29. Carry your phone properly when you must carry it close to you. “If you must carry your cellphone on you, keep the keypad position toward your body and the back toward the outside to have the electromagnetic fields move away from you, rather than through you, according to Consumerist.” – Lizette Borreli, Teenage Girl Wakes to Samsung Galaxy S4 Catching Fire Under Pillow: 4 Ways to Make Your Cell Phone Safer, Medical Daily; Twitter: @lizcelineb

That may be true today. But some experts have grave concerns about the types of low-intensity radiation our wireless devices produce. “We have animal studies suggesting even low-level exposures to the kind of radio wave radiation associated with Wi-Fi could have a variety of negative health effects,” says Joel Moskowitz, director of the Center for Family and Community Health at the University of California, Berkeley. (Moskowitz has collected much of that research here.)
This study was aimed at investigating the alteration of antibiotic resistance of Klebsiella pneumonia, after exposure to Wi-Fi 2.4 GHz electromagnetic radiofrequency radiation from a Wi-Fi router for 3, 4.5 or 8 hours. The findings of this study show a statistically significant rise in the sensitivity of Klebsiella pneumoniae to different antibiotics after 4.5 hours of exposure to 2.4 GHz Wi-Fi radiation, followed by a fall after 8 hours of exposure. These observations can be interpreted by the concept of non-linearity in the responses of Klebsiella pneumoniae to different antibiotics after exposure to electromagnetic radiofrequency radiation.
RESULTS: The results revealed that long-term exposure of 2.4 GHz Wi-Fi radiation can alter expression of some of the miRNAs such as miR-106b-5p (adj p* = 0.010) and miR-107 (adj p* = 0.005). We observed that mir 107 expression is 3.3 times and miR- 106b-5p expression is 3.65 times lower in the exposure group than in the control group. However, miR-9-5p, miR-29a-3p and miR-125a-3p levels in brain were not altered.
Sexting: The vast majority of kids are smart and don’t take, send, or post or even store nude photos of themselves or peers on their phones. People who do so can be charged with production, distribution, or possession of child pornography, a serious crime. They can also be subjected to jokes, bullying, blackmail, expulsion from school, loss of a job, etc. and the images can circulate forever. Just don’t go there.
Within a relatively short time, WiFi has increased its presence in homes, offices, public spaces, coffee shops, various modes of transportation, schools, hospitals, and throughout the world. WiFi is an integral part of our lives, and it has provided unimaginable convenience: We can get information instantly, and work from most anywhere with a laptop. 
Sixteen years later, cell phones -- with 6 billion subscriptions worldwide and counting -- have revolutionized how we communicate. The technology that powers them has changed just as dramatically. Today’s smartphones vibrate, rock out, show high-def movies, make photos and videos, issue voice commands, check email, go underwater, navigate with global positioning systems and surf the web in 3-D. They sport dual core processors and batteries that let you – or your kid -- talk for close to 20 hours. (The StarTac maxed out at just 3 hours.)

Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer. [18] According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased." [19] According to a May-June 2012 meta-study in the Journal of Andrology, "men using mobile phones have decreased sperm concentration" in addition to "decreased viability" of their sperm. [64]
Although uterine lipid peroxidation increased in the EMR groups, uterine glutathione peroxidase activity (4th and 5th weeks) and plasma prolactin levels (6th week) in developing rats decreased in these groups. In the maternal rats, the plasma prolactin, estrogen, and progesterone levels decreased in the EMR groups, while the plasma total oxidant status, and body temperatures increased. There were no changes in the levels of reduced glutathione, total antioxidants, or vitamins A, C, and E in the uterine and plasma samples of maternal rats.
What a dishonest shit article. There is no evidence that Wi-Fi does anything mentioned here. I read one of your “citations” about its link to insomnia and the study you link doesn’t even come close to mentioning WiFi. Your vague “link to cancer” citation is a local news piece. This kind of shit just reinforces people’s pseudoscientific nonsense beliefs.
The easiest thing for you to do is to put a passcode on your phone. Having a passcode will make it harder for someone to pick up your phone to scroll through, access your accounts, or install something malicious. In the event that your phone gets stolen or you lose it, it’ll make it a bit harder for others to get into your phone. Most phones just ask for a 4-digit passcode, but some phones will allow you to use a more complex passcode.
The presented data collectively suggest that microwave irradiation constitute a stress to the plants, resulting in enhanced emissions of GLV, up-regulation of terpenoid emissions and modification in essential oil content and foliage anatomy. Anatomical and emission traits suggested that WLAN-frequency irradiation resulted in more severe stress than GSM-frequency irradiation, but the effect of WLAN-frequency irradiation on essential oil was inhibitory. There was an agreement between anatomical and chemical traits with anatomically most resistant species Apium graveolens being chemically least responsive.
Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
