Researcher Dr Daryl O’Connor explains: “Women who work long hours eat more high fat and high sugar snacks, exercise less, drink more caffeine and, if smokers, smoke more than their male colleagues,” he points out. “While for men, working longer hours has no negative impact on exercise, caffeine intake or smoking.”
While many women adopt unhealthy behaviours in response to working long hours, researchers believe that, in one respect, working long hours has an equally beneficial effect for both men and women. “The one clear positive impact of working long hours for both sexes is that alcohol consumption is reduced,” Dr O’Connor points out.
These findings are part of a wider study conducted by psychologists from Leeds University into the effects of stress on eating. “Stress disrupts people’s normal eating habits,” Dr O’Connor suggests. “Stress causes people to opt for unhealthy high fat and high sugar snacks in preference to healthier food choices. Also people under stress eat less than usual in their main meals including their vegetable intake but shift their preference to high fat/high sugar snacks instead.”
In this study, researchers examined the stress caused by minor events, or hassles, both in and outside work such as having an argument with a colleague or friend, a meeting with your boss, giving a presentation at work, missing a deadline or even losing your keys. Findings show that those who experienced one or more such hassles during the day reported consuming significantly more between-meal snacks than usual but fewer portions of vegetables, not fruit, and a smaller main meal.
Of the different types of stressors, it is mental rather than physical stress that leads people to snack. Researchers categorized daily hassles into four types: ego-threatening, for example, giving a presentation; interpersonal, for example, an argument; work-related, for example, a meeting with your boss and physical, for example, a severe headache or feeling in danger. And while ego-threatening, interpersonal and work-related hassles lead people to snack more, physical stressors actually lead people to snack less.
Moreover, under stress, certain types of people are more likely to snack than others.
“Those most at risk of snacking under stress are best described as ‘emotional eaters’,” Dr O’Connor points out. “These individuals have higher levels of vulnerability and tend to turn to food as an escape from self-awareness. In other words, when they feel anxious or emotionally aroused or negative about themselves, they try to avoid these ‘negative’ feelings by turning their attention to food.”
“Our findings are disturbing in that they show stress produces harmful changes in diet and leads to unhealthy eating behaviours,” argues Dr O’Connor. “An overwhelming body of evidence shows the importance of maintaining a balanced diet, including eating a low fat diet and five portions of fruit and vegetables a day, in terms of reducing risk of cardiovascular disease cancer risk.
“Yet our study points to a clear link between stress and a tendency to eat more unhealthy snacks and consume fewer vegetables and less of a balanced main meal.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
