New study Emotional disorder journal The interruption of daily activities and optical exposure patterns is related to the increase in the risk of depression. The researchers analyzed more than 6,800 American adult data and found that people with greater unstable rhythms, activities and light exposure were more likely to experience depressive symptoms. On the other hand, people with more consistent daily patterns were quite low risk of depression.
This study was carried out to better understand how the body’s natural daily confusion contributes to mental health problems. Previous studies have shown that people with depression often have an internal clock disorder that controls irregular sleep cycles, daytime activities, and one -cycle rhythm, that is, sleep, alarm and 24 hours.
However, most previous studies focused only on one aspect of these daily patterns, such as sleep duration or night lighting exposure. Researchers wanted to explore various aspects of daily rhythms, including activity levels and light exposure, to see how stability and fluctuations were related to the risk of depression. Given the increasing prevalence of depression and the interruption of daily rhythms, they aimed to provide insights to provide information to future prevention and treatment strategies.
To conduct research, researchers analyzed data in the National Health and Nutrition Examination Survey, which was collected between 2011 and 2014. A total of 6,852 adults were included in the analysis. Participants wore both old wrists for seven consecutive days to record both movement and light exposure.
Using this data, the researchers evaluated the three main aspects of the daily rhythm. That is, consistent stability (measurement of a consistent method of human activity and light exposure patterns every day), a series of volatility (measurement of sculpted and irregular methods throughout the day) and relative amplitude (measure the intensity of everyday rhythm and compare the most active period). Depression symptoms were evaluated using patient health questionnaire -9, a screening tool widely used for depression symptoms.
The results showed a strong connection between daily rhythm and risk of depression. Those who have a highly variable volatility, which fluctuates so much that activities or light exposure are unpredictable all day long, were much more likely to experience depressive symptoms. In contrast, people with high daily stability and relative amplitude have a clear difference between more regular and predictive daily life and activity and inactive periods. The risk of depression was much lower.
Specifically, individuals with the highest rhythm stability have significantly reduced the possibility of depression compared to those with the most irregular rhythms. The result was consistent depending on the stop active rhythm (daily exercise pattern) and the light exposure rhythm, which suggests that maintaining a stable and structured daily pattern in both areas may be important for mental health.
The study also confirmed the difference in how these factors affect the people of other groups. Young adults are particularly sensitive to fragmentary activity patterns, while men are more influenced by irregular light exposure rhythm than women. In addition, people with low lower body mass index appear to have more benefits of strong light exposure rhythm in terms of reduction in depression. This finding suggests that the relationship between daily rhythm interruption and depression can vary depending on demographic and biological factors.
Despite its strengths, there are several limitations in the study. Because it is a cross -sectional area, it was not possible to determine whether the rhythm interruption caused depression or whether depression led to a more irregular daily pattern. In addition, this study depended on the seven -day monitoring period, which may not be able to fully capture the long -term pattern in the personal daily rhythm. The use of its own depression scale also introduces the possibility of reaction bias.
Future research can be used to explore these associations using longitudinal research to track changes in daily rhythms and mental health over time. It would be worth to investigate whether mediation, which stabilizes daily activities and light exposure, can reduce the risk of depression.
