If you’re searching for a way to sleep forever, you’re likely looking at one of two things: the philosophical dream of an eternal, restful slumber or the high-tech, slightly sci-fi world of cryonics. We’re going to talk about the latter. It’s the idea that when the body finally quits, we can just... pause. Hit the stop button. Wait for a future where "dead" is just a temporary medical condition that a clever doctor can fix with some nanobots and a warm compress.
It sounds like a movie plot. Honestly, it kind of is. But for people like James Bedford—the first person to ever be "suspended"—it’s a very real $200,000 bet on the future.
Cryonics isn’t about being a popsicle. That’s a common misconception. If you just froze a human body, the water in your cells would expand, turn into jagged ice crystals, and shred your insides like a blender. You wouldn't be sleeping; you’d be mush. To how to sleep forever in a way that actually matters, scientists use a process called vitrification. They replace your blood with medical-grade antifreeze. It’s a delicate, high-stakes race against the clock that begins the second a heart stops beating.
The Cold Hard Truth About Cryopreservation
Let’s get technical for a second. When we talk about how to sleep forever through cryopreservation, we’re talking about the Alcor Life Extension Foundation or the Cryonics Institute. These aren't just warehouses. They are facilities filled with "dewars"—massive stainless steel thermoses filled with liquid nitrogen.
You aren't "frozen" at $0$ degrees. You are cooled to $-196$°C. At that temperature, molecular motion stops. Biology pauses. You aren't aging. You aren't decaying. You are, for all intents and purposes, suspended in a state of clinical stasis that could theoretically last for centuries.
But there is a catch. A big one.
The legal system sees you as dead. The second your heart stops and a doctor signs that paper, you are legally a "patient" in the eyes of cryonicists, but a corpse in the eyes of the law. This creates a massive logistical headache. To ensure the brain remains intact, a standby team usually has to be at your bedside the moment you pass away. They start "cardiopulmonary support" immediately—not to bring you back, but to keep oxygen flowing to your brain so the cells don't start melting down.
Why We Can't Wake Up Yet
If we can put people into this long-term sleep, why haven't we woken anyone up?
The tech doesn't exist. Simple as that.

We can vitrify embryos. We can vitrify stem cells. We can even vitrify a rabbit kidney and bring it back to a functional state, as demonstrated by researchers at 21st Century Medicine. But a whole human? That’s a different beast. The brain is the most complex structure in the known universe. Mapping the connectome—the trillions of neural connections that make you you—is a task we've barely started.
Dr. Ken Hayworth, a neuroscientist and president of the Brain Preservation Foundation, often speaks about the "structural integrity" of the brain. The goal of those trying to figure out how to sleep forever isn't just to save the meat; it's to save the information. If the memories are gone, the "sleep" wasn't a pause—it was an ending.
There are critics, of course. Lots of them.
Bioethicists argue that cryonics is a "scam" targeting the wealthy and the terrified. They point out that we have no clue if the vitrification chemicals themselves are toxic to the point of being irreversible. It’s a fair point. We are currently pouring chemical cocktails into people's veins that would definitely kill a living person. We're betting that "Future Tech" will have the antidote.
The Cost of the Long Nap
You can’t just decide to do this on your deathbed and hope for the best. It takes planning. And money. Lots of it.
Most people pay for their "eternal sleep" through life insurance policies. You name the cryonics provider as the beneficiary. For a basic setup at the Cryonics Institute in Michigan, you’re looking at about $28,000. If you want the "whole body" treatment at Alcor in Arizona, that number jumps to $200,000 or more.
Why the price gap?
Maintenance. You're paying for someone to top off your liquid nitrogen for the next 100, 200, or 500 years. You’re paying for a trust fund that ensures the lights stay on and the dewars stay cold even if the economy collapses or the company changes hands. It is the ultimate long-term investment.

Biostasis and the Future of Medicine
Maybe you don't want to be a head in a jar for five centuries. Maybe you just need to "sleep" for a few days to survive a trauma.
This is where the science gets really cool and a bit less "fringe." Doctors at the University of Maryland have experimented with something called Emergency Preservation and Resuscitation (EPR). They essentially replace a patient's blood with ice-cold saline to rapidly cool the body to about 10°C to 15°C.
This isn't for fun. It's for people who have been shot or stabbed and have lost so much blood their heart has stopped. By cooling them down, surgeons buy time—maybe an hour—to fix the damage before the brain dies from lack of oxygen. It’s a form of temporary "sleeping" that is already saving lives.
Samuel Tisherman, the professor leading this, doesn't like the term "suspended animation." He thinks it sounds too much like Star Trek. But that’s exactly what it is. It’s a bridge.
Is "Sleeping Forever" Actually Possible?
Honestly? We don't know.
If you look at the laws of physics, there’s nothing that says we can't repair a vitrified body. It’s just an engineering problem. But it’s an engineering problem on a scale we’ve never tackled. We’d need molecular-level repair bots. We’d need to be able to regrow organs or 3D-print a new body and "upload" the preserved brain data into it.
It sounds far-fetched until you realize that 100 years ago, an organ transplant was considered black magic.
The biggest risk isn't the science; it's the sociology. Will a society 200 years from now really want to wake up a bunch of people from the 2020s? What would we even contribute? We’d be like Neanderthals trying to use a smartphone. We would be a massive burden on a future civilization.

Practical Steps for the Curious
If you’re genuinely interested in the logistics of long-term preservation, you shouldn't just Google it and hope for the best. This is a legally complex field that requires specific estate planning.
First, look into the primary organizations. Alcor and the Cryonics Institute are the big players in the US. Tomorrow Biostasis is a newer, very tech-forward option in Europe. They all have different philosophies and price points.
Second, read the literature. The Prospect of Immortality by Robert Ettinger is the "bible" of the movement. It’s dated, sure, but it sets the stage. For a more modern, skeptical, but deeply researched view, look at the work of Dr. Max More.
Third, talk to your family. If you sign up for cryopreservation and your next of kin hates the idea, they might sue to stop it. This happens more often than you’d think. "How to sleep forever" is a goal that requires your inner circle to be on board, or at least to respect your weirdest wishes.
Lastly, consider the "Neuro" option. If $200,000 is too steep, some people choose to only preserve their head. The idea is that if we have the tech to fix a frozen body, we definitely have the tech to grow a new one from your DNA. It's a bit more "Futurama," but it's a way to cut the costs in half while still keeping the part of you that actually matters—your mind.
Whether cryonics is a doorway to the future or just a very expensive way to be buried, it remains the only "out" we currently have. It’s a gamble. It’s a "hail Mary" pass at the end of the fourth quarter. But for those who aren't ready for the lights to go out, it's a sliver of hope that the sleep doesn't have to be the end.
To move forward with this path, you need to secure a life insurance policy specifically structured for "final expense" or "whole life" that covers the high costs of suspension. Reach out to a specialized attorney who understands "Uniform Anatomical Gift Act" (UAGA) filings to ensure your body isn't autopsied, as an autopsy typically destroys the brain and makes preservation impossible. Finally, join a local "standby" group if you live far from a major facility; these volunteers are trained to start the cooling process immediately, which is the single most important factor in a successful preservation.
