Ammortal Chamber vs. Cryotherapy: Which Should You Book First?

Both services are at Biohack Cryo & Wellness in Woodland Hills. Both have regular clients who treat them as non-negotiable parts of their recovery week. And if you ask those clients which one to try first, you will get genuinely different answers, because these two modalities do fundamentally different things.

This is not a ranking. The Ammortal Chamber and cryotherapy are not competing for the same goal. But if you are booking your first session at Biohack and trying to choose between them, here is what each one actually does, who benefits most from each, and how to decide based on what you are trying to accomplish.

What the Ammortal Chamber Does

The Ammortal Chamber is a multi-system recovery device that combines five clinically-backed technologies simultaneously: pulsed electromagnetic fields (PEMF) for deep cellular repair, multi-wavelength red and infrared light therapy for mitochondrial energy production, molecular hydrogen inhalation for antioxidant protection against oxidative stress, vibroacoustic sound therapy for nervous system synchronization, and guided breathwork for autonomic regulation. Sessions run 15, 25, or 50 minutes.

You recline in a zero-gravity position based on NASA body-positioning research. There is no cold, no heat, no external physical stress on the body. The experience is calm and restorative. What is happening underneath that calm is a coordinated biological response across multiple systems simultaneously. The chamber does not produce the sharp immediate jolt that some recovery modalities deliver. It produces something quieter and more sustained: a sense of restored baseline that becomes more noticeable with consistent use.

Biohack Cryo & Wellness is the only Ammortal Chamber location in the San Fernando Valley. The previous closest location was in Santa Monica.

What Cryotherapy Does

Whole-body cryotherapy at Biohack means three minutes in a chamber chilled between -166 degrees F and -220 degrees F. The extreme cold triggers an immediate sympathetic nervous system response: vasoconstriction, a surge of norepinephrine, endorphin release, and rapid reduction in acute inflammation. You exit the chamber energized, sharp, and physically lighter.

The mechanism is acute cold stress, repurposed for recovery and performance. Inflammation drops. Circulation surges when the body rewarms. The mental effect, driven by the norepinephrine and endorphin response, is immediate and pronounced. Clients consistently describe cryotherapy as the closest thing to a complete system reset in three minutes.

How They Compare Side by Side

The simplest comparison: cryotherapy activates and energizes. The Ammortal Chamber restores and rebuilds. These are not competing outcomes; they are complementary, which is why a significant share of regular clients at Biohack use both.

Session Experience

Cryotherapy is intense and immediate: three minutes of extreme cold followed by a sharp energizing response that most clients feel within minutes of exiting. The Ammortal Chamber is calm and gradual: 25 minutes of simultaneous modalities producing a quieter, deeper restoration that often takes an hour to fully settle in. Cryotherapy feels like turning a dial up. The Ammortal Chamber feels like resetting the dial's baseline.

Inflammation

Both address inflammation, but through different mechanisms and at different timescales. Cryotherapy works through the cold-shock response: rapid vasoconstriction followed by reactive vasodilation flushes inflammatory markers from tissue. The Ammortal Chamber addresses inflammation at the cellular level via PEMF, which has peer-reviewed evidence for reducing inflammatory cytokines, and via photobiomodulation, which reduces COX-2 expression and prostaglandin synthesis. For acute post-workout inflammation, cryotherapy responds faster. For chronic systemic inflammation that has persisted over weeks or months, the Ammortal Chamber's cumulative protocol produces deeper results.

Mental Clarity

Both produce mental clarity, again through different mechanisms. Cryotherapy delivers immediate cognitive sharpness through norepinephrine surge, a mechanism that kicks in within minutes of the session. The Ammortal Chamber delivers clearer thinking via molecular hydrogen's neuroprotective effects and the parasympathetic shift produced by breathwork and vibroacoustic therapy. Cryo is the espresso. The chamber is the full night of sleep.

Best Use Cases

Cryotherapy tends to be the better fit for acute recovery after training, athletic performance days, quick resets before demanding schedules, and clients who want a measurable three-minute return. The Ammortal Chamber tends to be the better fit for chronic fatigue, brain fog, systemic inflammation, stress management, and clients who have already tried individual recovery modalities without achieving the results they expected.

When to Book Cryotherapy First

You are recovering from a specific training session, race, or physical event within the next 24 to 48 hours.

You want immediate, sharp energy and focus before a demanding day or competition.

You have never tried cold therapy and want to experience what vasoconstriction and norepinephrine release feel like.

You want a three-minute session that fits into a packed schedule without adding recovery time.

You are planning to build a contrast therapy protocol combining heat and cold, and want to establish cold tolerance before pairing with the infrared sauna or cold plunge.

When to Book the Ammortal Chamber First

You are dealing with chronic fatigue, persistent brain fog, or stress that a single good night of sleep does not fix.

You have already tried standalone red light therapy or PEMF and want to see what those modalities do when working with four others simultaneously.

You are managing inflammation from a recurring injury or overtraining that has not fully resolved with rest or other treatments.

You want an experience that is genuinely unlike anything else you have tried, not a colder or hotter version of something familiar.

You have 25 minutes and want the most comprehensive recovery intervention currently available in the San Fernando Valley.

What About Using Both?

A significant share of regular clients at Biohack use both services. The most common protocol: cryotherapy on training days for the acute inflammatory response and sharp reset, Ammortal Chamber on recovery days or the evening before a hard session for systemic restoration. Some clients combine both in the same visit.

The biological logic is sound. Cryotherapy's vasoconstriction and inflammatory response pairs well with the Ammortal Chamber's cellular repair and antioxidant protocols. They address recovery from different angles, and the effects complement rather than cancel each other. If stacking them interests you, ask the practitioner team at Biohack about sequencing for your specific goals.

Frequently Asked Questions

Can I do cryotherapy and the Ammortal Chamber on the same day?

Yes. A common sequence is cryotherapy first, for the energizing and acute inflammatory response, followed by the Ammortal Chamber for deeper cellular recovery. Ask the practitioner team at Biohack about sequencing based on your specific goals.

Which is better for post-workout recovery, cryotherapy or the Ammortal Chamber?

Both are effective for post-workout recovery but through different mechanisms. Cryotherapy is faster and more acute, ideal for the same day as training. The Ammortal Chamber provides deeper systemic recovery and is particularly effective for cumulative soreness, chronic inflammation, and multi-system restoration. Many athletes use cryotherapy post-workout and the Ammortal Chamber on recovery days.

Which is more expensive, cryotherapy or the Ammortal Chamber?

The Ammortal Chamber 25-minute session is priced at $125, reflecting the five technologies delivered simultaneously. Cryotherapy sessions are priced lower. Both services are available under membership and package options that reduce the per-session cost.
