As individuals age, their bodies undergo various physiological changes that affect their ability to regulate temperature. One significant change is that circulation becomes less efficient with age. This decreased efficiency can impair the body's ability to maintain a stable internal temperature in response to external temperatures.

Older adults may have reduced blood flow, which affects heat distribution throughout the body. This can result in difficulties with both heat dissipation in hot environments and heat retention in cold environments. Additionally, factors such as reduced skin sensitivity and decreased sweat gland function further compound this issue, making older adults more vulnerable to both heat-related illnesses and hypothermia.

By understanding this aspect of age-related physiology, older adults can be better informed about the importance of monitoring their body temperature and taking appropriate precautions in extreme weather conditions.
