Cellphone harm: Cervical spine stress and increase risk of brain cancer

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.

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.
