Cortisol Isn't the Enemy: How Nutrition, Stress & Recovery Work Together
When you hear the word cortisol, what comes to mind? Stress? Hormonal imbalance? Something you need to lower?
Cortisol has developed a reputation as the bad guy in conversations about health and wellness. But as Megan Berner, Registered Dietitian at Fitness Lying Down, explains in Episode 115 of Nourish to Flourish, cortisol isn't inherently bad. In fact, it's an important part of how our bodies respond to challenges.
The real issue isn't having a stress response. It's experiencing stress repeatedly without giving our bodies adequate opportunities to recover.
What Is Cortisol and Why Does Your Body Need It?
Cortisol is a hormone involved in your body's stress response. Imagine walking through a haunted house when someone suddenly jumps out at you. Your heart starts racing, your blood pressure increases, your senses become sharper, and your body makes more glucose available for quick energy.
These changes help prepare you to respond to a potential threat. That response is useful, not something we need to eliminate.
Problems can arise when stressors keep coming and recovery becomes an afterthought.
Stress Isn't Always What You Think It Is
When we think about stress, we often picture deadlines, demanding schedules, or difficult situations. But your body also responds to physical stressors.
Some common stressors include:
- Inadequate sleep
- Not eating enough to support your body's needs
- Illness and inflammation
- Physical demands without sufficient recovery
- The ongoing mental load of everyday life
One of Megan's important reminders is that we can become so accustomed to operating under stress that we don't always recognize it. Even when we don't consciously feel stressed, our bodies may still be responding to ongoing demands.
How Nutrition Supports Stress Management and Recovery
Nutrition is an important part of supporting the body's ability to manage stress. When we're not eating enough or getting a variety of nutrients, inadequate nourishment can become another physical stressor.
Our bodies rely on nutrients for numerous metabolic processes, including those involved in hormone metabolism. The liver and kidneys play important roles in processing and clearing hormones, including cortisol.
As Megan puts it, with hormones we have to make them, use them, and then lose them.
Eating adequately and consuming a variety of nutrient-rich foods helps support these normal processes. But nutrition is only one piece of the puzzle.
Why Sleep, Movement, and Recovery Matter
At Fitness Lying Down, we regularly emphasize the importance of recovery when it comes to strength training. But recovery isn't just for your muscles. It's also important when managing the physical and psychological demands of life.
Supporting recovery may include prioritizing adequate sleep, eating consistently, incorporating appropriate movement, and making time for relaxation.
The goal isn't to remove every stressor from your life. That's rarely realistic. Instead, it's to identify what you can manage and give your body the support it needs to recover.
Can Supplements Help Lower Cortisol?
You've probably seen products marketed to lower cortisol or support the nervous system. Certain nutrients, including B vitamins, are involved in normal metabolic and nervous system functions. Supplements such as ashwagandha have also been studied for their potential effects on stress.
However, supplement research varies, and these products aren't a substitute for adequate nutrition, sleep, and recovery. Supplements may also have side effects or medication interactions, so discuss them with a qualified healthcare professional before using them.
Megan's central reminder is simple: You can't out-supplement your physiology.
Rather than searching for a magic pill, focus first on the everyday habits that support your body's ability to manage stress.
Three Questions to Ask About Your Stress
Megan encourages us to approach stress management by asking three questions:
- What is triggering my stress response? Identify the physical or psychological demands that may be contributing.
- How can I reduce or manage those triggers? Consider what can realistically change, even if you can't eliminate the stressor entirely.
- How can I better support recovery? Look at your nutrition, sleep, movement, relaxation, and opportunities to recharge.
These questions can help shift the focus away from quick fixes and toward sustainable habits.
