The Science of Thermal Comfort

Cryotherapy, or cold therapy, involves exposing the body to low temperatures for a short duration. This practice, used for centuries, is the subject of numerous scientific studies. The information presented here is for informational purposes only and does not constitute medical advice. Effects may vary among individuals.

The following effects are observed in some scientific studies. They may vary among individuals and do not constitute guaranteed results.

• Muscle recovery: Cold can help reduce inflammation and support recovery after physical exertion.
• Immune system: Regular cold exposure may support certain immune functions according to some studies.
• Blood circulation: Thermal shock can promote circulation and tissue oxygenation.
• Mental health: The practice can promote the release of endorphins and help reduce stress.
• Sleep: Post-bath thermal regulation can promote better quality sleep.

During immersion in cold water, the body reacts by activating several defense mechanisms: vasoconstriction of blood vessels, release of well-being hormones, and activation of the sympathetic nervous system. These chain reactions can produce beneficial effects on the body, although results vary among individuals.

For beginners, start with immersions of 2 to 3 minutes at 15°C, then gradually increase the duration and decrease the temperature according to your tolerance. Some practitioners aim for 3 to 5 sessions per week. These indications are for guidance only. In case of a particular medical condition, it is imperative to consult a health professional before starting.

Ambient temperature plays a key role in our physical and mental state. An environment that is too hot increases fatigue, reduces concentration, and disrupts sleep. Conversely, a cool and controlled temperature promotes alertness, comfort, and restful sleep. YVRAK fans and air conditioners are selected to create this optimal environment.

• Better sleep: Sleep science recommends a bedroom temperature between 16°C and 19°C for optimal rest.
• Increased concentration: A cool environment reduces cognitive fatigue and improves intellectual performance.
• Physical comfort: Coolness reduces excessive sweating and improves general comfort, especially in summer.
• Mood & well-being: A thermally comfortable environment reduces irritability and promotes a positive state of mind.

Both approaches are complementary and meet different needs:

• Ice bath — Ideal for intensive sports recovery, pushing personal limits, and profound physiological effects. Requires prior medical advice.
• Fan / Air Conditioner — Ideal for daily comfort, sleep, concentration, and ambient well-being. Accessible to everyone, without any particular constraints.

At YVRAK, we believe that everyone deserves to find their own thermal balance.
