Cortisol and stress: what it does to your body

Cortisol is often called "the stress hormone", but it does much more than that. In this article you'll read how your daily cortisol rhythm works, what prolonged busy periods do to it, and which daily habits help you bring rhythm back into your day.

Cortisol en stress: wat het met je lichaam doet

What is cortisol?

Cortisol is a hormone made by your adrenal glands, on a signal from your brain. It plays a role in your blood sugar, blood pressure, immune system and your sleep-wake rhythm, among other things.

Cortisol follows a fixed daily rhythm: highest shortly after waking up, so you get going, then gradually lower, and lowest around bedtime, so you can sleep.

Short-term versus long-term stress

Short-term stress, such as a deadline or a difficult conversation, is normal: your body gears up for a moment and then back down. It gets harder when busy periods last for months and recovery structurally gets too little room. Then your daily rhythm can get disrupted: you struggle to get going in the morning and feel restless in the evening.

How to bring rhythm back into your day

  • Fixed times: get up and go to bed at around the same time, weekends included.
  • Morning daylight: a short walk outside helps your daily rhythm get going.
  • Gentle exercise: walking, cycling, yoga or light strength training. In busy periods it doesn't need to be intense.
  • Regular meals: with protein, fibre and healthy fats, and without going too long without eating.
  • Caffeine in moderation: no more than 400 mg a day (about 4 cups of coffee) and preferably not after 2 pm.
  • A daily moment of rest: 10 to 20 minutes of breathing exercises, meditation, journaling or a walk in nature.

Sleep is the foundation. How to build a fixed evening routine is explained in Sleep and stress: how to break the cycle.

Nutrition and magnesium

A varied diet remains the starting point. Magnesium is a mineral worth paying attention to: it is found in nuts, seeds, pulses, wholegrain products and green vegetables. It is officially established that magnesium contributes to normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue.

Frequently asked questions about cortisol and stress

In summary

Cortisol is not the enemy

Cortisol is an essential hormone with its own daily rhythm. Only when busy periods last long and recovery gets too little room does that rhythm get disrupted. Recovery starts with the basics: sleep, exercise, regular meals and fixed moments of rest. A food supplement can be an addition, but does not replace those basics.

Want to start with a fixed moment for yourself? Try Plantforce Vegan Magnesium or choose the value pack of 3 tubs.
