Brazil study: Your bedtime may secretly be ruining your mood
New research suggests that a person’s natural sleep schedule may have a stronger link to their emotional health than previously understood. The study, published in a scientific journal, indicates that individuals who tend to stay up late, often called night owls, report higher rates of depressive symptoms compared to early risers.
Researchers monitored over 500 university students for the study. They found that the connection between a late bedtime and mood is not simply about the hours of sleep a person gets. Instead, the study points to a combination of factors often seen in night owls, including lower sleep quality, higher alcohol intake, and a tendency toward repetitive negative thinking, known as rumination.
A key element in the findings was the role of mindfulness. Specifically, the researchers looked at a skill called “acting with awareness.” This is the ability to stay focused on the present moment without being overly critical or distracted. The study found that morning types scored higher in this area. Better sleep may support clearer thinking and emotional control, the researchers noted.
Evening types were more likely to engage in late-night overthinking. However, the study suggests that mindfulness is a skill that can be developed. Practices such as meditation or simply taking time away from screens before bed could help quiet the mind and improve emotional balance.
For those who are naturally inclined to be night owls, the study does not suggest a need to completely change their sleep schedule. Instead, small adjustments could help. The researchers recommend aiming for a consistent bedtime and wake time, keeping them within the same hour each day. Reducing alcohol intake, particularly close to bedtime, was also advised.
Adding moments of mindful awareness to daily routines, such as while cooking or walking, may also be beneficial. Limiting time spent on rumination and replacing late-night scrolling with relaxation activities are other suggestions from the study. The overall message is that sleep timing can influence mood, but it is not a fixed outcome. By focusing on sleep quality and mindfulness, individuals may be able to improve their emotional health.
