Disruption of Circadian Rhythm Negatively Impacts Mental Health

Lower relative amplitude was also found to be reliably associated with greater mood instability, higher neuroticism scores, more subjective loneliness, lower happiness and health satisfaction, and slower reaction time (an indirect measure of cognitive function).

Dr. Laura Lyall, the research's lead author, said that the team had found a "robust association" between the disruption of circadian rhythms and the mood disorders.

The researchers found that maintaining a healthy internal body clock, which basically means staying more active during the day and sleeping properly at night, has a positive impact on the overall health of a person.

A disrupted body clock has been linked to an increased risk of developing mental disorders, including depression and bipolarity, in a new study.

The scientists examined people's circadian rhythms, which control functions such as sleep patterns, immune systems and the release of hormones, to measure daily rest-activity rhythms, also known as relative amplitude.

"But it's not just what you do at night", he said, "it's what you do during the day - trying to be active during the day and inactive in darkness", he told.

The results held true even after adjusting for a wide range of influential factors including age, sex, lifestyle, education, body mass index, and childhood trauma.

He added: 'The circadian system undergoes developmental changes during adolescence, which is also a common time for the onset of mood disorders.

Researchers analysed activity data in more than 91,000 participants aged 37-73 from the UK Biobank general population cohort to obtain an objective measure of patterns of rest and activity rhythms.

"This is important globally because more and more people are living in urban environments that are known to increase risk of circadian disruption and, by extension, adverse mental health outcomes". "I don't think it's unreasonable to say this is another piece of evidence that might suggest we should all be more mindful of our natural rhythms of activity and rest", Professor Smith explained.

The study, published Tuesday in the journal The Lancet Psychiatry, looked at disruptions in the circadian rhythms - or daily sleep-wake cycles - of over 91,000 adults in the United Kingdom.

A new study revealed that there was a connection between biological clock disruption and increased risk for mental health issues such as depression and bipolar disorder.

This study was funded by the Lister Institute of Preventive Medicine.
