Being under prolonged stress is not easy on the body or the mind. Cortisol, the body’s main stress hormone, plays a big role, affecting mood, decision-making, and even cravings.
When someone walks through the doors of our treatment centre, they often carry more than just the challenges of substance use. Many of our clients arrive exhausted from a constant, invisible battle with stress that they have been fighting for years.
In fact, when cortisol levels are out of balance, it can contribute to both the start and continuation of substance use. Understanding the role cortisol plays can help us see why addiction isn’t just a matter of willpower.
What is Cortisol?
Cortisol is produced in our bodies by the adrenal glands and is crucial for keeping us in balance. It helps regulate metabolism, blood pressure, and immune function.
When we face an imminent deadline, a job interview, or a sudden crisis, our body boosts our attention and focus with this stress hormone, preparing us to act. But when stress is a constant in our lives, our levels of cortisol don’t get a break either. Research shows that having constant high cortisol can lead to anxiety, sleep issues, irritability, and even physical health problems.
We often see clients who, for years, have been living in this heightened state of alert. Every stressful moment triggers cravings, and every disruption in routine feels overwhelming. Cortisol is always there, keeping the body on edge and amplifying both stress and the desire to use substances as a way to cope. Over time, this chronic hormonal imbalance can make it harder to regulate emotions, manage triggers, and sustain recovery.
The Cortisol-Addiction Cycle
For many, stress and addiction form a vicious circle. High cortisol levels can make substances feel like a necessary escape. Yet, substance use further disrupts cortisol rhythms, deepening stress and creating a feedback loop that can feel impossible to break.
An individual may start using alcohol or drugs as a way to self-soothe stress. However, over time, their body’s natural stress-response system becomes dysregulated. They may not even realize it. Stress, cravings, and substance use begin to merge into a vicious cycle.
How We Support Our Clients
At our centres, understanding cortisol isn’t just theoretical—it informs the way we structure our programs at every level, focusing on holistic, evidence-based strategies that help clients regain control over their bodies, their minds, and their recovery.
Mindfulness
Mindfulness is heavily incorporated into every aspect of our program. Simple practices—like guided meditation, deep breathing, and even massage—help clients step out of the constant “fight-or-flight” mode. We’ve seen clients who, after just a few sessions, notice their minds quieting for the first time in years. That moment of relief isn’t small—it’s transformational, and critical in rebalancing their stress-related hormones.
Physical Activity
Exercise is another cornerstone. Whether it’s yoga, walking in nature, or light strength training, movement helps regulate cortisol naturally. Clients often remark how a morning walk or a group yoga session leaves them calmer and more in control of their cravings. Our in-house gym and swimming pool, along with our regularly scheduled sports and outings, bring physical wellness within reach.
Nutrition and Sleep Hygiene
Both nutrition and sleep are often overlooked in discussions about recovery, but they may very well be the two most important pillars of regulating your system. We work with clients to restore rhythms that have been disrupted for years. We offer balanced meals, regular sleep schedules, and education with our on-site Nutritionist and Hormonal Health Specialist about the impact of diet in relation to stress. Even small changes, like a consistent bedtime or a protein-rich breakfast, can have noticeable effects on mood and cravings.
Cognitive Behavioural Therapy (CBT)
Our therapy sessions help clients identify the thought patterns that fuel stress and substance use. Through CBT, clients learn to challenge these thoughts and adopt coping mechanisms that reduce cortisol-triggering anxiety. Many clients describe this as “learning to pause before reacting,” a skill that often feels impossible outside of treatment.
Social Support
Lastly, we cultivate a supportive environment. Peer groups, family support services, and one-on-one counselling all provide the connection our clients need. Strong social bonds don’t just improve mental health; they directly lower cortisol levels and reinforce the tools learned in therapy.
