Poor Sleep May Make it Harder to See Positive Side

The researchers found this to be true in those with lower levels of sleep efficiency

Researchers have found that poor sleep may affect a specific region of the brain known to be involved in regulating negative emotional responses, especially in those suffering from depression and anxiety, thereby further restricting their ability to see things in a positive light.

This area of the brain, the dorsal anterior cingulate cortex, may have to work harder to modify negative emotional responses in people with poor sleep who have depression or anxiety, said the study published in the journal Depression and Anxiety.

“Our research indicates sleep might play an important role in the ability to regulate negative emotions in people who suffer from anxiety or depression,” said lead researcher Heide Klumpp, Assistant Professor at University of Illinois at Chicago College of Medicine in the US.

The research team used functional MRI to measure the activity in different regions of the brain as participants were challenged with an emotion-regulation task.

The 78 participants in the study were between ages 18 and 65 and had been diagnosed with an anxiety disorder, a major depressive disorder, or both.

Participants were shown disturbing images of violence — from war or accidents — and were asked to simply look at the images and not to try to control their reaction or to “reappraise” what they saw in a more positive light.

An example of reappraisal would be to see an image of a woman with a badly bruised face and imagine her as an actress in makeup for a role, rather than as a survivor of violence, Klumpp said.

“Reappraisal is something that requires significant mental energy,” she said.

“In people with depression or anxiety, reappraisal can be even more difficult, because these disorders are characterised by chronic negativity or negative rumination, which makes seeing the good in things difficult,” Klumpp added.

Study Reveals Poor Sleep Linked to Genetics

Suffering from sleep disorder? Blame genetics. A new study has found several parts of our genetic code that could be responsible for poor sleep.

Researchers from the Massachusetts General Hospital (MGH) and the University of Exeter identified as many as 47 links between our genetic code and the quality and quantity of sleep.

Among the genomic regions discovered is a gene called PDE11A. The team found that an uncommon variant of this gene affects not only how long one sleeps but also the quality of sleep.

“This study identifies genetic variants influencing sleep traits, and will provide new insights into the molecular role of sleep in humans,” said lead author Samuel Jones from the University of Exeter.

“Changes in sleep quality, quantity and timing are linked to several human diseases such as diabetes and obesity, and psychiatric disorders,” added Andrew Wood from the varsity.

The study, published in the journal Nature Communications, the researchers looked at data from 85,670 participants of UK Biobank and 5,819 individuals from three other studies, who wore accelerometers-wrist-worn devices, which record activity levels continuously.

They found that collectively, the genetic regions linked to sleep quality are also linked to the production of serotonin-a neurotransmitter associated with feelings of happiness and wellbeing. Serotonin is known to play a key role in sleep cycles and is theorised to help promote deeper and more restful sleep.
