A recent study has found a link between a person’s natural sleep timing and their emotional well-being. The research, which involved more than 500 university students, suggests that people who stay up late, known as evening types, may be more likely to report symptoms of depression.
The study indicates that the connection is not just about the hours of sleep a person gets. Instead, it points to lifestyle habits and mental patterns that often accompany a late-night schedule. Researchers found that evening types tended to have lower sleep quality, including inconsistent bedtimes and social jet lag. They also reported higher alcohol intake, especially on late nights out, and engaged in more rumination, which is repetitive, negative thinking.
A key factor identified in the study was mindfulness, specifically a skill called “acting with awareness.” This is the ability to stay present without judgment. The study found that evening types scored lower in this area. Morning types, on the other hand, scored higher, possibly because better sleep supports clearer focus and emotional regulation. The researchers concluded that these factors together help explain why night owls experienced more depressive symptoms than their early-rising peers.
The study’s authors suggest that mindfulness can be trained. Practices such as meditation, journaling, and setting aside intentional screen-free time before bed may help strengthen awareness and quiet the mind. For those who are naturally inclined to stay up late, the recommendation is not to completely change their chronotype. Instead, small shifts may help support mood.
These shifts include aiming for a consistent bedtime and wake time within an hour each day. Reducing alcohol intake, especially close to bedtime, is also advised. The study also recommends practicing mindful awareness during daily activities like cooking, walking, or showering. Limiting rumination time by swapping scrolling for reflection or relaxation before bed is another suggestion.
The study was published in the journal PLOS ONE. It adds to a body of research exploring the relationship between sleep patterns and mental health. Other studies have examined how circadian rhythm disruptions can affect mood disorders. The findings suggest that while sleep timing may influence mood, it is not a fixed outcome. By prioritizing quality rest, mindfulness, and a gentle daily structure, individuals may be able to improve their emotional balance.
