Want to cut your risk of developing age-related dementia?
Hang out in a sauna at least 4 times a week! Finnish researchers analyzed 20 years’ worth of data from the Heart Disease Risk Factor Study. And they found people who spent 20-minutes in a sauna on most days were 66% less likely to be diagnosed with any form of dementia, including Alzheimer’s. The researchers aren’t sure WHY sweating in a 170-degree sauna lowers dementia risk… but they believe it’s partly because heat increases the resting heart rate, which sends more oxygen-rich blood to the brain.
