The Science of Cold Therapy (Cryotherapy)

Cold exposure has been studied for decades for its effects on the skin, circulation, and the nervous system. While ChillOra is a simple home ritual, it draws on established physiological responses.

Reduced Swelling & Puffiness

Cold triggers vasoconstriction — a narrowing of blood vessels. Research shows that cooling the skin between 10–15°C can help reduce swelling and fluid accumulation under the eyes.

Study reference: Bleakley et al., The American Journal of Sports Medicine (2012).

Improved Circulation (Reactive Hyperaemia)

After the initial cooling, the body increases local blood flow. This “rebound” circulation is associated with temporary brightness and a healthy-looking glow.

Study reference: Algafly & George, Archives of Physical Medicine and Rehabilitation (2007).

Skin-Barrier Support

Cold can momentarily tighten the surface of the skin and reduce the appearance of pores, giving a clearer, fresher look.

Nervous System Calm

Cold exposure activates the trigeminal nerve and signals the parasympathetic system — the “reset” mechanism that supports calmness and clarity.

Why Oil + Ice Works So Well Together

Your ritual pairs controlled cold with two plant-based oils known for their skin-compatible chemistry.

Jojoba Oil — The Skin-Mimicking Ester

Jojoba is structurally similar to human sebum. Studies show it can support the skin barrier, reduce transepidermal water loss (TEWL), and enhance moisture retention.

Study reference: Pazyar et al., Journal of Dermatological Science (2013).

Castor Oil — Rich in Ricinoleic Acid

Castor oil’s unique fatty acid profile has been studied for softening the outer skin layers, helping maintain moisture, and supporting the natural lipid barrier.

Study reference: Ogunlesi et al., Journal of Medicinal Plants Research (2009).

The ChillOra ritual blends Nordic-inspired cold immersion, certified organic plant oils, and a calming daily self-care moment.

Science explains the mechanism. Nature provides the experience. You create the ritual.
