Introduction
Impacts on human behavior are relevant when changes in the routine of individuals occur, requiring changes in habits and ways of relating, especially when conditions of isolation are imposed. Pandemics and epidemics can affect people's physical and emotional health and disrupt society, usually resulting in a high level of psychological distress and psychosocial maladjustment [1].
Social isolation tends to provoke psychological reactions, such as increased levels of anxiety, stress and irritability, propitiate the appearance of fears (based on real or subjective information) and confused thinking, affecting negatively the individual's ability to make coherent decisions [2]. The impacts of social isolation on physical and mental well-being are well known. Isolation, loneliness, among other behaviors and feelings, tend to affect individuals as well as those around them, and this is especially the case during the COVID-19 pandemic [3]. In terms of commuting limitations, professional activity in the Home Office modality has become "savior" of jobs, companies, businesses, ensuring continuity of work, remotely, even though not all people have ideal conditions to work at home. The lack of these conditions can, over time, have consequences on human behavior and cause changes in the general well-being of the subjects.

Physical impacts
Digital Ergonomics needs to be observed, as physical damage related to improper postures and incorrect furniture when using devices from the digital world at home, can cause damage [4]. The improper handling of computers, cell phones, tablets, among others, has favored the appearance of pathologies and functional physical limitations that are being observed more frequently in medical offices [5]. The phototoxicity of violet light from digital devices can lead to progressive degeneration of the macula, a noble area of vision, which can cause irreversible damage to individuals exposed continuously and prolonged to this luminosity [6].
Loneliness and social isolation are living conditions that can increase the likelihood of mental disorders such as depression, anxiety, substance use and cognitive decline [7]. Loneliness shakes people's ability to self-regulate and represents the pain of feeling alone [8]. Working from home office requires constant evaluation in all aspects. We must observe if the individual is able to withstand the repetition of work at home, daily, the absence of colleagues to talk in person, in addition to the feeling of disconnection with the organization or group to which he belongs. It is possible to lose control of time, due to not sharing it with other people, aggravated by the excessive use of digital technologies, reinforcing the solitary character of the home office, which can lead to behavioral changes harmful to health. The opposition between coexistence and isolation is intensified by the role of new communication technologies and social networks that fix the individual in front of screens [9].

Food compulsion
Eating disorders are a group of conditions characterized by persistent disturbances in food or behaviors related to it, which result in changes in the consumption or absorption of food, impairing physical health and psychosocial functioning [10]. Home office workplaces individuals too close to the refrigerator and pantry and, being at home, requires a lot of determination to stick to mealtimes, in choosing what to eat and in what quantities. It is really surprising that we use ice cream and other fatty foods when we are sitting at home feeling totally alone in the world [8]. The home office can be a reinforcing or revealing vector of eating disorders due to one of its characteristics, which is isolation in the development of work.
