What is Cold Plunge?
A cold plunge (also known as an ice bath) is a practice where the body is briefly submerged in cold water (typically between 4–10°C) to trigger a range of physiological and mental responses.
Our Chill Tubs Lite is a professional-grade, temperature-controlled tub designed for safe, clean, and consistent cold water immersion.
Cold plunging activates the body’s natural stress response and many people report better energy, sharper focus, and a boosted sense of wellbeing following cold exposure.

Cold plunge pairs especially well with floatation tank sessions, in a similar manner to traditional contrast therapy (cold plunge and sauna). Doing a cold plunge beforehand stimulates the nervous system and boosts the release of brain chemicals (such as noradrenaline, dopamine and endorphins), helping you enter the float tank in a more grounded, alert state. The contrast between cold and warm environments enhances body awareness, deepens relaxation, and may even amplify the meditative effects of floating.
For many, this sequence results in a stronger mental reset, a more profound drop into stillness, and longer-lasting benefits from both therapies.

In the colder winter months (November - February), our tub will be heated to over 37°C for a relaxing, warm plunge experience (like a hot tub without the bubbles).
What are the benefits?

Reduced Muscle Soreness
Studies show that cold water immersion can reduce delayed-onset muscle soreness (DOMS) after intense exercise, leading to faster recovery times.
​
The likely mechanisms for this are reduced inflammation, decreased tissue temperature, and the constriction of blood vessels reducing swelling.

Improved Mental Health
Cold exposure increases noradrenaline, dopamine and endorphins, which can enhance mood and focus.
Regular cold plunging may reduce symptoms of depression and anxiety by positively affecting neurotransmitter balance and stress adaptation.

Metabolic Benefits
Cold plunging can increase brown fat activation, which burns energy to generate heat — possibly supporting metabolic health and weight regulation.

Stress Tolerance and Resilience
Repeated cold exposure acts as a hormetic stressor — a small, manageable challenge that strengthens the body’s resilience.
​
This includes improved autonomic nervous system balance, especially better parasympathetic (rest-and-digest) activation post-plunge.

Immune System Boost
Some studies show increased white blood cell count and improved immune readiness with consistent cold exposure (although more long-term human data is needed).

Circulatory Benefits
Cold plunging can improve circulation due to vascular “training” — vasoconstriction during cold exposure and vasodilation upon warming.
