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.
An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones."  A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents.  Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors.      
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.
"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."
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”.
