A recent study suggests a person’s natural sleep timing, known as their chronotype, may have a strong link to their emotional state. Researchers found that people who are naturally night owls reported higher levels of depressive symptoms compared to early risers.
The study, which followed more than 500 university students, identified several factors that may explain this connection. Evening types tended to have lower sleep quality, including inconsistent bedtimes. They also reported higher alcohol intake, particularly on late nights out, and engaged in more rumination, which is repetitive negative thinking.
A key finding involved mindfulness. The researchers measured a specific skill called “acting with awareness,” which is the ability to stay present without judgment. Morning types scored higher in this area. The study suggests that better sleep supports clearer focus and emotional regulation, which may help early risers avoid spiraling into negative thoughts.
For night owls, the combination of less structure, more fatigue, and fewer mindful moments during the day appeared to be a pathway to more depressive symptoms. The researchers concluded that it is not just the bedtime hour that matters, but the lifestyle habits that often come with it.
The good news is that mindfulness can be trained. Practices such as meditation, journaling, and setting aside intentional screen-free time before bed can help strengthen awareness and quiet the mind. The study indicates that small shifts in routine can help support mood without requiring a person to completely change their natural chronotype.
Experts recommend aiming for a consistent bedtime and wake time within an hour each day. Reducing alcohol intake, especially close to bedtime, and practicing mindful awareness during daily activities like cooking or walking may also help. Limiting time spent on rumination and swapping late-night scrolling for relaxation are other suggested steps.
The study was published in the journal PLOS ONE.
