It’s a signal to white blood cells and the body’s antiviral army of lymphocytes, neutrophils and interferons to come to the rescue.1,2,3 Increased body temp may also help fight infections as it stimulates heat shock proteins that deter viruses from reproducing and reduces inflammatory cytokine proteins.4 Raising body temp above normal for therapeutic treatment is called hyperthermia.

Sauna is the most effective way to induce hormesis.

Nature uses a process called hormesis to make us stronger. It’s a 2-phase response our bodies have to certain stressors, like exercise or fasting, heat or cold, where a little bit of strain creates strength or resilience. When our ancestors were less insulated from the environment, their bodies naturally responded to the challenges. Modern life requires us to recreate opportunities to challenge our immune system and sauna use is the most efficient and effective way to do that. The benefits of hormesis affect overall wellness, heart health, and immune system boost.

Do everything you can to stay well.

Using a sauna regularly helps your body stay well. An Austrian study5 of 25 healthy subjects who regularly used saunas found they had significantly fewer episodes of common colds than those who did not. This benefit becomes more significant, especially after 14 weeks of consecutive sauna use. To maximize these benefits, it’s recommended to use it at least twice a week throughout the year.
