“…A correlation has also been suggested between feelings of fatigue and cardiac indices in healthy individuals (22). The thermal vasodilation resulting from Waon therapy reduces cardiac pre-and afterload, which has been reported to significantly improve the ejection fraction in patients with chronic heart failure (4).…”

Effects of Waon Therapy on Chronic Fatigue Syndrome: A Pilot Study

et al. 2015

Objective Chronic fatigue syndrome (CFS) is a disabling condition of unknown etiology, and no definitive therapy has been identified to date. We developed Waon therapy, a form of thermal therapy using a farinfrared dry sauna, and in this study herein examined its feasibility and safety in patients with CFS. Methods Ten consecutive inpatients with CFS stayed in a 60°C sauna for 15 minutes and then rested on a bed under a blanket for an additional 30 minutes outside the sauna room. The treatments were performed once a day, five days a week for four weeks. Perceived fatigue, the primary outcome measure, was evaluated using a numerical rating scale before, during (two weeks after the commencement of therapy) and after therapy. The pain level, evaluated using a numerical rating scale, mood, assessed using the Profile of Mood States questionnaire, and performance status, assessed using a scale developed for CFS patients were also examined before and after therapy. Results Perceived fatigue significantly decreased after therapy, although no significant reductions were observed during therapy. In addition, a negative mood, including anxiety, depression and fatigue, and the performance status significantly improved after therapy. However, the levels of pain and vigor did not change significantly. No patients reported any adverse effects during the therapy. Conclusion These findings suggest that Waon therapy may be a useful and safe treatment for CFS.

“…Modifications of cardiac function, chronic inflammatory status, skeletal muscle modifications, nutritional deficiencies and sleep disorders may influence fatigue [4,5]. General cardiac functioning [18] and reduced aerobic capacity [9,19,20] are related to fatigue. Pain may contribute to fatigue by increasing heart rate, blood pressure, respiratory rate, muscle tone, and oxygen consumption [21].…”

Nutritional Status as a Mediator of Fatigue and Its Underlying Mechanisms in Older People

et al. 2020

Fatigue is an often-neglected symptom but frequently complained of by older people, leading to the inability to continue functioning at a normal level of activity. Fatigue is frequently associated with disease conditions and impacts health status and quality of life. Yet, fatigue cannot generally be completely explained as a consequence of a single disease or pathogenetic mechanism. Indeed, fatigue mirrors the exhaustion of the physiological reserves of an older individual. Despite its clinical relevance, fatigue is typically underestimated by healthcare professionals, mainly because reduced stamina is considered to be an unavoidable corollary of aging. The incomplete knowledge of pathophysiological mechanisms of fatigue and the lack of a gold standard tool for its assessment contribute to the poor appreciation of fatigue in clinical practice. Inadequate nutrition is invoked as one of the mechanisms underlying fatigue. Modifications in food intake and body composition changes seem to influence the perception of fatigue, probably through the mechanisms of inflammation and/or mitochondrial dysfunction. Here, we present an overview on the mechanisms that may mediate fatigue levels in old age, with a special focus on nutrition.

“…Several studies have shown that general cardiac functioning [80] and reduced aerobic work capacity [36,81] are related to fatigue. It has been shown that older adults are not able to perform daily activities when they fall below certain threshold levels of aerobic capacity.…”

The aim of this paper is to give an overview of research on general fatigue, mobility-related fatigue, and fatigability in older adults, with a focus on fatigue as an early indicator of the aging process. Fatigue is a strong predictor of functional limitations, disability, mortality, and other adverse outcomes in young-old and old-old populations, in men and women, and in different geographic localities. Several biological, physiological, and social explanations are proposed: fatigue may be seen not only as a self-reported indicator of frailty, defined as a physiologic state of increased vulnerability to stressors which results from decreased physiologic reserves and even dysregulation of multiple physiologic systems, but this state may be accelerated by the cumulative impact of social, mental, and biological factors throughout life. Fatigue in older adults is the result of multiple potentially modifiable factors, of which some may be fully treated or at least alleviated, thus slowing down the speed of the aging process.
