Like most critical aspects of health, stress can be a double-edged sword. It’s necessary for physical and emotional growth, and we all know that what doesn’t kill you makes you stronger. However, too much stress can do far more damage than even a poor diet or a sedentary lifestyle. The trick seems to be embracing the right kinds of stress in the right doses, and under those conditions, it can be a catalyst for improved strength and resilience.

​Today for the second instalment of our Health Fundamental series, NBT coaches Megan Hall and Clay Higgins are examining stress and hormesis. They talk about simple biomarkers to help you measure your current allostatic load and then they discuss simple, practical things anyone can do to better manage emotional stress. They also discuss how to use hormesis - intentional and measured amounts of stressors like temperature, exercise, diet, and breathing, to boost your body's functioning while becoming better adapted and stronger.
