What is Stress?
Stress is a natural part of life, but sometimes it can feel overwhelming. When we’re stressed, we may overestimate the severity of the stressor and underestimate our own ability to cope. This often triggers a cycle known as “stress reactivity,” where we become so accustomed to feeling stressed that it becomes almost a habit. Much like repeatedly practicing a skill until it becomes second nature, our bodies can become highly efficient at staying in “stress mode.” Unfortunately, this state can have far reaching negative impacts on both our mental and physical health.
According to research from Oxford University (Cohen, Kessler and Gordon 1995), stress is defined as a process where environmental demands strain an organism’s adaptive capacity, leading to psychological demands and biological changes that increase the risk of illness. Chronic stress doesn’t just weigh on our minds; it affects our bodies, potentially leading to serious health problems if left unchecked. However, how we respond to stress makes a significant difference in its impact on us. Through mindful practices and effective stress management strategies, we can mitigate stress and build resilience, leading to better overall wellbeing.
In essence, stress is the mind’s interaction with the environment. A certain amount of stress is necessary for growth; it sharpens our awareness and enhances our ability to adapt. Stress, when managed well, can shift us from a state of languishing to one of flourishing. The ancient philosopher Marcus Aurelius observed that stress isn’t in the event itself but in how we interpret it. This perspective remains valuable today; it reminds us that we have some control over our reactions to stressful situations.
Interestingly, the mind’s response to stress mirrors the body’s digestive system. Just as the digestive system breaks down food for nutrients, the brain (particularly the limbic system) processes and “digests” experiences. If we fail to process our stress, it may linger, much like undigested food. But when properly managed and “digested”, stress can be transformed into wisdom, enriching our life rather than diminishing it.
Ultimately, the process of handling stress helps us grow and adapt, but it does come at a small price; as we age, our resilience might require more conscious effort.
As Hans Selye, a pioneering stress researcher, famously said, “Every stress leaves an indelible scar, and the organism pays for its survival after a stressful situation by becoming a little older.” This reminder emphasises the importance of managing stress to not only maintain mental and physical health but also to improve quality of life as we age.

The Different Types of Stress
Stress is a complex experience that comes in various forms, each impacting us in unique ways. Not all stress is harmful, some types can even drive growth and motivate us toward our goals. Understanding the different types of stress and their effects on the body and mind is essential to managing them effectively.
Eustress vs. Distress: The Good and the Bad
Stress can generally be divided into two categories: eustress and distress.
- Eustress is often referred to as “good stress.” This type of stress encourages motivation, growth, and innovation. Eustress can help us tackle challenges, push our limits, and achieve our goals. It’s the kind of stress you might feel when starting a new job or learning a new skill; stress that ultimately has a positive impact.
- Distress, on the other hand, is “bad stress.” It leads to negative reactions such as confusion, overreaction, poor concentration, and performance anxiety. When in distress, our productivity and overall wellbeing suffer, often resulting in under performance. Distress is the kind of stress we want to minimise or manage effectively.
Environmental, Psychological, and Biological
Stress can also be categorised based on its source:
- Environmental Stress is related to objective demands in our surroundings that require us to adapt. This includes changes in work, relationships, or living conditions that put pressure on us to respond or adjust.
- Psychological Stress stems from our subjective assessment of our ability to cope with life’s demands. This type of stress emphasises how we perceive and evaluate situations rather than the situations themselves. If we feel overwhelmed or doubt our ability to manage, psychological stress increases.
- Biological Stress involves the body’s physiological systems reacting to psychological and physical challenges. This type of stress is deeply connected to the body’s biological responses, like hormone release, which help us adapt to demands.

Acute Stress and Acute Stress Disorder (ASD)
Acute Stress is short-term stress that arises in response to a specific incident and typically resolves once the situation is over. However, in some cases, people may develop Acute Stress Disorder (ASD) following a traumatic event. ASD is also known as an acute stress reaction and may occur after experiencing or witnessing events such as:
- Natural disasters like floods, fires or earthquakes
- Physical or sexual assault
- Car accidents
- The sudden death of a loved one
- Receiving a life-threatening diagnosis
Symptoms of ASD can include flashbacks, intrusive memories, nightmares and avoidance of reminders of the event. People with ASD may experience emotional numbness, difficulty recalling details of the event, anxiety, sleep issues, irritability and trouble concentrating. Physical symptoms like a pounding heart, nausea, and shortness of breath can also accompany the condition.
ASD vs. PTSD: Understanding the Differences
Many symptoms of ASD closely resemble those of Post-Traumatic Stress Disorder (PTSD), but there is a key difference in diagnosis. ASD symptoms typically occur soon after the traumatic event and last less than 30 days. If these symptoms persist for more than a month, or if they appear later, PTSD may be diagnosed instead. While not everyone with ASD develops PTSD, experiencing ASD can increase the risk, making early intervention crucial.
Episodic Acute Stress
When someone frequently experiences acute stress, it is called episodic acute stress. This occurs when acute stress episodes happen regularly due to ongoing life circumstances. Common triggers for episodic acute stress include:
- Taking on too many responsibilities
- Working in an unusually demanding job
- Caring for a loved one with chronic issues
- Repeatedly encountering misfortune or “bad luck”
- Experiencing interpersonal conflicts
- Tending to interpret situations in catastrophic ways
Episodic acute stress can lead to exhaustion and frustration, impacting quality of life and health over time. Recognising the signs of episodic acute stress is essential to address the underlying issues and find healthier coping mechanisms.

Understanding the Causes of Stress and How They Impact Us
Stress is a universal experience, but the sources and intensity of stress vary widely. While some people thrive under pressure, others may find the same situations overwhelming. Understanding the primary causes of stress can help us identify our personal triggers and take proactive steps to manage them.
Work-Related Stress: The Leading Source
According to surveys, work stress ranks as the top stress trigger. Common causes of work-related stress include:
- Feeling unfulfilled or dissatisfied
- Heavy workload and excessive responsibilities
- Long hours without enough rest
- Poor management and unclear job expectations
- Dangerous work conditions
- Insecurity about advancement or job stability
- Public speaking requirements
- Discrimination or harassment
Life Stressors: Major Personal Challenges
Beyond the workplace, life events can profoundly impact stress levels. Life stressors often stem from major changes or traumatic experiences. Some examples include:
- Loss of a loved one
- Birth of a child or marriage
- Divorce or job loss
- Rising financial obligations including debt
- Chronic illness or injury
- Emotional challenges
- Traumatic events
When Stress Comes from Within
Not all stress is caused by external events; often it originates from within. Our thoughts, attitudes and expectations can contribute significantly to our stress levels. Some common internal stress triggers include:
- Fear and uncertainty: Exposure to news about issues like terrorism, global warming and health risks can create a sense of helplessness and anxiety
- Attitudes and perceptions: How we interpret events influences our stress levels
- Unrealistic expectations: Perfectionism and setting unreasonably high standards can lead to disappointment and frustration whenever things don’t go as planned
Our stress responses are shaped by our personalities. Some people are naturally resilient and able to “let things roll off their backs,” viewing stress as manageable and temporary. Others may experience stress more intensely, sometimes to the point of physical illness. Recognising our unique tendencies toward stress can help us find strategies that align with our personal coping styles.

A Tool for Measuring Stress
The Perceived Stress Scale (PSS) is a widely used tool that helps individuals assess their stress levels based on their perceptions. Developed in 1983, this scale remains popular today because it emphasises the idea that how we perceive and interpret our experiences often matters more than the events themselves.
The PSS is designed to highlight the subjective nature of stress. Imagine two people who have encountered the exact same events over the past month. One person may interpret these events as manageable and experience low stress, while the other may feel overwhelmed and score high on the stress scale. This difference arises not from the events themselves but from each individual’s perception.
By focusing on personal perception, the PSS provides valuable insights into how individuals feel about their ability to handle life’s demands. The tool underscores that stress is not merely a result of external circumstances but is deeply connected to our mindset and interpretation of situations.
Using the Perceived Stress Scale can be a helpful first step in recognising how we respond to daily stressors.
The Profound Impact of Stress on Health and Wellbeing
During stressful situations, our bodies release hormones that initiate the “fight or flight” response, raising our heart rate, breathing rate and blood pressure while creating tension in our muscles. In moderation, this response can help us navigate and overcome obstacles. However, chronic stress, or stress that persists over a long period, can have profound negative effects on both mental and physical health.
The Biological Toll of Stress
When stress becomes chronic, it strains several key systems in the body, including the central nervous system, the hypothalamic-pituitary-adrenal (HPA) axis, and autonomic functions. This wear and tear, known as allostatic load, accumulates over time, especially when life’s demands continually exceed our ability to cope.

The body’s stress response can be broken down into three stages:
- Alarm Stage: The initial “fight or flight” reaction kicks in. Hormones such as epinephrine, aldosterone and cortisol are released, increasing blood glucose for energy and preparing the body for rapid response. During this phase, physical and chemical changes signal the body to conserve energy for survival.
- Resistance Stage: The body begins adapting to the stressor, activating the parasympathetic nervous system to help restore balance. Cortisol production decreases but remains elevated as the body stays on high alert, continuing to mobilise resources to address the stressor.
- Exhaustion Stage: Prolonged stress exhausts the body’s resources, compromising the immune system and making the body more susceptible to illness. This stage marks the point where stress related health issues, such as cardiovascular disease and autoimmune disorders, can emerge.
Health Conditions Exacerbated by Stress
Stress plays a significant role in worsening or even triggering various health conditions, including:
- Mental Health Disorders: Depression, anxiety and Post-Traumatic Stress Disorder (PTSD). Chronic stress can lead to lower heart rate variability (HRV) and reduced GABA activity, both of which are linked to worsened mental health outcomes.
- Neurological Disorders: Conditions such as epilepsy can become harder to manage under stress due to its effects on the central nervous system.
- Digestive Issues: Stress can disrupt digestion, leading to conditions like Irritable Bowel Syndrome (IBS), Gastroesophageal Reflux Disease (GERD), and functional gastrointestinal disorders.
- Autoimmune Diseases: Conditions like rheumatoid arthritis and other autoimmune disorders can be aggravated by stress, as it weakens the immune system and increases inflammation.
- Cardiovascular Health: Stress contributes to heart disease by increasing blood pressure, cholesterol, and blood sugar levels, all of which elevate the risk for heart attack and stroke.
- Diabetes: Both physical and psychological stressors can impact blood glucose levels, altering insulin needs for those with diabetes.
- Headaches and Migraines: Stress is a common trigger for headaches and migraines, as it can lead to constriction and dilation of blood vessels in the head.

Chronic Stress and Long-Term Health Risks
Living with persistent stress has serious consequences for long-term health. Over time, elevated blood sugar, blood pressure, and triglycerides can increase the risk of life threatening conditions like heart disease, kidney disease and diabetes. According to Meridian Stress Management Consultancy in the UK, around 180,000 people in the UK die each year from stress-related causes. This data underscores the need for managing stress effectively to safeguard long-term health.
How Yoga Therapy Can Help Manage and Alleviate Stress
Studies have shown that mind-body practices like yoga can be effective in managing stress and improving symptoms of conditions worsened by chronic stress. Yoga-based interventions help improve vagal tone, which is associated with better heart rate variability, mood stability and digestion.
Through breathwork, mindful movement and meditation, yoga encourages us to pay closer attention to our bodies, thoughts and emotions. Yoga increases self-awareness, teaching us to recognise stress triggers and respond with calmness rather than reactivity. By integrating yoga into our lives, we can cultivate resilience not by simply pushing through challenges, but by learning to approach them with compassion, tolerance and grace.
Yoga therapy follows a structured course for stress management:
- Reducing Stress and Inflammation: Stabilising the mind through coordinated breath and movement or mantra.
- Integration: Developing harmony between mind and body.
- Building Strength, Capacity and Resilience: Growing a toolkit of practices to call upon in times of future stress.

Yoga Techniques for Stress Relief
1. Asana (Postures)
Specific yoga postures can activate the parasympathetic nervous system, responsible for our relaxation response. Asanas like forward folds, backbends, and twists release physical tension in areas prone to stress, such as the back and shoulders. When practiced mindfully, these poses help alleviate physical discomfort, reduce cortisol (the primary stress hormone) and create a sense of mental and physical release. Studies show that regular movement, even for 20-30 minutes daily, improves mood by releasing endorphins, our natural mood elevators.
In particular, restorative yoga offers profound benefits during times of high stress, injury, or life transitions. By using support and allowing ample time in each pose, restorative yoga gives the body the space it needs to rebalance and repair.
2. Pranayama (Breathwork)
Breathwork, a core component of yoga, has a direct effect on the nervous system. Alternate nostril breathing (Nadi Shodhana) can calm the mind, ease anxiety, and enhance mental clarity. Studies have shown that regular diaphragmatic breathing can modestly lower blood pressure and cortisol levels. When we extend our exhalations longer than our inhalations, we stimulate the vagus nerve, triggering the body’s relaxation response.

3. Meditation and Mindfulness
Meditation offers a powerful way to combat stress by cultivating present-moment awareness. When practised regularly, meditation promotes the release of dopamine and oxytocin – neurotransmitters associated with feelings of happiness and relaxation. Studies reveal that meditation can lower blood pressure and reduce cortisol levels, while also alleviating symptoms of depression, anxiety and anger. Mindfulness-Based Stress Reduction (MBSR), an evidence-based program incorporating mindful movement, meditation, and body scans, has shown remarkable effects in reducing stress levels and promoting emotional balance.
4. Lifestyle Practices for Stress Resilience
Maintaining a mindful lifestyle enhances the benefits of yoga. Self-care practices like adequate sleep, gratitude, support and compassionate self-talk contribute to mental wellbeing. By learning to speak kindly to ourselves – just as we would to a friend – we can break the cycle of self-criticism that often arises under stress. Sleep, in particular, plays a critical role in managing stress; poor sleep often exacerbates stress, creating a vicious cycle. Techniques like Yoga Nidra, a form of guided meditation, can improve sleep quality, which in turn enhances resilience against stress.
Scientific Evidence Supporting Yoga for Stress Management
A growing body of research underscores yoga’s effectiveness in reducing stress and improving mental health. A 2020 review of studies found that various forms of yoga significantly reduced perceived stress in healthy adults. Another 2018 study on yoga in gym settings found that participants practicing yoga experienced lower stress levels, reduced anxiety and overall improved well being.

Studies on breathwork also provide promising insights. For instance, a 2019 review found that slow, deep breathing exercises could reduce blood pressure and cortisol levels. A 2021 study with university students linked mindfulness practices with decreased psychological distress, highlighting the value of these techniques for stress management in younger populations.
Mind-Body Connection: Yoga’s Holistic Approach to Health
Yoga engages not only the physical body but also the subtle energy system described in yogic philosophy. Prana, or life-force energy, flows through the body and can be harnessed through yoga postures, breathwork, and meditation. As we practise, yoga helps release blockages in energy flow, cultivating a sense of vitality and emotional balance.
Moreover, by incorporating the principles of mindfulness, meditation, and breath awareness, yoga creates a stigma-free alternative for managing mental health. Unlike many conventional mental health interventions, yoga offers a holistic connection to one’s inner state, combining both physical and psychological components for comprehensive stress relief.
Yoga for Different Stages of Life
The benefits of yoga are not limited by age. For children and adolescents, yoga and meditation can offer valuable tools for handling stress and emotional challenges. Techniques such as deep breathing can help children focus and manage difficult emotions. Parents can practice these techniques with their kids, creating a shared experience that strengthens family bonds and emotional well being.

For older adults, yoga provides a gentle way to maintain mental health and quality of life. Depression and anxiety, common among the elderly, are risk factors for physical ailments like chronic pain. The mind-body benefits of yoga offer elderly individuals a means to manage these symptoms and improve both physical and mental health.
At any age, yoga therapy can empower individuals to address the root causes of stress and build long lasting resilience. Its unique combination of movement, breath, mindfulness and lifestyle practices makes it an ideal tool for managing the complex challenges of modern life. By incorporating yoga into our daily routine, we not only improve our capacity to handle stress but also enhance our overall health and sense of wellbeing. As K.N. Udupa suggests: “a balanced practice that combines physical postures, breathing exercises, and meditation is best suited to meet today’s demands for a healthier, more harmonious life”.
Our modern lives are not about trying to escape stress but instead using the ancient teachings of yoga to be able to navigate it with more ease, awareness and grace.
With heartfelt appreciation to my teacher Shanti Kelley, whose awareness and grace is woven throughout these words.
