What is cryonics?

Cryonics is the practice of preserving legally deceased individuals at ultra-low temperatures using a technique called vitrification. The goal is to protect the body — especially the brain — from decay so that one day, when medical science has advanced enough, the person may be revived and treated.

The cryonics process begins the moment legal death is declared and is most effective when it’s initiated immediately.

‍

Step 1: Standby and preparation

Cryonics begins before death. Cryonics providers like Tomorrow.bio deploy a standby team when a patient is terminal and nearing death.

The team:

• Travels to the patient’s location
• Coordinates with medical personnel and family
• Prepares equipment for rapid action at the time of death

This phase is crucial for ensuring minimal time between death and the beginning of preservation.

‍

Step 2: Legal death and stabilization

Once a doctor declares legal death:

• The team begins cardiopulmonary support to circulate blood and oxygen
• The body is cooled using ice packs or surface cooling devices
• Medications are administered to reduce clotting, inflammation, and cellular damage

This temporary support prevents deterioration while preparing the patient for cryoprotection.

‍

Step 3: Cryoprotectant perfusion

The patient is then transported to a surgical facility, where the body undergoes cryoprotectant perfusion:

• Blood is gradually replaced with cryoprotective agents (CPAs)
• CPAs prevent ice crystals from forming during cooling
• The solution is distributed through the circulatory system to reach all organs, including the brain

This stage is essential for avoiding the damage associated with traditional freezing.

‍

Step 4: Vitrification

After perfusion, the patient is cooled slowly to -196°C over several hours or days.

Cooling occurs in stages:

• From body temperature to -79°C in dry ice
• Then to -196°C in liquid nitrogen

At this point, the patient is vitrified — tissues are in a stable, glass-like state where biological activity ceases, and decay is halted.

‍

Step 5: Long-term storage

Vitrified patients are placed into vacuum-insulated dewars filled with liquid nitrogen. These containers:

• Do not require electricity
• Are monitored for nitrogen levels and temperature stability
• Can preserve patients indefinitely, assuming continued upkeep

At Tomorrow.bio, all patients are stored at the European Biostasis Foundation in Switzerland — a secure, medically equipped facility built for longevity and safety.

‍

Is the cryonics process reversible?

Currently, no. The cryonics process preserves structure, not life. There is no existing method to revive a vitrified human.

However, the idea is that if structure (especially of the brain) is preserved well enough, future technologies — including nanomedicine, tissue regeneration, or brain emulation — could restore life and function.

‍

Why people choose this process

Despite the uncertainty of revival, many choose the cryonics process because:

• It preserves the possibility of a second chance
• It may protects identity, memory, and consciousness
• It aligns with a future-oriented view of science and medicine
• It’s an act of agency in the face of terminal illness

People don’t expect guarantees — they want options.

About Tomorrow.bio

At Tomorrow.bio, we are dedicated to advancing the science of cryopreservation with the goal of giving people and pets a second chance at life. As Europe’s leading cryopreservation provider, we focus on rapid, high-quality standby, stabilization, and storage of terminal patients — preserving them until future medical technologies may allow revival and treatment.

Our mission is to make cryopreservation a reliable and accessible option for everyone. We believe that no life — human or animal — should end because current medical capabilities fall short.
