Getting out of the bed early can keep the blues away : Study

Middle-to-older aged women who are naturally early to bed and early to rise are significantly less likely to develop depression, according to researchers at University of Colorado Boulder and the Channing Division of Network Medicine at Brigham and Women’s Hospital in Boston.

The study, that published in the Journal of Psychiatric Research included more than 32,000 female nurses, explored the link between chronotype, or sleep-wake preference, and mood disorders.

It showed that even after accounting for environmental factors like light exposure and work schedules, chronotype – which is in part determined by genetics – appears to mildly influence depression risk.

“Our results show a modest link between chronotype and depression risk. This could be related to the overlap in genetic pathways associated with chronotype and mood,” said lead author Celine Vetter.

The researchers found that late chronotypes, or night owls, are less likely to be married, more likely to live alone and be smokers, and more likely to have erratic sleep patterns.

After accounting for these factors, they found that early risers still had a 12 – 27 percent lower risk of being depressed than intermediate types. Late types had a 6 percent higher risk than intermediate types (this modest increase was not statistically significant.)

Genetics play a role in determining whether you are an early bird, intermediate type, or night owl, with research showing 12-42 percent heritability. And some studies have already shown that certain genes (including PER2 and RORA), which influence when we prefer to rise and sleep, also influence depression risk.

“Alternatively, when and how much light you get also influences chronotype, and light exposure also influences depression risk. Disentangling the contribution of light patterns and genetics on the link between chronotype and depression risk is an important next step,” Vetter said.

Vetter stressed that while the study suggested that chronotype was an independent risk factor for depression, it did not mean night owls were doomed to be depressed.

“Being an early type seems to beneficial, and you can influence how early you are” she said. “Try to get enough sleep, exercise, spend time outdoors, dim the lights at night, and try to get as much light by day as possible.”

Sudden cardiac arrests are more likely to happen on any day at any time : Study

A new study has showed that sudden cardiac arrests are more likely to happen on any day at any time, challenging previous claims that weekday mornings — especially Mondays — were the danger zones.

Previously heart experts have long believed that weekday mornings were the danger zones for unexpected deaths from sudden cardiac arrests.

“While there are likely several reasons to explain why more cardiac arrests happen outside of previously identified peak times, stress is likely a major factor,” said Sumeet Chugh, a Professor of medicine from the Smidt Heart Institute in the US.

“We now live in a fast-paced, ‘always on’ era that causes increased psycho-social stress and possibly an increase in the likelihood of sudden cardiac arrest,” Chugh added.

Almost 17 million cardiac deaths occur annually worldwide while the survival rate from sudden cardiac arrest is less than one per cent.

For the study, published in the journal Heart Rhythm, Chugh’s team analysed data on 1,535 from the community-based Oregon Sudden Unexpected Death Study between 2004 to 2014, among which only 13.9 per cent died in the early morning hours, the findings revealed.

All reported cases were based on emergency medical service reports containing detailed information regarding the cause of the cardiac arrest.

“Because sudden cardiac arrest is usually fatal, we have to prevent it before it strikes,” Chugh said. “Our next steps are to conclusively determine the underlying reasons behind this shift, then identify public health implications as a result,” he added.

Apart from stress, other contributing factors may be a shift in how high-risk patients are being treated, as well as inadequacies in how past studies have measured time of death caused by sudden cardiac arrest.
