The Clocks Go Back This Weekend. Your Body Clock Doesn't. (Why the "extra hour" costs most people a week of sleep)
Twice a year, the whole country changes the time on the wall. Your body doesn't get the memo... and if you were already sleeping badly, this is the week it shows. Here's what's really keeping you up, and the overlooked rhythm that resets it.
Grab the purple hand and turn the clock back an hour.
Where can I buy this?
01:00 The hour you live twice
The "extra hour" is a myth. Most people know it by Wednesday.
Sunday feels like a gift. An hour back, a lie-in for free. Then Monday arrives and something is off.
You're wide awake at 5am, staring at the ceiling, an hour before the alarm. By 9pm you're fighting to keep your eyes open on the sofa. You go to bed "on time" and lie there. Lunch feels early, dinner feels late, and the afternoon slump turns up an hour ahead of schedule.
And if your sleep was already patchy before the change (we know, that's most of us), it doesn't just wobble for a night. It unravels for a week.
That's roughly how much extra sleep researchers found people actually get from the autumn clock change. A 2013 review in Sleep Medicine Reviews found little evidence of extra sleep on the night itself, and evidence of a net loss of sleep across the week that follows.
So where does the hour go? Your body never agreed to the change in the first place.

Wall clock vs body clock
Set your usual bedtime, then slide through the week after the change. The second clock is the one your body is actually running on.

23:47 Why your body won't just switch
Your body clock was never set by the clock
In 2007, a German team led by chronobiologist Till Roenneberg looked at the sleep of 55,000 Europeans. Their finding was simple and a bit unsettling: on free days, people's sleep followed the seasonal progression of dawn, not the time on the wall. The body runs on natural signals. The clock on your phone is just a suggestion.
Which raises the bigger question. If your body sets itself by nature's rhythms... what happens when you spend almost all of your time somewhere those rhythms can't reach?
40 adults who had lived with insomnia for 9.7 years on average, over 4 weeks. Some slept with a Schumann-frequency device, the rest were in a placebo group. Nobody knew which group they were in.
Not a survey, not a feeling. Measured with EEG and polysomnography in a sleep lab, against a placebo group.
23:59 A thought experiment
If all of human history were a single day
Squeeze our 300,000 years as a species into 24 hours. Tap a moment to see where it lands on humanity's clock.
The pink sliver on the dial (enlarged so you can see it) is the modern, indoor, wired way we sleep now.
For 23 hours, 59 minutes and about 18 seconds of humanity's day, people slept inside the Earth's natural rhythm. The way we sleep now fits into the last 42 seconds.
Here's the part that matters for your bedroom. Concrete, steel, insulation and wiring all weaken that natural 7.83 Hz signal indoors. And between the dark evenings and the cold, the weeks after the clocks go back are when we spend more time inside than at any other point in the year.
So right when your body clock is trying hardest to reset, it has less to reset against.
That's the difference between the person who shrugs off the clock change by Tuesday, and the one still wide awake at 3am the following weekend. Same hour. Different room.
01:15 Still awake
What's on your nightstand?
Everything you've tried for sleep does something real. That's why you keep buying it. But flip each one over and you'll see the same blind spot.
Tap each card to flip it.
And the oldest trick of all
Go on, count a few. Tap the field or the button.
Counting sheep has been the go-to advice for centuries.
A Schumann field in the bedroom doesn't knock you out or cover anything up. It restores the steady background rhythm your body clock evolved with, silently, all night, every night.
Everything on your nightstand helps you through the night. Only one thing changes the room you're sleeping in.

05:30 The device
Meet The Schumann V3
The Schumann V3 puts a silent 7.83 Hz field on your bedside table, as a steady part of your evening routine, clock change or not.
But 7.83 Hz is where it starts, not where it stops. The Schumann V3 tunes anywhere from 0.01 to 9,999.99 Hz, so you can set it to the slow delta range, 0.5 to 4 Hz, the brainwaves of deep sleep. Save your setting to one of its 5 preset buttons, and bedtime becomes a single press.
It's a silent coil with no speaker, so there's nothing to hear and nothing to wear. One charge lasts up to 24 hours, so there's no cable on the nightstand. And it's palm-sized and portable, so hotel nights and long flights get the same setup as home, which is the other time your body clock gets thrown.
The Schumann V3

- Starts at the Earth's 7.83 Hz
- Delta sleep settings, 0.5 to 4 Hz

The clocks will change again this weekend, and again in the spring, whether you're ready or not. You can't stop that.
What you can change is the room your body is trying to reset in. Set it up now, before the change, and give your body clock something steady to come back to. If you don't sleep better within 30 days, send it back.
The clocks change twice a year. Your rhythm doesn't have to.
