Sauna use lowers Alzheimer’s risk by 65%

According to the Alzheimer’s Association, in the United States …

  Every 67 seconds, someone develops Alzheimer’s.

  Alzheimer’s disease is the sixth-leading cause of death.

  Approximately 500,000 people die each year because of this disease.

  In 2013, 15.5 million caregivers provided an estimated 17.7 billion hours of unpaid care valued at more than $220 billion.

Even with the remarkable progress in Alzheimer’s treatments over the past decade, there is still no cure for this horrible neurodegenerative disease.

The best we can do right now is take as many preventive measures as possible.

Which is why today’s news marks one of the biggest breakthroughs in Alzheimer’s research to date.

In a landmark study done by Oxford University, researchers have found that using a sauna four to seven times per week can reduce Alzheimer’s risk by 65%, after adjusting for diet/lifestyle.

Now, the research team can’t explain yet exactly WHY or HOW this is happening …

But it adds to the mounting evidence that saunas have incredibly powerful health benefits.

Last year, I wrote about how a half-hour of sauna time offers similar benefits to exercise for the body.

Researchers in Finland studied the effect of saunas on more than 2,300 men over a 20-year period. They found that men who used saunas four to seven times per week lived longer than men who only used saunas once a week.

The findings, published in the Journal of the American Medical Association, also found that frequent sauna users had:

  A 63% lower risk of sudden cardiac death

  A 50% lower risk of cardiovascular disease

  A 40% overall lower death rate

You see, performing aerobic exercise raises your body’s core temperature. This induces strain on the body, decreases endurance and accelerates exhaustion.

By itself, you don’t want your body’s temperature to be higher than normal for an extended period of time like when you have a fever.

But during exercise, when your body’s core temperature is raised, the body goes through a natural process called hyperthermic conditioning, or heat adaptation.

Basically, the body is in an abnormal state and will make any changes necessary to survive at this new temperature.

This process optimizes your body for the next time you exercise (and raise your body temperature). So, the body is put through less metabolic stress.

Generally, the more exercise you perform means the better heat-adapted you are.

As the body adapts to functioning at a higher temperature, it makes several changes that can have many lasting benefits — even when the body returns to normal temperature …

Research now shows that sauna use causes the body to go through this same heat adaptation.

It causes the body to go through these same physiological adaptions that benefit the body longer term.

Essentially, 30 minutes of relaxing sauna time may have the same cardiovascular and metabolic effects of intense aerobic exercise.

Which can begin to explain this new finding on the relationship between sauna use and Alzheimer’s risk.

That’s because exercise increases the number of small blood vessels that supply blood to the brain. It also boosts the number of connections between nerve cells.

Exercise has been shown to raise the level of a nerve growth factor (a protein that’s key to brain health) in an area of the brain that is important to memory and learning.

New studies have illustrated how exercise can stimulate the human brain’s ability to maintain old network connections and make new ones that are vital to healthy cognition.

In a year-long study, 65 older people exercised daily — doing either an aerobic exercise program of walking for 40 minutes, or a nonaerobic program of stretching and toning exercises.

By the end of the study, the walking group showed improved connectivity in the part of the brain engaged in daydreaming, envisioning the future, and recalling the past.

The walking group also improved on executive function. That is, the ability to plan and organize tasks such as cooking a meal.

Again, these new findings only add to the mounting evidence of the powerful health benefits of sauna use. And I believe it’s going to be one of the most important fields of study in the coming decade.

Your thoughts on “Sauna use lowers Alzheimer’s risk by 65%”

  1. There are several types of saunas available. Please be specific on what type of sauna the research used.

  2. Would a therapeutic spa deliver the same benefits? What temperatures are saunas normalky set at?

  3. Very interesting article. It would be interesting to see a study on workers in the southern areas of the United States who work daily in a hot humid condition i.e. Air condition technician or other Manuel trades to see if the is a difference in there cognitive decline or even Alzheimer’s.

  4. We’ve benefitted from taking saunas for 20 years. Previously had a fare-infrared and after a bit of research went with a near-infrared. All indications are that it is a better choice. We are both approaching 70, drug free, active and healthy. The sauna is one of several of our cell survival technology tools. The sauna is a must —

  5. I must thank u for publicising the benefits in use of sauna when the medical fraternity and the pharma cos. are distorting info. and spreading false stories about the ill effects of sauna. I am a regular user of sauna and believe me I am off medicines that I used to take earlier for various ailments.

  6. For decades, otologists have recommended using a daily niacin dose to cause a flush. This was to increase blood flow in the ears, where the blood vessels are small. This is supposed to reduce or stabilize degradation of hearing due to “nerve loss”. Several hearing aid sellers have also told me they have seen the difference in people who use niacin vs. those who don’t, benefiting the former.
    The flush occurs over the whole body, of course, very noticeable in one’s head. Have you read of any correlative effects such as the sauna? Since both increase head, and probably brain, circulation, there could be added benefits to use both, or if a sauna is not available, perhaps the niacin could be some help. Do your sources have any info on this?

  7. I am 72 year old. I am in my outdoor sauna mornings for 10 minutes and evenings 15 minutes. When I step out from the sauna I do 35 half-squatts while raising my arms in sink above my head and to the side. Summer and winter. Brings me alive and revives me.

    I do intensive deep breathing while outside of the sauna. Inside the sauna I breathe in the hot air as intensively as possible to clear my sinuses. I fear the use of histamines because of potential neuron damage.

    I am the Caplan whose successful human clinical trials in treating Sickle Cell anemia crisis in Havana, Cuba, demonstrate the safe role of raising oxygen partial pressure by the use of medical grade ozone/oxygen. Google: CAPLAN, SICKLE CELL ANEMIA for various articles.

  8. My first experience benefiting from a traditional sauna was when I spent a year studying in Sweden my JR year of college. Enjoyed a wonderful sense of well being after sauna. I enjoyed the benefit of a traditional sauna in my home years ago. After moving, I longed for the therapeutic good feeling known after sauna. Bought a small Finnish Helo far-infrared sauna for my current home. Gives me a peaceful sense of well-being as it relaxes sore muscles, yet leaves me feeling invigorated. Known to detoxify impurities from one’s body, it appears to keep me healthy, as I catch no flues or winter colds. The study is believable to me, as sauna creates an active healthy circulation, which might oxygenate the brain a bit. Showering after a pleasant, rejuvenating sauna, I feel cleansed internally to externally from my toes to my brain. Sauna is enjoyably part of my Swedish heritage. 🙂

  9. I hit the sauna every day at the gym I go to. My body has a tendency to retain water and this is the best way to loose 4 or 5 pounds of water weight! Lowers my blood pressure and makes me feel great.

  10. Brad,
    I’ve been using a sauna extensively for 16 years. I’ve read it reduces cancer risk as well. I had a toxic injury 17 years ago which damaged my body’s detoxification abilities. So I regularly use the sauna, I’d say about 5 hours a week, to detox. So glad to see all of the health articles that you post. You are doing a great public service. Keep up the good work!

  11. I purchased a sauna a few months ago and have it set up in my basement. So far I have only used it about three times. After reading your story about the health benefits, I am looking forward to using my sauna on a regular basis going forward.

  12. We bought an infared sauna last year and use it every other day in the winter. In the summer it would be to unbearable. After reading your story maybe we will start using every day. We love it! Dropping 10+ pounds in short order and I’m not over weight. Thanks!
