ABSTRACT=IntroductionHeat therapy (HT), particularly in the form of whole-body sauna bathing, has emerged as a promising intervention for the management of cardiovascular disease (CVD). Passive HT can induce both local and systemic physiological responses, primarily through repeated thermal stress consisting of short-term passive exposure to high temperatures. Such responses closely parallel the physiological adaptations observed during aerobic exercise. Peripheral arterial disease (PAD) poses significant health challenges, impacting millions of individuals worldwide. Supervised exercise is considered a cornerstone therapy for PAD, yet many patients face significant health-related barriers that complicate its broad implementation.MethodsWe conducted a comprehensive review of the literature to explore the therapeutic implications of various HT practices beyond sauna. The review aimed to evaluate the potential use of these practices as adjunctive management strategies for cardiovascular diseases, particularly in patients with PAD.ResultsRecent studies have demonstrated the potential role of HT in alleviating PAD symptoms, improving functional capacity, and reducing cardiovascular and limb events. HT practices might be beneficial as adjunctive management strategies, in addition to or as alternatives to exercise, for management of cardiovascular diseases.DiscussionThis review highlights the potential benefits, underlying mechanisms of action, challenges, and safety considerations associated with HT. We emphasize the importance of exploring HT as a viable option for patients with cardiovascular conditions, particularly those with PAD, who face barriers to traditional exercise regimens.
