Imagine a day where you work hard, push yourself, sacrifice your time and energy, but in the evening... silence. No applause, no gratitude. When no one acknowledges your efforts—whether at work, at home, or with those closest to you—tension builds up, often accompanied by a sense of inner disappointment. In such cases, cortisol, the stress hormone, becomes your "silent companion," lingering even when all is quiet.
How Does Cortisol Affect the Body?
Cortisol is produced in the adrenal glands as the body’s response to stress, functioning like a natural protective mechanism. Typically, cortisol levels are higher during the day to keep us energized and gradually decrease toward evening, allowing the body to relax and prepare for sleep. However, when stress is prolonged, cortisol levels remain high, which can significantly impact your health:
Disrupts the immune system – making you more susceptible to infections and colds.
Weakens muscles – the body starts to break down muscle tissue as an energy source.
Raises blood pressure and promotes weight gain – particularly around the abdomen.
Impairs memory and concentration – making it harder to focus and more prone to forgetfulness.
Cortisol and Neurons: What Happens in the Brain?
Cortisol doesn’t just make us feel alert and focused; it also directly affects our brain. It binds to receptors on neurons in various brain regions, including the hippocampus and amygdala—areas linked to memory, emotions, and decision-making. Short-term cortisol exposure can enhance neuronal plasticity, but long-term exposure weakens neuronal resilience, potentially impairing memory and learning processes, and in some cases, leading to neurodegeneration.
Moreover, cortisol impacts mood-regulating neurotransmitters like dopamine and serotonin, explaining why chronic stress and high cortisol levels are often associated with depression and anxiety disorders.
Alcohol – The Illusion of Relaxation
It’s common to reach for a glass of wine as a way to unwind. While this may create a temporary sense of calm, alcohol disrupts the natural sleep cycle, causing you to wake up feeling even more tired. Alcohol’s effects on the brain may provide short-lived relief, but over time, it spikes cortisol, degrades sleep quality, and worsens fatigue.
Tip: If you’re craving a glass of wine, it’s best to have it before 5 p.m. This way, your body can return to a calmer state by evening, and cortisol won’t interfere with your sleep.
How to Lower Cortisol Levels?
Persistent cortisol exposure can be harmful, so it’s essential to find ways to manage it. Here are some recommendations:
Talk about your feelings – Openness helps reduce the emotional load when you feel unappreciated.
Acknowledge your efforts – Even if no one notices, recognize your accomplishments. This fosters a "healthy ego" and reduces stress.
Choose relaxation techniques – Meditation, breathing exercises, and yoga are excellent for lowering cortisol levels.
Engage in physical activity – A short walk or workout not only reduces cortisol but also strengthens the body.
Establish a calming sleep routine – Quality sleep helps your body recover, so avoid alcohol and stick to relaxing rituals before bed.
Cortisol is a vital hormone in the body’s stress response, but its impact needs careful management. A balanced approach to relaxation and selecting the right ways to unwind can help prevent excess cortisol and support a good night’s sleep and overall well-being.
