Possibility of getting into a mood disorder if the body clock is disturbed

Birth is bornBiological clockIt is thought that it affects the cycle of sleep and behavior. According to the latest study in the UK, if we disrupt this body clock, humans are likely to become mood disorders such as depression and bipolar disorder.

Out-of-Sync Biological Clock Could Be Linked to Depression

Also called "biological clock"Circadian rhythm"Is" in the hypothalamus of the brain "Suprachiasmatic nucleusIt is under the control of the area. With the light of the sun as a clue, the top of the sighting crown grasps the time and relays this information to a place called "peripheral clocks" in the whole body.

However, it may disturb the circadian rhythm by artificial light, night shift, aging, certain diseases, even traveling overseas. And it is suggested that disorder of circadian rhythm may have a bad influence on the mental side.

Medical journal(PDF)The LancetIt was announced that there is a possibility that the circadian rhythm is disturbed and it is likely to become mood disorders such as depression or bipolar disorder in the latest research published in. However, researchers have found that this study is only related to circadian rhythms and mood disorders such as depression and bipolar disorder, and until the circadian rhythm is the cause of depression It is said that it has not been proved.

The study was conducted over the four years from 2013 to 2016 for participants of the 500,000 health information acquisition project conducted in the UK. The number of subjects is the largest survey on circadian rhythms, over 90,000 people. Subjects were instructed to wear an accelerometer on their wrists, measure their exercise status for a week, and then respond to mental health questionnaires. From the data collected by this questionnaire and accelerometer, the relationship between circadian rhythm and mental health was analyzed.

Analysis showed that those with greatly disordered circadian rhythms are more prone to depression or bipolar disorder than others over the lifetime. In addition, people with strong circadian rhythm disorder tend to have a change in mood, a high level of neurosis and loneliness, a tendency to lower levels of happiness and satisfaction with health, It is also known that it is slow.

Mr. Iden Doherty, a senior researcher at Oxford University, acknowledges that circadian rhythm disturbance and mood disorders are closely related and emphasizes that it can not prove that it is the cause of mood disorder . However, we evaluate that the method of using the accelerometer for subjects to judge the disorder of the circadian rhythm can be judged more correctly than the conventional subjective measure of asking the subject "morning or night type" I will.

Since circadian rhythm is known to cause a slight change in puberty and 75% of mood disorders also begin before 24 years old, this new study is aimed at identifying the cause of mood disorders by age group and the potential prevention He provided useful information to plan the strategy, he says.
