Final answer:
Older adults are more susceptible to overheating due to a decrease in homeostatic efficiency with age. This makes them particularly vulnerable to heat stroke in warm weather, and measures should be taken to ensure their safety during physical activities.
Step-by-step explanation:
In warm weather, organizations must ensure that older adults participating in physical activity are protected against the potential challenge of overheating. During the normal aging process, there is a reduction in the efficiency of the body's homeostatic mechanisms, which includes the ability to regulate body temperature. This places elderly individuals at a higher risk for heat stroke and other health issues related to their bodies overheating. Additionally, older people may experience a decline in insulin sensitivity and an increased risk of developing diseases such as type 2 diabetes. To protect the health of older adults, it is crucial to monitor their temperature and provide adequate hydration and rest during physical activities in warm climates.
