What is BUZZ FITNESS UND GESUNDHEIT?

Premium Fitness und Gesundheits Zentrum - Longevity-Training, Kältekammer-Regeneration und personalisiertes Coaching für die Generation

Does body temperature really drop to –110°C?

No. –110°C is the air temperature in the chamber. Your core body temperature stays stable – only the skin cools.

Why only 2–3 minutes?

The effect cascade builds up in those minutes. Staying longer brings no advantage and can overload the body.

What happens to the mitochondria?

Cold can stimulate the mitochondria. No blanket claim can be made.

Does the effect last long?

Endorphin and noradrenaline levels stay elevated for some hours. With regular use the effect builds steadily.

Cryo chamber –110°C: What happens in the body?

Three minutes at –110°C are no empty trick – a whole cascade runs in the body during that time. Vessels react, messenger substances are released, metabolism switches. What happens in these minutes and the hours after, you read here – without exaggerated promises, but understandable.

*BUZZ is not a medical center and offers no medical advice. If you have health concerns, please clarify use of the cryo chamber beforehand with your doctor.

Cryo chamber –110°C: What happens in the body?

Seconds 0–30: vasoconstriction

The cold stimulus hits the skin immediately. The autonomic nervous system sounds the alarm, the blood vessels at the skin surface and in the extremities constrict – blood is directed centrally to the inner organs. This protects body temperature, the core stays stable.

At the same time the body releases endorphins and noradrenaline – a mild stress that sharpens alertness. You're now wide awake, focused, in the moment.

Minute 1–3: metabolism and hormones

In the second minute, the body may release increased messenger substances that can positively influence inflammatory processes. The body switches to a higher level of energy consumption, the mitochondria are stimulated – the basis for the energy effect afterwards.

Important: at –110°C the skin cooling is fast, but the body core stays stable. Otherwise the session would be dangerous. That balance is one reason 3 minutes are common, but longer isn't recommended.

After the session: vasodilation and recovery

As soon as you leave the chamber, the vessels widen again, blood flow returns to the periphery – hands, feet, skin get perfused, the clear tingling noticeable. Oxygen-rich blood in the periphery is a pillar of recovery after sport.

Hormonally, the post-phase can be noticeable for many: noradrenaline and endorphins may stay elevated for some hours. How sleep and mood respond is individual.

Who is this suitable for?

Interested in the biological effects
Athletes who want to understand recovery
Biohackers and performance-seekers
People with inflammation questions
Skeptics checking efficacy
Returning customers who want more background

Your start in 3 steps

Stimulus in the chamber

3 minutes at up to –110°C, body reacts with vasoconstriction and hormone release.

Warm up & perfusion

Afterwards vessels widen, oxygen reaches the periphery – the tingling arises.

Post-phase & recovery

Hours later: clearer mood, more energy, often calmer sleep.
