Regular sauna bathing elicits significant physiological responses that contribute to enhanced cardiovascular and metabolic health. The heat exposure induces vasodilation, leading to improved blood circulation and reduced arterial stiffness, which collectively lower resting heart rate and blood pressure. This thermal stress also stimulates the production of heat shock proteins and anti-inflammatory cytokines, thereby decreasing systemic inflammation. Neuroprotective effects are also observed, as sauna-induced increases in brain-derived neurotrophic factor (BDNF) support cognitive function and may reduce the risk of neurodegenerative diseases such as dementia and Alzheimer’s disease. @drericberg
