4. Two Types of Stress

Two Types of Stress

This lesson separates the effects of stress into two categories. Short-term stress caused by a single event or a temporary situation, and ongoing or chronic stress. The effects of short-term stress are less serious as a rule and so easier to deal with.

When stress becomes longer-term and the symptoms become chronic (high blood pressure, heart disease, it has a more serious impact and the effects can be harder to correct.

Other ways of explaining the Rest-Activity Cycle

You'l hear the rest-activity cycle described as BRAC (Basic Rest-Activity Cycle) and the Ultradian Rhythm or Ultradian Shift. This latter term was popularised by Ernest Rossi in his book The 20-Minute Break.

This lesson includes a video by Dawson Church, a health writer and researcher, which explains the Ultradian Rhythm and how to understand and harness it to avoid the negative impact of stress.

In the following video, Dawson Church explains Ultradian Rhythms, which refers to the same pattern as the rest-activity cycle.
