The Science of Stress!


100 ways to keep up on your exercise routine.


Learn about two stress hormones:
Adrenaline and Cortisol.

This stress video from National Geographic will share with you a scientific overview of the body's stress response system involving the stress hormones known as adrenaline and cortisol.

Understanding the link between cortisol and stress is a particularly compelling subject in the study of the science of stress because there can be some fairly major consequences, physically, if this stress hormone is not managed correctly.

When the body is exposed to a stressful experience (mental or physical), it begins to release the stress hormones, adrenaline and cortisol, allowing you to deal with the situation.

Adrenaline helps improve our speed and force, making us more capable of reacting/responding to the stressor, and cortisol provides the energy burst needed to support that extra speed and force.

The video explains that when the stress is physical, the cortisol burst is used up as the body burns energy, but when the stress is mental, the body cannot eliminate the hormone as easily.

Left unchecked over a long period of time, a buildup of cortisol can deplete bone density and cause other chronic diseases.

The basic message of this presentation is that, if you are going to live a life filled with mental stress challenges, then you must have a healthy and rigorous exercise routine in order to eliminate all the cortisol produced in your body.
