We came across a Facebook Reel that had been shared thousands of times, claiming that electric vehicles (EVs) expose occupants to dangerous levels of electromagnetic fields (EMF), likening them to “sitting in a microwave”. The video links this alleged exposure to fatigue, brain fog, hormone disruption and nervous system overload. It also promotes products such as EMF-blocking jewellery and phone stickers as protection from these purported effects of EMF exposure.
EV adoption is growing worldwide, including in Singapore. In 2025, EVs made up 45% of all new car registrations in Singapore. This trend reflects the government’s broader efforts under the Singapore Green Plan, to have all new car and taxi registrations be cleaner-energy models from 2030, and to achieve a fully cleaner-energy vehicle population by 2040. As EVs become increasingly common on Singapore roads, claims about their health effects warrant closer scrutiny, which prompted us to look into this one.
What are electromagnetic fields?
Electromagnetic fields are invisible areas of energy produced wherever electric current flows, and they exist on a spectrum. EMF exposure is often grouped into two categories: ionising and non-ionising radiation.
Ionising radiation (also known as high-level radiation), such as X-rays and radioactive materials, has the potential to cause adverse health effects such as cancer and cellular damage, with prolonged exposure.
Non-ionising radiation (also known as low-level radiation), by contrast, includes low-frequency fields from sources like power lines and vehicle electronics, as well as radiofrequency fields emitted by Wi-Fi, Bluetooth, and mobile networks like 5G. Unlike ionising radiation, non-ionising radiation does not carry enough energy to break chemical bonds or damage DNA.
This is not the first time we have encountered claims about EMFs. We have previously examined similar concerns around everyday technologies, including AirPods and 5G networks, and have consistently found that current evidence does not show a clear link between non-ionising radiation and adverse health effects.
The broader scientific consensus does not support the level of alarm suggested by such posts. Organisations such as the World Health Organisation (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP), an independent body that provides guidance on exposure limits, maintain that typical exposure levels from consumer technologies remain well within established safety thresholds.
What the science says about EV EMF levels
EVs, by virtue of their high-voltage batteries, power converters and electric motors, do produce non-ionising EMFs, primarily in the extremely low-frequency (ELF) range.
In 2025, Germany’s Federal Office for Radiation Protection (BfS), a government scientific agency, published what it described as a detailed study measuring magnetic fields in and on electric cars and motorbikes, including electric, plug-in hybrid and conventional combustion vehicles, under real driving conditions such as acceleration, braking and constant speed.
The study found that all vehicles complied with recommended safety limits for magnetic field exposure. It also concluded that occupants of electric vehicles are not exposed to stronger magnetic fields than those in conventional or hybrid cars.
Moreover, a November 2025 peer-reviewed analysis in the Journal of American College of Cardiology: Asia, by a group of researchers from Indonesia, examined existing evidence on EMF exposure in EVs and cardiovascular health. It found no evidence of immediate cardiovascular risks, with most studies indicating exposure remains within international safety standards.
While the post suggests that EVs are uniquely dangerous compared to conventional cars, this is misleading. Petrol vehicles also generate EMF from onboard electronics, wiring and electrical systems, and existing measurements do not support the suggestion of elevated risk in EVs.
How about the claimed symptoms?
The post lists fatigue, hormone disruption and nervous system overload as consequences of EV EMF exposure, but these are not supported by available evidence.
On hormones specifically, the ICNIRP has reviewed laboratory and epidemiological research on both direct and indirect effects of EMF exposure. It found no evidence that the neuroendocrine system, including circulating hormone levels, is adversely affected by 50–60 Hz fields, which are similar to those found in many everyday electrical environments, including in countries such as Singapore, where the power grid operates at 50 Hz.
On neurological effects, a peer-reviewed analysis drawing on over 70 years of research found no confirmed health consequences from low-level EMF exposure. It also highlights that concerns about EMFs can produce “nocebo effects,” where expecting harm can itself lead to perceived symptoms such as fatigue or headaches.
The products being sold: the real story
The post also recommends products such as EMF jewellery and phone stickers as protection against harmful EMF levels. However, the US Federal Trade Commission has specifically warned consumers that EMF-related products are often marketed without credible scientific evidence to support their claims. Independent testing has also shown that such devices do not measurably reduce EMF exposure.
Taken together, the scientific evidence on EMF exposure in EVs, alongside the lack of effectiveness of the products being promoted, does not support the claims made in the post. Overall, the claim that EVs are harmful due to EMF exposure is misleading, and the recommended “solutions” are unsupported by scientific evidence. Therefore, we rate this claim as false.
How to spot this kind of claim
The account that posted the Facebook Reel presents itself as a wellness resource while also promoting a range of products. It invites users to comment to receive product details and links (e.g. “Comment EMF and I’ll send you exactly what I use”), a tactic that increases engagement and enables direct messages where products can then be pitched or sold, indicating commercial intent beyond informational content. The post follows a familiar pattern of amplifying concern about an alleged hazard, listing common and non-specific symptoms often without proper evidence, and then offering products as a solution.
More broadly, such posts can be usefully assessed by looking at whether they cite credible scientific evidence, clearly explain key scientific distinctions, and disclose any commercial interests behind the claims. Where questions about health risks arise, it is advisable to refer to qualified healthcare professionals or established public health authorities rather than relying solely on online sources.
