If you’re thinking of buying a phone case with ‘radiation blocking material’ believing it will reduce radiation, you should know this: Phones have automatic power control, such cases act as shields  and make the phone work harder, transmitting more power, increasing heat and reducing battery life, The incoming signal to the phone will also be reduced so your phone may not work in areas of poor signal.
“If you’re experiencing eye discomfort, make your phone’s font size bigger. Mark Rosenfield, O.D., Ph.D., told Men’s Health that phone users should try to hold their phones at least 16 inches away from their faces. Every few minutes look up from your screen at something far away for short breaks, and don’t forget to blink.” – Amanda Hawkins, 5 Seriously Bad Side Effects of Your Smartphone Addiction, Good Housekeeping; Twitter: @goodhousemag
TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 −) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.
This study investigated the effects of 2.45 GHz microwave radiation (exposed once or repeatedly – ten times in two weeks) on the cellular activation within the paraventricular nucleus of the hypothalamus, extracted from rat brains. High SAR triggered an increase of the c-Fos marker 90 min or 24 h after radiation, and low SAR resulted in c-Fos counts higher than in control rats after 24 h. Repeated irradiation at 3 W increased cellular activation of PVN by more than 100% compared to animals subjected to acute irradiation and to repeated non-radiated repeated session control animals. The results suggest that PVN is sensitive to 2.45 GHz microwave radiation at non-thermal SAR levels.

The present study aimed to investigate the effects of chronic low-intensity microwave exposure (900, 1800 or 2450 MHz for 180 days) on cognitive function, heat shock protein 70 (HSP70), and DNA damage in the rat brain. The results showed declined cognitive function, elevated HSP70 level, and DNA damage in the brain of microwave-exposed animals. The results indicated that, chronic low-intensity microwave exposure in the frequency range of 900 to 2450 MHz may cause hazardous effects on the brain.
You can actually get a completely mechanical timer on Amazon for super cheap. Then all you have to do is plug your router into it, and set a time period, say from midnight to 7 am, and it will automatically turn your router off and then back on again. Depending on your sensitivity to EMF radiation, you could quickly notice better and more restful sleep.

"Love it...S8 Good...Dropped it a few times no cracks with rhis case so far, cool leds tell time or do a little dance of music whenever you do close it, it saves my battery as well because ir prevenrs the screen from turning on when rhe case is on which prevents always on display...It's a great case, the led notifications and functions are handy, it protects the phone really well; the problem is that we bought Dex and having to remove the case to be able to use Dex with my phone is a bummer; if not this will be a 5 stars review."

This study investigated the effect of 2GHz EMR (1h) on the growth dynamics of Myriophyllum aquaticum (Parrot feather) by measuring the nanometric elongation rate fluctuation (NERF) using a statistical interferometry technique. After continuous exposure to EMR, M. aquaticum plants exhibited a statistically significant reduction in NERF standard deviation, therefore, the reduced NERF was due to a non-thermal effect caused by EMR exposure. The alteration in NERF continued for at least 2.5 h after EMR exposure and no significant recovery was found in post-EMR NERF during the experimental period.
MATERIALS AND METHODS: Adult male Sprague-Dawley rats in the weight range of 230 to 260 g were divided into control, sham, Wi-Fi exposed groups. After long term exposure (4 h/day for 45 days) to Wi-Fi electromagnetic radiation, plasma levels of glucose and insulin during intraperitoneal glucose tolerance test were measured. Islet insulin secretion and content, lipid peroxidation and antioxidant status in pancreas of rats were determined.
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
