An extensive Finnish study covered the sleep and health data of more than 18,000 Finns. Data were obtained from three questionnaires.
Evening are more likely to have depressive and anxiety symptoms, notes a new University of Helsinki researchers Ilona Merikannon and Timo Partosen midwife research.
Symptoms of mental health problems, their diagnoses, and hospitalization were also more common among evening sleepers when viewed through the circadian rhythm.
Inadequate sleep played a major role in the mental health problems of evening sleep, but it did not explain all the connections between mental health and circadian rhythm.
Evening has previously been linked to depression and a variety of sleep problems, such as insomnia, sleep deprivation, and so-called social jetlag.
This social time difference stress means that the internal clock of the evening crochet rotates at different times than the surrounding society, which is largely built on the terms of morning crochet.

According to new and many previous studies, depression and insomnia interact, each reinforcing the other and increasing the risk of contracting the other.
Research according to more than a quarter of the most active people in the evening said they almost never get enough sleep.
In the wake of the morning, only about one in ten complained the same.
In the study, people were divided into four castes based on the surveys: evening crochet, evening crochet, morning crochet, and morning crochet.
However, the connections are diverse and complex. Understanding them, researchers say, is important to better prevent problems caused by the circadian rhythm of the evening. This could ease the pressure on society and health services from the problems.
In the evening there were other mental health problems more often requiring hospitalization based on the study.
Depression episodes were the most common, but bipolar disorder, stress-related problems, neurotic thoughts, and somatic disorders were also more common.
In them, people have physical symptoms, such as pain, without any observed physical illness.
Evening crochetes, and especially evening crochetes that didn’t get enough sleep, also more often felt like they weren’t interested in anything. They were more likely to have antidepressant medication.
In the study it also emerged that parents ’diagnosis of depression is related to their children’s inadequate sleep.
The researchers found it noteworthy that those who slept enough also experienced depressive symptoms.
According to the study, evening naps were also on average younger and more likely to be in working life, while a larger proportion of morning naps were of retirement age.
More than a third of the evening naps were also highly educated, while only less than a fifth of the morning naps reported the same.
Research the sample was 18,039 Finns who had responded to three different surveys.
These are the Finriski Survey of the Department of Health and Welfare of 2007 and 2012 and the FinHealth Survey of 2017.
The studies were questionnaires in which participants determined for themselves whether there were more evening or morning people and reported their average amount of sleep themselves.
In addition, information on diagnoses, hospital care, and health information was collected for the study from THL’s treatment notification system, Hilmo.
