We report from the Do Not Disturb Challenge where 30 volunteers disabled notification alerts for 24 hours across all devices. The effect of the absence of notifications on the participants was isolated through an experimental study design: we compared self-reported feedback from the day without notifications against a baseline day. The evidence indicates that notifications have locked us in a dilemma: without notifications, participants felt less distracted and more productive. But, they also felt no longer able to be as responsive as expected, which made some participants anxious. And, they felt less connected with one's social group. In contrast to previous reports, about two third of the participants expressed the intention to change how they manage notifications. Two years later, half of the participants are still following through with their plans.
Notifications & Stress In addition to negative effects on work efficiency, interruptions can also affect people emotionally. Interruptions in the workplace have been linked to frustration @cite_40 and stress @cite_38 . In the context of notifications, information workers felt significantly less stressed without email @cite_33 , without email notifications @cite_27 , or when checking work email was restricted to 3 times per day @cite_13 . However, work emails no longer reach us at only work. Our mobile devices may notify us about incoming emails at any time, which blurs the boundaries between work and private life @cite_6 @cite_16 . Stress levels were found to positively correlate with the number of mobile phone notifications from, in particular, email clients @cite_19 , which indicates that email notifications are particularly problematic. Mobile phone notifications in general have been linked to inattention and hyperactivity @cite_4 . On the basis of this related work, we hypothesize that the absence of notifications will reduce stress and other negative emotions.

Notifications on mobile phones alert users about new messages, emails, social network updates, and other events. However, little is understood about the nature and effect of such notifications on the daily lives of mobile users. We report from a one-week, in-situ study involving 15 mobile phones users, where we collected real-world notifications through a smartphone logging application alongside subjective perceptions of those notifications through an online diary. We found that our participants had to deal with 63.5 notifications on average per day, mostly from messengers and email. Whether the phone is in silent mode or not, notifications were typically viewed within minutes. Social pressure in personal communication was amongst the main reasons given. While an increasing number of notifications was associated with an increase in negative emotions, receiving more messages and social network updates also made our participants feel more connected with others. Our findings imply that avoiding interruptions from notifications may be viable for professional communication, while in personal communication, approaches should focus on managing expectations. Notifications are the mechanism that mobile applications utilize to let users know that a new message, email, call or similar has been received. Notifications may make a sound, a vibration or modify the app icon in some way. They may make us stop what we are doing, thus interrupting us and having a negative effect on our work. Before defining a cause-effect relation between notifications and their impact on the users' current tasks, first we have to study how users manage notifications. This paper describes the results of a survey on how users react when they receive a notification. The results of this descriptive research show how people are moving from sound to visual notifications, which reflects the ability of people to adapt to new technologies. Desktop notifications are designed to provide awareness of information while a user is attending to a primary task. Unfortunately the awareness can come with the price of disruption to the focal task. We review results of a field study on the use and perceived value of email notifications in the workplace. We recorded users' interactions with software applications for two weeks and studied how notifications or their forced absence influenced users' quest for awareness of new email arrival, as well as the impact of notifications on their overall task focus. Results showed that users view notifications as a mechanism to provide passive awareness rather than a trigger to switch tasks. Turing off notifications cause some users to self interrupt more to explicitly monitor email arrival, while others appear to be able to better focus on their tasks. Users acknowledge notifications as disruptive, yet opt for them because of their perceived value in providing awareness. Limiting the frequency of checking email throughout the day reduced daily stress.Lower daily stress predicts greater well-being (e.g., higher positive affect).The frequency of checking email did not directly impact other well-being outcomes. Using email is one of the most common online activities in the world today. Yet, very little experimental research has examined the effect of email on well-being. Utilizing a within-subjects design, we investigated how the frequency of checking email affects well-being over a period of two weeks. During one week, 124 adults were randomly assigned to limit checking their email to three times a day; during the other week, participants could check their email an unlimited number of times per day. We found that during the limited email use week, participants experienced significantly lower daily stress than during the unlimited email use week. Lower stress, in turn, predicted higher well-being on a diverse range of well-being outcomes. These findings highlight the benefits of checking email less frequently for reducing psychological stress. As smartphones increasingly pervade our daily lives, people are ever more interrupted by alerts and notifications. Using both correlational and experimental methods, we explored whether such interruptions might be causing inattention and hyperactivity-symptoms associated with Attention Deficit Hyperactivity Disorder (ADHD) even in people not clinically diagnosed with ADHD. We recruited a sample of 221 participants from the general population. For one week, participants were assigned to maximize phone interruptions by keeping notification alerts on and their phones within their reach sight. During another week, participants were assigned to minimize phone interruptions by keeping alerts off and their phones away. Participants reported higher levels of inattention and hyperactivity when alerts were on than when alerts were off. Higher levels of inattention in turn predicted lower productivity and psychological well-being. These findings highlight some of the costs of ubiquitous connectivity and suggest how people can reduce these costs simply by adjusting existing phone settings. We report on an empirical study where we cut off email usage for five workdays for 13 information workers in an organization. We employed both quantitative measures such as computer log data and ethnographic methods to compare a baseline condition (normal email usage) with our experimental manipulation (email cutoff). Our results show that without email, people multitasked less and had a longer task focus, as measured by a lower frequency of shifting between windows and a longer duration of time spent working in each computer window. Further, we directly measured stress using wearable heart rate monitors and found that stress, as measured by heart rate variability, was lower without email. Interview data were consistent with our quantitative measures, as participants reported being able to focus more on their tasks. We discuss the implications for managing email better in organizations. Technology not only brings benefits such as flexible working practices but can also have negative stressful consequences such as increasing email overload and the blurring of work-home boundaries. We report on an exploratory study that extends the current understanding of email usage by investigating how different professions at a university manage work and personal emails using different devices and how this impacts their work-home boundary management. Our findings lead us to identify two user groups: those with permeable boundaries (primarily academics) and those who have more rigid ones (primarily professional services employees) and that there are differences in when, where and how they manage their work and personal emails. In particular we find that some participants use micro-boundary strategies to manage transitions between work and personal life. Based on these novel findings we propose improvements of email software design to facilitate effective email, work-home boundary management, and support micro-boundary practices. Smartphones are considered to be "always on, always connected" but mobile users are not always attentive and responsive to incoming communication. We present a mixed methods study investigating how mobile users use ringer modes for managing interruption by and awareness of incoming communication, and how these practices and locales affect their attentiveness and responsiveness. We show that mobile users have diverse ringer mode usage, but they switch ringer modes mainly for three purposes: avoiding interruption, preventing the phone from disrupting the environment, and noticing important notifications. In addition, without signals of notifications, users are less likely to immediately attend to notifications, but they are not less responsive to those they have attended. Finally, ringer mode switches, attentiveness, and responsiveness are all correlated with certain locales. We discuss implications from these findings, and suggest how future CMC tools and notification services take different purposes for using ringer modes and locales into consideration. Almost every office worker can relate to feelings of email overload and stress, but in reality the concept of email strain is not well understood. In this paper, we describe a large-scale nationwide organizational survey examining the relationship between email use and feelings of email overload and task coordination. We found that higher email volume was associated with increased feelings of email overload, but this relationship was moderated by certain email management strategies. The contribution to the field of CSCW is a better understanding of the concept of email related stress, and initial scale development for the assessment of email-related overload and perceptions of the work-importance of email.
