Why Is Pain Important In Life?

Pain, often viewed as an unwelcome sensation, is actually an key component of our body's health and signaling system. One of pain's main jobs is to serve as a warning sign, alerting us to potential threats or harm.

In 2020, the International Association for the Study of Pain (IASP) revised the definition of pain, which currently reads:

An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage.”

Why Is Pain Important In Life? Check Out The Benefits

Pain alters the quality of life more than pretty much any other health-related problem. Pain interferes with sleep, mobility, nutrition, thought, sexual activity, emotional well-being, creativity, and self-actualization. But pain is essential to our health, and indeed, sometimes to our very survival.

People who can't feel pain, (a condition known as Congenital Insensitivity To Pain and Anhydrosis (CIPA) is a very rare and extremely dangerous condition. Individuals with this condition rarely live past the age of 25. Fortunately this condition is extremely rare and only affects about 1 in 125 million people.

The rest of us are often all too aware of pain in our lives, with as many as 80% of people experiencing problems like low back pain at some point in their lifetimes. So why is pain important in life? Let's take a look!

pain helps warn us about danger and physical injury

1. Protective Mechanism

One of the most important jobs that pain has is to act as a protective mechanism, alerting us to injuries or potential harm. When we touch a hot stove or stub our toe, the sensation of pain signals the body to move away from the source of injury, preventing further damage.

Without pain, we would be oblivious to injuries, which could leading to more severe injuries or consequences and even shorter life spans.

Research published in the journal Nature Neuroscience suggests that pain perception involves complex neural pathways that help us avoid harm and ensure survival.

pain can act as a diagnostic tool

2. Diagnostic Tool

Pain serves as a diagnostic tool, helping healthcare professionals identify underlying health issues. Different types of pain, such as sharp, dull, or burning sensations, can provide important insights and clues about the nature and location of the problem someone is experiencing.

By understanding the characteristics of pain, medical professionals can make accurate diagnoses and initiate appropriate treatment plans.

Studies published in medical journals like Pain Medicine highlight the importance of pain assessment in diagnosing conditions ranging from musculoskeletal disorders to neurological diseases.

Pain plays a crucial role in the healing process

3. Promotes Healing

Pain plays a crucial role in the healing process by signaling inflammation and tissue damage. When tissues are injured, the body's inflammatory response triggers pain receptors, leading to localized discomfort. This inflammatory pain helps mobilize immune cells to the site of injury, facilitating tissue repair and regeneration.

Scientific evidence: Research published in the Journal of Orthopaedic Research demonstrates the link between pain perception and the inflammatory response, emphasizing its role in tissue repair mechanisms.

pain is often there to protect us from overexerting ourselves

4. Prevents Overexertion

Pain acts as a natural limiter, preventing us from overexerting ourselves and causing our bodies any more injury or harm. For example, having sore muscles after a strenuous exercise session acts as a reminder to us that we need to rest and allow our bodies to recover.

Without this feedback mechanism, we might end up pushing ourselves beyond our limits, increasing our risk of injury or exhaustion.

Scientific evidence: Studies in exercise physiology, such as those published in Sports Medicine, highlight the role of pain perception in regulating exercise intensity and preventing overtraining.

mindfulness and meditation can help reduce chronic pain

5. Promotes Adaptation

Chronic exposure to low levels of pain can actually promote adaptation and resilience. Over time, individuals learn to cope with persistent pain through various strategies, such as mindfulness techniques, adaptive behaviors, and social support networks.

While chronic pain presents significant challenges, it can also foster personal growth and resilience in individuals who learn to navigate its complexities.

Scientific evidence: Research in psychology and pain management, including studies published in Pain Research and Management, explores the adaptive strategies individuals use to cope with chronic pain and enhance their quality of life.

chronic pain can have a profoundly negative effect on our lives

Understanding Chronic Pain

Acute pain serves a protective role whereas chronic pain represents an inappropriate response where the pain and discomfort last well beyond the normal healing process.

Chronic pain conditions, like low back pain, can have profound physical, emotional, and social implications, significantly impacting an individual's quality of life.

Low back pain, in particular, is one of the most common types of chronic pain, affecting millions of people worldwide.

Chronic pain can result from various factors, including injury, degenerative conditions, poor posture, and sedentary lifestyles. Unlike acute back pain, which typically resolves with rest and conservative measures, chronic low back pain persists for weeks, months, or even years, presenting a significant management challenge.

a multidisciplinary approach to managing chronic pain is essential

Managing Chronic Pain

While chronic pain conditions like low back pain can be debilitating, there are evidence-based strategies for managing and alleviating symptoms. Here are five effective approaches:

1. Multidisciplinary Pain Management

A multidisciplinary approach involving healthcare professionals from various disciplines, such as physicians, physical therapists, psychologists, and pain specialists, can provide comprehensive care for chronic pain patients. This integrated approach addresses the physical, emotional, and social aspects of pain, offering tailored treatment plans to meet individual needs.

Scientific evidence: Meta-analyses and systematic reviews published in journals like The Clinical Journal of Pain support the effectiveness of multidisciplinary pain management programs in improving pain outcomes and enhancing quality of life.

exercise is a great way to manage chronic pain conditions

2. Exercise Therapy

Exercise therapy, including strengthening, flexibility, and aerobic exercises, plays a crucial role in managing chronic low back pain. Regular physical activity helps improve muscle strength, flexibility, and endurance, reducing pain and disability. Additionally, exercise promotes the release of endorphins, natural pain-relieving chemicals that can alleviate discomfort and improve mood.

Scientific evidence: Clinical trials and meta-analyses published in journals such as The Cochrane Database of Systematic Reviews demonstrate the efficacy of exercise therapy in reducing pain and improving function in individuals with chronic low back pain.

cognitive behavioral therapy has been found to help with chronic pain

3. Cognitive-Behavioral Therapy (CBT)

Cognitive-behavioral therapy (CBT) is a psychotherapeutic approach that helps individuals identify and modify unhelpful thoughts, emotions, and behaviors associated with chronic pain. By addressing negative beliefs and coping strategies, CBT empowers patients to develop better coping skills which then reduces the impact of pain on their daily lives.

Scientific evidence: Research published in journals like Pain and The Journal of Pain highlights the effectiveness of CBT in reducing pain intensity, disability, and psychological distress in individuals with chronic pain conditions.

mindfulness and meditation can help relieve chronic pain

4. Mindfulness and Relaxation Techniques

Mindfulness-based treatments like meditation, progressive muscle relaxation, and deep breathing exercises, can help individuals manage chronic pain by promoting relaxation and stress reduction. These techniques enhance self-awareness and acceptance, allowing individuals to cultivate a compassionate attitude towards their pain experience.

Scientific evidence: Systematic reviews and meta-analyses published in journals like JAMA Internal Medicine and Pain Management Nursing support the efficacy of mindfulness and relaxation techniques in reducing pain intensity and improving psychological well-being in chronic pain patients.

not all medications help with chronic pain conditions

5. Pharmacological Interventions

Pharmacological interventions (medication), including nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, antidepressants, and anticonvulsants, may be prescribed to manage chronic low back pain.

These medications are often used to help alleviate pain, reduce inflammation, and improve mood and sleep quality in some individuals. However, it's essential to use medications properly and under the guidance of a healthcare professional to minimize the risk of side effects and dependency.

opioids often do not work for chronic pain conditions

With that being said, there are some medications, like opioids and gabapentin, that are often used to treat low back pain that may not be supported by experts or international guidelines. You should read the science and speak to your doctor before starting any type of medication for back pain.

Scientific evidence: Clinical guidelines and randomized controlled trials published in journals like The Journal of the American Medical Association (JAMA) provide evidence-based recommendations for the pharmacological management of chronic low back pain, emphasizing the importance of individualized treatment plans and monitoring for adverse effects.

Pain is a critical aspect of our body's defense mechanisms


Pain, though often viewed as something of a nuisance, is a critical aspect of our body's defense mechanisms. Pain serves as a warning sign, a diagnostic tool, and a catalyst for healing. While acute pain plays a protective role, chronic pain presents a more complex challenge that requires a multidimensional approach to management.

When we understanding the benefits of pain and we implement evidence-based strategies for managing chronic pain conditions like low back pain, we can regain control of our lives and live a life of wellness.
