Acute exposure of rabbits to WIFI increased heart frequency (+22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that WIFI induced a combined increase of PR and QT intervals. By contrast, the same exposure failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50 ml/kg) and epinephrine (0.50 ml/kg) under acute exposure to RF we found that, WIFI alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control. 

The purpose of this study was to investigate the oxidative damage and protective effect of garlic (daily 500 mg/kg during study period) on rats exposed to low level of electromagnetic fields (EMF) at 2.45 GHz Microwave radiation (MWR) for 1 h/day for 30 consecutive days. Researchers concluded that low level EMF at 2.45 GHz MWR increases the DNA damage in both brain tissues and plasma of the rats whereas it increases protein oxidation only in plasma. They also be argued that the use of garlic decreases these effects.

The present study investigated the influence of 2.4GHz electromagnetic fields, similar to that emitted by Wi-Fi system, on human brain activity. The presence of radiation had no effect on the energies of alpha and beta band of male subjects, while it reduced these energies of female subjects, resulting in significantly lower energies, as compared to those of males. Delta and theta band energies did not experience any noteworthy effect from gender, radiation condition and their interaction. Conversely, there was a significant interaction effect (gender x radiation) on the energies of alpha and beta rhythms. The present data support the idea that Wi-Fi signal may influence normal physiology through changes in gender related cortical excitability, as reflected by alpha and beta EEG frequencies.
Microwave News’s Slesin speculated on potential explanations for the NTP’s apparent backtracking: new leadership within the program, where a former drug-company executive, Brian Berridge, now runs the day-to-day operations; pressure from business-friendly Republicans on Capitol Hill and from the US military, whose weapons systems rely on wireless radiation; and the anti-science ideology of the Trump White House. The question now: Will the scientists doing the peer review endorse the NTP’s newly ambivalent perspective, or challenge it?51
Prenatal exposure to radiation from cell phones may increase the risk of ADHD and other behavior problems in children. According to a peer-reviewed Nov. 2008 study in the journal Epidemiology, exposure to cell phone radiation while in the womb "was associated with behavior difficulties such as emotional and hyperactivity problems around the age of school entry." [65] A Dec. 2010 study replicated those findings. [67] A peer-reviewed Mar. 15, 2012 study found that mice exposed to cell phone radiation in the womb "were hyperactive and had impaired memory" as adults. [66]
Nevertheless, a group of scientists got together in the mid-2000s, calling themselves the BioInitiative Working Group. This group, which largely consisted of wireless radiation researchers, has written a harsh reply as feedback to the reports claiming that posed no health risks.  The reply lists a wide range of health effects scientists at the European Commission have unfortunately either ignored or dismissed.
