Much of the world has fallen into a sedentary lifestyle. An overall decrease in activity and the rise of office jobs has led not only to decreased physical activity but also to numerous health conditions, such as high blood pressure and spinal issues from poor posture. For some people, however, sitting or reclining is the treatment, rather than the cause, of a health condition. Standing up triggers orthostatic intolerance, which often occurs alongside other illnesses.


1. What Is Orthostatic Intolerance?

Orthostatic intolerance (OI) involves a series of physical symptoms that are triggered by standing up and relieved by reclining once again. Multiple disorders are associated with orthostatic intolerance, including dysautonomia, an autonomic nervous system disorder. Some causes are less serious, however, and do not generally require medical attention or intervention.
