A MadeForMums report examines research and expert views on how sexual activity and intimacy may relate to stress, mood, sleep and some cognitive measures. The evidence described is limited and does not establish that sex directly protects the brain or prevents dementia.
MadeForMums has published a report examining whether sex and other forms of intimacy may support aspects of brain health, including stress regulation, mood and cognition. The report cites expert commentary and a small study of older adults, while stressing that the evidence does not show that sex directly protects the brain or prevents dementia.
The report says sexual activity and satisfaction have been associated with lower cortisol, a hormone involved in the body’s stress response. It presents that relationship as a possible route to relaxation, not proof that sex prevents long-term brain damage. The Alzheimer’s Society, quoted in the report, says chronic stress can affect the immune system and contribute to inflammation, which may damage brain cells and affect how they communicate.
MadeForMums also describes the release of dopamine, oxytocin, serotonin and endorphins during sexual arousal and activity. Neuroscientist Dr Tara Swart says these chemicals are associated with feelings such as trust, excitement, joy and love. The report links such experiences to mood and wellbeing, but does not establish that these hormone changes produce lasting improvements in brain health.
On cognition, the report points to a 2017 study in The Journals of Gerontology involving older adults. It says sexually active participants scored higher on some cognitive tests, including measures related to executive function and working memory. That finding is an association; it does not demonstrate that sexual activity caused the scores or that it prevents cognitive decline.
Intimacy and Stress Regulation
The report addresses a familiar question for readers balancing work, caregiving and exhaustion: whether intimacy has effects beyond a relationship. Its account suggests that pleasurable, consensual experiences may help some people feel less stressed, and that stress, mood and sleep are relevant to general wellbeing. These possible links are not a medical reason to have sex, and the report explicitly says sex is not essential for brain health.
That distinction matters because the evidence described is not strong enough to support claims that sex prevents dementia or reliably improves memory. Readers can take the report as a discussion of possible associations and expert interpretations, rather than as a clinical recommendation. The article also notes that kissing and touching may be forms of intimacy, and that people can experience sexual pleasure without a partner.

What the Evidence Measures
The report places its discussion within broader concerns about chronic stress and later-life cognitive health. It quotes the Alzheimer’s Society on possible links between stress, immune responses and inflammation in the brain. This context describes why stress regulation may be relevant; it does not mean that sex has been shown to reduce dementia risk.
The cognitive finding cited is from a 2017 study of older adults, as described by MadeForMums. The report does not provide the study’s sample size, effect estimates or enough methodological detail to assess how large the differences were. It also notes that researchers face difficulty proving a causal relationship between sexual activity and brain health. A higher score among sexually active participants could reflect other differences between participants.
“Regular sex improves mood, happiness, relaxation, sense of belonging, self-esteem, reduces stress and improves sleep quality.”
— Dr Tara Swart, neuroscientist, as quoted by MadeForMums
Limits of the Brain Research
Direct cause and effect remains unproven. The report says research cannot establish that sex itself protects the brain, and the 2017 cognitive finding is an association. The supplied source material does not give the study’s sample size, detailed methods or effect sizes, so the strength and reach of that result cannot be assessed here.
People also differ in their bodies, relationships and responses to sexual activity. The report says benefits may be less consistent when a relationship lacks emotional trust or when sex is experienced as purely physical. It does not quantify how often the described effects occur, how long they last, or whether they apply across different ages and health conditions.
More Evidence Is Needed
The report describes an existing body of research and expert interpretation; it does not announce a new study or a future research milestone. Clearer answers would require studies that report their methods and measure sexual wellbeing, stress and cognitive outcomes over time, while accounting for other factors that may affect those outcomes.
For now, the report’s practical message is limited: people may value consensual intimacy for connection or relaxation, but there is no established frequency or brain-health prescription. Its account does not support treating sex as a way to prevent dementia.
Key Questions
Does sex prevent dementia?
No such effect is established by the evidence described in the report. It discusses possible links between stress and brain health, but says research does not prove that sex directly protects the brain or prevents dementia.
What did the 2017 study find?
As summarized by MadeForMums, older adults who were sexually active scored higher on some cognitive tests, including measures related to executive function and working memory. The finding shows an association, not that sex caused the difference.
Do the reported benefits require a partner?
No. The report says people do not need a partner to experience sexual pleasure. It also discusses kissing and touching as other forms of intimacy.
Is there a recommended frequency for sex to support brain health?
The report gives no recommended frequency. Morice says the focus should be on positive, willing experiences that feel good and reduce stress, rather than how often people have sex.
