Most of us crave sugar or salty foods when we are stressed. Some have been stress baking during these unprecedented times so there is some merit to ‘stressed’ being ‘desserts’ backward. Some are probably loving this period working from home and sleeping + relaxing while others are feeling the financial stress, emotional stress, anxiety/depressed mood, stress of homeschooling kids and the uncertainty of not knowing when to go back to work/school.
When we are exposed to stress – any kind such as physiological stress like inflammation, a surgery’s toll on the body, or emotional stress – the hypothalamus-pituitary-adrenal (HPA) axis in our bodies gets activated. The hypothalamus and pituitary organs are located in the brain while the adrenal glands sit on top of our kidneys (the hat to the kidney). This HPA axis is responsible for regulating our reaction to stress through feedback mechanisms and plays a role in our digestion, immune function, sleep, mood, weight gain, and other hormonal imbalances.
Under normal circumstances, we need to be able to produce a sufficient level of cortisol to help us get through the day but the production gets increased during times of stress. It is protective to regulate our immune system, inflammation, and other body processes. Normally, cortisol is highest in the first hour or two upon waking to give us the energy to get out of bed and then gradually declines over the course of the day and is the lowest at night to help us go to sleep.
The three stages to the stress response has been coined “The General Adaptation Syndrome” by Dr. Hans Selye, MD. After the initial exposure to a stressful situation, we enter the ‘alarm’ phase. This is the immediate activation of our sympathetic or “fright or flight” nervous system releasing adrenaline – our heart rates goes up, blood pressure goes up, and the body is preparing to flee from the stressful situation. The anxiety may kick in and that initial reduced "on-edge" response to the stressor feeling occurs. After a few minutes, the brain tells the adrenal glands to produce cortisol (glucocorticoid – blood sugar hormone), aldosterone (sodium and water balance hormone), and DHEA. Over time with chronic elevation of cortisol, DHEA may decrease resulting in a drop in testosterone.
The second stage is the resistance phase. This is when your body adapts to the stressor with elevated cortisol and the adrenaline levels wll decrease. The body is coping with the stressor on hand.
The third stage is known as the exhaustion phase when cortisol levels cannot keep up due to chronic stress or an ‘exhausted’ firing of the HPA axis and levels drop – the adaptation or coping phase is lost.
Right now many of us during these crazy times are probably moving into the resistance phase finding we are coping with the situation. This is the time to take action and work on lowering your stress, calming the mind before we exhaust the production of cortisol, and come out of this feeling depleted and exhausted.
General Adaptation Syndrome and the symptoms at each stage
Melatonin and Sleep
Immune and Inflammation
- Have a regular bedtime routine because a good night’s sleep can regulate cortisol levels
- Reduce screens and blue light 2 hours before bed to keep melatonin production optimal
- Don’t have caffeine later in the day so you can get a good night’s sleep
- Meditation, light exercise, yoga, dance to calm the mind can help modulate your cortisol levels. Intense exercise can raise cortisol levels
- Wake up to bright light or sunlight to promote your cortisol awakening response and give you great energy in the morning
- Anything you need right now to lower your stress levels and find calm in the storm
- Try not to eat too much sugar as it will affect your blood sugar regulation which will in turn, affect your cortisol levels.
- Eating healthy fats and protein and more fibrous carbohydrates can help in regulating blood sugar levels and thus insulin levels
- Take adaptogens (adrenal modulating herbs for modulating cortisol) after consulting with a naturopathic doctor in your area

3 Thoughts on “Cortisol – It’s Lowdown and Why Stressed = Desserts”
I’m amazed, I must say. Rarely do I come across a blog that’s equally educative and engaging, and let me tell you, you have hit the nail on the head. The issue is something that not enough folks are speaking intelligently about. Now i’m very happy I found this during my search for something concerning this.
