Health benefits
Experience the benefits of cold water therapy — support recovery, boost energy, and build resilience with your LUMI ice bath on every plunge.
MENTAL CLARITY & FOCUS
Cold water immersion triggers the release of adrenaline and norepinephrine, boosting focus, mental clarity, and overall cognitive function.
ENHANCES MOOD & REDUCES STRESS
Cold exposure stimulates endorphin production, lowering cortisol levels and helping to reduce anxiety, stress, and brain fog.
STRENGTHENS THE IMMUNE SYSTEM
Cold exposure stimulates white blood cell production and reduces chronic inflammation, supporting a stronger immune response.
FASTER MUSCLE RECOVERY
Cold water therapy can help minimize muscle damage and promote faster recovery — LUMI ice baths help athletes train harder and stay at peak performance.
Yes - Where specified, our chiller units are designed to be water resistant and rated for outdoor use, ensuring reliable outdoor performance.
However, for your safety and the safety of others, make sure the chiller is plugged into an AC socket that is appropriate for outdoor use, properly grounded, has a built-in surge protector, and ideally is IP65 rated.
Always turn off the chiller before starting your cold water therapy session. Whilst most of our our chillers have an IPX rating for water resistance, it's still recommended to keep them dry at all times.
Do not immerse, splash, or spray the chiller unit with water.
Does the chiller need to be left on?
We recommend keeping your chiller on when the ice bath is not in use. This allows it to continuously filter the water, ensuring freshness.
The chiller automatically turns off once it reaches the set temperature, optimizing energy efficiency.
But remember, for safety, to always switch off the chiller unit during your ice bath session.
Is Ozone water treatment bad for the environment?
Not at all — Ozone water treatment is much more eco-friendly than using chlorine.
In our chillers, the built-in Ozone purification system releases ozone gas into the water, where it rapidly breaks down organic matter, bacteria, and microbes. Once the cleaning process is complete, the ozone naturally reverts back into pure oxygen, leaving no harmful residue behind.
How long does the Ozone last?
The Ozone generator in our chillers activates roughly once every hour for 2-5 minutes at a time. This can be adjusted higher and lower depending on requirements.
We recommend the chiller is left on at all times to keep the water moving and the Ozone active.
Can I control the chiller via a mobile app?
Yes - Where specified, our chiller units can be connected to your Wi-Fi and be controlled remotely by a iOS / Android mobile app.
How do I maintain the chiller?
Maintenance purely lies with the water and filters - regularly replacing the ice bath water, cleaning the hair filter and replacing the particle filter when you see a build up of dirt or algae.
The main circulation and priming pumps have an exceptional lifespan, and the chillers generally are designed for continuous use.
What happens if there is a fault with the chiller, and how do I tell?
In general, the only aspects that can go wrong are dirt and debris clogging up the filters and eventually passing into the internal systems. This results in poor flow, and eventually no cooling.
We have a 1 year warranty that covers any manufacturing issues.
Warnings
ALWAYS consult your doctor before using an ice bath if you have any health issues!
DO NOT USE if you are: - pregnant, have heart disease or high blood pressure, have diabetes, complications such as neuropathy or retinal damage, you wear a pacemaker, history of frostbite, have an open wound, had recent surgery, epilepsy or any other health concerns or risks.
Using an ice bath can dramatically decrease your body core temperature. The immersion in cold water constricts blood vessels and slows the flow of blood around the body, which combined with health complications, can cause your blood pressure to rise and give you a higher chance of cardiac arrest or stroke.
Possible side effects:
The most noticeable side effect of an ice bath is feeling intense cold, but other side effects of staying in an ice bath for too long are: - hypothermia, frostbite, tachycardia (fast heart beat), arrhythmias (abnormal heart beat), and anaphylactic shock.
Our recommendation:
Despite the potential side effects and warnings, using an ice bath correctly actually has many health benefits! We will always recommend you begin by spending no more than a few minutes in the ice bath, and slowly working you way up to the recommended time, never push your body beyond its limits.
