Healthy Horizon · Lisbon
Three structured monthly programmes. Each built around a single biological objective. Designed for those who want measurable results, not just access.
A treatment is a single session. A protocol is a structured sequence of treatments, repeated across a membership month, designed to produce a specific measurable outcome.
Each protocol is built around a clinical logic. The treatments within it are not arbitrary. They are selected because they create complementary signals in the body, and because their effects compound when applied consistently.
Protocols require an active Horizon Circle membership (111€/month). Sessions expire at the end of each month. Cancel anytime.
Protocol 01
Systemic Decompression for Anxiety & Better Sleep
Primary indications
Physiological goal
To support a shift from chronic sympathetic activation toward a calmer, more regulated baseline by increasing parasympathetic (vagal) activity and reducing excessive sympathetic drive. The protocol uses sensory modulation and gentle neuromodulation to help the nervous system access restorative states more easily.
How the protocol works
You are exhausted. But you cannot switch off. That is not a mindset problem. It is a biology problem.
When your nervous system is locked in chronic stress mode, no amount of rest fixes it. The body needs structured, repeated input to learn how to regulate again. That is what this protocol does.
Each session combines sensory deprivation, vagal nerve stimulation, vibroacoustic therapy, and neural entrainment to progressively shift your autonomic baseline. Less anxiety. Deeper sleep. Faster recovery from stress.
Two visit types per week. One removes all stimulation so your nervous system can decompress. The other trains it to stay calm even under input. Together, they rebuild your capacity to regulate.
Evidence notes
taVNS has been associated with increased heart rate variability (HRV) and reduced perceived stress in some clinical populations. Effect sizes vary. Flotation-REST studies report reductions in anxiety, blood pressure, and stress markers in many participants. Vibroacoustic therapy evidence supports reduced pain and tension. Research across these modalities is ongoing.

Protocol 02
Cellular Energy Renewal for Sustained Performance
Primary indications
Physiological goal
To support mitochondrial function and biogenesis through repeated, controlled stimuli that promote cellular energy efficiency. Mitochondria are the primary sites of ATP production in the body; their number, density, and efficiency decline with age and chronic stress. This protocol uses oxygen training, photobiomodulation, molecular antioxidant support, and respiratory conditioning to encourage the body's own adaptive responses at the cellular level.
How the protocol works
IHHT (Intermittent Hypoxic-Hyperoxic Training) is the cornerstone modality. Alternating cycles of reduced and enriched oxygen signal the cells to adapt, upregulating mitochondrial biogenesis pathways. Red Light Therapy at higher frequency supports mitochondrial efficiency between IHHT sessions by interacting with cytochrome c oxidase in the electron transport chain. Molecular Hydrogen Therapy neutralises excess reactive oxygen species, reducing the oxidative burden on recovering cells. AirFit Respiratory Training conditions the respiratory muscles and improves oxygen uptake efficiency. Sauna & Cold Plunge completes the protocol by activating heat shock proteins and improving cardiovascular resilience.
Evidence notes
IHHT has been associated in some studies with improvements in mitochondrial density, VO2 max, and cardiovascular efficiency, particularly in sedentary and clinical populations. Regular sessions over several weeks are generally required for measurable adaptation. Photobiomodulation evidence for mitochondrial support is growing; optimal dosing remains an area of active research. Molecular hydrogen research on inflammation balance and oxidative stress is promising but still developing.

Protocol 03
Tissue Repair, Joint Unloading and Inflammatory Support
Primary indications
Physiological goal
To create a biological environment that supports tissue repair and comfort by improving oxygen availability in areas with compromised circulation, reducing gravitational load on joints and the spine, supporting fluid movement and edema management, and providing gentle neuromodulation and anti-inflammatory support. The protocol addresses recovery from both a biochemical perspective (oxygenation, oxidative stress, inflammation) and a biomechanical perspective (load reduction, muscle tension, fluid dynamics).
How the protocol works
Your body is asking for repair. Not more stimulus. Not more performance. Repair.
Whether recovering from injury, managing chronic inflammation, or coming off a period of sustained overload, this protocol creates the biological conditions for tissue recovery to happen faster and more completely. Pressurised oxygen, gravitational unloading, oxidative stress reduction, and targeted circulatory work address recovery from every angle.
Two visit types per week. One concentrates on oxygenation and cellular repair at tissue level. The other targets structural decompression, tension release, and pain modulation. Together, they rebuild what sustained output breaks down.
Evidence notes
Research suggests hyperbaric oxygen can support wound healing, reduce edema, and influence inflammatory processes in certain indications. The mild pressures used here (approx. 1.3–1.5 ATA) are distinct from clinical hyperbaric protocols used at higher pressures for serious medical conditions. Flotation-REST studies report reduced muscle tension and lower pain scores. This protocol is designed as an adjunct to, not a replacement for, standard medical and rehabilitative care.

The protocols described on this page are evidence-informed wellness programmes, not medical treatments. They are designed as adjuncts to healthy living, not replacements for professional medical, psychological, or rehabilitative care. If you have a medical condition, please consult your physician before beginning any protocol. All claims are based on available scientific literature; individual results vary.
