Frequent Sauna Use and Dementia
A recent study by the University of Eastern Finland finds that frequent sauna use may lower rates of dementia and Alzheimer’s disease.
In this article, we look at frequent sauna use and dementia rates.
In their study, they analyzed 2, 315 apparently healthy men aged 42–60 years.
They found that moderate to high frequency sauna bathing in this male population was associated with lowered risks of dementia and Alzheimer’s disease.
Dementia and Alzheimer’s Disease
The study was conducted by dividing male participants into three groups. Those who:
- Took about a 15-minute sauna 4-7 times a week
- Used a sauna 2-3 times a week
- Only used a sauna once a week.
The researchers found a legitimate response between dementia risk and the frequency of weekly sauna baths.
For those men who used a sauna more frequently than one time per week (4-7 times), their risk of dementia was lower by 66%. What’s more, their risk of Alzheimer’s disease was 65% lower than those men using a sauna only once per week.
This study was conducted over a period of 20 years, and results were adjusted for age, body mass index, systolic blood pressure, smoking status, alcohol consumption, Type 2 diabetes, previous myocardial infarction, resting heart rate, and serum low-density lipoprotein cholesterol.
Heart Disease and Stroke
These same researchers found in another study that men who used a Finnish style, 175°F dry-heat sauna for an average of 14 minutes per visit, 4-7 days of the week, had significantly lower death rates from cardiovascular disease and stroke than those who only used the sauna once a week.
It’s not surprising that saunas are good for you. It’s been known for a long time that sauna bathing has protective properties when it comes to the heart and memory. Yet, we are still learning how.
On a final note, while the study had positive results regarding the frequency of sauna bathing and its association with risk of dementia and Alzheimer’s disease, they do recommend further studies to establish the potential mechanisms linking sauna bathing and memory diseases.
