The science of stress, and how to beat it
We tend to think about improving our physical fitness in terms of diet and exercise alone. But our state of mind can have a huge impact on our bodies. Stress can undermine our best efforts, no matter how much CrossFit and kale we consume.
Before you get stressed about, well, being stressed, let’s take a moment to understand where it comes from and how it works.
Why does stress affect the body?
Researchers at Carnegie Mellon have tied mental stress’ effect on the body to a hormone called cortisol. Cortisol is a natural defense mechanism, giving us a boost of energy whenever we are scared or anxious.3 Back in the old days, it came to the rescue when we were being chased by a lion, tiger, or anything else that sent us running for the hills.
Fast forward to today where lions have been replaced by deadlines, and tigers by snarling bosses. The stress is constant and confusing. It sends our brain mixed signals, which releases too much cortisol. When our systems are overwhelmed with it, we lose the ability to regulate inflammation.4
What is stress doing to us?
We all know that stress can take a toll on our cardiovascular system. However, increased inflammation allows stress to affect us from head to toe.5

How we can reduce stress
Unfortunately, there’s no magic cure for stress. At least not yet. But there are some effective meditation and mindfulness measures you can take to help keep it under control.
In 2017, US scientists conducted an eight-week course of meditation and mindfulness training
which resulted in participants experiencing a 15% reduction in inflammatory molecules and stress hormones.6
Another study took participants on an intensive, three-month mindfulness retreat where researchers measured cortisol levels, before and afterward. Results were conclusive – those who exhibited an improved understanding of mindfulness showed a noticeable decrease in cortisol.7
