Safety & Contraindications

Hyperbaric oxygen therapy (HBOT) is not suitable for everyone. You should avoid sessions if you currently have:

• Untreated pneumothorax (collapsed lung)
• Severe chronic obstructive pulmonary disease (COPD)
• Certain types of lung disease affecting air trapping
• Recent ear surgery or unresolved ear injury
• Pregnancy (unless medically supervised and cleared)
• Severe sinus infections or blocked Eustachian tubes
• Active chest infections
• Uncontrolled high fever
• Perforated ear drums

Hyperbaric oxygen therapy should only be undertaken following clearance from your GP or relevant specialist if any of the above apply.

GP guidance is recommended before booking if you:

• Have severe asthma or another significant respiratory condition
• Experience frequent ear pressure issues when flying
• Have had recent dental surgery
• Have a history of seizures
• Are undergoing chemotherapy or taking medication known to affect oxygen sensitivity

HBOT involves sitting inside a gently pressurised chamber while breathing concentrated oxygen. Pressure levels and oxygen exposure are carefully controlled; however, pre-existing respiratory, ear or neurological conditions must be reviewed beforehand.

Yes – when delivered in a supervised environment with proper screening.

At Brysk, sessions are structured and monitored throughout. Pressure levels are controlled, and staff guide you through equalising ear pressure during the pressurisation phase.

Suitability is reviewed before entry, and sessions are designed to remain calm, gradual, and controlled rather than intense.

In most cases, yes. However, if you experience ongoing ear pressure discomfort following a session, you should wait until symptoms resolve before flying. If you have a history of ear or sinus issues, obtain medical advice prior to booking.

Mild ear pressure – similar to what you may experience during a flight – can occur as the chamber pressurises.

Staff guide you through simple equalisation techniques, and pressurisation is gradual. If discomfort persists, the session can be paused or adjusted immediately.

Your comfort and safety are prioritised at all times.

Whole body red light therapy is generally well tolerated. However, sessions may not be suitable if you:

• Have a diagnosed photosensitivity disorder
• Are taking medication that increases light sensitivity
• Have active skin infections or open wounds
• Have recently undergone laser-based skin procedures
• Have a history of light-triggered seizures

If you are unsure whether red light therapy is appropriate for you, obtain medical guidance before attending.

Medical advice is recommended if you:

• Are taking antibiotics, retinoids, or other medication known to increase light sensitivity
• Have a history of epilepsy or neurological conditions
• Have recently had cosmetic or dermatological procedures
• Are pregnant and unsure about suitability

Red light therapy uses specific wavelengths of light delivered in a controlled environment. While the exposure is non-invasive, suitability should always be considered in the context of your overall health.

Yes – when delivered in a supervised setting with clear guidance.

At Brysk, sessions are structured and monitored. Protective eyewear is provided, and exposure duration is controlled to ensure sessions remain comfortable and appropriate.

Red light therapy is non-invasive and does not involve heat stress or pressure changes, making it suitable for many people following appropriate screening.

Red light therapy is generally well tolerated. Mild temporary redness or warmth may occur. When used appropriately and with eye protection (when required), significant adverse reactions are uncommon.

In most cases, yes.

Whole body red light is commonly paired with cryotherapy, hyperbaric oxygen, compression, or lymphatic drainage depending on your goals. If you are unsure about sequencing or suitability, the Brysk team can guide you before booking.

Localised cryotherapy may not be suitable if you:

• Have severe Raynaud’s syndrome
• Have cold allergies or cold-induced urticaria
• Have impaired circulation in the targeted area
• Have open wounds or unhealed skin in the treatment area
• Have active skin infections
• Have a history of deep vein thrombosis affecting the targeted limb

Medical clearance should be obtained before booking if any of the above apply.

Medical guidance is recommended if you:

• Have diabetes with reduced sensation in the affected area
• Have nerve damage or neuropathy
• Are taking medication that affects circulation
• Have recently undergone surgery in the area you wish to treat

Localised cryotherapy involves controlled cold air directed at a specific area of the body. While exposure is targeted and brief, reduced sensation or circulation can increase risk if not screened properly.

Yes – when delivered in a supervised setting.

At Brysk, localised cryotherapy is applied by trained staff using controlled equipment. Exposure duration is guided carefully, and the skin is monitored throughout.

Sessions are designed to remain controlled, targeted, and comfortable.

Localised cryotherapy cools a defined area rather than triggering a systemic cold response.

Because exposure is targeted, systemic stress is reduced compared to whole body cryotherapy. However, suitability screening remains important – particularly where circulation or nerve sensitivity may be affected.

Compression boots may not be suitable if you currently have:

• Deep vein thrombosis (DVT) or a history of blood clots
• Severe peripheral vascular disease
• Acute skin infections affecting the legs
• Uncontrolled heart failure
• Recent lower limb fractures or unstable injuries

Compression sessions should only proceed following medical clearance if any of the above apply.

GP consultation is recommended if you:

• Have diabetes with reduced sensation in the legs
• Experience unexplained swelling in one limb
• Have recently undergone surgery
• Have known circulatory or cardiovascular conditions

Compression therapy works by rhythmically inflating chambers around the legs to support circulation. While the pressure is controlled and adjustable, underlying vascular conditions should always be reviewed first.

Yes – when used appropriately.

At Brysk, sessions are structured and pressure levels are selected based on comfort and suitability. You remain seated and supervised throughout.

Compression is designed to feel firm but comfortable. If anything feels unusual or uncomfortable, pressure can be adjusted immediately.

No. When used appropriately in individuals without active clotting disorders, compression boots are designed to support venous return rather than promote clot formation. However, they should not be used if you have an existing deep vein thrombosis (DVT) unless medically cleared.

In most cases, yes.

Compression is often paired with cryotherapy, red light, or lymphatic drainage during training blocks or busy periods. If you are unsure about sequencing or suitability, the team can advise before booking.

Lymphatic drainage may not be suitable if you currently have:

• Active infections or fever
• Untreated or active cancer
• Severe heart failure
• Acute kidney disease
• Deep vein thrombosis (DVT)
• Unexplained swelling or fluid retention

If any of the above apply, clearance from a healthcare professional is required before booking.

Professional medical advice is recommended if you:

• Have ongoing medical treatment affecting fluid balance
• Experience persistent swelling
• Have recently undergone surgery
• Have a diagnosed lymphatic disorder

Lymphatic drainage supports natural lymphatic fluid movement within the body. While sessions are gentle and low-impact, certain medical conditions require clearance before proceeding.

Yes – when suitability has been reviewed.

At Brysk, sessions are structured, supervised, and designed to feel calm and low-intensity. Pressure levels are controlled and adjustable.

If you are unsure about suitability, the Brysk team can guide you before booking.

In most cases, yes.

Lymphatic drainage is often paired with cryotherapy, compression, or red light therapy depending on individual goals and workload. Sequencing can be adjusted to fit comfortably around your routine.
