Numerous studies have noticed that loneliness and social isolation are associated with cognitive decline in later life; however, these analyses do not often consider one of the most intimate types of social activity: sex.
What’s more, some experts think that a lack of social activity is a repercussion of cognitive decline and not a cause of it.
Nevertheless, the models that Shena and Liub ran in their study suggest that the link between sex and cognitive health does not go both ways.
In other words, they found better cognition was not predictive of sexual activity five years on.
Shena and Liub have put forward several explanations for their results.
First, sex often involves physical exercise, which means improved cognitive performance may be due to improved cardiovascular health, which, in turn, can increase blood flow to the brain and reduce inflammation.
Sex is also known to reduce stress, and stress is thought to prevent the neuronal growth in some parts of the brain associated with memory.
Lastly, sex may improve cognitive function through the release of dopamine, which is a neurotransmitter linked to improved memory.
There have been lots of studies showing correlation between sexual activity and various aspects of better health. This is the first one I have seen that supports sexual activity being a causation of better cognitive health.
This post was motivated by Archer who suggests Dr. Joe’s Cure For Everything could fix the entire country. The country could sure use some improved cognitive function.
Do your patriotic duty.
