Stress is part of everyday life, it is a reaction of the body to strong mental, physical or psychological demands where the organism mobilizes all available forces and energies to cope with the situation. This mechanism has been programmed into the human genome since time immemorial. Bodies are designed with a set of automatic responses to deal with stress: fight or flight effect. When a person realized that he or she is stressed, they will have a stress response which is a rapid and automatic process [1]. Today’s life rhythms and demands are often challenging and require intense physical and psychological efforts in order to be sustained [2]. It affects people differently and individuals differ in their stress vulnerability. The effect of stress includes physiological, emotional, cognitive, and behavioral change [3].

An individual person reacts to physical and mental strain by activating interconnected neuroendocrine circuits. Neuroendocrine circuits governing energy balance and stress regulation [4]. This response allows the body to face and deal with the challenge and re-establish the homeostatic equilibrium. If the individual perceives a harmful stimulus as too intense, or its duration as too long, he may fail coping with it, and incur maladaptation. In this case, the stress response does not resolve into a state of balance (either similar or new, i.e., adapted, compared with the state before stress hits), neuroendocrine parameters remain altered, and illness may ensue [2]. Today, most of the time, the pathophysiological complications of disease arise from stress and the subjects exposed to stress, e.g., those that work or live in stressful environments, have a higher risk of many health disorders. Stress can be either a triggering or aggravating factor for many diseases and pathological conditions [1].

The study was conducted to investigate and compare the levels of stress experienced by office employees before and after a short-term stress-reducing intervention and to provide new insights for possible and practical stress-reducing measures.

The eight week study, carried out in March/April 2020, is a quasi-experimental study with pre-test and post-test that was approved by the Board of UEFA—the Union of European Football Associations—who wants to reassure their employees that the board is aware of their potential stress level and has decided to share with them on how to reduce stress level in the workplace with the help of an anti-stress campaign onsite. Selected participants are all volunteer (subjects = 68). The campaign was advertised on the UEFA Health Website. Participants were required to be 21 or older, able to complete the eight week workshop/online process, and able to complete study data collection forms online. Participants were excluded if they couldn’t guarantee to attend the intervention on a regular basis (minimum seven weeks), were on stress medications, or had previously participated in a stress reduction program (less than 1 year).

The research instrument was an eight week campaign of eight stress-reducing specific workshops and online messages:

1) Drink plenty of water [32] [33];

2) Proper breathing and meditation [34] [35] [36];

3) Keep moving/exercise [37] [38] [39];

4) Sunshine and Vitamin D [40] [41] [42];

5) Get enough good sleep [43] [44] [45];

6) No stress when eating a healthy Diet [46];

7) Laughter protects against stress [47] [48];

8) Take time for you/Hobbies [49].

Note: the eight selected stress-reducing intervention topics have all been examined in many studies, were easy and problem-free to carry out, and were well received by the participants (Description/details see Annexe 1).

Stress levels (using questionnaires) were collected at week 0 (pre-test) and week 8 (post-test). To collect data, DASS (Depression, Anxiety, Stress, Scale) questionnaire was used, the international scientific recognized self-report scale designed to measure the negative emotional state of depression, anxiety and stress composed by a 42-item questionnaire. In the present UEFA study, stress was the only concern, hence, the DASS questionnaire was shortened by disregarding the anxiety and depression parts. The stress scale (14 items) is sensitive to levels of chronic non-specific arousal. It assesses difficulty relaxing, nervous arousal, and being easily upset/agitated, irritable/over-reactive and impatient (Annexe 2). As for working conditions, the Likert scale was used, a psychometric scale commonly involved in research that employs questionnaires to measure attitudes or opinions, widely used as an approach to scaling responses in survey research, where respondents are asked to rate items on a level of five agreements: strongly agree; agree; neutral (neither agree/nor disagree); disagree; strongly disagree (Annexe 2). For statistical analysis, the obtained data were analyzed using SPSS for Windows 20. According to the established normality, paired sample t-test will be used for comparing the results before and after the intervention. The threshold of significance was set at p < 0.05.

The result in Table1 described the participants’ characteristics in week 1 before the health campaign was given to participants, and week 8, after the health campaign was given to participants. In week 1, the total participants were 68. But after 8-week follow up the participants became 43. The drop of participants can be explained by the sudden Covid-19 situation and the postponement of UEFA EURO 2020 activities. Overall, both in week 1 and week 8, the percentages of participants’ characteristics were higher in the same categories, except the length of work. In week 1 and week 8 the percentage of female participants was higher than male participants (72.1% and 74.4%). The highest age percentage was in group 30 to 40 (47.1% and 55.8%). But the age group 50 to 64 decreased in week 8 until 5% (16.2% became 9.3%). The mean and median height of participants showed the same result in week 1 and week 8. But for the weight, the mean and median of participants in week 8 were lower than in week 1. Both in week 1 and week 8, most of the participants were single (57.4% and 58.1%) and had last education in college or university (83.8% and 88.4%). For the participants’ length of work, there were more than half of participants who work less than 1

year did not participate in week 8. That made the percentage in week 1 was highest in participants who already work in UEFA less than 1 year (38.2%) while in week 8 was highest in participants who already worked for 2 - 5 years (41.9%). More than 80% of participants were full-time employment both in week 1 and week 8 (83.8% and 81.4%).

Table 2 reported the participants’ working conditions before the health campaign was given. As seen in Table 2, from 43 participants, 44.19% strongly agreed that the working conditions are very pleasant and the other 44.19%

disagreed. Most of them strongly agree that they had a heavy workload in general (32.56%), had good colleague support (53.49%), did not feel any job insecurity (34.88%), and had good work-life balance (37.21%).

Table 3 revealed that 39.53% of participants consider the COVID-19 situation to sometimes prevent them from doing their job correctly and followed by 34.88% that answered it never. After the participants got the health campaign, 53.49% of them answered that the campaign sometime will help them to deal better with the stressful situations in the future.

As for stress perception, 13 of 14 items of stress perceptions had an increasing number of participants who answer “never” from pre-test to the post-test result (Table 4). The item “I felt that I was rather touchy” had the same percentage in “never” answer pre and post. But the percentage of participants who often felt that they were rather touchy decreased and moved to “sometime”. The important point here, the result showed there were 7 items that no one participant answered “almost always” in the post-test after before in the pre-test there were participants who answered, “almost always”. The items were “I tended to overreact situations”, “I felt myself getting upset rather easily”, “I found myself getting impatient when I was delayed in any way (e.g., lifts, traffic lights, being kept waiting)”, “I found it hard to wind down”, “I found it difficult to tolerate interruptions to what I was doing”, “I was intolerant of anything that kept me from getting on with what I was doing”, and “I found myself agitated”.

Figure1 showed the difference stress perception score of participants before and after they got a health campaign. There were 12 participants who had an increased score number in the post-test with the highest increase was 12 in participant number 13. And 2 participants had the same score in pre- and post-test, participants number 2 and 43. The rest of the participants showed that their score of stress perception decreased after they got a health campaign. The highest decrease was in participants number 14 with the difference score 21, followed by numbers 29 and 36 with the different scores 20 and 18.

The Kolmogorov-Smirnov with Lilliefors Correction Test and Shapiro-Wilk Test to test the normality distribution of difference score of stress perception between pre- and post-test on health campaign showed p-value more than 0.05. It meant the distribution was assumed normal. That was why the analysis of the

mean difference between pre- and post-test used a paired-sample t-test.

The test result in Table 5 revealed that there was a significant difference mean of stress score before and after the participants got a health campaign with the p-value less than 0.001. The mean difference was 4.18. It meant after the participants got a health campaign the mean of the stress score decrease 4.18.

Today, stress has become a recognizable mode of reaction in an increasingly difficult social and collective climate. There is a considerable increase in medico-psychological complaints related to stress and the interest of employers and societies has proportionately increased as a result. The degree of absenteeism in the workplace could be interpreted as an index of stress. Thus, what we are faced with today is, quantitatively, a real increase in stress-related disorders in the professional framework. Whilst, today, treating mental health problems often requires professional medical intervention, the health campaign amongst office workers at UEFA has shown that when it comes to self-care, the process of forming healthy habits and making positive changes to the daily routine, and also improving emotional and physical health as a way to manage and reduce stress, is possible. The more that people take an active role in helping themselves and making positive improvements in their lifestyles, the better their chances of feeling better and staying well.

The present study showed that the intervention of simple daily lifestyle measures significantly reduced stress levels or stress symptoms and could therefore be considered as complementary medicine. The therapeutic effects of comprehensive lifestyle measures, such as drinking enough water, practicing proper breathing and meditation, taking regular exercise, getting enough sleep, not stressing when eating, taking sufficient time to relax, enjoying a social life, getting sufficient levels of natural sun (Vitamin D) or cultivating an exciting hobby, have been confirmed in previous studies, that endorse yoga practice [39], physical exercise [37], meditation [50], or breathing exercises [35]. This study suggests complementary simple and practical daily measures that are also worthy of inclusion in preventive guidelines.

Regarding the limitation of the study, the heterogeneity of the eight different lifestyle measures makes it difficult to recommend any specific practice. The effect is more likely to be in the sum of all measures and/or in the individual preference for one or the other weekly intervention. It should however be noted that all participants voluntarily took part in the study and were self-motivated to do so.

The intervention at the workplace of office employees at UEFA, the United European Football Association, has shown that simple stress-specific lifestyle behaviors, wrapped up in weekly workshops and online messages over a period of eight weeks, significantly reduced stress and stress-related conditions in office workers and improved positive dimensions of mental health and stress-related behaviors. The selected stress-reducing topics were easy and problem-free to carry out and were well received by the participants. In this regard, the eight-week stress campaign at UEFA, the Union of European Football Associations in Nyon/ Switzerland, was statistically relevant and successful in its aims. This campaign may be applicable to office workers of any type of other similar organizations or companies. Further studies to ascertain the long-term effects of practicing these simple and practical lifestyle measures and the underlying biological mechanisms leading to their stress reduction effects should be conducted.

The authors’ thanks go to UEFA, the Union of European Football Associations, who gave them the opportunity to run this campaign. And last, but not least, the authors don’t want to forget all the participants who persevered despite the difficult Corona situation.

The eight selected stress-reducing intervention topics have all been examined in many studies, were easy and problem-free to carry out, and were well received by the participants.

For participants’ stress perception, the results revealed a significant difference mean of stress score before and after the intervention for most of them. The therapeutic effects of simple and practical lifestyle measures to fight stress, like drinking enough water, proper breathing, regular exercise, enough sleep, no stress when eating, taking sufficient time to relax, enjoying social life, sunbathing (Vitamin D) or cultivate an exciting hobby have been confirmed in many other studies. Overall, there is current evidence for their therapeutic effectiveness.

1) Drinking enough water is a simple measure to specifically prevent stress. Hypernatremia is a common electrolyte problem that is defined as a rise in serum sodium concentration to a value exceeding 145 mmol/L. It is strictly defined as a hyperosmolar condition caused by a decrease in total body water (TBW) relative to electrolyte content [32]. Hypernatremia most often occurs in people who are stressed. Current results, in agreement with previous studies, strongly suggest that acute hypernatremia limits stress responding [33].

2) Slow and deep breathing activates the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers. The parasympathetic nervous system acts like a brake. When the parasympathetic nervous system is activated, it produces a calm and relaxed feeling in the mind and body [34]. People can learn to trigger their parasympathetic nervous system by slow and deep breathing to immediately reduce their sense of anxiety and stress [35]. The psycho-physiological changes in brain-body interaction observed in most of meditative and relaxing practices rely on voluntary slowing down of breath frequency [34] [51]. Slow breathing techniques seem to interact with the cardio-respiratory system by increasing HRV and RSA, suggesting thus a strong involvement of the parasympathetic nervous system [36] [52].

3) According to many studies, regular exercise works as well as medication for some people to reduce symptoms of stress, and the effects can be long lasting. One vigorous exercise session can help alleviate symptoms for hours, and a regular schedule may significantly reduce stress over time. The benefits of aerobic exercise like walking, running, dancing include an increased heart rate. When your heart rate is accelerated, your body releases endorphins, natural opiates that make people feel good and relaxed [37] [53]. In recent years, several medical and scientific studies on yoga exercises proved it to be very useful in the treatment of stress symptoms [38]. Yoga means the unity of mind and body, which has been used in Eastern Societies since thousands of years ago and has recently received much attention from Western countries [54]. Yoga has an effective role in reducing stress as well as beneficial effects on many other health conditions [39] [55].

4) Study after study indicates the direct link between Vitamin D levels and mental health is so strong. A positive association between Vitamin D levels and elevated serum cortisol has been observed [40] [56]. A 2015 review study reports that people with symptoms of stress, anxiety and depression had lower levels of calcidiol, a byproduct of vitamin D breakdown, in their bodies [41]. Today’s scientists have come to the recognition that exposure to the ultraviolet radiation (UVR) in sunlight, the natural source of Vitamin D, has beneficial effects on human health. Direct sunlight is a dominant predictor of anxiety and stress; indirect sunlight is a dominant predictor of depressed mood [57]. Exposure to natural elements in the workplace will be positively related to employees’ mental health—lower depressed mood, anxiety, stress—and work attitudes like higher job satisfaction and organizational commitment [42].

5) Sleep is important to manage stress. Stress awareness is associated with short sleep duration. Numerous studies focus on the need for stress management to improve sleep. The main finding of these studies is that short sleep duration might be associated with an increased odds ratio for perceived stress compared to adequate sleep duration [43]. A good night’s sleep makes people able to tackle the day’s stress more easily [44]. When people are tired, they are less patient and more easily agitated, which can increase stress [45].

6) No stress when eating: Avoid dealing with a stressful situation when eating. Enjoying a healthy diet in a quiet environment can reduce the negative effects of stress on our body. A healthy diet, enjoyed in peace, builds a solid, more enduring foundation for our body by reducing oxidation and inflammation [46].

7) Laughter induction initiates the fight-or-flight stress response. However, approximately 20 minutes after laughter, physiological measures such as heart rate, blood pressure, and muscular tension, drop below baseline levels. Currently, research is indicating that the physical act of laughing, laughter’s physiologic effects, even without humor, is linked to chemical changes in the body that potentially reduce stress [47]. Laughter can alter dopamine and serotonin activity. Furthermore, endorphins secreted by laughter can help when people are stressed or uncomfortable in a depressed mood. Laughter therapy is a noninvasive and non-pharmacological alternative treatment for stress and depression [48].

8) Furthermore, research shows that people with hobbies are less likely to suffer from stress. Activities that get people out and about can make them feel happier and more relaxed. This may be another interesting and essential part of balancing out the stress people experience [49].

DASS (Depression, Anxiety, Stress, Scale) is an international scientific recognized self-report scale designed to measure the negative emotional state of depression, anxiety and stress composed by a 42-item questionnaire. It was created on a sample of 2914 Australian adults in 1995.

In the present UEFA study, stress is the only concern, hence, the DASS questionnaire is shortened by disregarding the anxiety and depression parts. The stress scale (items) is sensitive to levels of chronic non-specific arousal. It assesses difficulty relaxing, nervous arousal, and being easily upset/agitated, irritable/over-reactive and impatient.
