Your WiFi router transmits microwave radiation in a full 360 degree sphere, around the clock, whether you're using it or not.

A Faraday cover works by absorbing and redirecting most of that radiated field back toward the router itself, rather than out into the room where you sleep, work or sit. Phones, laptops and smart TVs nearby still connect without any noticeable drop in signal.

It's a one-time install: fit it over the router and forget about it. No apps, no settings, no maintenance.

For the cost involved, it's one of the simplest, most measurable ways to reduce your daily RF exposure at home.

A recent news story about a homeowner quoted thousands of pounds to relocate a smart meter got us thinking: the price tag is the real issue here, not the meter itself.

Field strength from a smart meter follows the inverse square law: double the distance, and exposure drops to a quarter. In our home surveys, we routinely measure 8mG at the cupboard door falling to under 1mG at just 2 metres away. Relocating hardware is rarely necessary.

Our recommended order of action, cheapest first:

Move any bed or desk off the wall backing onto the meter cupboard. This layout is the single biggest factor we see.

Fit a sheet of shielding fabric or paint behind the meter, facing into the house. Done well, this can cut transmitted field by 90% or more, depending on mesh density and frequency.

Only consider a full Faraday enclosure if steps one and two don't bring your sleeping position under 1mG.

Most people assume moving the meter is the only fix. It's also the most expensive, and usually unnecessary.

When it comes to phone chargers, wattage rating tells you less than you'd think. What actually matters for EMF output is the transformer geometry inside.

A 5W linear toroid transformer runs quieter, electromagnetically speaking, than a 20W switching brick plugged into the same wall socket. Switching supplies chop mains current at high frequency to shrink the transformer, which is efficient but noisy. Linear toroids convert power at 50Hz with a simple, symmetrical winding, producing a much lower field.

Our charger uses a 12W linear transformer: enough current for a fast iPhone charge, low enough in EMF output to sit comfortably on a nightstand overnight, close to where you sleep.

If you're trying to reduce night-time EMF exposure without giving up convenient charging, this is a straightforward place to start.

Children's phone radiation exposure isn't a future problem. It's happening tonight, in bedrooms across the UK.

A child's skull is thinner and their tissue holds more water than an adult's, so radiofrequency energy penetrates deeper relative to brain size. Exposure limits were set using an adult head model from 1996, before anyone imagined handing a 7-year-old a phone. That model has never been updated for smaller heads.

The good news: you don't need to wait for policy to catch up. Distance is the biggest lever available, and it follows an inverse-square curve. Double the distance from a transmitting device and exposure drops to a quarter. Halve it and exposure quadruples.

Practical steps for tonight: no phones or tablets on or under pillows, ever. Keep the wifi router at least 3 metres from any bed. Put tablets on airplane mode for downloaded video, wifi isn't needed to play a saved file. Check whether your baby monitor is DECT (near-constant pulsed emission) or analogue/eco-mode, the difference in duty cycle is significant.

None of this needs new hardware, just switches most parents don't know exist.

A recent study on children's nightlights confirmed something we measure in adult bedrooms every week: it isn't about light versus dark. It's about wavelength.

We tested this on a client's toddler nightlight: a 470nm blue-white LED reading just 0.3 lux at the cot. Low enough that nobody thought twice about it. But melanopsin, the receptor governing your circadian clock, responds to blue light at intensities far below what your eyes register as "bright." The child was waking at 2am and 4am. Parents assumed teething.

We swapped the bulb for a flame-spectrum equivalent with genuinely zero output below 500nm. Same low lux, but it stopped suppressing melatonin altogether. We see this pattern repeatedly with router LEDs and standby lights in adult bedrooms too: people dim them, but never check their colour.

A dim blue light can do more circadian damage than a bright red one.

Tonight, don't just dim your nightlights and standby LEDs. Check their colour.

A power line survey team recently turned up in a Wisconsin county after locals raised concerns about a new transmission corridor. Good instinct, but often the wrong question. It's not "is there a line nearby" that matters, it's "what's the field strength at your actual address, right now".

Magnetic fields from overhead lines fall off roughly with the square of distance. Move from 15 metres to 30 metres and the field drops to a quarter, not a half. That's why blanket setback rules miss the point, and why two houses on the same street can show very different readings depending on which side of a transformer they sit.

A basic gaussmeter costs under £30. Walk it through your bedroom before you argue with a utility company. If it reads above 2 mG where you sleep 8 hours a night, that's the number worth acting on, not the pylon on the horizon.

We carry out home EMF surveys and offer Faraday shielding where readings warrant it. Measure first, then decide. More at nativeemf.co

A measured fact that surprised us during home EMF surveys: most domestic dirty-electricity readings do not come from the LEDs themselves. They come from the drivers powering them.

Cheap LED downlight drivers switch at high frequency and oscillate. Those harmonics ride straight onto the mains wiring, spreading electrical noise through circuits well beyond the fitting itself.

The fix is not complicated. Better-quality drivers with proper filtering cost around £3 more per fitting, and they largely eliminate this source of dirty electricity. For anyone renovating, rewiring or simply replacing downlights, it is a small spec change worth asking for.

If you are curious what is happening on your own circuits, our home EMF surveys measure this directly rather than guessing. We also stock flame-spectrum bulbs designed around lower EMF and better light quality.

A small honest fact about blue-blocking glasses: orange-tint lenses do block blue light. But they also block far more of the green and yellow spectrum than is actually necessary, leaving the world looking flat and dim.

BlueBloc lenses take a more precise approach. Rather than filtering broadly, they use a notch filter targeted specifically at 450 to 495nm: the exact wavelength range implicated in suppressing melatonin production and disrupting circadian rhythm.

The result is straightforward. You see more of the room around you, with colours staying closer to true. You still get the full circadian benefit, without the tunnel-vision orange tint.

It is a small distinction, but it is the difference between a lens designed around a marketing claim and one designed around the actual photobiology.

A new router feature from a major broadband provider turns your WiFi signal into a motion sensor, detecting movement by reading disruptions in the signal itself. To do that, the router needs steadier, more continuous transmission rather than less, which means it can register you walking past at 2am.

WiFi exposure isn't constant by default. It pulses in line with data demand. A presence-detection feature raises the duty cycle by design, because it needs continuous channel data to compare against in order to spot movement.

The practical fix is placement, not panic. Distance-squared physics means a lot: move a router from 30cm off your headboard out to 1.2 metres, and RF density at the pillow drops to roughly a tenth, not a half. In our own measurements, we've recorded 4 to 6 mW/m² at a pillow 30cm from a router, dropping to under 1 mW/m² past a metre away.

If you don't use the motion-detection feature, switch it off in the app, and hardwire what you can overnight with ethernet.

India has just doubled its permitted EMF radiation ceiling to speed up 5G rollout, with the story framed around coverage. The part worth understanding is exposure, and that's largely being left out.

A higher regulatory ceiling doesn't change how radiation falls off with distance. Move one metre further from a router or a smart meter and exposure drops to a quarter. Move two metres and it's down to a sixteenth. The inverse square law doesn't consult national limits.

What the higher ceiling does change is incentive: fewer, higher-output masts become more economical than denser, low-power ones. A mast running near the new limit 200 metres from your bedroom wall matters more to your actual exposure than any national average.

There's a simple, no-cost step available tonight: check which wall of your bedroom faces the nearest mast or sits closest to your router, and shift the bed a metre off it if you can.

It's worth asking whether exposure limits should be set around network economics, or around the worst case: a bedroom pressed against a mast-facing wall.
