    Understanding sustainability

    Going beyond the buzzword

    The planet is heating up, putting life and ecosystems at increasing risk. Social and economic inequalities, between and within countries, remain stubbornly high. We’ve all heard the buzzword “sustainability” given as a solution to these problems: if we can shift our systems to become more sustainable, we can cut down on carbon emissions and resource use while making societies fairer for all.

    However, what does sustainability actually <mean>, and what progress are we making towards it?

    Unpacking sustainability

    In 1987, the United Nations Brundtland Commission defined sustainability as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” This definition is still relevant today. Indigenous communities have long held the belief that we should care for our world in a way that ensures the well-being of future generations.

    Core components of sustainability

    The concept of sustainability has three core components:

    • environmental sustainability
    • economic sustainability
    • social sustainability

    Environmental sustainability

    Environmental sustainability focuses on protecting and preserving natural resources (like clean air, water, forests, and biodiversity) for future generations. Shifting toward renewable energy and reducing waste are key aspects.

    The environment and the economy

    Economic sustainability means supporting growth while ensuring resources are used efficiently and responsibly. Our largely linear economies follow a “take-make-use-dispose” formula. While we’ve shifted toward recycling, efforts are often insufficient: a 2019 study found only 9 percent of plastic waste in Canada is recycled. To be truly sustainable, we need a circular economy, where products and resources remain in circulation. Just 7.2 percent of the global economy is currently circular.

    Social sustainability

    The social dimension of sustainability is critical, relating to creating a world where everyone can meet their needs and access a good quality of life. This includes ensuring equity in transitions to more sustainable practices.

    Environmental justice

    Environmental justice highlights how vulnerable communities often bear the brunt of climate change and pollution. The Government of Canada is working on a strategy to promote environmental justice.

    Working toward a more sustainable world

    While individual action is important, governments and corporations also have a lot of power.

    Government commitments and action

    In 2015, Canada committed to the UN’s 17 Sustainable Development Goals (SDGs) to be achieved by 2030, covering environmental, economic, and social sustainability. While progress is being made, much work remains, particularly regarding persistent inequalities and increasing emissions from oil and gas projects.

    Corporate influence and power

    According to a recent study, 80 percent of global carbon dioxide emissions from 2016-2022 came from just 57 corporate and state producing companies. Corporations hold significant influence and often lobby against environmentally and socially beneficial practices.

    Individual agency

    Systemic change is needed, but individuals also have power. Be critical of corporate sustainability claims, as “greenwashing” is common.

    We should all try to make our lives sustainable, but don’t lose sight of the changes needed from governments and corporations. Using your voice to protest and vote are crucial ways to hold power to account.

    Harness the power of yoga during pregnancy and postpartum

    In today’s fast-paced society, many of us emphasize the value of “doing” and diminish the significance of downtime—a mindset that often extends into pregnancy.

    Expectant moms are frequently burdened by anxiety about managing responsibilities, whether it be maintaining workout routines throughout trimesters or focusing on household tasks during postpartum recovery. In reality, we’re not supposed to do it all (or do it the same).

    Here’s how to reclaim rest and tap into the benefits of yoga during this transformative period of motherhood.

    The pressure to be productive

    With the pace of modern life pulling our attention in various directions, we often end up in a continual state of reactivity. The pressure to be productive can impact everything from sleep quality to hormone regulation, both vital during pregnancy and postpartum to create a nurturing environment for ourselves and our little ones. Failing to allow ourselves time to heal and discover what it means to mother can lead to struggle.

    The power of rest

    How can we embrace downtime? What does it mean to truly rest? Rest isn’t necessarily about sleep quality but our capacity to simply stop and be. It’s our ability to downregulate the nervous system or take moments of conscious rest throughout the day.

    Whether pregnant or caring for a newborn, carving out time for rest allows us to surrender to our circumstances. How we think and relate to ourselves and others is rooted in our capacity to rest. Practicing conscious rest in pregnancy and postpartum can take many forms, such as reading a book, meditating while breastfeeding, or gentle stretching. It means letting go of the pressure to run outdoors or clean before the baby wakes.

    Author Kimberly Ann Johnson explores this in her book The Fourth Trimester: “Exercise is a healthy stress reliever, but sometimes it is the only way that women know how to regulate their stress levels. [Pregnancy] is a great time to strengthen internal practices like meditation.”

    Yoga as a form of rest and recovery

    Embracing rest throughout each perinatal stage doesn’t mean giving up movement. Yoga connects our bodies and minds during this transitory time. While standard yoga centers on stretching, prenatal yoga emphasizes structural alignment and stability-focused work—from strengthening the pelvic floor to releasing lower back tension. It also includes breathwork and visualization techniques.

    Research indicates prenatal yoga can reduce labor pain, lower the likelihood of intervention during childbirth, and boost the birthing parent’s immune function. Additionally, studies suggest yoga enhances psychological well-being during pregnancy and postpartum by mitigating stress and improving sleep quality.

    Reframing the concept of self-care

    Whether pregnant or caring for a newborn, committing to a standard yoga practice each week may be unrealistic. Instead, reframing self-care and not fixating on a previous workout routine is crucial. Smaller but more regular practices of self-care can be as beneficial as an hour at the gym. There’s no going back after having a child; you’re creating something new.

    Supplements and strategies to reach your health goals

    There are certain fundamental steps needed to reach any goals. Most of us know these things, but reminders are sometimes necessary to get back on track.

    These essential strategies—eating a healthy diet rich in colorful produce; exercising; getting plenty of sleep; drinking pure water; reducing harmful foods like fast food, fried food, and processed food; and eliminating habits that sabotage efforts, such as smoking and excessive drinking or eating—form the foundation for other health goals.

    Improve brain and mental health

    Nutrition and lifestyle choices play a large role in brain and mental health:

    • Following the Mediterranean diet—rich in fruits, vegetables, olive oil, and whole grains, plus fish, poultry, and eggs—can reduce the risk of cognitive decline and depression.
    • Supplementing with saffron may help protect against memory loss.
    • Drinking green tea may help reduce harmful amyloid-B plaques in the brain, linked to Alzheimer’s disease.
    • Exercising improves memory, so head out for a brisk walk on your lunch break or hit the gym after work.
    • Adding mushrooms to your diet at least twice a week may help reduce cognitive decline.
    • Supplementing with vitamin D3, if deficient, may significantly improve cognitive performance.

    Boost cardiovascular health

    The journey to cardiovascular health also involves healthy diet and lifestyle habits:

    • Engaging in regular activity—moderate to vigorous aerobic activities, with at least 150 minutes per week and muscle-strengthening activities twice a week.
    • Following a Mediterranean diet is linked to a reduction in stroke risk.
    • Drinking two to three cups of green tea may prevent fat buildup in arteries.
    • Sleeping seven to nine hours nightly; insufficient sleep may increase heart disease
    • Managing stress through self-care, connecting with loved ones, practicing yoga or meditation, journaling, or engaging in
    • Eating a diet high in anthocyanins (berries, cherries, and purple cabbage) has been linked to a significant reduction in heart disease risk.
    • Supplementing with omega-3 fatty acids—including wild salmon, mackerel, flaxseeds, and walnuts—may help reduce heart disease risk.

    Live a longer, healthier life

    To extend your life, what you don’t eat is as important as what you do:

    • Engaging in caloric restriction or fasting while maintaining optimal nutrition can effectively extend your life and ward off illness.
    • Maintaining a healthy body weight and reducing excessive abdominal fat through an active lifestyle improves
    • Eating at least three servings of nuts per week has been linked to a significant reduction in mortality risk.
    • Supplementing with curcumin has been linked to improved brain, heart, and lung health, and protection against age-related diseases.
    • Drinking green tea regularly has significant links to reduced risk of cognitive decline.
    • Finding purpose in life has been shown to lower inflammation, which can affect lifespan.

    Saving soil and ocean health now and for the future

    Land and sea may seem like opposites, but the two are intricately connected. What happens on land, especially with our soils, has an impact on the health of our oceans, and it’s imperative to the well-being of all living things that both are treated carefully.

    How soil health affects the health of our planet

    “Poor agricultural practices can cause soil erosion and soil pollution,” says James Campbell, a research associate with the Research Centre for Carbon Solutions at Heriot-Watt University.

    About 33 percent of the Earth’s soil is degraded, largely due to agriculture, and more than 90 percent faces the same fate by 2050, according to the United Nations (UN) Food and Agriculture Organization. But more than just the future of food production is thrown into jeopardy by this fact. So, too, is the planet’s ability to sustain any kind of life at all.

    Soil stores carbon, helping to regulate the planet’s temperature. When it’s degraded, all that stored carbon gets released back into the atmosphere, making it one of the biggest contributors to climate change.

    The connection between soil health and our oceans

    Land and soil degradation also affects our oceans. After all, carbon dioxide (CO2) being released through activities such as tilling or clear-cutting forests to make way for food production has to go somewhere. It goes into the Earth’s other carbon sink: oceans. And when CO2 dissolves in seawater, it becomes carbonic acid, raising the acidity of the ocean.

    Ocean acidification is devastating for underwater ecosystems. Also known as “osteoporosis of the sea,” it decreases carbonate in seawater, which is used by shellfish, coral, and crustaceans to build their shells, reefs, and skeletons.

    Individual actions can affect the future

    A 2020 UN report on biodiversity and ecosystem services estimated that a quarter of all terrestrial, freshwater, and marine vertebrates and invertebrates and plants are threatened with extinction, and many of those have only decades left before they’re gone forever.

    It’s a bleak prognosis, but if we want to change course, we can start by thinking more critically about the impact of our individual actions.

    Buy local

    Shorter transportation distances generally mean less carbon dioxide is emitted into the atmosphere.

    Avoid using chemicals at home

    This includes fertilizers, insecticides, and pesticides on lawns or in gardens, which are harmful to humans, insects, birds, fish, and pets.

    Swap the lawn for native plant species

    To decrease the amount of mowing, watering, and even fertilizing required to keep your lawn lush, start switching out grass for vegetation that grows naturally where you are.

    Keep Fluffy indoors

    Cats are stealthy hunters, posing a threat to birds, small animals, and reptiles that call your yard or neighborhood home. If Fluffy is desperate to get out, dress him up in a collar with a bell to alert prey to his presence.

  • Slow down!

    Slow down!

    Slow down!

    It’s time for reflection and a fresh start

    Springtime is the perfect opportunity to start fresh by consciously pausing to rest, reflect, and recalibrate. Create space for quiet time and make the most of it. Here’s how.

    Back to basics

    Take several deep conscious breaths and reflect on your

    • energy level
    • physical health
    • emotional state
    • financial condition
    • relationship health

    Notice where you may be out of balance, depleted, or too full. This gives you a quick baseline, a reference point to guide you forward.

    Shouldn’t I be doing something?

    When we’ve been doing a lot, it can seem like there’s something off if we don’t continue to keep busy. However there’s so much to be learned when we shift focus from doing to being.

    Judy Cashmore is a movement and embodiment teacher. She sees numerous benefits to embracing the quiet of being:

    • deep restoration of our nervous system
    • sparking of creative impulses and problem-solving approaches
    • clearer perspective on ourselves and on our lives
    • space to process and release any stuck or repetitive thoughts and feelings
    • connection with the natural world by allowing ourselves our own “season” of quiet

    We’re all wired differently!

    The 20th-century analyst Carl Jung posited that people either recharge themselves in solitude (introverts) or socially (extroverts). The contrasting styles are on a continuum where each person has differing proportions of each style. Thus, we may have different levels of comfort with social stimulation and also different ways of centring and recharging.

    If you’re more introverted and yearning for downtime, yet still have family, work, or social obligations, try intentionally integrating boundaries and breathers. If, on the other hand, you’re more extroverted and yearning for social activity to continue, try reaching out to others and do something together.

    Reframing alone time

    Notice what story you tell yourself about alone time—because that story will inevitably influence your perspective. If you think there’s something wrong because you are alone right now, try reframing to encompass the notion of space for something new.

    If you’ve been spending a great deal of time alone and telling yourself it’s good because it’s solitude, consider if you’re avoiding or missing something else. You might reframe your experience as a period of isolation from which you can shift.

    Recognize that your beliefs affect your perceptions and thoughts—so if you want a different experience, change up your assumptions!

    Find the gold

    This season will transition into the next. Before it does, you have some space to give yourself a shake and begin anew. Take your time, and maybe appreciate yourself in the process. There is really no one like you!

    How to manage food allergy, intolerance, and sensitivity

    We often misuse the terms food allergy, intolerance, and sensitivity in conversation. Knowing what type of food reaction you’re experiencing is key for making appropriate dietary choices that address the underlying problem and foster overall health long term.

    Food allergy

    Food allergy is a pathological immune reaction against normally harmless proteins in foods, which can be life-threatening. This immune reaction can trigger acute symptoms in the gut, skin, respiratory tract, cardiovascular system, and neurological system.

    Common food allergens include dairy, egg, fish, shellfish, tree nuts, peanuts, soy, and wheat.

    Food intolerance

    Food intolerance is a non-immune mediated reaction arising from an insufficiency of enzymes required to break down a specific component of food. This reaction commonly causes gastrointestinal symptoms such as diarrhea.

    Common causes of food intolerance include lactose, gluten, FODMAPs (a group of short-chain carbohydrates), additives, and biogenic amines such as histamine.

    Food sensitivity

    A food sensitivity is an adverse reaction to food that is not related to food allergy, food intolerance, or celiac disease. Food sensitivities can cause digestive issues in addition to widespread symptoms such as chronic joint pain, fatigue, rash, and brain fog. If you’re dealing with chronic health concerns, it may be beneficial to investigate unidentified food sensitivities.

    Diagnosis and management

    Begin by asking your family doctor for a referral to an allergist, which will allow you to pursue allergy testing. Skin prick tests and blood tests are commonly used to identify IgE immunoglobulin mediated food allergy. Food allergy is best managed with complete avoidance and emergency medication.

    If your allergy testing comes back normal, then you might want to consider intolerance or sensitivity as the cause of your symptoms. While testing options may include hydrogen breath testing for lactose intolerance and blood testing for IgG food sensitivities, Harvard Health considers the elimination diet to be the gold standard for identifying problematic foods.

    Speak with a naturopathic doctor or nutritionist for support during an elimination diet and how to implement new dietary habits to accommodate food intolerance and sensitivity. Ask about natural supports for gut healing using minerals, amino acids, and herbs.

    Dos for dining out

    • Learn hidden sources of your food allergen (sauces, oils) and common sources of cross-contamination (deep-fried foods).
    • Choose a restaurant that uses whole, rather than processed, foods.
    • Call the restaurant ahead and ask if they have an allergy-friendly menu.
    • Tell your server about your concerns and ask for recommendations.
    • Bring reinforcements in case of allergen exposure, whether that’s an epinephrine autoinjector (EpiPen), digestive enzymes, or peppermint tea.

    Embracing new food habits

    • Google common alternatives to your favorite foods.
    • Borrow allergen-free cookbooks from the library.
    • Prep meals on Sundays for a smooth work week.
    • Involve the family in cooking dinner.
    • Challenge your friends to try new cuisines and restaurants that cater to your needs.

  • Find your path toward well-being

    Find your path toward well-being

    Purpose, power, and physical health

    Often when we begin to reflect on the metaphysical questions in life, including “what’s my purpose?” we undervalue the role of physical health in the journey. But having the healthiest body possible allows us to more easily grow and stretch in other areas of life. Here are some key focus areas to boost physical health so you can more powerfully live on purpose.

    The power of purpose

    First of all, let’s eliminate any notion that seeking out your purpose and expressing it is frivolous. American psychologist Abraham Maslow, in his famous hierarchy of needs, proposed that self-actualization is the pinnacle of a life well lived. In other words, stretching to the edges of your abilities is important for your well-being. In fact, research suggests that finding purpose can add years to your life.

    Purpose and well-being

    As you reflect on your purpose, remember that there is no single magic answer and that your purpose evolves over time. Consider each of the facets of well-being as a jumping-off point for finding your next purpose.

    Garbage in, garbage out

    One of the easiest ways to minimize physical distractions is to limit the disease-promoting toxins you expose yourself to. This includes not only harmful chemicals in foods, body care products, and home supplies but also relationships, environments, and spaces that feel poisonous.

    Pay attention to how your habitual television viewing, video games, and nights out with the gang make you feel in your body. Are you light, happy, and excited or sad, depressed, and anxious? Eliminate the stress-inducing spaces and people.

    I think, therefore I am

    The brain doesn’t benefit from the same lymphatic system that removes toxins and pathogens in the rest of your body. Instead, the brain’s “glymphatic” system rinses debris from the spaces between your brain cells. The caveat to this system is that it works 60 percent better when you’re sleeping than when you’re awake—which means sleep is a purposeful priority.

    You know it in your heart

    While your brain helps you with your lists and your decisions, the heart has traditionally been seen as the hub of perception and awareness. Research has shown there is a two-way street between emotional and spiritual well-being and heart health. Nourish your heart connection with mindfulness activities such as yoga, time in nature, and meditation, as well as regular exercise and plenty of antioxidant-rich foods.

    Liver lovin’

    Possibly the least considered yet most involved organ in your body is your liver. It plays a role in all your major life events, from digestion and elimination to circulation, detoxification, and hormone metabolism. It’s a factor in body shape, inflammation, energy levels, and mood.

    Purpose proviso

    Don’t panic if you’re struggling to demystify your purpose. Often, the path is revealed only after we start walking. Until clarity comes, focus on removing the physical health distractions. It’s a win/win.

  • How to embrace healthy aging

    How to embrace healthy aging

    How to embrace healthy aging

    Choose proactivity

    As we journey through life, it’s easy to feel overwhelmed by the myriad minor age-related ailments that seem to crop up as we get older. Many of us may accept these issues as part and parcel of the aging process. However, fostering resilience and taking preventive steps can help us manage and even prevent these ailments. Let’s explore how to address common aging-related ailments across some key areas.

    Bone and joint health

    Our bones and joints bear the brunt of our daily activities, and as we age, they require extra care. Aching joints and reduced bone density are common complaints among older adults. However, these issues can be managed and even mitigated with the right strategies.

    Aches and pains should never be dismissed as mere signs of aging, particularly if they increase in severity or if they occur quickly. They often indicate underlying issues that need attention.

    Regular exercise, tailored to individual capabilities, may improve joint flexibility and bone strength. Weight-bearing exercises, like walking, jogging, or resistance training, help maintain bone density; while stretching and flexibility exercises keep joints supple. Importantly, though, we must listen to our bodies to ensure we aren’t pushing ourselves too hard.

    Calcium and vitamin D are essential for bone health. Adequate intake of these nutrients can reduce the risk of fractures and osteoporosis.

    Hearing, eyesight, and sleep health

    Hearing loss is a common issue with aging, but it can be managed and prevented. Avoiding prolonged exposure to loud noises and using hearing protection in noisy environments are crucial steps. Regular hearing check-ups can help detect early signs of hearing loss, allowing for timely intervention

    Eyesight can deteriorate with age, leading to conditions like cataracts, glaucoma, and macular degeneration. Regular eye examinations are essential for early detection and treatment. Wearing sunglasses to protect against UV rays, maintaining a diet rich in antioxidants (like vitamins C and E), and using adequate lighting can support eye health.

    Quality sleep is fundamental to our overall health. Sleep disorders, such as insomnia or sleep apnea, often increase with age. Establishing a regular sleep routine, creating a comfortable sleep environment, and limiting caffeine and alcohol intake can promote better sleep.

    Diet and digestion

    A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats provides essential nutrients for aging bodies. Fiber is particularly important for digestive health, helping to prevent constipation and other gastrointestinal issues. Staying hydrated is equally crucial, as dehydration can exacerbate digestive problems and affect overall health.

    Probiotics can support a healthy gut microbiome, improving digestion and nutrient absorption. Digestive enzymes may also aid those experiencing difficulties in breaking down food, ensuring that nutrients are effectively utilized by the body.

    Professional support

    Taking a holistic approach to health, encompassing physical, psychological, and social well-being, is crucial for healthy aging. Regular checkups with healthcare practitioners ensure that any persistent or serious symptoms are addressed promptly.

  • Connect with nature this March

    Connect with nature this March

    Connect with nature this March

    Embrace the season and find joy

    Ask anyone what their least favorite month is and chances are March will be high on the list. Depending on what the weather throws at us, it can be more bleak than blossom, our doors still shut though we’re itching to bust them wide open. If winter feels like an annual rite of passage, then March is the final leg of it.

    Connect with nature

    How, then, do we make peace with this month? Regular connection with the natural world is one powerful strategy.

    Registered psychologist Sam Kriviak advises looking to nature as a model for being gentle with ourselves and the seasonal changes we experience in mood, energy, and productivity. “All species ebb and flow with the seasons in northern climates. The more connected we can be to nature, I think, the more we notice that our March will likely look and feel very different from our July or our October … and that’s okay!”

    Participants in a large UK study committed to some form of nature-based activity every day for a month. The result was an increase in nature connectedness, health, happiness, and conservation behaviors that lasted well past the 30 days. Spending time in nature can help foster physical health, and may even help to support our immune systems!

    Here are a few ways to foster connection in nature this season.

    Be attentive

    Simply locating ourselves in relation to Earth’s cycles can help us appreciate this time of year in a new light. Longstanding practices in your region, such as tapping of sugar maples or migratory bird counts, offer clues to the seasonal shifts happening around you.

    Do your own ancestral traditions offer a way to recognize this transitional month? And don’t forget to mark the spring equinox, either contemplatively or through a shared celebration such as a potluck, campfire, or walk with friends.

    Engage in comfort

    Direct contact with nature can be had even from a comfortable place indoors. Whether you’re eating, napping, or getting a little work done, position yourself where sunbeams are entering your home and soak them up.

    Get out there

    Nothing can perk us up quite like getting outside and imbibing the medicine of the natural world through our senses. Perhaps stroll at your kids’ pace, using an app to identify birds by their song or guessing which tree or plant you’re looking at based solely on its bark or dried seed heads.

    Use your head

    Even when the weather truly relegates us to the indoors, nature can work its magic through our imaginations. Children might enjoy drawing what all the underground life is up to this time of year: roots, worms, and microbes still slumbering or beginning to stir and wake.

    Get a jump on spring

    It’s the ideal time to begin many plants indoors, giving them a head start on the growing season. Planting seeds is an inherently optimistic act.

  • Get to the heart of circulation

    Get to the heart of circulation

    Get to the heart of circulation

    Healthy blood flow, explained

    The circulatory system is a closed loop that starts and ends with the heart. While that sounds simple enough, it’s actually a highly intricate network composed of approximately 60,000 miles of blood vessels.

    The purpose of circulation

    The body’s muscles, tissues, and organs require a continuous replenishment of oxygen, nutrients, and hormones to maintain their physiologic functions. These materials are packaged in the blood and pumped by the heart to the target tissues via blood vessels.

    Once these goods are delivered to the muscles, tissues, and organs, the blood collects waste products, such as carbon dioxide, to be eliminated from the body.

    Anatomy

    Arteries are strong, muscular blood vessels which carry oxygen-rich blood away from the heart (except for the pulmonary arteries, which carry oxygen-poor blood from the heart to the lungs).

    Capillaries  are tiny, thin-walled blood vessels responsible for the delivery of oxygen, nutrients, and hormones to the tissues, as well as the collection of carbon dioxide and waste products.

    Veins are vessels responsible for returning deoxygenated blood to the heart. Veins operate with a system of valves to ensure blood moves in one direction.

    Live circuit

    Imagine the blood vessel network as a tree. A tree’s trunk branches off into a couple large branches, which continue to divide into smaller, more numerous twigs.

    In a similar way, the left side of the heart pumps oxygen-rich blood through the aorta, which then branches off into large arteries going to different places in the body. Arteries divide into smaller arterioles as they get closer to their destination, and then end in tiny capillaries which perfuse the target tissues with blood.

    Capillaries have thin walls, which allows for the delivery of oxygen, nutrients, and hormones from the blood to the tissues, as well as the collection of carbon dioxide and waste products.

    The capillaries also begin the process of returning oxygen-poor blood to the heart. Capillaries merge into venules, which eventually converge to form larger veins. Veins deliver deoxygenated blood to the heart.

    The right side of the heart then pumps this blood to the lungs to release carbon dioxide and reoxygenate the blood via respiration. The pulmonary veins return oxygenated blood to the heart so that the circuit can begin again.

    The heart of the matter

    The heart is the key player in the circulatory system. This hollow, muscular organ is responsible for maintaining strong, rhythmic contractions that pump blood into the arteries and maintain blood pressure.

    A healthy circulatory system depends upon the proper functioning of the heart itself, comprising its electrical conduction, valve system, as well as its own blood perfusion.

    Problems may arise if the heart’s electrical signaling becomes dysregulated (e.g., arrhythmia), its valves become leaky and allow for backward blood flow (e.g., valvular insufficiency), or if the heart muscles are poorly perfused with blood (e.g., coronary artery disease).

    Poor circulation

    Circulation is compromised if there is an obstacle to delivering blood to the tissues. This obstacle might arise anywhere in the circulatory system (e.g., plaque in the coronary artery, embolism in the lungs, valve dysfunction in the veins).

    Although the extremities are commonly affected, poor circulation can present with myriad signs and symptoms all over the body. The symptom presentation depends on the tissues being affected by the lack of oxygen.

    Bear in mind that poor circulation isn’t a disease in itself but a result of an underlying condition. Share your concerns with your healthcare provider so that you receive a thorough assessment and appropriate treatment.

    Symptoms of poor circulation include

    • cold extremities
    • numbness
    • tingling
    • muscular weakness or pain while walking
    • pale or blue skin
    • swelling
    • bulging veins

    Common causes of poor circulation include

    • diabetes
    • obesity
    • smoking
    • hypertension
    • atherosclerosis
    • peripheral artery disease
    • varicose veins
    • Raynaud’s disease
    • deep vein thrombosis

    Circulation-supporting supplements

    • Curcumin
    • Ginger
    • Chinese patent medicines
    • Ginkgo biloba
    • Hawthorn
    • L-arginine

    Always check with your health care practitioner before trying a new supplement, to make sure it’s right for you.
