The basics
What is stress?
Stress is your body's natural response to challenge or danger. It can be physical, emotional or environmental. Short-term stress can be helpful — but when stress is constant, it can take a toll on your health and wellbeing.
What is cortisol?
Cortisol is your primary stress hormone, produced by your adrenal glands. It helps regulate energy, blood sugar, blood pressure and inflammation. It follows a natural daily rhythm: high in the morning, low at night.
When stress is constant, cortisol can stay elevated. This disrupts balance in your body and can contribute to fatigue, weight gain, mood changes and long-term health issues.
How chronic stress & cortisol affect your health
Mood & mental health
High cortisol can increase anxiety, irritability, low mood and overwhelm. It affects neurotransmitters like serotonin and dopamine.
Blood glucose
Cortisol raises blood glucose to provide quick energy. Chronic elevation can lead to insulin resistance and blood sugar imbalances.
Insulin & fat storage
High cortisol makes cells less sensitive to insulin, increasing fat storage (especially around the abdomen).
Digestion
Stress slows digestion, reduces stomach acid and enzyme production, and can trigger IBS, bloating and reflux.
Sleep
Elevated cortisol at night makes it harder to fall asleep and reduces deep, restorative sleep.
Immunity
Chronic stress can weaken your immune system, making you more prone to infections and slower recovery.
Inflammation
High cortisol dysregulates inflammation, which can contribute to pain, autoimmune issues and chronic disease.
Heart health
Long-term stress can increase blood pressure, cholesterol and risk of heart disease.
Your body is designed to adapt and heal. With the right tools and daily habits, you can lower stress, balance cortisol and support your long-term health.

Nourish your body to manage stress
Balance blood sugar
Eat regular, balanced meals with protein, healthy fats, fibre and complex carbs to stabilise blood sugar and support energy.
Eat nutrient-dense foods
Focus on whole foods rich in magnesium, B vitamins, vitamin C, omega-3s and antioxidants to support your stress response.
Stay hydrated
Even mild dehydration can increase cortisol levels and impact mood, focus and digestion.
Support your gut
A healthy gut helps regulate mood, immunity and stress hormone balance through the gut–brain connection.
Key nutrients for stress support
- Magnesium — supports relaxation, sleep and muscle recovery
- B vitamins — support energy, nervous system and mood
- Omega-3 fats — reduce inflammation and support brain health
- Vitamin C — helps regulate cortisol and supports immunity
- Adaptogenic herbs — such as ashwagandha, rhodiola, holy basil
