Hot sex doesn’t just blow minds — it sharpens them. Getting lucky stimulates your brain and helps fight dementia, a study claims.

Older guys who engage in lovemaking regularly have better brain health and are less likely to lose memory.

Men with active sex lives between the ages of 50 and 89, scored 23 per cent higher on cognitive word tests and three per cent higher on numbers puzzles, said the researchers, who quizzed 6,800 people.

Sex hormones, like dopamine, are linked to the brain’s reward centre and help cognitive function.

For the study, participants were asked to recall 10 words five minutes after hearing them. They were also handed a number sequence, with one digit out of place, and asked to correct the pattern.

“The findings have implications that maintaining a healthy sex life in older age could be instrumental in improving cognitive function and well-being,” the study said.
