Do EMF-blocking products work? Separating helpful from hype
Nothing but 'net.
Electromagnetic fields are all around us — power lines and household appliances produce extremely low frequency EMFs, whereas cell phones and Wi-Fi devices emit radiofrequency EMFs.
The general consensus in the medical and scientific communities is that low-frequency EMFs do not pose a significant health risk, while research continues into the effects of radiofrequency EMF exposure.

Growing concerns about the dangers of EMFs have fueled an onslaught of products designed to block radiation, from laptop pads, phone stickers and shielding paint to hooded ponchos and even silver fiber skivvies.
In a market saturated with EMF-protection gadgets, knowing what actually works — and what's just shiny garbage — is harder than ever.

Functional medicine practitioner Will Cole, who advises Gwyneth Paltrow and other celebs, told The Post he takes a 'middle ground view' on EMF mitigation.
He leaves his cell phone outside his bedroom when he sleeps, turns Wi-Fi off at night and connects his laptop at work to the internet via Ethernet, not Wi-Fi.
He also sometimes keeps his phone in a faraday bag, designed to block radio signals such as Wi-Fi, Bluetooth and GPS. Cell phones cannot receive calls or texts in these pouches because the conductive material redistributes electromagnetic energy.
'There's enough research out there that I'm taking a more precautionary, conservative approach around it,' Cole said. 'I know more exposure isn't better. It's not helping me at all, so I want to limit it as much as possible.'

Just this week, a review of 52 animal studies suggested a potential link between cell phone radiation exposure and increased risk of certain cancers in lab animals.
The findings prompted scientists from the International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) to renew their call for governments to strengthen regulatory limits on wireless radiation.

'Since animal testing results are used by public health agencies for predicting risks to human health, these findings are a significant warning that need to be used by governments to develop science-based limits to cell phone radiation that are protective of human health,' ICBE-EMF chair Ron Melnick told The Post.
The FCC has established radiofrequency exposure limits for cell phones, Wi-Fi and cell towers, but some groups like ICBE-EMF argue these limits are outdated and insufficient to protect public health.
In the meantime, the ICBE-EMF recommends keeping cell phones out of pants pockets, utilizing landlines with wired handsets, turning cell phones to airplane mode when not in use and opting for wired internet connections like Ethernet.

Cole said everyone has to create their own healthy boundaries with technology. He likened individual tolerances for stressors to 'buckets' that can be big or small.
'A lot of people's buckets are at the brink of the tipping point, and that's when health problems ensue,' Cole explained.
Some people report experiencing headaches, fatigue, dizziness, sleep disturbances and troubles concentrating due to electromagnetic hypersensitivity (EHS), which is not widely recognized as a medical diagnosis but is gaining more awareness.

'If somebody has a smaller bucket, they may have to do more EMF mitigation. They may have to look at things like mold. They may have to look at things like their food a little bit more specifically,' Cole said.
'But some people can smoke and drink and live a long, healthy life — those are the big bucket people.'

A nervous Nelly may take drastic measures to reduce their EMF exposure. Michael McKean's whip-smart but troubled lawyer character on 'Better Call Saul' wrapped himself in a space blanket and avoided the outside world.

A chiropractor who goes by 'DoctorEMF' trained an Aussie blue heeler to pick up on his sensitivities, and a holistic health specialist at a recent biohackers conference copped to 'sleeping on an anti-aging mattress in an EMF-remediated building.'
Cole said he doesn't typically recommend buying devices to lessen EMF exposure, instead, he works with patients to make 'practical, measurable, realistic changes.'
He noted that 'there's not a lot of compelling research' supporting EMF-blocking devices, though he has found the faraday technology effective.

What's important is not going overboard and creating an 'EMF bubble.'
'Having stress and anxiety around EMF isn't good for your health,' he said. 'We want to be proactive, but not overly reactionary.'

NYC opens new front in war on rats as contraceptive program kicks off in Harlem
Rats, not tonight, honey. The city just opened its latest front on its war against its most hated rodents — lacing rat bait around the city with birth control. The program kick-started on city property in Harlem last week — and is expected to cost nearly $600,000 annually for the anti-procreation pellets and a staff of five full-timers, including a city research scientist and pest-control aide, according to City Council documents. The move comes a week after UFO-like 'Empire Bins'' were put in the same Manhattan neighborhood to try to end curbside feasts for the relentless rodents. 'We're incredibly excited and optimistic about all the containerization work we're seeing in the city because that's reducing food competition — and really reducing a rat's ability to reproduce by cutting off its food source,' city rat czar Kathleen Corradi told The Post in an exclusive interview Monday. 'What the science tells us is removal of a food source, removal of those conditions that allow them to thrive, is how we get to achieve sustained production — and we're seeing really great results in that regard,' she said. The rodent 'contraceptive stations' rely on bait designed to specifically woo rats. The contraceptive pellets slow egg production in female rats and sperm mobility in males. The effort is part of 'Flaco's Law,' which the council passed after rat poison was linked to the death of the Central Park Zoo's beloved escapee Flaco the owl. The contraceptives are in tamper-resistant contraptions and pose an extremely low risk to humans, pets or 'non-target' wildlife, a city rep said. The city Health Department will conduct monthly inspections to track signs of rats in the area, according to the legislation. Once the pilot wraps in 12 months, workers will report to the mayor and council on whether the approach has been effective at curbing rats. Citywide rat sightings reported to 311 are down each of the past six months when compared to the same time period last year, coinciding with the city's new requirements for closed-lid trash containers. But not all areas around the city have seen a decrease in rat sightings. The community-board district where the contraception pilot program is in West Harlem has seen a 7.8% jump in rat sightings compared to this time last year, according to a Post analysis of 311 data. Corradi argues that the city's efforts are only as good as property owners' compliance from waste containerization to outdoor dining regulations. '[Human] behavior change is hard,' she said. 'We are doing integrated pest management on city-owned properties, but then the 98% remaining of the tax lots that are privately owned properties, that's up to the property owners to choose what mechanisms they're doing when it comes to [rat population] control.' Corradi added that when one area has success combatting the rodents, she doesn't expect hungry rats to simply migrate to other parts of the city in search of food because the rodent species is 'by nature, hyperlocal. 'Typically, these animals don't travel 100 to 300 feet from where they're living to their food source,' she said.

Appendix cancer has quadrupled in older millennials in the US
Researchers are reporting a startling spike in appendiceal adenocarcinoma (AA) — otherwise known as appendix cancer — in people born after 1945. Cases have more than tripled in Americans born between 1980 and 1985 and quadrupled in those born between 1985 and 1990, according to a new study out of Vanderbilt University Medical Center. 'I think it's alarming,' study author Andreana N. Holowatyj, an assistant professor of hematology and oncology, told The Post. Advertisement 3 A new study has identified an alarming spike in appendiceal adenocarcinoma (AA) — otherwise known as appendix cancer — in people born after 1945. top images – Appendix cancer is very rare, estimated to affect only about one or two people per 1 million per year, according to the National Cancer Institute. Indeed, Holowatyj's team identified only 4,858 people aged 20 and over who were diagnosed with AA between 1975 and 2019. Advertisement The findings, published Monday in the Annals of Internal Medicine, are nonetheless part of a troublesome trend. AA is yet another type of cancer that seems to be on the rise in younger adults — joining the ranks of colorectal, breast, uterine, kidney and pancreatic cancers. 'I think the fact that we're seeing birth cohort or generational effects across a plethora of cancer types is indeed alarming because it really stresses the need to understand what is underpinning this pattern in order for us to be able to actively reverse it,' Holowatyj said. 3 Experts point to lifestyle changes, such as more sedentary behavior, as a possible cause of the rise in cancer cases in younger people. StockPhotoPro – Advertisement As with other cancers, health experts aren't exactly sure what could be causing the jump in AA cases. 'I think it's going to be a constellation of factors that may be driving appendiceal cancer development,' Holowatyj said. 'One of the things we often think about is, what has changed across birth cohorts over time?' she said. Advertisement Holowatyj pointed to 'possibly the use of antibiotics, both in childhood and in the food chain, the industrialization of the food industry over time, the lifestyle patterns and the tripling of obesity since the 1970s, increasingly sedentary behavior, possibly environmental exposures that have changed across different parts of the country and over time.' Whatever the cause, she hopes this study encourages the public to be 'aware of this cancer, to know about the signs and symptoms of appendix cancers and know that we're seeing more cases diagnosed across generations.' 3 Most AA cases are diagnosed incidentally after someone has their appendix removed. Avocado_studio – Many of these symptoms can mimic appendicitis: Abdominal pain, often on the lower right side Bloating, diarrhea or constipation Feeling full after small meals Unexplained weight loss Nausea and vomiting Abdominal mass or swelling Holowatyj hopes that people with symptoms 'see a healthcare professional in a timely manner because it's truly critical to detect appendix cancer early.' There are no standardized screening tests for appendix cancers — most cases are diagnosed incidentally after someone has their appendix removed. 'I think it's important to understand that appendix cancer is actually diagnosed in younger ages more commonly than we see in other cancers,' she said, noting that one in three patients diagnosed with appendix cancer is under the age of 50, compared to one in eight for colon cancer.
