Disrupted body clock risks mental health issues

Disrupted body clock risks mental health issues

Individuals with a history of disrupting their body's natural rhythm - working night shifts, for example, or suffering repeated jetlag - also tended to have a higher lifetime risk of mood disorders, feelings of unhappiness, and cognitive problems, the researchers found.

Sticking to a normal daily rhythm - being active during the day and sleeping at night - can have more benefits than you might expect.

Messing with your body clock - or circadian rhythms, if you prefer long words - seriously increases your risk of mood disorders, the University of Glasgow researchers found.

These disturbances to the body's internal clock, characterised by increased activity during rest periods and/or inactivity during the day, are also associated with mood instability, more subjective loneliness, lower happiness and health satisfaction, and worse cognitive function.

The scientists studied people's circadian rhythms, which control functions such as immune systems, sleep patterns, and the release of hormones, to measure the daily rest-activity rhythms, also known as the relative amplitude. Disruption of the internal body clock can put you at raised risk of mood disorders.

For the study, researchers measured body clock disruption on 91, 000 middle aged people using wearable monitors.

They are also likely to feel more lonely and less happy, the study revealed.

The senior opened the day with a 1-under 35 on the front nine and finished with par on each of his final six holes. In 20 par 3 holes played collectively on Tuesday, FSU strung together five birdies, just one bogey and 14 pars.

Around one in 25 participants were about as active during the day as they were at night.

"Circadian disruption is reliably associated with various adverse mental health and well-being outcomes, including major depressive disorder and bipolar disorder", the authors write.

Researchers in the United Kingdom made the conclusion by studying the circadian rhythm: our waking and sleeping patterns throughout the 24-hour sleep cycle.

Professor Daniel Smith, Professor of Psychiatry and senior author, said "This is an important study demonstrating a robust association between disrupted circadian rhythmicity and mood disorders".

The findings have significant public health consequences, particularly for those who live in urban areas, where circadian rhythms are often disrupted due to artificial light, according to Smith.

Writing in a linked Comment, Dr Aiden Doherty from the University of Oxford in the UK agrees: "Although the UK Biobank is one of the most important medical resources worldwide, the study population (median age at baseline of 62 years, IQR 54-68 years) is not ideal to examine the causes of mental health, given that 75% of disorders start before the age of 24 years".
