Couples Who Go To Bed At The Same Time Report Happier Marriages

Survey Suggests Mismatched Sleep Schedules Could Be Straining Your Relationship

Most people know a good night’s sleep matters. Fewer think of it as relationship advice. A national survey of 2,000 married Americans found that couples who go to bed at the same time are more likely to describe their marriage as “very happy,” and most couples aren’t doing it nearly as often as they might expect.

On a typical week, married couples go to their shared bed together just three nights. An 80-minute gap between when one partner turns in and when the other follows plays out multiple times a week in homes across the country. Researchers call it the “bedtime gap,” and it turns up as a quiet but consistent factor in how married Americans rate their relationships.

Commissioned by mattress brand Avocado Green Mattress and conducted by survey firm Talker Research, the data draws on responses from married Americans who live with their spouses. While it doesn’t prove cause and effect, the patterns it reveals are hard to overlook.

The Bedtime Gap Hiding in Plain Sight

Talker Research surveyed respondents online between February 2 and 5, 2026, asking about their sleep habits, bedtime routines, and how happy they felt in their marriages. Respondents answered questions about how often they went to bed at the same time as their partner, whether they shared a general sleep chronotype (meaning both tended toward night owl or early bird hours), and whether coordinated bedtimes affected sleep quality or emotional closeness. Participants were required to live with their spouses and have internet access.

What emerged was a picture of widespread bedtime mismatches: couples averaging only three shared nights per week, with that 80-minute window between one partner’s bedtime and the other’s playing out on multiple nights. It’s a routine disconnect that many couples may not have stopped to name, let alone address.

Shared Bedtime and Marriage Happiness: What the Data Shows

Among couples who called themselves “very happy” in their marriages, going to bed together happened about four nights per week. Among those who described their marriages as less-than-happy, that number dropped to roughly once a week. More than half of all respondents (58%) said they felt closer to their spouse when sharing a bedtime, and a nearly identical share (59%) said going to bed at the same time mattered for physical intimacy.

Sleep quality also tracked with bedtime coordination. Four in 10 respondents (43%) said they slept better when they and their partner turned in together, compared to just 16% who said their sleep improved when they went to bed at separate times.

Laura Scott, director of brand marketing at Avocado Green Mattress, addressed what the data seemed to be pointing toward. “But these results do show the importance of connection, and how bedtime can be a meaningful time for couples — whether that’s a chance to talk and debrief about the day or have some alone time for intimacy,” Scott said. “It can be so lovely to share a bed with your spouse after a long day, and many respondents said they actually sleep better when going to sleep at the same time as their partner.”

Night Owl vs. Early Bird: When Sleep Styles Don’t Match

Matching sleep chronotypes also correlated with marriage satisfaction. Among couples where both partners were natural early risers, 78% called themselves “very happy.” Among dual night owl couples, that figure was 71%. Among couples with one early bird and one night owl, satisfaction fell to 59%, a gap of nearly 20 percentage points compared to well-matched early birds.

Scott was careful not to overread that finding. “Should night owls only marry other night owls, and should early birds only marry other early birds? No,” she said. “There are plenty of ways to make a relationship work when you have different needs and varying sleep schedules, something so many couples are familiar with.”

Why Younger Couples Feel the Shared Bedtime Effect More Strongly

Age shaped the results in notable ways. Among millennial respondents, 62% said they slept better when going to bed at the same time as their spouse. Among baby boomers, just 27% said the same. Millennials also reported feeling closer to their partners through shared bedtimes at a much higher rate, 76% compared to 41% for baby boomers, even though overall marriage satisfaction scores didn’t differ dramatically between the two groups.

Scott offered a possible explanation. “What you need to have a good night’s rest can change as you age, just as your relationship can evolve over time,” she said. “Older Americans might be more settled into their marriages, and therefore be prioritizing sleep in a different way. What’s most important is that everyone is getting the rest they need, knowing the impact sleep can have on our overall health and wellness.”

For couples already sharing a bed, the survey suggests that simply sharing a bedtime, too, may be doing quiet work for the relationship, even if nobody thinks to call it a strategy.
