Frequent sauna use may reduce dementia risk in men


Researchers in Finland have identified a link between regular sauna use and reduced risk of Alzheimer’s disease and other dementias in men.

The authors of the study which you can read in full here concluded:

“In this male population, moderate to high frequency of sauna bathing was associated with lowered risks of dementia and Alzheimer’s disease. Further studies are warranted to establish the potential mechanisms linking sauna bathing and memory diseases”

The researchers speculate that sauna use increases heart rate in a way that is comparable to exercise, which benefits heart health. This same mechanism could also be beneficial for memory, the team suggest.

Compared with men who used a sauna once a week, men who used a sauna four to seven times weekly were found to be at 66 percent lower risk of any dementia and had a 65 percent lower risk of developing Alzheimer’s disease.

Dementia game ‘shows lifelong navigational decline’

The world’s largest dementia research experiment, which takes the form of a video game, has indicated the ability to navigate declines throughout life.

Getting lost is one of the first symptoms of Alzheimer’s disease and the researchers at University College London believe the results presented at the 2016 Neuroscience Conference could help makea test for dementia.

Sea Hero Quest is a nautical adventure to save an old sailor’s lost memories.


The game anonymously records the player’s sense of direction and navigational ability through each level. Players have to weave through waterways and fire a flare back home as well as memorising a sequence of buoys.

Data harnessed from the flare levels suggests that sense of direction declines consistently after the teenage years. Players aged 19 were 74% accurate at firing the flare back home, but accuracy fell year by year until it reached 46% at age 75.

The point of the research is to develop a way of diagnosing dementia in its earliest stages – something not yet possible.
