Wide Awake at 3am, Though You Fall Asleep Fine? 7 Reasons Women Over 50 Are Clearing Out the Sleep-Aid Drawer for a Copper Disc Under the Pillow

It isn't "just stress", it isn't your cortisol, and it isn't the wrong magnesium. Here's what keeps a 3 a.m. wake going, and what the readers who are now back asleep by 3:30 changed.

The red numbers say 3-something. They usually do.

Sharon, 55, dispatches school buses outside Des Moines and is at her desk by 5:45. One night she added up her nightstand drawer: melatonin, magnesium, a "night cortisol" capsule, a pillow spray, a weighted blanket, a cooling pad, an app. $1,140 in a year. She finished the sum at 3:08 in the morning.

Every item had worked for about a week.

She was about to order one more bottle. She didn't, because of one question a pharmacist had asked her in the sleep aisle that summer. I've heard Sharon's story from so many of you that I asked what finally made the difference. Here are the seven things you told me.

The short version. Everybody wakes about five times a night; after 2 a.m. a wake is easier to stay in, and the clock and the phone keep it going. Almost everything in the drawer is built for falling asleep at 10. Readers who got past 3 a.m. stopped adding bottles, put one thing under the pillow, a copper disc from a 1934 patent, and judged it with a clock diary over 60 nights. 👇

You wake up 5 times a night. After 2 a.m., one of them sticks.

Between every cycle of sleep, the brain surfaces for a moment. Most adults wake about five times a night , and almost nobody remembers it: a wake has to last about four minutes before you remember it in the morning. 1

But the night isn't the same all the way through. Deep sleep is spent early. After 2 a.m., sleep is lighter , and a wake is easier to stay in. 2 That's why the clock always says 3-something.

So waking at 3 isn't the broken part. The broken part is the one wake that doesn't end, and what keeps it going is usually something small. More on that at number 5.

"That stopped me on the path. All those nights I thought waking up was the problem."

Kathy, 58, Tulsa
One night, five wakes 10:30 pmmidnight2 am3:155:306:15 awake ↑ deep sleep, early lighter after 2 am 3:15 · the wake that stays open Short wakes (blue spikes) end in minutes and are forgotten. After Winser et al., Sleep Medicine, 2013.

Five wakes a night is normal. One that stays open is what you notice.

The "3 a.m. cortisol spike" those capsules are sold for isn't there

Half the products in the sleep aisle are built on one story: cortisol jumps at 3 a.m. and wakes you up.

When researchers measured cortisol through the night in 201 healthy adults, at home , it was near its lowest in the small hours and only beginning its slow climb toward morning. No jump at the moment of waking. 3

You didn't imagine the 3 a.m. jolt. But a capsule aimed at a spike was aimed at the wrong thing.

"I took a 'night cortisol' capsule for five months, $64.95 a bottle, for a spike that wasn't there."

Sharon T., 55, Iowa

Five months, one bottle a month.

The pharmacist's question that half-emptied the drawer: "Can't fall asleep, or can't stay asleep?"

Sharon was standing in the sleep aisle with a magnesium bottle in each hand when the pharmacist asked her: "Can't fall asleep, or can't stay asleep?"

"Stay," she said. "I'm up at 3 every night."

"Then I'll be honest with you. Almost everything in this aisle is for falling asleep."

  • Melatonin, $9.48. Gets you under by 10:30. It doesn't promise to keep you there at 3.
  • Magnesium glycinate, $23.99. Takes the edge off at bedtime. Bedtime was never the problem.
  • Pillow spray, $31. "It smelled lovely at 3 a.m."
  • Weighted blanket, $129. Too hot. It lives in the closet.

"Every one of them worked for about a week. That's the part nobody warns you about. Everything works for a week."

Sharon T.

Built for bedtime. Sharon's came to $1,140 in a year.

The copper disc readers keep under the pillow: no pill, no light, nothing to charge

Most of the readers who got past 3 a.m. tried the free fixes first: the clock turned to the wall, the phone in another room. It helped some. But a clock turned to the wall can be turned back at 3:10, and the phone is only a few steps away. Willpower is asleep before you are.

So they looked for something that would do three things:

  1. Nothing to swallow, and nothing that touches HRT or a prescription.
  2. Already there at 3 a.m., under the pillow, with none of what keeps a wake going: no light, no sound, no clock, nothing to charge, nothing for willpower to do.
  3. Not a gimmick: something with a real history you can check.

Most of them landed on the same thing: the Lakhovsky Disc from Spirad, open copper rings from a forgotten engineer's 1934 US patent. They told me it was the only thing they found that did all three. His record is at number 6; you can check it.

  • A flat disc 3.9 inches across (10 cm), open copper rings, gold-plated, on a thin board
  • It goes under your pillow and stays there
  • Nothing to swallow, no battery, no light, no cord, no app; it sends nothing out
  • Not a medicine, never instead of yours: keep your HRT and your prescriptions

And yes, it's a circuit board. There's a $9 version online, without the guide, the diary or the 60 nights.

"I started looking for something that would be there at 3 a.m. without me having to do anything."

Sharon T.

About the size of a coaster. You can't feel it through a pillow.

Clock, phone, trying: what keeps 3 a.m. going, and what Pat reaches for instead

Late at night a wake is light, and small things keep it going. The clock : people who check it in bed worry more and lie awake longer. 4 The phone : even ordinary room light at night cuts melatonin by more than half, 5 and a phone a foot from your face at 3 a.m. is not ordinary room light. Trying : lying there willing yourself back to sleep.

Pat, a retired lab tech in Kathy's walking group, had already tried the phone in the hall. "That lasted a week, like everything else." Now the disc is under her pillow, and when she wakes, she's back under before the phone crosses her mind.

"I still wake up. I'm just back asleep before I remember to text you."

Pat, from the walking group

The Tuesday walkers' roll call, before Pat stopped answering.

The disc's rings come from a 1934 US patent, not a marketing department

The design is Georges Lakhovsky's, an engineer in Paris who spent his life on open copper rings. His 1929 book, The Secret of Life, carries a preface by Arsène d'Arsonval, one of the fathers of medical electricity. The US granted his patent, number 1,962,565, in 1934; Nature reviewed the English edition in 1940. He died in New York in 1942, and his rings were mostly forgotten. The disc follows the ring pattern his patent drew, each ring cut open so it never closes. That's the history you can check.

His idea: every living cell works like a tiny oscillating circuit, and open copper rings set close by help it keep its own rhythm through the night. That's the pattern under the pillow, and readers judge it the way he would have: with their own diaries. Joanne tells the whole story in her letter .

"My first thought was, 'This is going in the drawer too.' My second was that it came with 60 nights to try it. Not a week."

Judge it over 60 nights, in your own handwriting, not in a week

Everything in the drawer worked for a week, so don't judge this one in a week. Every order comes with a 21-night clock diary: each morning, when you woke and when you were back asleep. Look at three weeks, not one night. You have 60 nights: if your column doesn't change, send it back and Spirad refunds every cent, opened or not.

  • Week 1: usually nothing to point at. Same wakes, same times.
  • Week 2-3: readers say the second number starts coming earlier. Sharon's diary: "back by 3:30" most nights.
  • Week 5 and after: the week that matters, because everything in the drawer worked for one.

Not everyone: one woman in Kathy's group couldn't tell the difference and sent hers back inside the 60 nights. She mailed it back and they refunded her. No argument.

"Week 5, still working. That's the line I care about."

Sharon T.

Two times a morning. Keep the bad nights in.

Readers ask

Can I keep my HRT, magnesium or sleep medication?

Yes. The disc goes beside your treatment, never instead of it. It adds nothing to your body and takes nothing away. Don't change a prescription because of anything you read here.

Is this the $9 disc I can find online? Is it a circuit board?

Yes, it's a circuit board, and the rings are copper, gold-plated. A fibreglass board is the most precise way to make what the 1934 patent describes. Similar discs sell online for $9 without a guide, a diary, a 60-night trial or anyone to answer an email.

How do I know it's working if I can't feel anything?

The diary. Two times each morning, three weeks, the whole column. A watch or a sleep tracker works too. Some people notice nothing, which is why there are 60 nights.

How long does it take to arrive, and is it a subscription?

5-7 business days, with tracking. Free US shipping on 2 discs or more. You pay once; nothing renews. Returns within 60 nights: Spirad sends the return address and refunds every cent once it's back, opened or not. Return postage is yours unless the disc arrives damaged or wrong.

Is it safe with a pacemaker, a metal bed frame or a nickel allergy?

It's passive and non-magnetic: nothing in it reacts with a pacemaker, a metal bed frame or a mattress. The gold sits on a thin layer of nickel, so if you're allergic, keep it under the mattress edge or on the nightstand, where your skin never touches it. Not for children's beds.
