Cell phones and tablets: Health risk and what to doPosted: January 16, 2015 Filed under: Uncategorized | Tags: cancer, cell phones, microwaves, radiation, wireless 1 Comment
Cellphones and laptops are part of our world; however, they are also a health risks as described in the previous blogs: Wireless devices may cause harm and Screens will hurt your children. For a superb summary of current research data see Louise Kuo Habakus’s post, An open letter to Apple Inc. It points out the dangers of tablets and smart phones’ radiation.
A poetic summary of risks and what can be done, read Lawrence Klein’s poem, Cell Phone Harm,
Phone Harmful: Poem
Keep mobile phones, tablets or laptops away from your body,
Wireless Devices may cause harm, this research is not shoddy,
Cervical spine stress caused by your communication possession,
Your head forward position increases cervical compression
On top of that there is an increase risk of brain cancer
It is enough to make you pause, before you answer,
Keep your cell phone away from your body and place
it in your purse or outer coat pocket, not near your face!
And use your speaker phone or ear phones instead
of placing the phone directly against your head.
It is impossible to belief that that only a few years ago,
there were no cell phones. So now when you go
home, put the phone away so you can be with your family.
Cell phone use is ubiquitous, sometime you need to get free!

Cellphone harm: Cervical spine stress and increase risk of brain cancerPosted: November 20, 2014 Filed under: Uncategorized | Tags: cancer, cell phones, ergonomics, health, microwaves, neck pain, posture, shoulder pain, wireless 2 Comments
It is impossible to belief that that only a few years ago there were no cell phones.
When I go home, I purposely put the phone away so that I can be present with my children.
I just wonder if the cell phone’s electromagnetic radiation could do harm?
Cell phone use is ubiquitous since information is only a key press or voice command away. Students spend about many hours a day looking and texting on a cell phone and experience exhaustion and neck and shoulder discomfort (Peper et al, 2013). Constant use may also have unexpected consequences: Increased stress on the cervical spine and increased risk for brain cancer.
Increased cervical spine stress
As we look at the screen, text messages or touch the screen for more information, we almost always bend our head down to look down. This head forward position increases cervical compression and stress. The more the head bends down to look, the more the stress in the neck increases as the muscles have to work much harder that hold the head up. In a superb analysis Dr. Kennth Hansraj, Chief of Spine Surgery 0f New York Spine Surgery & Rehabilitation Medicine, showed that stress on the cervical spine increases from 10-12 lbs when the head is in its upright position to 60 lbs when looking down.
Figure 1. Stress on the cervical spine as related to posture. (From: Hansraj, K. K. (2014). Assessment of stresses in the cervical spine caused by posture and position of the head. Surgical technology international, 25, 277-279.)
Looking down for a short time period is no problem; however, many of us look down for extended periods. This slouched collapsed position is becoming the more dominant position. A body posture which tends to decrease energy, and increase hopeless, helpless, powerless thoughts (Wilson & Peper, 2004; Peper & Lin, 2012). The long term effects of this habitual collapsed position are not know–one can expect more neck and back problems and increase in lower energy levels.
increased risk for brain cancer and inactive sperm and lower sperm count
Cell phone use not only affect posture, the cell phone radio-frequency electromagnetic radiation by which the cell phone communicates to the tower may negatively affect biological tissue. It would not be surprising that electromagnetic radiation could be harmful; since, it is identical to the frequencies used in your microwave ovens to cook food. The recent research by Drs Michael Carlberg and Lennart Hardell of the Department of Oncology, University Hospital, Örebro, Sweden, found that long term cell phone use is associated by an increased risk of developing malignant glioma (brain cancers) with the largest risk observed in people who used the cell phone before the age of 20. In addition, men who habitually carry the cell phone in a holster or in their pocket were more likely to have inactive or less mobile sperm as well as a lower sperm count.
What can you do:
Keep an upright posture and when using a cell phone or tablet. Every few minutes stretch, look up and reach upward with your hands to the sky.
Keep your cell phone away from your body such as putting it in your purse or outer pocket of your coat
Use your speaker phone or ear phones instead of placing the phone against your head.

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). For pragmatic tips to stay health at the computer see Erik Peper’s Health Computer Email Tips. Enjoy the following superb video cartoons uploaded by Stephen Walker on YouTube that summarize the basic guidelines for computer, laptop and cell phones use at work, home, or while traveling.
Adult or Child Laptop Use at Home, Work or Classroom

Technohealth reminderPosted: July 26, 2014 Filed under: Uncategorized | Tags: cell phones, digital devices, insomnia, microwaves, muscle tension, wireless Leave a comment
Digital devices connect us to each other, provide information from the outside world, allow us to work anywhere as long as there is Wi-Fi, and foster a 24/7 live style. It is almost impossible to remember driving without a smartphone that guides us to where we are going, or using it to find a restaurant or a place to stay. Being captured by the screen and the useful information, we may not be aware of the possible deleterious effects. Depending how the devices are used, they may contribute to disturbed sleep, increased attention deficit disorder in children, increased pedestrian death rates when the person is captured by the screen and not attending to the environment surrounding them, and increased cancer risks through antenna radiation. Some of the dangers have been integrated in a new poster, Mobile Phones: Ringing up the Danger, reprinted below from the website, http://www.cheapnursedegrees.com/mobile-phones-danger/
At the bottom of this poster are my suggestions to optimize technohealth while working with digital devices.

Suggestions to improve technohealth
Reverse and interrupt Stress Immobilization Syndrome
- Interrupt your computer work every few minutes to wiggle and move
- Breathe diaphragmatically
- Get up and do large movements (stretch or walk) for a few minutes.
- Take a short walk or do other movements instead of snacking when feeling tense or tired.
- Smile and realize that work stress it is not worth dying over
- Install a computer reminder program to signal you to take a short stress break such as StressBreak™.
- Eat lunch away from your computer workstation.
- Stand or walk during meetings or when talking on the phone.
- Turn off LED, TV or computer screens an hour before bedtime to promote restful sleep.
Reduce the possible harm from digital device’s antenna radiation
- Keep your phone, tablet or laptop in your purse, backpack or attaché case. Do not keep it on or close to your body.
- Use the speaker phone or plug in earphones with microphone while talking. Do not hold it against the side of your head, close to your breast or on your lap.
- Text while the phone or tablet is on a book or on a table away from your body.
Look up! Be aware and be open new possibilitiesPosted: May 4, 2014 Filed under: Uncategorized | Tags: anxiety, cell phones, health, loneliness 2 Comments
How is it possible that one is lonely while being connected to hundreds of Facebook friends, networked with even more LinkiedIn colleagues, and continuously sending and receiving Tweets and texts? Are we so captured by the digital devices that we do not notice the actual reality around us? Watch Gary Turk’s remarkable video and then remember to look up and connect with others.
Screens will hurt your childrenPosted: March 11, 2014 Filed under: Uncategorized | Tags: ADHD, attention, cell phones, exercise, smart phones, tablets 2 Comments
We park children in front of tablets, smartphone, computers and TVs. The visual and auditory stimulation captures their attention. It is a superb baby sitter. We substitute electronic displays for human attention.
To distract the baby at dinner in a restaurant, we hand the baby a smartphone. To have some private time, we let the child play games on the tablet. To reduce stress before dinner, we hand the child the tablet to watch video clips or play games. The short term benefits of letting handheld devices capture the child’s attention may have long term costs.
The child sits, sits and sits while being captured by the rapid changing visual scenes and auditory sounds instead of playing and enhancing motor development. The addictiveness of electronic devices occurs because we automatically attend to and are captured by rapidly changing stimuli—it is new and could be dangerous. This reaction to attend which is continuously evoked by the handheld devices may occur at the expense of developing self-directed attention.
The handheld devices expose the brain and dividing cells to electromagnetic radiation which can harmful. This is the radiation by which hand held devices communicates with connect cell phone towers or the server as it connects to the web.
From the precautionary principle and the numerous research studies, young children should limit the use of hand held devices. I totally agree with Cris Rowan’s superb blog, 10 Reasons Why Handheld Devices Should Be Banned for Children Under the Age of 12, which is reprinted below with her permission.
10 Reasons Why Handheld Devices Should Be Banned for Children Under the Age of 12
Cris Rowan pediatric occupational therapist, biologist, speaker, author
The American Academy of Pediatrics and the Canadian Society of Pediatrics state infants aged 0-2 years should not have any exposure to technology, 3-5 years be restricted to one hour per day, and 6-18 years restricted to 2 hours per day (AAP 2001/13, CPS 2010). Children and youth use 4-5 times the recommended amount of technology, with serious and often life threatening consequences (Kaiser Foundation 2010, Active Healthy Kids Canada 2012). Handheld devices (cell phones, tablets, electronic games) have dramatically increased the accessibility and usage of technology, especially by very young children (Common Sense Media, 2013). As a pediatric occupational therapist, I’m calling on parents, teachers and governments to ban the use of all handheld devices for children under the age of 12 years. Following are 10 research-based reasons for this ban. Please visit zonein.ca to view the Zone’s Fact Sheet for referenced research.
1. Rapid brain growth
Between 0 and 2 years, infant’s brains triple in size and continue in a state of rapid development to 21 years of age (Christakis 2011). Early brain development is determined by environmental stimuli or lack thereof. Stimulation to a developing brain caused by overexposure to technologies (cell phones, internet, iPads, TV), has been shown to be associated with executive functioning and attention deficit, cognitive delays, impaired learning, increased impulsivity and decreased ability to self-regulate e.g. tantrums (Small 2008, Pagini 2010).
2. Delayed Development
Technology use restricts movement, which can result in delayed development. One in three children now enter school developmentally delayed, negatively impacting literacy and academic achievement (HELP EDI Maps 2013). Movement enhances attention and learning ability (Ratey 2008). Use of technology under the age of 12 years is detrimental to child development and learning (Rowan 2010).
3. Epidemic Obesity
TV and video game use correlates with increased obesity (Tremblay 2005). Children who are allowed a device in their bedrooms have 30% increased incidence of obesity (Feng 2011). One in four Canadian, and one in three U.S. children are obese (Tremblay 2011). 30% of children with obesity will develop diabetes, and obese individuals are at higher risk for early stroke and heart attack, gravely shortening life expectancy (Center for Disease Control and Prevention 2010). Largely due to obesity, 21st century children may be the first generation many of whom will not outlive their parents (Professor Andrew Prentice, BBC News 2002).
4. Sleep Deprivation
60% of parents do not supervise their child’s technology usage, and 75% of children are allowed technology in their bedrooms (Kaiser Foundation 2010). 75% of children aged 9 and 10 years are sleep deprived to the extent that their grades are detrimentally impacted (Boston College 2012).
5. Mental Illness
Technology overuse is implicated as a causal factor in rising rates of child depression, anxiety, attachment disorder, attention deficit, autism, bipolar disorder, psychosis and problematic child behavior (Bristol University 2010, Mentzoni 2011, Shin 2011, Liberatore 2011, Robinson 2008). One in six Canadian children have a diagnosed mental illness, many of whom are on dangerous psychotropic medication (Waddell 2007).
Violent media content can cause child aggression (Anderson, 2007). Young children are increasingly exposed to rising incidence of physical and sexual violence in today’s media. “Grand Theft Auto V” portrays explicit sex, murder, rape, torture and mutilation, as do many movies and TV shows. The U.S. has categorized media violence as a Public Health Risk due to causal impact on child aggression (Huesmann 2007). Media reports increased use of restraints and seclusion rooms with children who exhibit uncontrolled aggression.
7. Digital dementia
High speed media content can contribute to attention deficit, as well as decreased concentration and memory, due to the brain pruning neuronal tracks to the frontal cortex (Christakis 2004, Small 2008). Children who can’t pay attention can’t learn.
As parents attach more and more to technology, they are detaching from their children. In the absence of parental attachment, detached children can attach to devices, which can result in addiction (Rowan 2010). One in 11 children aged 8-18 years are addicted to technology (Gentile 2009).
9. Radiation emission
In May of 2011, the World Health Organization classified cell phones (and other wireless devices) as a category 2B risk (possible carcinogen) due to radiation emission (WHO 2011). James McNamee with Health Canada in October of 2011 issued a cautionary warning stating “Children are more sensitive to a variety of agents than adults as their brains and immune systems are still developing, so you can’t say the risk would be equal for a small adult as for a child.” (Globe and Mail 2011). In December, 2013 Dr. Anthony Miller from the University of Toronto’s School of Public Health recommend that based on new research, radio frequency exposure should be reclassified as a 2A (probable carcinogen), not a 2B (possible carcinogen). American Academy of Pediatrics requested review of EMF radiation emissions from technology devices, citing three reasons regarding impact on children (AAP 2013).
The ways in which children are raised and educated with technology are no longer sustainable (Rowan 2010). Children are our future, but there is no future for children who overuse technology. A team-based approach is necessary and urgent in order to reduce the use of technology by children. Please reference below slide shows on www.zonein.ca under “videos” to share with others who are concerned about technology overuse by children.
Problems – Suffer the Children – 4 minutes
Solutions – Balanced Technology Management – 7 minutes
The following Technology Use Guidelines for children and youth were developed by Cris Rowan, pediatric occupational therapist and author of Virtual Child; Dr. Andrew Doan, neuroscientist and author of Hooked on Games; and Dr. Hilarie Cash, Director of reSTART Internet Addiction Recovery Program and author of Video Games and Your Kids, with contribution from the American Academy of Pediatrics and the Canadian Pediatric Society in an effort to ensure sustainable futures for all children.

Keep mobile phones, tablets or laptops away from your body: Wireless devices may cause harmPosted: April 27, 2013 Filed under: Uncategorized | Tags: brain cancer, cancer, cell phones, microwaves, wireless 56 Comments
Did you ever notice the heat of your mobile phone against your ear?
Did you ever feel the warmth of the laptop against your stomach and thighs?
While recording muscle tension, we sometimes observe a signal that is NOT the actual muscle contracting. It is an electrical signal that is recorded with sensors at the location of the body but not produced by the muscles. In some cases, this artifact is caused by the client’s mobile phone or other wireless device being activated even though the ringer function was set to off. Below is an example of an artifact signal that can be hundreds of times larger than the biological muscle (electromyography) or brainwave (electroencephalography) signal as shown in Figure 1.
Figure 1. Surface electromyography recording showing the effect of cell phone located 1 cm (0.4 inches) away from the electrodes (from: Lin, I.M. & Peper, E.,2009).
The artifact was caused by the microwaves radiating from the cell phone antenna as it communicated to the by cell phone tower. As long as the cell phone and the wireless devices are being used for talking, texting, streaming data, or audio and visual media, they are communicating with the tower. Most cell phones, as long as they can receive calls, also connect every 900 milliseconds to the tower to report its location. To prevent artifacts in electromyographic and electroencephalographic recording, request clients to turn off their mobile phone or switch it to airplane mode.
When we initially observed this artifact produced by the mobile phone antenna signal, we wondered if this could be a health risk. I was further persuaded after reading epidemiologist, Devra Davis, Ph.D superb book, Disconnect- The Truth about cell phone radiation, What the industry is doing to hide it, and How to protect your family. For more information see her website Environmental Health Trust (http://ehtrust.org/).
Although being exposed by microwave radiation at 1 watt of power output while talking is not the same as being blasted for two minutes by 1000 watts necessary to bring a cup of water to boil in a microwave, most of us experience ongoing exposure for many minutes per day. We are now connected 24/7- anywhere we go-from coffee shop to the bedroom. We tend to keep cell phones and other wireless devices on our person. Men often stash it in their pant pockets and woman sometimes in their bra. Yes, you can even buy a bra with a built in cell phone pocket.
We use smartphones and tablets as a communication device for texting, talking, updating our social networks, searching the web, and as an alarm clock next to our head while sleeping (we do not want to disturb our roommate or partner). Smart phones and tablets have become omnipresent in our world. They are used in classes, while waiting for appointments (the stack of dated magazines have become irrelevant), and are the last thing we check before going to sleep. Soon these devices will be so small that they will be inserted in our ear, under our skin, or embedded in our glasses — truly connected at all times.
In our 2012 survey, university students used mobile phones and tablets/i-Pads for at least 118 minutes a day, of which 40 minutes occurred just before going to sleep. This meant that they spent 19.7 days a year texting/talking on their smartphones (Waderick et al, 2013) as shown in figure 2.
Figure 2. Minutes of smart phone and tablet used by students and the percentage of disturbed sleep and hours of sleep (from: Waderich, K., Peper, E., Harvey, R., & Sutter, S., 2013).
In less than 20 years, we can no longer imagine a life without these wireless devices and go into a panic when they are missing. We have accepted the new technology and assumed that it is safe. Yet, could this be similar to the early cigarette debates in the tobacco industry? Most of the published studies claimed that cigarettes did not harm people and had nothing to do with cancer. We now know better. One cigarette probably does no harm; however, smoking many cigarettes over numerous years does cause harm.
When radar was initially developed in World War II, some sailors on ships in the North Atlantic Ocean warmed themselves by momentarily standing in front of the radar beam. While they did get warmer, they also became sterile for a period of time since heating the testicles with radar reduced sperm production. Could a similar effect occur by the heat and microwaves emitted from a laptop, tablet, or cell phone against the abdomen or lap?
Research findings over the last twenty years have often been ambiguous, although indicating that there is a risk (Davis, 2010). It is unlikely that the telecommunication industry will support research into possible dangers since it would put them at financial risk. Instead, the telecommunication industry lobbies to oppose laws that would require right to know labeling of cell phones with disclosure of possible risks or antenna output power. A more neutral perspective is reported by the International Agency for Research into Cancer (IARC), which is part of the World Health Organization World Health Organization (WHO). As of 2011, the WHO has classified mobile phones (and any wireless device that uses microwaves to communicate) as a group2b risk, which means that they are “possibly carcinogenic to humans” and there is “limited evidence” that something causes cancer in people, and even the evidence from animal studies is “less than sufficient”.
Research studies report that adults who have used mobile phones intensively for at least ten years experience an increase in brain cancer (glioma and acoustic neuroma), salivary gland cancer, and even rare eye cancers on the side of the head where the cell phone was predominantly held (Davis, 2010). Some men diagnosed with testicular cancer had the cancer occur in the testicle that was closest to the pant pocket where they stashed their cell phone (Davis, 2013).
More recently, some women who have habitually stashed their cell phone in their bra have been diagnosed with a rare breast cancer located beneath the area of the breast where they stored their cell phone. Watch the heart breaking TV interview with Tiffany. She was 21 years old when she developed breast cancer which was located right beneath the breast were she had kept her cell phone against her bare skin for the last 6 years.
While these rare cases could have occurred by chance, they could also be an early indicator of risk. Most research studies were based upon older adults who have tended to use their mobile phone much less than most young people today. The average age a person acquires a mobile phone is ten years old. Now infants and toddlers are entertained by smartphones and tablets–the new technological babysitter. The possible risk may be much greater for a young people since their bodies and brains are still growing rapidly. I wonder if the antenna radiation may be one of the many initiators or promoters of later onset cancers. And, most cancer take twenty or more years to develop.
Instead of waiting for twenty or thirty years to find out definitively whether the antenna radiation is, or is not, harmful, adapt the precautionary principle and reduce your and your children’s exposure. The simplest strategy is to keep the devices away from your body. The further it is away the device is from the body the less power of the antenna signal reaches you as shown in figure 3.
Figure 3. Decrease in amplitude of microwave emission as recorded from the skin as a function of distance (from: Lin, I.M. & Peper, E., 2009).
Why take the risk! Act now and reduce the exposure to the antenna radiation by implementing the following suggestions:
- Keep your phone, tablet or laptop in your purse, backpack or attaché case. Do not keep it on or close to your body.
- Use the speaker phone or plug in earphones with microphone while talking. Do not hold it against the side of your head, close to your breast or on your lap.
- Text while the phone is on a book or on a table away from your body.
- Put the tablet and laptop on a table and away from the genitals.
- Be old fashioned and use a cable to connect to your home router instead of relying on the WiFi connection.
- Keep your calls short and enjoy the people in person.
- Support legislation to label wireless devices with a legible statement of possible risk and the specific absorption rate (SAR) value. Generally, higher the SAR value, the higher the exposure to antenna radiation.
- Support the work by the Environmental Health Trust.
