Cartoon ergonomics for working at the computer and laptopPosted: September 30, 2014 Filed under: Uncategorized | Tags: cell phones, computer, health, Laptop, muscle tension, neck pain, pain, posture, shoulder pain 6 Comments
I finally bought a separate keyboard and a small stand for my laptop so that the screen is at eye level and my shoulders are relaxed while typing at the keyboard. To my surprise, my neck and shoulder tightness and pain disappeared and I am much less exhausted.
How we sit and work at the computer significantly affects our health and productivity. Ergonomics is the science that offers guidelines on how to adjust your workspace and equipment to suit your individual needs. It is just like choosing appropriate shoes–Ever try jogging in high heels? The same process applies to the furniture and equipment you use when computing.
When people arrange their work setting according to good ergonomic principles and incorporate a healthy computing work style numerous disorders (e.g., fatigue, vision discomfort, head, neck, back, shoulder, arm or hand pain) may be prevented (Peper et al, 2004).

A breath of fresh air-Improve health with breathingPosted: September 11, 2014 Filed under: Breathing/respiration, Pain/discomfort, stress management, Uncategorized | Tags: asthma, Breathing, pain, regeneration, relaxation, respiration, stress management, yoga 10 Comments
“My breathing was something that took me a long time to adjust. I had been breathing almost entirely from my chest and my stomach was hardly moving when I breathed. I made a conscious effort all throughout the day to breathe slowly and with my stomach relaxed. I’ve noticed that my mood is much better when I am breathing this way, and I am much more relaxed. Immediately before I feel like I would have a seizure, if I would change my breathing technique and make sure I was breathing slowly and with my stomach. It would avoid the seizure from developing… This is a huge improvement for me.” –24 year old student who previously experienced 10 epileptic seizures per week
“I blanked out and could not remember the test material. I then reminded myself to breathe lower and slower while imagining the air slowly flowing down my legs. After three breaths, I could again process the information and continue to take the exam. A week later I got my grade back– an A-. Better than I had expected.” –21 year old student
Breathing occurs without awareness unless there are specific problems such as asthma, emphysema or when we run out of air while exercising. Breathing is more than just the air moving in and out. It is the boundary between the conscious and the unconscious—the voluntary and involuntary nervous system— and affects the sympathetic and parasympathetic activity of our body. The way we breathe, such as chronic low level hyperventilation, may contribute to increasing or decreasing anxiety, pain, epileptic seizure, exhaustion, abdominal pain, urinary incontinence or fertility.
We usually think of breathing occurring in our chest. Thus, during inhalation, we puff-up our chest so the lungs will expand. Observe that many people breathe this way and call it normal. Experience how you breathe:
Put your right and on your stomach and your left hand of your chest. Now take a quick big breath. Observe what happened. In most cases, your chest went up and your abdomen tightened and even pulled in.
This breathing pattern evokes a state of arousal and vigilance and activates your sympathetic nervous system. You tend to automatically tighten or pull in your stomach wall to protect your body. When we’re in pain, afraid, anticipate danger or have negative and fearful thoughts, “Do I have enough money for the rent,” or “Feeling rushed and waiting for a delayed Muni bus,” we instinctively hold our breath, slightly tense our muscles and breathe shallowly. Unfortunately, this makes the situation worse—symptoms such as pain, anxiety or abdominal discomfort will increase. This type of breathing is the part of the freeze response—a primal survival reflex. It may even affect our ability to think. Experience how dysfunctional breathing effects us by doing the following exercise (Peper & MacHose, 1993; Gorter & Peper, 2011).
Sit comfortably and breathe normally.
Now inhale normally, but exhale only 70 percent of the air you just inhaled.
Inhale again, and again only exhale 70 percent of the previously inhaled volume of air. If you need to sigh, just do it, and then return to this breathing pattern again by exhaling only 70 percent of the inhaled volume of air.
Continue to breathe in this pattern of 70 percent exhalation for about forty-five seconds, each time exhaling only 70 percent of the air you breathe in. Then stop, and observe what happened.
What did you notice? Within forty-five seconds, more than 98 percent of people report uncomfortable sensations such as lightheadedness, dizziness, anxiety or panic, tension in their neck, back, shoulders, or face, nervousness, an increased heart rate or palpitations, agitation or jitteriness, feeling flushed, tingling, breathlessness, chest pressure, gasping for air, or even a sensation of starving for air. This exercise may also aggravate symptoms that already exist, such as headaches, joint pain, or pain from an injury. If you’re feeling exhausted or stressed, the effects seem even worse.
On the other hand, if you breathed like a happy baby, or more like a peaceful dog lying on its side, the breathing movement occured mainly in the abdomen and the chest stays relaxed. This effortless diaphragmatic breathing promotes regeneration by allowing the abdomen to expand during inhalation and becoming smaller during exhalation as shown in Figure 1.
Figure 1. Illustration of diaphragmatic breathing in which the abdomen expands during inhalation and contracts during exhalation (reproduced by permission from Gorter, R. & Peper, E. (2011). Fighting Cancer-A Non Toxic Approach to Treatment. Berkeley: North Atlantic).
The abdominal movement created by the breathing improves blood and lymph circulation in the abdomen and normalizes gastrointestinal function and enhances regeneration. It supports sympathetic and parasympathetic balance especially when the breathing rate slows to about six breaths per minute. When breathing slower, exhaling takes about twice as long as the inhalation. When you inhale, the abdomen and lower ribs expand to allow the air to flow in and during exhalation the abdomen decreases in diameter and the breath slowly trails off. It is as if there is an upside down umbrella above the pelvic floor opening during inhalation and closing during exhalation.
Most people do not breathe this way . They suffer from “designer’s jean syndrome”. The clothing is too constricting to allow the abdomen to expand during inhalation (Remember how good it felt when you loosened your belt when eating a big meal?). Or, you are self-conscious of your stomach, “What would people thinks if my stomach hung out?” Yet, to regenerate, allow yourself to breathe like peaceful baby with the breathing movements occurring in the belly. Effortless diaphragmatic breathing is the cheapest way to improve your health. Thus observe yourself and transform your breathing patterns.
Interrupt breath holding and continue to breathe to enhance health. Observe situations where you hold your breath and then continue to breathe. If you expect pain during movement or a procedure, remember to allow your abdomen to expand during inhalation and then begin to exhaling whispering “Shhhhhhhhh.” Start exhaling and then begin your movement while continuing to exhale. In almost all cases the movement is less painful and easier. We observed this identical breathing pattern in our studies of Mr. Kawakami, a yogi who insert unsterilized skewers through his neck and tongue while exhaling—he did not experience any pain or bleeding as shown in Fig 2.
Figure 2. Demonstration by Mr. Kawakami, a yogi, who inserted non-sterile skewers while exhaling and reported no pain. When he removed the skewers there was no bleeding and the tissue healed rapidly (by permission from Peper, E., Kawakami, M., Sata, M. & Wilson, V.S. (2005). The physiological correlates of body piercing by a yoga master: Control of pain and bleeding. Subtle Energies & Energy Medicine Journal. 14(3), 223-237).
Shift shallow chest breathing to slower diaphragmatic breathing. Each time you catch yourself breathing higher in your chest. Stop. Focus on allowing your abdomen to expand during inhalation and become smaller during exhalation as if it was a balloon. Allow the air to flow smoothly during exhalation and allow the exhalation to be twice as long as the inhalation. Over time allow yourself to inhale to the count of three and exhale to the count of 6 or 7 without effort. Imagine that when you exhale the air flows down and through your legs and out your feet. As you continue to breathe this way, your heart rate will slightly increase during inhalation and decrease during exhalation which is an indication of sympathetic and parasympathetic restorative balance. A state that supports regeneration (for more information see, Peper, E. & Vicci Tibbetts, Effortless diaphragmatic breathing).
For many people when they practice these simple breathing skills during the day their blood pressure, anxiety and even pain decreases. While for other, it allows clarity of thought.
