Frequently asked questions

Hyperbaric Oxygen Chambers

Hyperbaric oxygen chambers come in different types, each designed to serve specific therapeutic needs and environments whether in the comfort of your home, a wellness spa, physiotherapy clinic, hospital, or sports recovery center.

At Zerava, we offer one of the most comprehensive ranges of hyperbaric chamber systems.

What is Hyperbaric Oxygen Therapy (HBOT)?

HBOT involves placing an individual inside a pressurized chamber while breathing oxygen. Increasing atmospheric pressure enhances oxygen absorption in the blood plasma, helping oxygen reach tissues with restricted blood flow.

Research suggests HBOT may contribute to various physiological responses, including:

Supporting natural recovery processes (muscle repair & recovery)
Enhancing circulation and oxygenation
Modulating inflammatory responses
Triggering the Hyperoxic-Hypoxic Paradox (a process linked to cellular resilience and adaptation)

How Does HBOT Work?

Studies indicate HBOT supports the body through multiple mechanisms:

Hyperoxygenation – Increases oxygen levels in tissues, supporting repair
Vasoconstriction – May reduce localized swelling
Angiogenesis – Promotes new blood vessel growth
Fibroblast activity & collagen production – Supports tissue repair and elasticity
Oxidative stress modulation – Influences antioxidant pathways

Common Applications of HBOT

While HBOT is FDA-approved for 15 specific medical conditions (including decompression sickness, carbon monoxide poisoning, radiation injury, and diabetic foot ulcers), it is also gaining attention for wellness, sports, and longevity.

Research suggests potential benefits in areas such as:

Neurological conditions: stroke, TBI, cerebral palsy, Alzheimer’s, autism spectrum disorder (ASD)
Sports recovery & performance: accelerated muscle recovery, reduced fatigue
Chronic conditions: non-healing wounds, chronic pain, fibromyalgia
Mental health: depression, anxiety, PTSD
Longevity & vitality: anti-aging, cellular health, improved energy
Cognitive function: enhanced focus, memory, and clarity

HBOT & Anti-Aging Research

Scientific studies suggest HBOT may influence several factors linked to aging and cellular health:

Telomere length – Studies indicate HBOT may extend telomeres by up to 20%, associated with cellular longevity.
Stem cell activation – May support tissue regeneration.
Collagen production – Enhances skin elasticity, reducing wrinkles and sagging.
Neuroplasticity – Supports new neuron growth, improved cognition, and reduced inflammation.

These findings make HBOT a promising option in the field of healthy aging and vitality.

Possible Risks & Side Effects

HBOT is generally well tolerated. Some individuals may experience temporary side effects such as:

Ear pressure discomfort (similar to airplane travel; relieved by swallowing or equalizing pressure)
Sinus congestion or discomfort
Temporary nearsightedness (myopia) – usually resolves post-therapy
Fatigue – some users report tiredness after sessions

These effects are typically mild and resolve shortly after treatment.

Safety Guidelines & Contraindications

HBOT is generally safe and well tolerated by most people. However, always check with your healthcare provider before starting HBOT.

Absolute Contraindications

Untreated pneumothorax – Must be treated before HBOT. Pressurization can expand trapped air, leading to life-threatening tension pneumothorax.

Pre-session chest imaging is mandatory.
Inability to equalize ear pressure – Conditions such as severe congestion, Eustachian tube dysfunction, or anatomical abnormalities can cause ear barotrauma.

Relative Contraindications

These conditions may not exclude HBOT but require medical precautions:

Use of certain chemotherapy agents (Bleomycin, Doxorubicin, Cisplatin)
Recent or current use of Sulfamylon (Mafenide Acetate)
Upper respiratory infections or sinus congestion
Claustrophobia
COPD with CO₂ retention
Seizure disorders
Pregnancy (unless life-threatening indication)
Uncontrolled hypertension
Implanted devices (pacemakers, defibrillators, insulin pumps — must be checked for compatibility)
History of pulmonary edema or severe heart failure (EF <25%)
Diabetes mellitus (risk of hypoglycemia; monitor glucose levels)
Recent middle ear or sinus surgery
Recent chest surgery or thoracic trauma (within one week)
Untreated glaucoma
Other conditions requiring close monitoring as advised by a physician

⚠️ Individuals should consult a qualified healthcare professional to ensure HBOT is safe and appropriate for their personal health situation.

Zerava: Discover the Life-Changing Benefits of Massage Chairs

At Zerava, we believe wellness starts with rest, recovery, and rejuvenation — and that’s exactly what our massage chairs are designed to deliver. More than just a luxury, massage chairs offer a wide range of health-enhancing benefits that support both the body and mind.

Melt Away Stress, Instantly

Unwind effortlessly as your massage chair helps activate your body’s natural relaxation response. Just 10 minutes of use can lower stress levels and boost your mood, thanks to the release of endorphins — your body’s own “feel-good” chemicals. A study from the University of Konstanz in Germany found even short sessions help reset the nervous system and reduce cortisol, the stress hormone.

Soothe Tense Muscles and Aches

Built-in massage techniques like kneading, tapping, and rolling target stubborn tension in your shoulders, back, and legs. Whether you’re recovering from a workout or a long day at work, our chairs deliver relief exactly where you need it.

Support Better Posture

Consistent use can help correct muscular imbalances and loosen tight areas that contribute to poor posture. Over time, users often notice improved spinal alignment and reduced back strain.

Boost Circulation and Recovery

Massage therapy promotes healthy blood flow, which supports faster healing, better oxygen delivery, and improved muscle recovery. It’s a gentle yet powerful way to revitalize your body from within.

Effective Pain Relief

Massage chairs can aid in managing chronic pain conditions such as arthritis, back pain, and fibromyalgia. Research shows that massage therapy plays a supportive role in easing physical discomfort and also assists in managing emotional challenges like anxiety and depression — making it a powerful tool for overall wellness.

Improve Flexibility and Mobility

With stretching functions that simulate a therapist’s touch, our chairs help increase your range of motion and keep your joints supple. It's like daily mobility training, right in your living room.

Sleep Deeper, Wake Refreshed

Struggling with sleep? Massage chairs calm both the body and the mind, setting the stage for more restorative, uninterrupted rest. Many users report falling asleep faster and feeling more energized in the morning.

Natural Mood Boost

Regular sessions stimulate the release of serotonin, dopamine, and endorphins — the trio responsible for feelings of happiness, clarity, and calm. At the same time, massage lowers stress-inducing hormones like cortisol, helping to ease emotional fatigue and burnout.

Strengthen Immune Health

A more relaxed body is a stronger one. Lower stress and better circulation contribute to improved immune response, helping your body stay resilient against illness.

Feel Energized

Need a natural pick-me-up? A 15-minute massage can revive your energy and sharpen your focus — perfect for powering through a busy day without caffeine.

Recognized Therapy, Not Just a Luxury

A Harvard Medical School report confirmed that massage is now accepted as a valid form of pain therapy. It works by activating sensory pathways that help “close the pain gate” in the nervous system, reducing the intensity of discomfort signals.

Wellness for Everyone

According to research from the University of Illinois at Chicago, even people who don’t exercise regularly can benefit from massage. Participants experienced improved vascular health and circulation, proving massage is a great wellness tool for all lifestyles.

At Zerava, we’re proud to offer massage chairs that do more than relax — they renew. Designed to elevate your well-being, each chair is a long-term investment in your health, comfort, and peace
