When I sit with good posture on my computer, I am significantly more engaged in what I’m doing. When I slouch on my computer I tend to procrastinate, go on my phone, and get distracted so it ends up taking much longer to do my work when my posture is bad.…I have ADHD and I struggle a lot with my mind wandering when I should be paying attention. Having good posture really helps me to lock in and focus.—22 year old male student.
Over the past two decades, there has been a significant increase in the prevalence of attention-deficit/hyperactivity disorder (ADHD), anxiety, and depression. ADHD rates have increased from 6% in 1997 to approximately 10% in 2018 (CDC, 2022). The rates of anxiety among 18–25 year-olds have also increased from 7.97% in 2008 to 14.66% in 2018 (Goodwin et al., 2020). Students are more distracted, stressed and exhausted (Hanscom, 2022; Hoyt et al., 2021). The more students are distracted, the lower their academic achievement (Feng et al., 2019). In our recent class survey of more than 100 junior and senior college students on the first day of class, 54% reported that they were tired and dreading the day when they woke up. When you are tired and stressed it is difficult to focus attention and have clarity of thought. Their self-report is similar to the mental health trends in the United States by age group in 2008–2019. Mental health of young people has significantly deteriorated over the last 15 years (Braghieri et al., 2021/2023).
The increase in psychological distress is most prevalent in people ages 18–29 and who were brought up with the cellphone (the iPhone was introduced in 2007) and social media. Now when students enter a class, they tend to sit down, look down at their cellphone while slouching, and they do not make contact with most other students unless instructed or reminded by the instructor. When instructed to talk to another student for less than 5 minutes (e.g., share something positive that happened to you this week), 93% of the students reported an increase in subjective energy and alertness (Peper, 2024).
As a group, students are social media and cell phone natives and thus have many distractions and stimuli to which they continuously respond. It is not surprising that the average attention span has decreased from 150 seconds in 2004 to 44 seconds in 2021 (Mark, 2023). More importantly, they now tend to sit in a slouched collapsed position, which facilitates access to hopeless, helpless, powerless and defeated thoughts and memories (Tsai et al., 2016; Peper et al., 2017) and reduces cognitive performance when performing mental math (Peper et al., 2018). Sitting slouched and looking down also reduces peripheral awareness and increases shallow thoracic breathing—a breathing pattern that increases the risk of anxiety. Experience this yourself.
For a minute, look at your cellphone while intensely reading the text or searching social media in the following two positions: sitting straight up and looking straight ahead at your cell phone or slouching and looking down at your cell phone, as shown in Figure 1. Most likely, your experience is similar to the findings from the classroom observational study in which half the students looked down and the other half looked straight ahead and then reversed their positions (Peper, unpublished). They then compared the subjective experience associated with the position. In the slouched position, most experienced a reduction in peripheral awareness and breathed more shallowly (see Figure 1).

Figure 1. Effect of slouching or looking straight ahead on vision and breathing.
The slouched position reduces social awareness and decreases awareness of external stimuli as illustrated in Steve Cutts’ superb animation, Mobile world (https://www.youtube.com/watch?v=wUW1wjlKvmY).
Given the constant stimulation, distractions and shortened attention span, it is more challenging to be calm and have clarity of mind when having to study or take an exam at school. As educators, we constantly explore ways to engage students and support their learning and especially share quick skills they can use to optimize performance (Peper& Wilson, 2021). In previous research, Harvey et al., 2020 showed that students who used posture feedback improved their health scores compared to the control group. The purpose of this paper is to share a 4-week class assignment by which numerous students reported an increase in attention, concentration, confidence, school performance and a decrease in stress.
Participants: 18 undergraduate students (7 males and 11 females, average age 22 [STDEV 2.2]) enrolled in an upper division class. As a report about an effort to improve the quality of a classroom activity, this report of findings was exempted from Institutional Review Board oversight.
Equipment: Wearable posture feedback device, UpRight Go 2, which the person wears on their neck and which provides vibratory feedback whenever they slouch, as shown in Figure 2. It is used in conjunction with the cellphone app that allows them to calibrate the feedback device.

Figure 2. Attachment of posture feedback device on neck or spine and the app to calibrate the device.
Procedure: Students attended the 3-hour weekly class that explored autogenic training, somatic awareness, psychobiology of stress, the role of posture, and the psychophysiology of respiration. The lectures included short experiential practices demonstrating the body-mind connections such as imagining a lemon to increase salivation, the effect of slouched versus erect posture on evoking positive/empowering or hopeless/helpless/powerless/defeated thoughts, and the effect of sequential 70% exhalation for 30 seconds on increasing anxiety (Tsai et al., 2016; Peper et al., 2017).
Each week for 4 weeks the students were assigned a self-practice that they would implement daily at home and record their experiences. At the end of the week, they reviewed their own log and summarized their own observations (benefits, difficulties). During the next class session, they met in small groups of 5 to 6 students to discuss their experiences and extract common themes.
The 4-week curriculum was sequenced as follows:
Week 1
- Lecture on the benefits/harms of posture with experiential practices (effect of slouching vs erect on access to hopeless/helpless/powerless thoughts versus optimistic and empowering thoughts; posture and arm strength (Peper, 2022).
- Homework assignments:
- Watch the great Ted Talk and one of the most viewed by Amy Cuddy (2013), “Your body language shapes who you are.”
- Keep a detailed log to monitor situations where they slouched and identify situations that were associated with slouching.
Week 2
- Lecture on psychophysiology and class discussion in which students shared their experiences of slouching; namely, what were the triggers, how it affected them and what they could do to change.
- Demonstration, explanation, and how to use the posture feedback device, UpRight Go 2.
- Homework assignment: Wear UpRight Go 2 during the day, use it in different settings (studying, walking, work), and keep a log. When it vibrates (slouching) observe what was going on and change your behavior such as when tired>get rest or do exercise; when depressed>change internal language; ergonomic issues>change the environment, posture>give yourself lower back support.
Week 3
- Class discussion on what to do when slouching is triggered by tiredness, negative and hopeless thoughts, ergonomics such as laptop placement and chair. Students meet in groups to share their experiences and what they did in response to the vibratory feedback.
- Homework assignment: Continue to wear the UpRight Go 2 during the day and keep a log.
Week 4
- Class discussion in groups of five students about their experiences of slouching, what to do and how it affects them.
- Homework assignment: Wear UpRight Go 2 during the day and keep a log. Submit a paper that describes their experience with the posture feedback from the UpRight Go 2 and fill out a short anonymous survey in which they rated their change in experience since using the posture feedback device on a scale from 3 (worse) to 0 (no change) to 3 (better) .
Results
All students reported that wearing the feedback device increased attention and concentration as shown in Figure 3.

Figure 3.
Amount of time using the UpRight Go 2:On the average the students used the device 4.8 days a week (STDEV 2.0) and 2.2 hours per day (STDEV 1.3).
Location of use:Although most students practiced sitting in front of their computer, they also reported using it while at work, playing pool or doing yoga and even while seeing a therapist.
Discussion
All the students reported that the posture feedback helped them to become more aware of slouching and when they then interrupted their slouching, they experienced an increase in energy and a decrease in stress. As a 21-year-old male student said: “I felt more engaged with whatever I was doing. I tend to … daydream and get distracted, but I experience much less of that when I sit with good posture.”
Many reported that it helped identify their emotions when they were feeling overwhelmed. Then they could sit up, shift their perspective, and many reported a decrease in back and neck pain as well as a decrease in tiredness. When participants wear non-invasive wearables that provide accurate feedback, they are often surprised what triggers are associated with feedback or how their performance improves when they respond to the feedback signal by changing their thoughts and behavior. This posture self-awareness project should be embedded in strategies that optimize the learning state as described by Peper & Wilson (2021).
To the students’ surprise, they were often unaware that they started to slouch, nor were they aware of how much this slouching was connected to their emotions, mental state or external factors. For example, one student reported that he wore the device while being in a therapy session. All of a sudden, it vibrated. At that moment, he realized that he was becoming anxious, although he and therapist were unaware. He then shared what happened with the therapist, and that helped the therapeutic process.
The benefits may not only be due to posture change but that the students became aware and interrupted their habitual pattern. This process is similar to that described by Charles Stroebel (1985) when he taught patients the Quieting Reflect that reduced numerous somatic symptoms ranging from headaches to hypertension.
The posture feedback intervention is both simple and challenging since it requires the participants to wear the device, identify factors that trigger the slouching, and interrupt their automatic patterns by changing posture and behavior whenever they felt the vibratory feedback. The awareness gave them the opportunity to change posture and thoughts. By shifting to an upright posture, they experienced that they could concentrate more and have increased energy. As a 19-year-old female student wrote: “My breathing was better and sitting in an upright position gave me more energy when doing tasks.”
Conclusion
We recommend that a 4-week home practice module that incorporates wearable posture feedback is offered to all students to enhance their well-being. With the posture feedback, participants can increase their awareness of slouching, identify situations that trigger slouch, and learn strategies to shift their posture, thoughts, emotions and external environment to optimize maintaining an empowered position. As a 20-year old male student reported, “The app helped me when I was feeling overwhelmed and then I would sit up. When I had it on, I did a lot of work. I was more concentrated.”

Reduce anxiety

The purpose of this blog is to describe how a university class that incorporated structured self-experience practices reduced self-reported anxiety symptoms (Peper, Harvey, Cuellar, & Membrila, 2022). This approach is different from a clinical treatment approach as it focused on empowerment and mastery learning (Peper, Miceli, & Harvey, 2016).
As a result of my practice, I felt my anxiety and my menstrual cramps decrease. — College senior
When I changed back to slower diaphragmatic breathin, I was more aware of my negative emotions and I was able to reduce the stress and anxiety I was feeling with the deep diaphragmatic breathing.– College junior
Background
More than half of college students now report anxiety (Coakley et al., 2021). In our recent survey during the first day of the spring semester class, 59% of the students reported feeling tired, dreading their day, being distracted, lacking mental clarity and had difficulty concentrating.
Before the COVID pandemic nearly one-third of students had or developed moderate or severe anxiety or depression while being at college (Adams et al., 2021. The pandemic accelerated a trend of increasing anxiety that was already occurring. “The prevalence of major depressive disorder among graduate and professional students is two times higher in 2020 compared to 2019 and the prevalence of generalized anxiety disorder is 1.5 times higher than in 2019” As reported by Chirikov et al (2020) from the UC Berkeley SERU Consortium Reports.
This increase in anxiety has both short and long term performance and health consequences. Severe anxiety reduces cognitive functioning and is a risk factor for early dementia (Bierman et al., 2005; Richmond-Rakerd et al, 2022). It also increases the risk for asthma, arthritis, back/neck problems, chronic headache, diabetes, heart disease, hypertension, pain, obesity and ulcer (Bhattacharya et al., 2014; Kang et al, 2017).
The most commonly used treatment for anxiety are pharmaceutical and cognitive behavior therapy (CBT) (Kaczkurkin & Foa, 2015). The anti-anxiety drugs are usually benzodiazepines (e.g., alprazolam (Xanax), clonazepam (Klonopin), chlordiazepoxide (Librium), diazepam (Valium) and lorazepam (Ativan). Although these drugs they may reduce anxiety, they have numerous side effects such as drowsiness, irritability, dizziness, memory and attention problems, and physical dependence (Shri, 2012; Crane, 2013).
Cognitive behavior therapy techniques based upon the assumption that anxiety is primarily a disorder in thinking which then causes the symptoms and behaviors associated with anxiety. Thus, the primary treatment intervention focuses on changing thoughts.
Given the significant increase in anxiety and the potential long term negative health risks, there is need to provide educational strategies to empower students to prevent and reduce their anxiety. A holistic approach is one that assumes that body and mind are one and that soma/body, emotions and thoughts interchangeably affect the development of anxiety. Initially in our research, Peper, Lin, Harvey & Perez (2017) reported that it was easier to access hopeless, helpless, powerless and defeated memories in a slouched position than an upright position and it was easier to access empowering positive memories in an upright position than a slouched position. Our research on transforming hopeless, helpless, depressive thought to empowering thoughts, Peper, Harvey & Hamiel (2019) found that it was much more effective if the person first shifts to an upright posture, then begins slow diaphragmatic breathing and finally reframes their negative to empowering/positive thoughts. Participants were able to reframe stressful memories much more easily when in an upright posture compared to a slouched posture and reported a significant reduction in negative thoughts, anxiety (they also reported a significant decrease in negative thoughts, anxiety and tension as compared to those attempting to just change their thoughts).
The strategies to reduce anxiety focus on breathing and posture change. At the same time there are many other factors that may contribute the onset or maintenance of anxiety such as social isolation, economic insecurity, etc. In addition, low glucose levels can increase irritability and may lower the threshold of experiencing anxiety or impulsive behavior (Barr, Peper, & Swatzyna, 2019; Brad et al, 2014). This is often labeled as being “hangry” (MacCormack & Lindquist, 2019). Thus, by changing a high glycemic diet to a low glycemic diet may reduce the somatic discomfort (which can be interpreted as anxiety) triggered by low glucose levels. In addition, people are also sitting more and more in front of screens. In this position, they tend to breathe quicker and more shallowly in their chest.
Shallow rapid breathing tends to reduce pCO2 and contributes to subclinical hyperventilation which could be experienced as anxiety (Lum, 1981; Wilhelm et al., 2001; Du Pasquier et al, 2020). Experimentally, the feeling of anxiety can rapidly be evoked by instructing a person to sequentially exhale about 70 % of the inhaled air continuously for 30 seconds. After 30 seconds, most participants reported a significant increase in anxiety (Peper & MacHose, 1993). Thus, the combination of sitting, shallow breathing and increased stress from the pandemic are all cofactors that may contribute to the self-reported increase in anxiety.
To reduce anxiety and discomfort, McGrady and Moss (2013) suggested that self-regulation and stress management approaches be offered as the initial treatment/teaching strategy in health care instead of medication. One of the useful approaches to reduce sympathetic arousal and optimize health is breathing awareness and retraining (Gilbert, 2003).
Stress management as part of a university holistic health class
Every semester since 1976, up to 180 undergraduates have enrolled in a three-unit Holistic Health class on stress management and self-healing (Klein & Peper, 2013). Students in the class are assigned self-healing projects using techniques that focus on awareness of stress, dynamic regeneration, stress reduction imagery for healing, and other behavioral change techniques adapted from the book, Make Health Happen (Peper, Gibney & Holt, 2002).
82% of students self-reported that they were ‘mostly successful’ in achieving their self-healing goals. Students have consistently reported achieving positive benefits such as increasing physical fitness, changing diets, reducing depression, anxiety, and pain, eliminating eczema, and even reducing substance abuse (Peper et al., 2003; Bier et al., 2005; Peper et al., 2014).
This assessment reports how students’ anxiety decreased after five weeks of daily practice. The students filled out an anonymous survey in which they rated the change in their discomfort after practicing effortless diaphragmatic breathing. More than 70% of the students reported a decrease in anxiety. In addition, they reported decreases in symptoms of stress, neck and shoulder pain as shown in Figure 1.

Figure 1. Self-report of decrease in symptoms after practice diaphragmatic breathing for a week.
In comparing the self-reported responses of the students in the holistic health class to those of the control group (N=12), the students in the holistic health class reported a significant decrease in symptoms since the beginning of the semester as compared to the control group as shown in Figure 2.

Figure 2. Change in self-reported symptoms after 6 weeks of practice the integrated holistic health skills as compared to the control group who did not practice these skills.
Changes in symptoms Most students also reported an increase in mental clarity and concentration that improved their study habits. As one student noted: Now that I breathe properly, I have less mental fog and feel less overwhelmed and more relaxed. My shoulders don’t feel tense, and my muscles are not as achy at the end of the day.
The teaching components for the first five weeks included a focus on the psychobiology of stress, the role of posture, and psychophysiology of respiration. The class included didactic presentations and daily self-practice
Lecture content
- Diadactic presentation on the physiology of stress and how posture impacts health.
- Self-observation of stress reactions; energy drain/energy gain and learning dynamic relaxation.
- Short experiential practices so that the student can experience how slouched posture allows easier access to helpless, hopeless, powerless and defeated memories.
- Short experiential breathing practices to show how breathing holding occurs and how 70% exhalation within 30 seconds increases anxiety.
- Didactic presentation on the physiology of breathing and how a constricted waist tends to have the person breathe high in their chest (the cause of neurasthemia) and how the fight/flight response triggers chest breathing, breath holding and/or shallow breathing.
- Explanation and practice of diaphragmatic breathing.
Daily self-practice
Students were assigned weekly daily self-practices which included both skill mastery by practicing for 20 minutes as well and implementing the skill during their daily life. They then recorded their experiences after the practice. At the end of the week, they reviewed their own log of week and summarized their observations (benefits, difficulties) and then met in small groups to discuss their experiences and extract common themes. These daily practices consisted of:
- Awareness of stress. Monitoring how they reacted to daily stressor
- Practicing dynamic relaxation. Students practiced for 20 minutes a modified progressive relaxation exercise and observed and inhibit bracing pattern
- Changing energy drain and energy gains. Students observed what events reduced or increased their subjective energy and implemented changes in their behavior to decrease events that reduced their energy and increased behaviors that increase their enery
- Creating a memory of wholeness practice
- Practicing effortless breathing. Students practiced slowly diaphragmatic abdominal breathing for 20 minutes per day and each time they become aware of dysfunctional breathing (breath holding, shallow chest breathing, gasping) during the day, they would shift to slower diaphragmatic breathing.
Discussion
Almost all students were surprised how beneficial these practices were to reduce their anxiety and symptoms. Generally, the more the students would interrupt their personal stress responses during the day by shifting to diaphragmatic breathing the more did they experience success. We hypothesize that some of the following factors contributed to the students’ improvement.
- Learning through self-mastery as an education approach versus clinical treatment.
- Generalizing the skills into daily life and activities. Practicing the skills during the day in which the cue of a stress reaction triggered the person to breathe slowly. The breathing would reduce the sympathetic activation.
- Interrupting escalating sympathetic arousal. Responding with an intervention reduced the sense of being overwhelmed and unable to cope by the participant by taking charge and performing an active task.
- Redirecting attention and thoughts away from the anxiety triggers to a positive task.
- Increasing heart rate variability. Through slow breathing heart rate variability increased which enhanced sympathetic parasympathetic balance.
- Reducing subclinical hyperventilation by breathing slower and thereby increasing pC02.
- Increasing social support by meeting in small groups. The class discussion group normalized the anxiety experiences.
- Providing hope. The class lectures, assigned readings and videos provide hope; since, it included reports how other students had reversed their chronic disorders such as irritable bowel disease, acid reflux, psoriasis with behavioral interventions.
Although the study lacked a control group and is only based upon self-report, it offers an economical non-pharmaceutical approach to reduce anxiety. These stress management strategies may not resolve anxiety for everyone. Nevertheless, we recommend that schools implement this approach as the first education intervention to improve health in which students are taught about stress management, learn and practice relaxation and diaphragmatic breathing and then practice these skills during the day whenever they experience stress or dysfunctional breathing.
I noticed that breathing helped tremendously with my anxiety. I was able to feel okay without having that dreadful feeling stay in my chest and I felt it escape in my exhales. I also felt that I was able to breathe deeper and relax better altogether. It was therapeutic, I felt more present, aware, and energized.
