A Finnish study shows that staying in a sauna for 30 minutes increases immune cells #130

Research results showing that white blood cells increase with a 30-minute sauna.

A research team including the University of Turku conducted a study on 51 adults with an average age of 50, revealing that a 30-minute sauna bath increases all types of white blood cells circulating in the blood. It is quite interesting that the movements of neutrophils and lymphocytes were closely observed in an experiment that included taking a cold water shower in the middle.

The mechanism where a phenomenon similar to exercising occurs.

Since neutrophils and others return to normal values within about 30 minutes after the sauna ends, this is explained as a phenomenon where cells stored in tissues are temporarily mobilized into the blood. It was mentioned that a similar release occurs during exercise, which is beneficial because it patrols the body and makes it easier to respond to pathogens.

It is a temporary change and future verification is awaited.

Since this measurement looks at the immediate effect of a single session, the paper published in the academic journal "Temperature" warns that it cannot be determined how repeated bathing affects long-term health.
