Which position requires one to lie face down, and therefore may be difficult to tolerate by older persons?

The prone position, where an individual lies face down on their stomach, can be particularly challenging for older adults for several reasons. As people age, they may experience various physical limitations, such as reduced mobility, arthritis, or discomfort in their joints. Lying face down can put additional strain on the neck and back, making it uncomfortable for those with existing health issues.

Furthermore, older adults may have difficulty breathing comfortably in this position if they have certain medical conditions, such as chronic obstructive pulmonary disease (COPD) or heart issues. The prone position also requires a degree of flexibility and balance that may not be present in some elderly individuals. Thus, the discomfort and challenges associated with maintaining this position can lead to intolerance, highlighting why it may not be suitable for many older persons.
