Cornell-trained physician shares health benefits of regular sauna use

Study Findings

Dr Vassily Eliopoulos, a board-certified emergency medicine physician trained at Cornell, states that regular sauna use serves as a powerful passive longevity tool. In an Instagram video shared on August 1, Dr Vassily cited a Finnish cohort study following over 2,000 men for 20 years. The study found that men using a sauna four to seven times per week experienced a 40 percent lower risk of all-cause mortality compared to those using it once a week. Cardiovascular deaths dropped by 40 percent, sudden cardiac deaths dropped by 63 percent, and fatal coronary disease dropped by 48 percent.

Body Response

A sauna raises core body temperature by 1 to 2 degrees and increases the heart rate to 100 to 150 beats per minute, matching the effects of moderate aerobic exercise. This triggers blood vessel dilation, increases cardiac output, and improves thial function. Over time, regular sessions lower blood pressure, reduce arterial stiffness, and improve heart rate variability while lowering high-sensitivity CRP inflammation markers. New research also suggests heat shock protein formation aids cognitive protection by helping clear misfolded proteins tied to Alzheimer's.

Context

Traditional dry saunas match the research data most closely because infrared saunas operate at lower temperatures with less robust data. Medical professionals often study heat therapy as a way to mimic certain physical benefits of cardiovascular workouts for individuals unable to perform high-impact exercises.
