Immunity & General Wellness

You want to strengthen your system.

We understand you want to do everything you can to stay healthy and well. You already manage your diet, your fitness and activity levels, your water intake, your mental health. Adding in infrared sauna use to your wellness routine can help even more, especially now. Its natural preventative properties help support all your goals with benefits for circulation, weight loss, sleep, immunity, stress relief and temporary pain relief.


Increase core body temp, activate your immune system.

Your body naturally defends itself. During a fever, body temperature rises and strengthens the immune system. 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. Sunlighten’s infrared heating technology gives you the highest quality and quantity of infrared clinically proven to raise core body temperature by three degrees.


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 study(5) 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.
