Cortisol, Stress and Balance: How to Support Your Body When Life Feels Too Much
Our modern world can definitely get a bit crazy - I am sure I am not alone in thinking this!!! We are constantly plugged in and switched on with work pressures, family responsibilities, financial concerns, health issues and daily busyness, all of which add up and leave us feeling overwhelmed, overstimulated and burnt out.
In short bursts, stress helps you respond and perform and is even anti-inflammatory and protective! However, when stress becomes constant, the hormone cortisol can remain elevated and begin to significantly impact mood, sleep, hormones, immunity, metabolism, and many other aspects of health. As with everything in life a bit is ok but when we get too much of anything - something slides!!
At Earthflow Health Naturopathy, I help people understand the relationship between cortisol and stress on a deeper level and how this impacts our whole being by finding natural solutions to restore balance and resilience, harmonising your mind, body, spirit as everything is connected.
What is cortisol, and why it matters
Cortisol is produced by the adrenal glands and is central to the body’s response to challenge. Helping the body to mobilise energy, maintain blood pressure, regulate inflammation and support the sleep-wake cycle.
Cortisol is not the enemy, as many people are led to believe. Cortisol is actually vital and in healthy rhythms, it supports survival, focus and recovery. The issue arises when cortisol remains elevated for prolonged periods. That is when we start to see physical and emotional consequences that can have debilitating consequences.
So there are benefits and problems with cortisol.
Cortisol benefits the body in numerous ways. It helps you wake up with focus in the morning, provides extra energy when you need to respond quickly, and tempers inflammation during short-term injuries or infections.
However, chronically high cortisol can have negative effects. Persistent elevations are linked to sleep disruption, mood changes, lowered immunity, increased central fat storage, and disturbances in blood sugar regulation as cortisol increases blood sugar by triggering the liver to produce more glucose. This is called the “fight or flight “response.
Modern life can keep the stress system switched on and cause these problems to accumulate, leading to systemic negative effects, such as blood sugar dysregulation, insulin resistance, chronic inflammation, obesity and cardiovascular disease.
Recognising high cortisol: common symptoms
Many people live with elevated cortisol without realising it and common high cortisol symptoms include:
Feeling wired but exhausted
Trouble falling or staying asleep
Sugar or carbohydrate cravings and stress eating
Weight gain around the belly and trunk
Heightened anxiety or mood swings
Low libido and irregular menstrual cycles
More frequent infections or slow recovery from illness
If you notice several of these signs, it is definitely worth exploring how stress is affecting you and how implementing natural strategies can significantly improve your wellbeing and resilience. I love to help people find calm in this modern world. I love to support nervous systems, it is so important to soothe the nervous system before anything!
So how does cortisol link to weight gain?
Cortisol and weight gain are closely related for several reasons. Cortisol signals the body to preserve energy and promotes fat storage, especially in the abdominal area. At the same time, high cortisol increases cravings for high-carbohydrate, energy-dense foods. Our bodies think we are in “battle mode” and this activation of blood glucose is constantly turned on.
This pattern encourages stress eating and fluctuating blood sugar levels that further stimulate cortisol. Cortisol also impacts our hormones, which help regulate our metabolism and moods.
Working to reduce cortisol levels naturally through a targeted treatment plan and care can significantly help alleviate sugar cravings, supporting sustainable weight management and get you sleeping better!! Again one of the first things I like to focus on.
The wide-ranging effects of stress on the body
Stress impacts our whole system, mind, body, spirit. Here are some key ways chronic stress and elevated cortisol can show up in the body:
Nervous system and mental health
Chronic stress keeps the sympathetic nervous system more active than is healthy. We need to be able to switch this off!! Over time, this leads to symptoms of increased anxiety, reduced concentration and cognitive abilities and a general sense of constantly being on the edge.
Our nervous systems are in hyper alert mode, and this dysregulated cortisol has far-reaching effects across the body, including mood disorders and persistent anxiety, greatly impacting your daily life and function. Research shows complex, bidirectional links between cortisol, stress and psychiatric symptoms.
Digestive and metabolic systems
Stress can significantly slow digestion or in some cases, accelerate food transit through the gut, disrupting the natural balance of gut microbiota. This can lead to bloating, reflux, abdominal discomfort, and altered bowel habits such as diarrhoea or constipation. I think most of us have at one time expereinced a dodgy tummy when we are nervous! Elevated cortisol levels also affect blood sugar regulation and appetite hormones, increasing cravings for high-sugar or high-fat foods and over time, raising the risk of insulin resistance and metabolic dysfunction.
Chronic stress can therefore contribute not only to gastrointestinal symptoms but also to wider cardiometabolic consequences. Recent reviews in metabolic medicine highlight cortisol’s central role in shaping cardiometabolic health, influencing weight distribution, fat storage and obesity risk, while also affecting inflammatory pathways and energy metabolism.
Immune system and inflammation
Short-term cortisol helps regulate inflammation. But long-term stress can create immune dysregulation and a tendency to chronic low-grade inflammation and oxidative stress. This can underlie many chronic illnesses and make recovery slower.
Recent reviews in endocrinology and immunology highlight the complex interactions between cortisol and immune processes, as well as cortisol's influence on oxidative stress pathways, in the context of chronic disease.
Cardiovascular health
Sustained stress and altered cortisol patterns have a significant impact on the cardiovascular system. Chronic elevation of cortisol can lead to increased blood pressure, a higher heart rate and vasoconstriction, thereby placing ongoing strain on the heart and vascular system. Over time, this heightened cardiovascular load can contribute to atherosclerosis, arterial stiffness and other forms of vascular dysfunction.
Additionally, high cortisol levels influence lipid metabolism and fat distribution, often leading to increased abdominal fat, which in turn further elevates cardiometabolic risk. Chronic stress can also exacerbate insulin resistance, increase inflammatory markers and trigger oxidative stress, all of which place additional strain on the cardiovascular system.
Over many years, these combined effects contribute to higher risks of heart disease, stroke, and metabolic syndrome. Clinicians and researchers are exploring how dysregulated cortisol contributes to long-term heart disease risk.
Stress and the workplace: signs of burnout
Workplace stress is a major trigger for chronic cortisol activation. Our modern world is often not in alignment with the needs of our nervous system. Countless phone calls, hundreds of emails, constant messages incoming and a never-ending workload can make some of us feel despair. Add workplace clashes, where some individuals experience or feel unseen, unheard, and undervalued and you have a recipe for stress and burnout.
Signs that stress at work is becoming damaging include:
Emotional exhaustion and loss of motivation
Reduced ability to concentrate and make decisions
A sense of detachment or cynicism about work
Stress that filters through to other areas of your life
Sleep problems and persistent tiredness
Recurrent infections or persistent physical complaints
Depression, anxiety and low mood.
These feelings are common, and you are not alone. I have seen the stress that not being happy in the workplace can cause a client and while it is not always easy to jump ship and leave, we can look after our nervous system as best we can while in a difficult situation and the good news is, that there is some wonderful support available that can help you manage and cope significantly better. Even if you can’t change your environment, you can definitely change your inner one.
How stress increases nutrient needs
When you are stressed, your body chews through so more of certain vitamins and minerals! With so many Australians not getting close to eating their daily RDI of whole grains, veggies and fruit, this means that under chronic stress, you can become functionally low in nutrients that help the nervous system and adrenal function. Key nutrients that are used up more quickly when stressed include vitamin C, B vitamins (especially B5 and B6), magnesium and zinc.
Replenishing these nutrients through whole foods, targeted supplementation, and lifestyle support is often part of my naturopathic plans for restoring resilience and can have a profoundly positive impact on your daily life. Alongside some beautiful nourishing teas!
Gentle Herbal Supports for Stress
There are so many beautiful nervines and adaptogenic herbs that can support the nervous system through periods of stress, and I use quite a few of these regularly in clinic.
Chamomile is the classic starting point for a reason, gentle, safe for pretty much everyone, and honestly just a lovely ritual to end the day with a warm cup in hand.
Lemon balm has a similar calming effect but with a slightly uplifting quality, which I tend to reach for with clients who describe their stress as more low mood and flat than wired and anxious.
I love these herbs and use them everyday for myself, family and clients!!
Milky oats (oat straw, not the porridge kind!) is one I love for genuine nervous system exhaustion, think burnout rather than a stressful week, it's more of a slow-build nourishing tonic than a quick fix.
Lavender works beautifully for the physical tension side of stress, whether that's as a tea, in a diffuser, or in the bath before bed.
Passionflower and Motherwort are both a bit stronger and are often what I turn to when someone's dealing with racing thoughts or that wired-but-tired feeling at night, while skullcap is particularly good where stress is showing up as tension headaches or a jaw that won't unclench.
How These Herbs Work
Most of these work by gently supporting the GABA system, the same calming pathway in the brain that helps switch the nervous system out of fight-or-flight, without the grogginess or dependency risk you can get with pharmaceutical options. That's part of why I love working with them: they're supportive rather than sedating.
Using Herbal Supports Safely
A gentle reminder here that "natural" doesn't automatically mean "no interactions" some of these herbs can interact with medications, particularly anything for anxiety, sleep, or blood pressure, so please check with a qualified practitioner (me or your GP!) before starting anything new, especially if you're pregnant, breastfeeding, or already on medication. Super important.
Also good to note that some people are a bit senstive to herbal plant families and this can show up in skin rashes, digestive or respiratory issues and more. It is just woth noting but I do not see it commonly.
Nutrients for Reducing Stress
Alongside herbs, I always look at nutrient status too, magnesium, B vitamins (especially B5 and B6), vitamin C and zinc all get used up faster when you're under chronic stress, and a lot of us simply aren't getting enough through diet alone to keep up with the demand. Real food first where possible, with targeted supplementation where it's genuinely needed
Natural strategies to reduce cortisol levels
Small, consistent habits often make the biggest difference. Here are practical, evidence-informed strategies:
Meditation and breathing
Meditation, even in short daily sessions, consistently shows benefits for stress reactivity and wellbeing. Mindful breathing practices lower heart rate and help the body move into a parasympathetic state – which is our rest and digest mode. Begin with five to ten minutes daily and build gradually.
Gentle exercise and outdoor time
Moderate movement is restorative. Gentle exercises, such as walking, restorative yoga, or tai chi, help regulate cortisol levels without creating additional stress. Going outside is especially powerful. Walking, listening to the birds, breathing fresh air, and spending time in nature have measurable calming effects on the nervous system, helping cortisol return to healthier levels. I remember one client who worked from home messenging me to say how great she felt just by taking 15 mins out of her day to go for a walk around the block and another who works in the middle of a big city saying no matter the weather, she takes the lift down at lunch time to get outside and find somewhere to eat her lunch. Your brain resets, you get some fresh air and away fropm artificial lighting and temperatures.
Sleep and routine
Prioritise consistent sleep patterns. Poor sleep disrupts cortisol rhythms; we need low cortisol at night in order to produce melatonin – our sleep hormone. Consistent bed and wake-up times, as well as calming evening rituals, are important. Small changes, such as turning off screens earlier and establishing a relaxing pre-sleep routine, are highly effective. Our brains dont want bright lights beaming in to them at bedtime, the funny instagram reels can wait till the next day!
Nourish the body consistently
Regular meals with protein, healthy fats and fibre help stabilise blood sugar and avoid the cortisol spikes associated with hypoglycaemia and stress eating. Avoiding excessive caffeine and refined sugars supports a steadier mood and energy. Nothing wrong with a lovely cup of coffee or two but try to limit it to before lunch only.
Social connection and talking therapies
There is so much postive research on social connection!! Talking to someone, whether a friend, counsellor or naturopath, helps process stress and reduces the sense of being alone with problems. Therapeutic conversations can change the way stress is perceived and reduce physiological reactivity, greatly impacting your health in a positive way.
Addressing stress eating
Stress eating is a common response to elevated cortisol, I mean a good few chunks of chocolate can just hit the spot right and while cravings for sweet or starchy foods can briefly calm the nervous system, they also reinforce blood sugar swings and further cortisol release (dammit!) . Strategies to manage stress eating include regular nourishing meals, mindful eating practices, addressing underlying emotional triggers and introducing calming rituals to replace food as the first response to distress. Little note, there is nothing wrong with a little treat if you are generally eating well and we absolutely do not have to strive for perfection, there is no such thing.
Oxidative stress and the long-term effects of stress on the body
Chronic stress doesn't just affect your mood and your gut, it ages you at a cellular level too. All that stress creates free radicals, which cause what's called oxidative stress, basically wear and tear on your cells that adds up over time and feeds into inflammation. It sounds a bit doom and gloom, but the fix is genuinely simple: antioxidant-rich food, decent sleep, and a lifestyle that gives your body a chance to recover. Just think beautiful colourful fresh foods and you are on the right track!!
When to seek professional help
If you are noticing several signs of burnout, ongoing anxiety, mood imbalances, rapid weight changes, persistent poor sleep, or simply feeling unable to cope, please reach out for support. You do not need to manage this alone.
A doctor can assess your mental health and, if needed, refer you to a qualified therapist or mental health specialist who can provide emotional and psychological support. Early intervention makes a real difference and helps prevent symptoms from becoming more entrenched.
A naturopath can work alongside your healthcare team to assess your diet, lifestyle, sleep, stress levels and nutrient status. Together, you can explore gentle ways to reduce cortisol levels, calm your nervous system, balance your hormones and blood sugar levels and cultivate long-term resilience. This may include targeted nutritional guidance, herbal medicine, pathology and practical lifestyle tools and adjustments tailored to your individual needs.
Working with qualified practitioners ensures you have the right combination of medical care, emotional support, and holistic strategies. Each plays a valuable role in helping you recover balance and feel like yourself again
