Every physician has to face patients whose main pathologies are burdened by high and chronic degrees of stress. Sometimes, stress-related symptoms are their main pathology. According to Herbert Benson, who pioneered mind-body research and is founder of the Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital in Boston, stress is the main cause of medical visits in the USA [1].

Therefore, it is of the utmost importance for the healthcare personnel to know origin and consequences of stress and be able to suggest and teach patients some possible techniques for its management.

Stress comes from a well-understood mechanism which aims at preparing the body to a change, that is something that discards the homeostasis (like the attack of a beast or a work stressor). Walter Cannon called this mechanism “fight or flight response” and identified the activation of sympathetic nervous system and the release of epinephrine as its main triggers [2]. After the change occurs (the beast was beaten or the work issue was resolved), the homeostasis is restored. In this view, stress is useful, and even necessary, to face changes in life. In the best cases, homeostasis is restored at a higher level, allowing the individual to obtain an evolutionary advantage [3].

However, if the stress persists too long, several systems are damaged: hippocampal, endocrine, and central nervous system circuits are deregulated, resulting in worsened cognitive and general health conditions [4]. In addition, the secretion of corticotropin-releasing hormone (CRH), norepinephrine, and cortisol

In addition, the immune system produces cytokines, responsible for the onset of fatigue, nausea, headache, and other pains [3]. Together, all these negative signs are called “sickness syndrome”.

Both sides of the stress coin are well caught by Yerkes-Dodson law, represented in Figure 1 [5,6].

Eustress is helpful to improve the performance, but too high or too prolonged levels of stress are called “distress” and are responsible for the sickness syndrome.

Some of them are more often referred to as “medically unexplained symptoms” or MUS [8]. Several studies showed that 15-30% of patients in primary health care area have MUS, i.e. physical symptoms without evidence of underlying diseases [9]. Frequently, MUS require urgent diagnostic tests and hospitalizations, whose costs burden the already overwhelmed health systems. According to a multicenter study, which analyzed almost 100,000 patients, MUS are reliable indices of chronic stress and inflammation [10].

It is up to healthcare professionals to agree on a comprehensive action plan with the patient in order to eradicate his/her symptoms [11].

Helping people managing the stress is equivalent to teach the resilience. The resilience is the ability to overcome stress in an adaptive way, maintaining at the same time the normal psychological and physical functioning [12-14].

Resilience may be improved through the development of life skills. The World Health Organization (WHO) defined “life skills” as «abilities for adaptive and positive behavior that enable individuals to deal effectively with the demands and challenges of everyday life» [15]. According to WHO, life skills are:

These qualities could be better developed by ad hoc programs targeting children and teenagers, which have been prepared by WHO itself and are recommended in schools.

Among the most important steps towards the management of stress, there is a healthy lifestyle, which includes mainly healthy diet and physical activity.

Chronic stress may alter glucose metabolism, promote insulin resistance, affect leptin, ghrelin and hypothalamic neuropeptides [16], and trigger the secretion of glucocorticoid hormones, which favor the deposition of abdominal fat [17]. In addition, the rewarding properties of comfort food may help people feel better. On the other side, scientific evidence underline that a healthy diet may help in the treatment of several pathologies.

However, physicians, before prescribing a diet, should help patients know their own targets, rhythms, limits, teaching also how to relax and reward themselves in order to reduce stress in a natural way. Otherwise, even if an energy-restricted diet is prescribed, metabolism slows down and results in weight gain (thrifty metabolism [18]).

The exercise results in an increase in the volume of muscle fibers and in the ability to manage stress, as it increases glycogen and therefore the energy available. In addition, it may trigger endorphin release, thus contributing to the creation of the “flow” [19], a mental status of deep well-being and pleasure, known to be related to the development of resilience [20]. Finally, physical activity delays cell senescence [21] and results in the release of brain derived neurotrophic factor (BDNF), which increases cerebral plasticity [22].

Also in this case the physician prescribing physical activity to stressed patients should be careful while suggesting type, timetable, and mode, since they have to be chosen according to the individual’s preferences, body composition, and circadian rhythms, in order to avoid the development of further stress.

Lifestyle Medicine deals exactly with the dissemination of the knowledge regarding the importance of exercise, healthy diet, behavioral change and self-care, and the eradication of unhealthy lifestyles, including also tobacco addiction. Healthy lifestyles have been proven effective in the reduction of all-cause mortality [23]. Several associations and initiatives all over the world promote Lifestyle Medicine [24-29].

Professor Herbert Benson, starting from the known mutual influence between mind and body, pioneered and refined the Mind-Body Medicine, another effective mode to manage stress. Since the increased emotional stress results in the onset and worsening of physical symptoms of malaise and exacerbates clinical conditions, Benson suggested that mind-body therapies have significant therapeutic effects in several pathological conditions, eliciting an intrinsic anti-stress response, which includes a reduction in the sympathetic and cerebral cortical activity [30]. He called this intrinsic response to stress “relaxation response” and found that it can be elicited by prayers (in every religious tradition) and meditative practices.

His colleague Jon Kabat-Zinn chose one of them, Vipassana meditation, and turned it in an appreciated occidental version, called “mindfulness” [31]. Mindfulness

It consists in paying attention on purpose, in the present moment, and non-judgmentally [37]. This technique could be learnt in Professor Kabat-Zinn’s clinic, Center for Mindfulness in Medicine, Health Care, and Society at the University of Massachusetts Medical School [38], but also in several other centers all over the world, as its success was planetary.

Stress may affect also organizations. This phenomenon occurs especially during or before a change. As in individuals, in order to avoid pathological consequences, the organization should be resilient.

The resilience of an organization may be assessed through analyzing protection factors in processes concerning efficacy and efficiency. The WHO developed international standards for the self-assessment [44] in healthcare settings by means of Health Promoting Hospitals & Health Services (HPH) strategy [45], putting in place the Ottawa Charter for Health Promotion [26].

An Italian compendium about standards 1 and 4 focusing on psycoemotional well‑being has been developed [46]. It aims at being used in parallel with the risk assessment and promoting the organizational and personnel empowerment concerning the protection factors of health at work. It comes of a rapid self-assessment model on three levels: top management, staff, and individual.

Although stress is necessary to face changes and obtain goals, its permanence and too elevated levels may negatively affects several aspects of people’s life, influencing also the course of pathologies and determining itself signs and symptoms. However, several techniques to reach a psychological balance can be learnt.

Patients should rely on healthcare professionals able to teach these techniques or to refer them to the most suitable teachers, according to the patient’s nature and preferences.

Similarly, pathological consequences of stress in organizations should be prevented through specific standards for self-assessment developed by WHO.
