NEW YORK – The moment arrives in most modern relationships, eventually. The bedroom light dims. One or both people reach for their phones instead of each other. Fifteen minutes later, half an hour, the screen still glows. The impulse that might have been there at the start of the evening has quietly retreated.
A study published in June in BMC Psychology now offers a formal explanation for what many couples have been sensing without the vocabulary to name it. Social media addiction, researchers found, is meaningfully associated with lower sexual desire. The more addicted to social platforms a person scores, the less they report wanting sex.
The research, led by Andrea Varaona-Santos and colleagues in Spain, used an online cross-sectional survey to examine how social media use, addiction scores, depressive symptoms, and relationship status interacted with self-reported sexual desire. The findings arrived at a moment when the average adult spends two to three hours a day on social platforms and when clinicians are increasingly being asked to address what some are calling a quiet erosion of sexual interest in otherwise healthy adults.
The study’s most counterintuitive finding may be what it reveals about cohabitation. Conventional thinking suggests that couples sharing a home have more opportunity for sex, and therefore more desire. The data pointed the other direction. Participants who lived with a partner reported sexual desire scores approximately 1.6 points lower than those who did not cohabit. That gap was statistically significant. Whatever closeness produces, the study suggests, it does not reliably produce more wanting.
What might explain that? The researchers did not offer a definitive mechanism, but the variables are familiar enough. Couples who live together become enmeshed in the logistics of a shared life: bills, domestic tasks, morning schedules, conversational routines that replace novelty with efficiency. When the phone offers stimulation at a moment’s reach, it may simply out-compete what the domestic environment can offer. The effect of social media on desire, in this reading, would not be the only pressure on cohabiting couples. It would be one pressure among several.
For those curious about how often couples in love actually have sex, earlier research has found the number is lower than many people assume and appears to decline further when one or both partners are consumed by their screens.

Age added a further dimension to the findings. Older adults who scored similarly to younger participants on social media addiction and depressive symptoms showed significantly lower sexual desire, suggesting the suppressive effect of compulsive scrolling is not distributed evenly across the lifespan. Among the variables studied, age emerged as the strongest single predictor. For those in older age brackets who also carry high social media use, the combination appears to compound.
Depression contributed meaningfully to the association as well. This complicates any tidy causal account. Does social media addiction reduce desire by feeding depressive states? Or does depression increase social media use, which then amplifies the effect on libido? The study’s cross-sectional design cannot resolve that question. Neither can it establish whether the relationship runs from addiction to low desire, or the other direction entirely: that people already experiencing low desire turn to their phones for stimulation. What the study documents is a correlation, and a consistent one.
The team drew participants through an online survey using validated instruments for measuring social media addiction, sexual desire, and depressive symptoms. The researchers acknowledged the limitations of a one-time, self-reported study conducted among Spanish-speaking participants. Larger, longitudinal research across different populations would be needed to confirm the pattern and trace the direction of causation.
The complaint that phones are displacing desire has been showing up in therapy rooms for years; what has been missing is a measurement to put behind it. For those already working on reigniting low libido, reducing social media consumption may now be worth adding to the conversation, not as a guaranteed cure, but as a variable the research suggests is genuinely involved.
The study does not tell you to delete your apps. That would be a cleaner conclusion than the evidence actually supports. What it does is give measurable shape to something many people have been describing in vague terms: the sense that something has receded from their evenings, and that the thing glowing in their hands may be part of the explanation. For couples wondering why the spark feels harder to locate, the research offers neither a diagnosis nor a simple remedy. It offers, at least, a number and a question worth asking.
