If you’ve spent any time scrolling through wellness blogs or chatting with friends about stress, you’ve probably heard the word “cortisol” thrown around a lot lately.
It’s been called the “stress hormone,” blamed for everything from belly fat to sleepless nights — but also praised for its role in keeping us alert and energised.
So, what’s all the fuss about cortisol? Is it really the villain some make it out to be, or does it deserve a bit more credit for all the important work it does behind the scenes?
In this blog I take a closer look at this fascinating hormone — what it does, why it matters, and how we can live in better balance with it.
Feeling tired and stressed?
What Exactly Is Cortisol?
Cortisol is a hormone produced by your adrenal glands — two small, triangular-shaped glands that sit on top of your kidneys. It’s part of your body’s endocrine system, which is responsible for producing and regulating hormones that keep things running smoothly.
Often called the “stress hormone,” cortisol helps drive your fight-or-flight response. When your brain perceives a threat (whether it’s physical danger or a mental stressor) it triggers a chain reaction that tells your adrenal glands to release cortisol. The result? A surge of energy, focus, and readiness to act.
Cortisol’s Many Jobs in the Body
Regulates energy levels: Cortisol helps your body manage how it uses carbohydrates, fats, and proteins for energy. It naturally rises in the morning to help you feel alert.
Manages the stress response: It raises blood sugar, increases blood pressure, and sharpens focus so you can handle challenges.
Reduces inflammation: Cortisol is a natural anti-inflammatory that helps keep the immune system from overreacting.
Supports sleep–wake cycles: It works with melatonin to balance your circadian rhythm — higher in the morning, lower at night.
Aids recovery and repair: After exercise, healthy cortisol levels help mobilise energy for tissue repair.
So, Why Does Cortisol Get a Bad Reputation?
Cortisol becomes a problem when it’s out of balance. Modern life is full of stress triggers — emails, traffic, notifications, deadlines — and our bodies can react as if each one is a real threat.
When levels stay elevated for too long, it can lead to:
Constant fatigue or feeling “wired but tired”
Difficulty sleeping or frequent waking
Cravings for sugary or high fat foods
Weight gain around the belly area
Mood swings, anxiety, or irritability
Frequent colds or low immunity
Trouble focusing or brain fog
Why Cortisol Is a Hot Topic Right Now
The rise of burnout culture: Constant busyness keeps stress hormones high.
Health trends & “biohacking”: There’s lots of hormone advice online — not all of it accurate.
Mental health awareness: We’re connecting the dots between emotional and physical stress.
Fitness & recovery: Overtraining can elevate cortisol; balanced movement can reduce it.
Why We Need Cortisol (Yes, Really!)
It keeps us alive: Helps regulate blood sugar, blood pressure, and energy.
It helps us handle stress: Supports focus and performance under pressure.
It controls inflammation: Acts as a “dimmer switch” for the immune system.
It helps us wake up: Morning cortisol is part of your natural get-up-and-go.
How to Keep Cortisol in Balance
You don’t need to overhaul your life — small, consistent habits make the biggest difference.
1) Prioritise Quality Sleep
Aim for 7–9 hours per night, reduce blue light before bed, and build a wind-down routine.
2) Move Your Body (But Don’t Overdo It)
Exercise helps burn off excess cortisol. Mix energising classes like Zumba and BollyX with calming options like walking, stretching, or yoga. New to fitness? Zumba Gold or Lift & Laugh are gentle, stress-friendly starts.
3) Eat Regularly and Nourishingly
Don’t skip meals. Include protein, healthy fats, and fibre to keep blood sugar — and cortisol — steady.
4) Make Time to Relax
Try deep breathing, mindfulness, music, or a few minutes of quiet. Laughter and dancing are natural stress relievers.
5) Get Morning Sunlight
Natural light early in the day helps reset your body clock and supports a healthy cortisol rhythm.
6) Go Easy on Caffeine and Sugar
Both can spike cortisol — especially on an empty stomach. Enjoy them mindfully.
7) Practice Gratitude and Joy
Positive emotions help regulate stress hormones. Connect with others, notice small wins, and keep joy on the agenda.
The Takeaway: It’s All About Balance
Cortisol isn’t something to fear — it’s something to understand. Too little, and you’ll feel drained and sluggish. Too much, and you’ll feel tense and wired. The goal is balance.
By moving your body, resting properly, nourishing yourself, and finding moments of joy and gratitude,, you can help your cortisol levels settle into a healthy rhythm.
When cortisol is balanced, you feel balanced too.
