The Science of Workplace Wellbeing

Workplace conditions can affect employees at the physical, mental, or emotional level and enhance or harm their well-being. Studies have found differences among occupational groups in the prevalence of obesity, cardiovascular conditions (eg, elevated blood pressure and cholesterol), and other health indicators, including physical activity and diet quality. Work environment can also influence employees’ mental health and stress levels.

University of Oxford research links workplace wellbeing to business performance.

Healthy eating patterns, such as the Mediterranean diet, are associated with better mental health than “unhealthy” eating patterns, such as the Western diet.

The effects of certain foods or dietary patterns on energy, glycaemia, immune activation, and the gut microbiome may play a role in the relationships between food and mood.

Poor nutrition may be a causal factor in the experience of low mood (low mental resilience) and improving diet may help to protect not only the physical health but also the mental health of the population.

Work-related exhaustion and emotional impairment can lower the individual's tolerance to perceiving events as stressful as well as reinforce the stress response, and contribute to difficulties with productivity, effective communication, cognitive function and more. Workers employed in occupations with critical tasks may be more susceptible to exhaustion, emotional strain and poorer sleep due to increased and prolonged work pressure.

Poor sleep of employees has often induced many negative consequences, such as a decline in in-role performance, poor interpersonal relationships in the workplace, a decline in organizational citizenship behaviors, and an increase in unethical workshop behaviors, thereby further negatively affecting the routine work and orderly operation of various organizations.

There is increasing evidence that the composition of the resident bacteria within the gastrointestinal tract can influence the brain and behavior, particularly with respect to cognitive function. Cognitive function encompasses the life-long process of learning, both long- and short-term processes.

The number of individuals experiencing mental disorders (e.g., anxiety and depression) has significantly risen in recent years. Therefore, it is essential to seek prevention and treatment strategies for mental disorders. Several gut microbiota are demonstrated to affect mental health through microbiota–gut–brain axis, and the gut microbiota dysbiosis can be related to mental disorders, such as anxiety, depression, and other mental disorders.
