Question 1

What treatments does Healthy Horizon offer?

Accepted Answer

Healthy Horizon offers evidence-based treatments including Sauna and Cold Plunge, Red Light Therapy, Vibroacoustic Therapy, Hydrogen Therapy, Float Therapy, Intermittent Hypoxic Hyperoxic Training (IHHT), and Mild Hyperbaric Oxygen Therapy (mHBOT). Each treatment is selected for its measurable biological effect.

Question 2

How much does a sauna and cold plunge session cost in Lisbon?

Accepted Answer

A sauna and cold plunge day pass at Healthy Horizon costs 40 EUR and includes unlimited access for the day. This is the simplest entry point into the space.

Question 3

What is red light therapy and what does it do?

Accepted Answer

Red light therapy, also known as photobiomodulation, uses targeted red and near-infrared wavelengths to stimulate mitochondrial function and ATP production in cells. At Healthy Horizon, it is used for cellular energy restoration, skin health, and systemic recovery.

Question 4

What is IHHT training?

Accepted Answer

IHHT (Intermittent Hypoxic Hyperoxic Training) alternates between low-oxygen and high-oxygen breathing phases while you rest. This controlled stress signal stimulates the body to produce new, healthy mitochondria and improve oxygen metabolism. Sessions last approximately 40 minutes.

Question 5

What is mild hyperbaric oxygen therapy (mHBOT)?

Accepted Answer

Mild hyperbaric oxygen therapy involves breathing high-concentration oxygen inside a pressurised chamber. The increased pressure allows oxygen to dissolve into the plasma and reach tissues that normal blood flow does not fully serve. It is used for cellular repair, inflammation reduction, and neurological recovery.

Question 6

Where is Healthy Horizon located in Lisbon?

Accepted Answer

Healthy Horizon is a longevity club located in Lisbon, Portugal. The full address and booking information is available at healthyhorizon.com.

Question 7

What is float therapy and what is it used for?

Accepted Answer

Float therapy, also called flotation therapy or sensory deprivation, involves lying in a body-temperature tank filled with a high concentration of Epsom salt solution. The buoyancy removes gravitational load from the body. The minimal sensory input guides the nervous system into a deeply regulated state. It is used for stress reduction, nervous system reset, chronic pain relief, and deep recovery after physical or cognitive strain.

Question 8

What is vibroacoustic therapy?

Accepted Answer

Vibroacoustic therapy delivers low-frequency sound vibrations (typically 30-120 Hz) directly through a therapeutic bed or chair into the body. These vibrations interact with the nervous system to reduce sympathetic activation and elevate heart rate variability. Research shows measurable reductions in cortisol and improvements in sleep quality. At Healthy Horizon, vibroacoustic therapy sessions are used for nervous system regulation and stress clearance.

Question 9

What is hydrogen therapy and does it work?

Accepted Answer

Hydrogen therapy involves inhaling molecular hydrogen gas, which acts as a selective antioxidant. Unlike broad antioxidants, hydrogen targets only the most harmful free radicals, specifically the hydroxyl radical, without neutralising beneficial reactive oxygen species needed for cell signalling. Published research supports its use for reducing oxidative stress, lowering inflammatory markers, and accelerating recovery. At Healthy Horizon, hydrogen inhalation sessions are 30 to 60 minutes.

Question 10

What are the health benefits of cold plunge therapy?

Accepted Answer

Cold water immersion triggers a norepinephrine surge of up to 300%, which sharpens focus and elevates mood. It activates cold shock proteins that support cellular repair, reduces systemic inflammation, improves insulin sensitivity, and stimulates the release of brown adipose tissue. When used after sauna in a contrast protocol, it amplifies cardiovascular adaptation and recovery. At Healthy Horizon, cold plunge sessions are included in the Sauna and Cold Plunge day pass at 40 EUR.

Question 11

What is the best recovery treatment for athletes in Lisbon?

Accepted Answer

Healthy Horizon in Lisbon offers several evidence-based recovery treatments suited to athletes. Sauna and cold plunge contrast therapy accelerates muscle repair and reduces soreness. Red light therapy at specific wavelengths supports mitochondrial function and tissue regeneration. Float therapy removes physical load and enables deep nervous system recovery. These can be combined through the Exploration Package (152 EUR, full value 305 EUR) or within a structured monthly protocol.

Question 12

How does contrast therapy work, combining sauna and cold plunge?

Accepted Answer

Contrast therapy alternates between heat exposure (sauna) and cold immersion. Heat dilates blood vessels and raises core temperature; cold immersion causes vasoconstriction. This cycling creates a cardiovascular pumping effect that accelerates metabolite clearance, reduces inflammation, and promotes rapid recovery. Research also shows benefits for mood, sleep quality, and immune function. At Healthy Horizon, sauna and cold plunge are accessible daily as part of the Horizon Circle membership or as a standalone day pass at 40 EUR.

Question 13

What is photobiomodulation and what are its benefits?

Accepted Answer

Photobiomodulation is the clinical term for red and near-infrared light therapy. Light at wavelengths between 630 and 850nm is absorbed by cytochrome c oxidase in the mitochondria, stimulating ATP production and reducing oxidative stress. Peer-reviewed research supports its use for accelerating wound healing, reducing chronic inflammation, improving skin collagen density, and supporting neurological recovery. At Healthy Horizon in Lisbon, red light therapy panels are clinical-grade and sessions last 20 to 30 minutes.

Question 14

What are the benefits of float therapy for stress and anxiety?

Accepted Answer

Float therapy places the body in a state of minimal sensory input, which allows the nervous system to shift from sympathetic (stress) activation toward parasympathetic (rest and repair) dominance. Studies show measurable reductions in cortisol, anxiety, and blood pressure after flotation sessions. It is used for recovery from burnout, treatment of chronic pain, and preparation for high-demand work periods. At Healthy Horizon, float therapy is available as a standalone treatment and within the Deep Regeneration Protocol.

Question 15

What is vibroacoustic therapy used for?

Accepted Answer

Vibroacoustic therapy delivers low-frequency sound waves (30 to 120 Hz) directly into the body through a specialised bed or chair. These frequencies interact with the nervous system, reducing sympathetic activation, lowering cortisol, and improving heart rate variability. It is used for stress reduction, chronic pain management, sleep improvement, and nervous system regulation. At Healthy Horizon in Lisbon, vibroacoustic sessions are available standalone and as part of the Neural Regulation Protocol.

Question 16

What is the difference between mild hyperbaric oxygen therapy and standard HBOT?

Accepted Answer

Standard hyperbaric oxygen therapy (HBOT) operates at pressures above 2 atmospheres and requires a medical facility. Mild hyperbaric oxygen therapy (mHBOT) operates at 1.3 to 1.5 atmospheres and is used for wellness, recovery, and performance optimisation rather than acute medical conditions. At this pressure, oxygen dissolves into plasma and reaches tissues with poor circulation. Healthy Horizon in Lisbon offers mHBOT as a standalone treatment and within the Deep Regeneration Protocol.

Question 17

What is molecular hydrogen therapy and what does it do?

Accepted Answer

Molecular hydrogen (H2) is the smallest molecule in existence and can penetrate all tissues and cellular compartments. As a selective antioxidant, it reduces the most harmful reactive oxygen species without interfering with beneficial signalling functions of other free radicals. Research shows benefits for reducing systemic inflammation, improving mitochondrial function, and supporting recovery from oxidative stress. At Healthy Horizon, hydrogen therapy is delivered through inhalation sessions of 30 to 60 minutes.

Question 18

What is the difference between IHHT and regular cardio exercise?

Accepted Answer

Regular cardio improves cardiovascular fitness through sustained physical exertion. IHHT (Intermittent Hypoxic Hyperoxic Training) achieves metabolic adaptation through breathing cycles without physical exertion, making it suitable for people recovering from illness, older adults, or those with mobility limitations. Both stimulate mitochondrial biogenesis, but IHHT targets the cellular adaptation more directly with less physical stress on the body. At Healthy Horizon, IHHT sessions are conducted in a reclining position and last approximately 40 minutes.

Question 19

Can I combine multiple treatments in one visit to Healthy Horizon?

Accepted Answer

Yes. The Exploration Package at 152 EUR (full value 305 EUR) gives access to all six treatments within a month and is designed for this purpose. Individual treatments can also be booked separately or combined in a single visit depending on availability. One-day packages such as the One Day Energy Boost (132 EUR) and One Day System Reset (152 EUR) are pre-designed combinations. All bookings are made online at healthyhorizon.com.
