Summary

Aging is associated with a decline in cardiovascular health, cognitive function and losses in muscle strength, with half or more of those over age 65 suffering from two or more comorbidities (e.g., heart disease, type 2 diabetes). The worldwide population of older adults is growing rapidly, with one in six people expected to be over age 65 by 2050. This will place further financial burden from chronic diseases on already stressed healthcare systems. While studies show that frequent exercise is an effective way for older adults to maintain or improve cardiovascular and metabolic health, older individuals are less physically active and do not adhere well to exercise programs, often due to physical or medical limitations. Therefore, alternative methods for older adults to get the same health benefits as exercise require further exploration. Recent work has shown that passive heat therapy may be one such alternative solution.
