Disrupted body clock risks mental health issues

Disrupted body clock risks mental health issues

The findings were found to be consistent even when controlling for a number of influential factors including age, sex, lifestyle, education and body mass index, according to Smith.

"It's a cross-sectional study, so we can't say anything about cause and effect or what came first, the mood disorder or the circadian disruption", said Kristen Knutson, associate professor of neurology at Northwestern's Feinberg School of Medicine, who was not involved in the study.

He added it is advisable to avoid activities that disturb the circadian rhythm after 10pm, but that activities during the day were just as important, giving the example of being outside in the morning during the winter months. It decides your sleeping time in a 24 hour day.

Greater disease risks arising from this disruption have been identified in the brain, pancreas and stress systems.

'Previous studies have identified associations between disrupted circadian rhythms and poor mental health, but these were on relatively small samples'.

The largest study of its kind, involving more than 91,000 people, also linked interference with the body's "circadian rhythm" to a decline in cognitive functions such as memory and attention span. This information was linked to mental health questionnaires to assess symptoms of mental disorders and subjective wellbeing and cognitive function. The participants wore activity monitors for a week which measured how disrupted their body clocks were.

A study of 91,000 people found following your body's natural clock is vital to stay mentally healthy. Those who do not have a greater chance of developing mental disorders

The researchers found that those who did not follow the natural rhythm had a greater likelihood of major depression or bipolar disorder and were also more likely to suffer worse wellbeing such as lower happiness levels.

They were also more likely to feel lonely and less happy. The findings show your body clock is associated with mood disorders. Circadian rhythms occur in plants, animals and throughout biology.

Recently scientist has found that those who have their body clock disturbed by being awake at night risk developing depression and mood disorders.

Unfortunately, a new study says not getting good sleep can take a serious toll on your mental health. According to the study, one of the harmful effects of a disrupted body clock is a higher risk for mental health issues. As the authors note, the circadian system undergoes developmental changes during adolescence, which is also a common time for the onset of mood disorders.

'It might be that the UK Biobank provides the impetus for a resource of a similar scale in adolescents and younger adults to help transform our understanding of the causes and consequences, prevention and treatment of mental health disorders'.
