The answer is yes, it can. Will it always make people sick? No. Dr. George Carlo explains that there is most definitely a biological response to what he refers to as Information Carrying Radio Waves (ICRW-energy fields from many wireless devices). When you're exposed to ICRW a process of adaptation and compensation occurs in your body. He has a great program that can help people adapt.
Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m2 ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10-3 and 0.13 × 10-1.
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.

Although mainstream outlets may ignore the proven dangers, especially in the US and Canada, researchers have identified several methods that can offer a level of defense. First off, reduced melatonin seems to correspond with exposure. Thus, increasing melatonin through supplementation may help offset some of the effects.    In animal tests, L-Carnitine provides antioxidant support for nutrients negatively affected by 2.4 GHz radiation.  
“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
This overview shows that effects of 2.45 GHz radiation have been found by different research teams, repeatedly, in different study objects, and at different exposure levels. A broad spectrum of issues has been investigated such as the effects of 2.45 GHz radiation emitted by a Wi-Fi router on the release of mercury from amalgam fillings. The mercury levels were significantly increased (Paknahad et al. 2016).
Central to keeping the scientific argument going is making it appear that not all scientists agree. Again like the tobacco and fossil-fuel industries, the wireless industry has “war gamed” science, as a Motorola internal memo in 1994 phrased it. War-gaming science involves playing offense as well as defense: funding studies friendly to the industry while attacking studies that raise questions; placing industry-friendly experts on advisory bodies like the World Health Organization; and seeking to discredit scientists whose views depart from the industry’s.21
DefenderShield Cellphone Radiation Case also claims independent testing and says in their website: That a "sophisticated layering of separate non-toxic, human safe materials processed for maximum radiation blocking efficiency. Each material has unique and targeted radiation-shielding characteristics designed to work in unison to eliminate all radiation emissions from 0 to 10 GHZ and Defender Shield technology refracts, conducts and finally absorbs all these potentially harmful emissions." In this demonstration, the radiation level measured when DefendeShield case was on is still quite a bit above the level of exposure that I would recommend. I personally do not recommend-holding a phone with a shielding case to your head as the DefenderShield website shows a young woman doing as she demonstrates the product.
Lloyd Burrell was running a successful small business when one day in 2002 he began to feel unwell when using his cell phone. Within a matter of days he developed highly debilitating symptoms when using his phone, computer, and all types of electromagnetic devices in his home and workplace. When his doctors and the medical community drew a complete blank, Lloyd set out to find his own solutions. Lloyd has now made it his life mission to raise awareness about the dangers of electromagnetic fields (EMF) and share the remarkable discoveries he’s made on his quest to recover his health. Lloyd writes for numerous magazines and websites, hosts EMF teleseminars, and is a regular guest on radio shows and other events.

It’s worth remembering that Wi-Fi occupies the same part of the spectrum as microwaves, which sounds terribly alarming. If it can boil water, surely it’s bad for us too? Well, no. Not at such low power. This is also the frequency of the cosmic background radiation, the echoes of the big bang that fill the sky. There is literally nowhere in the universe that does not have microwaves pinging around in it.
