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.”

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
