A major new study published in medical journal The Lancet Psychiatry reveals a link between a disrupted body clocks and bi-polar disorder.
It found people who were more active a night were at greater risk of developing mood disorders and depression.
Scientists recorded data from more than 91,105 people wearing a sleep detecting device on their wrist for seven days to see how sleep — or lack of sleep — affect their mood.
The researchers from University of Glasgow examined sleeping patterns, body temperature, immune systems, hormones to measure body rhythms.
Can we gain a better understanding of the biology of #mentalhealth by looking at our #bodyclock? Hopefully my #PhD research can help #UofGImpact #uofg #uofgmvls #ukbiobank #mrc— Amy Ferguson (@amyferguson93) May 9, 2018

They concluded that body clock disruptions were reliably associated with depression and bipolar disorder.

Professor Daniel Smith, senior author of the paper, told The Times: "It's not just what you do at night, it's what you do during the day — trying to be active during the day and inactive in darkness."
"This is an important study demonstrating a robust association between disrupted circadian rhythmicity and mood disorders," says Professor Smith.
