Night owls face higher anxiety risk, new research suggests it’s not the late bedtime itself causing trouble, but what happens during those quiet hours alone
Anyone who has lain awake at 1 a.m. replaying an awkward conversation or worrying over an unanswered email knows that problems can feel bigger in the dark. Now, new research suggests there may be a real psychological reason behind that experience, and it has less to do with the clock and more to do with company.
A study presented at the SLEEP 2026 conference found that people who naturally stay up late tend to report higher rates of anxiety and poorer overall mental health than those who go to bed early. But according to the researchers, the timing of sleep wasn’t the main driver. Instead, the bigger factor appeared to be loneliness experienced specifically at night.
What the study examined
The research involved 442 adults who completed a series of questionnaires. These assessments measured four things: chronotype (a person’s natural tendency toward being a morning or evening type), general loneliness, nighttime loneliness specifically, and symptoms of anxiety.
Researchers wanted to understand why so-called evening chronotypes, people who naturally feel more alert later in the day and prefer to go to bed later, consistently report worse mental health outcomes than early risers.
The role of nighttime loneliness
The results showed a clear pattern. People with an evening chronotype reported more anxiety, more loneliness overall and, notably, more loneliness during nighttime hours specifically.
When researchers factored in that nocturnal loneliness, something interesting happened. The direct statistical link between being a night owl and experiencing anxiety largely disappeared.
In other words, staying up late on its own didn’t appear to be the problem. What seemed to matter more was the isolation that can come with being awake while everyone else is asleep.
Why this connection makes sense
Sleep researchers have long noted that sleep isn’t purely a biological function. It also shapes a person’s social life. The hours someone is awake determine how often they can interact with friends, family or roommates, and how connected they feel to the people around them.
For a night owl, the late hours after most people have gone to bed can become a stretch of time with limited opportunities for connection. That gap, researchers suggest, may be where anxious feelings take root.
Loneliness and long-term health
This finding adds to a growing body of evidence on loneliness and its effects on the body and mind. Over the past decade, studies have repeatedly linked chronic loneliness and social isolation to higher risks of depression, heart disease, cognitive decline and even earlier death.
That broader research is part of why scientists are increasingly interested in how sleep timing, social connection and overall health intersect.
What night owls can do
The study’s authors aren’t suggesting night owls need to become early risers. Instead, they point to a few practical strategies that may help.
Getting outside earlier in the day and exposing yourself to natural morning light can help regulate the body’s internal clock. Keeping a consistent sleep schedule, even on weekends, may also support better rest.
Beyond sleep habits, the research points to the value of building connection into late hours. That might mean calling a friend earlier in the evening before they go to bed, planning social activities that fit an evening schedule, or cutting back on solo scrolling through phones, which can amplify feelings of isolation rather than ease them.
The bottom line
The study reinforces a broader idea that’s gained traction among health researchers: Wellbeing isn’t shaped only by diet, exercise or sleep duration. Relationships and a sense of connection matter just as much.
For night owls, the late hours themselves may not be the issue. What happens, or doesn’t happen, during those hours in terms of human connection could make all the difference.
