New research published in the Archives of Environmental and Occupational Health evaluated five commonly used laptops of different brands.
After measuring the EMF exposure produced, researchers found EMF values were within the guidelines put forth by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), but "considerably higher than the values recommended by 2 recent guidelines for computer monitors magnetic field emissions, MPR II (Swedish Board for Technical Accreditation) and TCO (Swedish Confederation of Professional Employees), and those considered risky for tumor development."
Further they noted that the EMF values became alarmingly high when the laptop was used close to the body:
"When close to the body, the laptop induces currents that are within 34.2% to 49.8% ICNIRP recommendations, but not negligible, to the adult's body and to the fetus (in pregnant women).
On the contrary, the power supply induces strong intracorporal electric current densities in the fetus and in the adult subject, which are respectively 182-263% and 71-483% higher than ICNIRP 98 basic restriction recommended to prevent adverse health effects."
This led them to conclude:
"Laptop is paradoxically an improper site for the use of a LTC, which consequently should be renamed to not induce customers towards an improper use."
Laptop computers represent a source of both electromagnetic energy exposure (Wi-Fi) as well as thermal energy (heat).
There is a small but growing body of literature showing potential adverse effects on human sperm. In a laboratory experiment (in vitro), human donor sperm samples were exposed to four hours of a laptop computer connected to Wi-Fi. A significant decrease in progressive motility and an increase in sperm DNA fragmentation (breaks in the chromosomes) were observed.
The heat generated by laptop computers while held in the lap can cause significant elevation (> 1º C) in scrotal temperature within 15 minutes.
What you should know:
- Men should limit carrying a cell phone in their pants pocket or wearing on a belt holder.
- Limit the use of laptop computers in the lap position especially for teenage boys, young men of the reproductive age and men attempting pregnancy.
- Avoid all forms of scrotal heat exposure.
Why Your Reproductive Health May be Especially at Risk
If you're a man who uses a laptop often, and you would like to have children in the future, or simply protect your reproductive health, consider this a warning … In the first study to evaluate the direct impact of laptop use on human sperm, published in the journal Fertility and Sterility, those exposed to a wireless internet-connected laptop showed a significant decrease in sperm motility and an increase in sperm DNA fragmentation. And this was after just four hours of exposure. Researchers concluded:
"We speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility."
The culprit? Once again, it appears the electromagnetic radiation generated during use of wireless devices, similar to that generated during cell phone use, may have a devastating impact on your fertility.
Previous studies have found that laptop use may damage sperm through a thermal effect, that is, by heating up the scrotum during use (this occurred even when a lap pad was used, most likely because the men’s closed leg position, required to balance the laptop, also contributed to the heating effect). However the current study found laptop use also leads to non-thermal adverse effects, which means even if you manage to avoid the heating effect, laptop use, on your lap, may still damage your fertility.
This is an area that deserves immediate and serious attention, considering use of wireless technologies is growing at an exponential rate. And it's not only laptops that are the problem … According to a study published in Fertility and Sterility in 2008,ii statistically significant changes were found in men’s sperm count and health of the sperm based on cell phone use, too. Their conclusion?
"Use of cell phones decreases the semen quality in men by decreasing the sperm count, motility, viability and normal morphology. The decrease in sperm parameters was dependent on the duration of daily exposure to cell phones, and independent of the initial semen quality."
Why it May be Better to Use a Battery-Powered Laptop
Laptop computers are a high-energy source of both electric- and magnetic fields, so, as mentioned, avoid putting a laptop directly on your lap. You can block the thermal effects by using a lap pad if you also avoid sitting with your legs held closely together, and you can shield against the electric field by adding a reflective material or metal to it, but you cannot block the magnetic field component …
What's worse is that computer-charging devices are ungrounded, so ideally you'll only want to use a laptop when it's running on battery -- not when it's plugged into an outlet and charging. The same goes for iPads, Kindle's and even cell phones. Pregnant women should be especially careful using these types of technologies while plugged in. According to Vickie Warren, former executive director of the Bau-Biologie Group for the United States, the amount of EMF you’re exposed to from laptop that is plugged in compared to a laptop that is running on battery is about 100 times higher!
The current Archives of Environmental and Occupational Health study also suggested that the power supply from a laptop induces strong electric current densities in the fetus when the laptop is used at close contact with a woman's womb, so taken together the research suggests that both men and women should use due care when considering whether or not to use a laptop, especially in close proximity to their bodies.
However, my measurements show that the EMF coming from the device is still unacceptable even when it is plugged in, so, as I mentioned above, I would strongly encourage you to only use your notebook computer with an external keyboard.

EMF Protection
Perhaps you’re dealing with some of the symptoms that people commonly experience with exposure to electromagnetic fields. But even if you’re not, you may not want to take chances with problems that may show up down the road. And if you have children, you may be especially concerned.
Since there’s no way to easily avoid electromagnetic radiation in today’s world, the only sane solution is getting EMF protection.MHT offers a product that have been tested and proven effective. Click on PRODUCT to learn more.
If you must be on your cell phone on a regular basis, cell phone protectors are a must - though I want to emphasize, the above information is critical to protect yourself from wireless radiation. For cell phones and brain cancer protection, quality and effectiveness should not be compromised.
Not Sure You Want to Make These Changes?
So you think these changes will crimp your lifestyle? Cell phones and brain cancer is a relatively new health problem to think about, but if you are waiting for the truth to be mainstream about cell phones cancer, if you get pain in your head on a daily basis, if you use your phone on a daily basis – your risk of brain cancer is escalating day by day. Once you get a brain cancer diagnosis, you will wish you had taken some precautions for protection.
Cell phones are the biggest direct threat to human health on the market today. They can also be one of the greatest benefits. You have a virtual encyclopedia at your fingertips. But at the same time, your brain is being attacked by a potential threat and can rob you of your ability to think at all. You and your loved ones deserve the benefits of your cell phones—but without the dangers.
Remember, NOTHING heals the body – the body heals itself when provided with what it needs! Wireless radiation is damaging to healthy brain cells. Protect your brain now!
