A MadeForMums report reviews research and expert commentary on how sexual activity and intimacy may affect stress, mood, sleep and some cognitive measures. The evidence does not establish that sex prevents dementia or directly protects the brain, and sex is not necessary for brain health.
MadeForMums has reported on possible links between sex and brain health, including stress, mood, sleep and cognitive test performance. The article draws on expert commentary and a small study of older adults, but it does not show that sex prevents dementia or directly protects the brain.
The report says sexual activity and satisfaction have been associated with lower cortisol, a hormone involved in the body’s stress response. Neuroscientist Dr Tara Swart told MadeForMums that regular sex can improve mood, relaxation, self-esteem and sleep quality. Those are expert statements about potential benefits, not proof that sex produces the same effects for everyone.
Swart also described the release of dopamine, oxytocin, serotonin and endorphins during sexual arousal as relevant to feelings such as pleasure, trust and connection. The report presents a possible pathway: lower stress and improved wellbeing could support brain health. It also notes that research has not established a direct causal relationship between sex and long-term brain outcomes.
For cognition, the report points to a 2017 study in The Journals of Gerontology, which found that sexually active older adults scored higher on some cognitive tests, including measures related to executive function and working memory. The source describes the research as small and says the association does not prove that sexual activity caused the higher scores.
What the Brain Claims Mean
The report is relevant to readers because it connects everyday wellbeing with questions about stress and cognitive health, while distinguishing suggestive findings from established medical conclusions. Chronic stress has been linked in research to health concerns, and the Alzheimer’s Society, as quoted in the report, says stress can affect the immune system and contribute to inflammation that may harm brain cells.
But these points do not mean sex is a treatment for stress-related illness or a way to prevent dementia. The evidence cited offers possible associations and mechanisms, not proof of a protective effect. Readers should not feel pressure to have sex for health reasons: the report explicitly says sex is not essential for brain health, and wellbeing can come from other forms of connection and stress relief.

What the Cited Research Shows
The MadeForMums article frames sex as one part of broader wellbeing, alongside sleep, diet and exercise. It reports that sexual activity may shift the body away from a heightened stress response, and that pleasurable experiences can be accompanied by changes in hormones associated with mood and attachment. These biological explanations offer context, but they do not establish long-term outcomes.
The article also emphasizes that consent, comfort and relationship quality matter. Clinical sexologist Marie Morice told the publication that research is less about how often people have sex than whether experiences are willing, positive and stress-reducing. Psychotherapist Eloise Skinner similarly said benefits may be less consistent in relationships lacking emotional closeness or reciprocity. Kissing, touching and other forms of intimacy may also support wellbeing, according to the report.
“Regular sex improves mood, happiness, relaxation, sense of belonging, self-esteem, reduces stress and improves sleep quality.”

Limits of the Evidence
Cause and effect remain unclear. The report says studies linking sexual activity with brain health cannot establish whether sex itself changes cognition or whether other factors account for the association. The 2017 findings concern higher scores on some tests among sexually active older adults; they do not show that sex prevents dementia or preserves cognitive function over time.
The source does not provide enough detail to assess the study’s sample size, methods or the size of the reported differences. It also does not establish how results vary across people, relationships or types of sexual activity. Individual responses differ, and the article cautions that benefits may not be consistent in every encounter or relationship.
How to Read Future Findings
The report provides no upcoming study or policy milestone. Further research would be needed to test whether the observed links persist over time and to separate sexual activity from related factors such as health, relationship quality and general wellbeing. Until then, the findings are best understood as suggestive rather than conclusive.
For readers, the practical takeaway in the source is that sex is optional, not a brain-health requirement. Any intimacy should be willing and comfortable; other meaningful forms of connection and stress relief remain relevant when libido is low or sex is not possible or desired.
Key Questions
Does sex prevent dementia?
No evidence cited in the report establishes that. It discusses possible links between stress, sexual wellbeing and brain health, but does not show that sex prevents dementia.
What did the 2017 study find?
The report says sexually active older adults scored higher on some cognitive tests, including measures of executive function and working memory. The finding is an association and does not prove sex caused the difference.
Do people need to have sex for brain health?
No. The report says sex is not essential for brain health. It also points to other forms of intimacy, such as kissing and touching, while stressing that experiences should be willing and feel positive.
Are the reported effects the same for everyone?
No. The article notes that people may have different responses to arousal and orgasm, and that experiences can vary with wellbeing and relationship circumstances.
