cope with discomfort, not magically becoming immune to pain signals.
Why Would Someone Want to Increase Pain Tolerance?
- Athletes: Push through fatigue or discomfort in training/competition.
- Chronic pain patients: Better manage day-to-day discomfort without escalating medication use.
- Emergency situations: Stay functional under injury or stress.
- Everyday benefits: From getting a vaccine without anxiety to recovering more comfortably after surgery.
The Brain’s Role in Pain Tolerance
Pain isn’t just a physical sensation; it’s a brain interpretation of signals from the body. The prefrontal cortex, amygdala, and periaqueductal gray are all involved in processing and modulating pain. Mental training can change how these areas respond, making discomfort feel less overwhelming.
Your perception of pain isn’t purely physical—it’s filtered through your brain’s interpretation.
- Prefrontal cortex: Involved in decision-making and reappraisal (“This is temporary, I can handle it”).
- Endorphins and enkephalins: Natural painkillers released during stress or exercise.
- Placebo effect: Expecting pain to be less severe can actually make it less severe.
Psychological Strategies to Improve Pain Tolerance
Techniques such as mindfulness, breathing exercises, and visualization can change the way you interpret pain signals. Mental strategies play a key role when it comes to relating better with pain.
a) Mindfulness Meditation
- Teaches you to observe pain without judgment, reducing its emotional “volume.”
- MRI studies show mindfulness alters brain activity in pain-processing regions.
b) Cognitive Reframing
- Changing how you think about pain (“This burn means my muscles are getting stronger”) shifts the body’s response.
c) Breathing Techniques
- slowing the breath to reduce sympathetic nervous system activation.
d) Stress Management
- Chronic stress heightens pain sensitivity and lowers pain tolerance by keeping the nervous system in fight-or-flight mode.
- Breathwork, yoga, and relaxation training help keep the nervous system in balance.
- Visualization: focusing on an image or scenario that shifts attention away from discomfort.
Physical Strategies to Improve Pain Tolerance
a) Gradual Exposure: The Science of Desensitization
Athletes, musicians, and people in physically demanding jobs often develop higher pain tolerances through repeated exposure to discomfort. Controlled, gradual exposure (like cold water immersion or incremental training intensity) can train the nervous system to become less reactive.
- Similar to training a muscle, small, safe doses of discomfort (cold showers, light endurance training) can build tolerance over time.
b) Exercise: Physical Training & Conditioning
Regular exercise improves pain tolerance. Endurance sports in particular (running, cycling, swimming) train the body to work through discomfort while avoiding injury. Strength training also builds resilience, as your muscles, tendons, and nervous system adapt to physical stress.
- Regular aerobic and strength training boosts circulation, endorphins, and resilience to pain.
c) Sleep & Recovery
- Sleep deprivation lowers pain tolerance significantly. Prioritizing recovery supports resilience.
- Poor rest makes pain feel more intense!
Nutrition & Biochemical Support
- Anti-inflammatory diets can reduce background discomfort.
- Omega-3 fatty acids: Anti-inflammatory properties may help manage pain sensitivity.
- Magnesium: Supports nerve health and muscle relaxation.
- Adequate hydration: Even mild dehydration can amplify discomfort.
Important Caveats
Know when to respect your limits! While it’s possible to improve tolerance, pushing too far can cause harm. Pain is a protective signal — ignoring it completely risks injury. Improvement is about knowing when to lean in and when to step back.
- Increasing pain tolerance isn’t about ignoring injury signals—pushing too far can cause harm.
- In chronic pain, the goal is often modulation, not elimination of sensation.
- Always seek guidance before starting extreme tolerance training (e.g., ice baths, fasting, or high-intensity endurance work).
Practical Ways to Improve Pain Tolerance (check em off)
- Start small — build discomfort gradually.
- Use mental focus tools like meditation.
- Stay consistent with physical activity.
- Maintain good sleep and nutrition habits.
- Mix both physical and mental training for best results.
- Monitor for warning signs of injury or illness.
While your pain threshold is partially fixed, your pain tolerance is surprisingly flexible, and trainable. The mind-body connection plays a huge role, and by working both angles—training your physical resilience while also building mental coping tools—you can safely expand your limits. Through consistent practice, both the body and brain can adapt to handle discomfort more effectively. The goal isn’t to chase pain but to learn how to navigate it wisely, improving performance, recovery, and everyday resilience.
For example, an athlete might combine mindful breathing with progressive endurance workouts to handle training discomfort better. Someone recovering from surgery might use relaxation techniques alongside gentle mobility work to improve recovery.
The important thing? Pain is a signal, not an enemy. The goal isn’t to override it completely, but to become more skilled in listening, interpreting, and responding to it. With patience, awareness, and science-backed strategies, you can increase your tolerance and reclaim control over how pain affects your life.
