Imagine if you could sharpen your memory and revitalize your brain just by sitting still.

Simply relax, take a nap, listen to music, meditate, or watch a DVD. While you take it easy your brain and memory are automatically revitalized.

Is this some futuristic medical device? In some ways, yes, but it’s based on techniques used for thousands of years.

It’s the amazing health and memory benefits of the infrared sauna.

Now clinical research shows that saunas have remarkable benefits to help you keep a sharp memory and a healthy brain for life.

Clinical research shows that people who used a sauna from four to seven times a week slashed their risk of Alzheimer’s disease by 65% compared to those who took one sauna per week.1 Even just one sauna a week cut Alzheimer’s risk by 20% compared to those who didn’t use saunas at all.”2

If there were a drug that reduced Alzheimer’s by this much it would be front page news. Psychology Today magazine raved, “From a public health perspective, the latest Finnish report on the neuroprotective benefits of sauna use is a potential game changer.”3

Sharpen Your Brain with More Blood Flow

Saunas help open blood vessels. This allows more blood to nourish and detoxify brain cells.4 Saunas are even shown to reverse the cardiovascular disease that leads to strokes and heart attacks.

A study published in the Journal of the American College of Cardiology showed that infrared saunas help open arteries and improve blood flow. 15 minutes in an infrared sauna each day for 14 days was shown to boost artery function by 40%.5 These benefits can help you significantly reduce the risk of dementia caused by strokes.

Grow New Brain Cells

Research also shows that saunas may help revitalize aging neurons and even grow new brain cells.  Heat from saunas is shown to stimulate the production of BDNF (brain-derived neurotrophic factor).6,7 BDNF is a powerful growth hormone that researchers call “Miracle-GRO® for brain cells.”

Other than eating right and getting enough exercise, it’s hard to think of any other thing that gives you so many health and longevity benefits as a sauna.  Unlike diet and exercise, you don’t need boring workouts or self-denial.

While you’re revitalizing your brain, your entire body gets many other benefits.

Lose Your Belly, Keep Your Brain

People who are overweight have a 3.5 times greater risk of dementia, according to a 30-year study published in Neurology.8,9 In other words, lose weight and you’ll significantly boost your odds of keeping your memory sharp your whole life.

But dieting and exercise are hard.  What if there were an easier way to burn fat and calories?

Infrared saunas have been clinically shown to dramatically aid in weight loss. A 2009 study showed that infrared saunas provide significant results in lowering weight and waist circumference after just three months of use.

And for those who are sedentary due to medical conditions such as osteoarthritis, cardiovascular or respiratory problems, results were even more profound.10

Burn up to 600 Calories While Sitting Still!

According to information published in the Journal of the American Medical Association, infrared sauna sessions were shown to burn upwards of 600 calories. During a sauna weight loss session, your core temperature increases and your body works hard to cool itself. While using an infrared sauna, there is a substantial increase in blood flow, heart rate, cardiac output, and metabolic rate, causing the body to burn more calories.11

Part Two of this article next month will show you how saunas can help protect you from memory-robbing toxins, relieve pain, prevent heart attacks, and other important health benefits.

You can try an infrared sauna at a local health club, spa, or massage therapist. A typical fee is $30-$45 per 30-minute session. I also recommend purchasing one yourself.  (It’s always important to talk to your physician before beginning sauna therapy.)

I have an infrared sauna in my home, and it’s one of the best purchases I ever made. It’s especially nice during the winter months if you live in a cold climate.

An excellent, cutting-edge manufacturer is Sunlighten, offering clinically backed 3-in-1 infrared and full-spectrum saunas with a simple plug-and-heat design for easy home installation. Visit their website or call 1-888-413-0166. Another reputable (albeit more expensive) brand is TheraSauna. Infrared saunas, with their myriad health benefits, are definitely an at-home therapy option worth checking out.
