January has officially earned an unsexy new title. According to new research, it’s the month when couples are least likely to get intimate – and it’s not hard to see why.
A poll of 2,700 adults by IllicitEncounters.com, the UK’s leading affairs site, has revealed that sexual frequency drops sharply in January compared to December, with many couples admitting that once the fairy lights come down, so does their libido.
When asked to choose which month they tend to have the most sex, December comfortably topped the list, with 22% saying it’s their most active month. Summer also proved popular, with July (16%) and August (14%) rounding out the top three.
January, meanwhile, sat firmly at the bottom of the table, with just 2% saying it’s when they have the most sex, confirming it as the nation’s least passionate month.
While December is fuelled by indulgence, socialising and late nights, January brings the opposite: fatigue, restraint and a collective national comedown.
The biggest libido‑killer? Exhaustion. Nearly two‑thirds (64%) said the chaos of Christmas left them too drained to feel sexual in January.
Money worries also played a major role. Almost half (47%) said post‑Christmas financial stress made it difficult to relax or feel in the mood.
Meanwhile, Dry January has been dampening more than just alcohol intake. A third (33%) said going booze‑free reduced spontaneity and intimacy at home.
Even healthy habits are sabotaging sex lives. 29% said early‑morning gym sessions and new fitness routines left them “too tired” for sex at night, while 24% admitted that poor body confidence after festive overindulgence made them less likely to initiate intimacy.
The survey also revealed stark regional differences when it comes to the January bedroom slowdown. London topped the list, with 38% of respondents saying their sex life dips dramatically in January, followed by the South East (34%) and the North West (31%).
At the other end of the scale, Northern Ireland reported the smallest post-festive slowdown, with just 13% saying January has a noticeable impact on their intimacy levels – suggesting some regions are shaking off the winter lull far better than others.
Jessica Leoni, sex and relationships expert at IllicitEncounters.com, says January creates the perfect storm for intimacy to take a back seat.
“January is all about restriction – spending less, drinking less, eating less, sleeping more and waking up earlier,” she explains. “Unfortunately, sex often becomes another thing people subconsciously cut back on.”
She adds: “When stress, fatigue and self-consciousness creep in, desire is usually the first casualty. It’s why January consistently shows the biggest dip in sexual frequency, even among otherwise happy couples.”
Leoni says the key is recognising the slump rather than ignoring it. “Intimacy doesn’t have to disappear just because it’s cold, dark and payday feels miles away – but January definitely makes it harder to prioritise connection unless couples actively make the effort.”
