No Link Between Cell Phone Use and Brain Cancer

Largest study ever of cell phone use finds no additional risk for brain cancer.

The way Denmark tracks information about its citizens has made it a unique laboratory for long-term population studies. Taking advantage of this, researchers have found that after adjusting for things like age, years of cellphone use, and income there was no observed link between phone users and cancer. After 15 years of exposure, no dose effect was seen either. 

PositiveTip: While these findings are comforting, it is still probably prudent to avoid constant talking on your cellphone unless using some type of earphone.


Limit Kids Media for Their Good

The report from the Kaiser Family Foundation on media and sleep concludes their review with this statement:

William Dement, a professor at Stanford University and a leading sleep researcher has written, “…my most significant finding is that ignorance is the worst sleep disorder of all.” This review of the literature on sleep and media use among children indicates that while there are some things we do know about media and sleep, there is much more about which we are still ignorant.

It is extremely important to understand that all of the different types of media to which our kids are exposed can cause both measurable effects and other effects that we don’t yet understand.

The Media and Sleep

Scared mature womanThe report from the Kaiser Family Foundation goes on to discuss possible nightmares and new forms of media.

Media use and nightmares: Research has shown that many children may experience nightmares resulting from something they viewed on TV or in an electronic game, and most children have young children who view to this kind of media do not find it relaxing.

On the other hand, there are also new television programs that have been specifically created to calm children down and help them fall asleep, and are promoted to parents as such.

Cell Phone Use and Alzheimer's Disease

Cell phone use might actually help prevent Alzheimer's disease! Really?

The Journal of Alzheimer's Disease has reported that researchers exposed normal mice and mice genetically bred to develop Alzheimer's disease (AD) to electromagnetic fields (EMF) at frequencies equivalent to cell phones for 2 hours each day. After 7-9 months those mice exposed to the EMF were actually protected against cognitive impairment, and  AD-like symptoms were reversed in the mice predisposed to AD. Improved cognitive performance was measured in the normal mice, too.
