TL;DR

Contrast therapy strengthens your immune system in two ways: cold exposure increases white blood cell production (your body's frontline defenders), while heat activates heat shock proteins that repair cells and prevent damage. Regular sessions can build lasting immune resilience. Book a session at Hesa Spa.

Contrast therapy boosts your immune system through two proven mechanisms: cold water immersion stimulates white blood cell production, while heat exposure activates protective heat shock proteins. Together, this combination strengthens your body's natural defences and builds resilience against illness.

Cold Exposure and White Blood Cells

When our body is exposed to cold temperatures, it responds by speeding up the metabolic rate to maintain its core temperature. This process stimulates the immune system, resulting in increased white blood cell production. These cells are your body's frontline defenders, fighting off foreign invaders like bacteria and viruses.

Our cold plunge pool, kept at a bracing 7--10 degrees Celsius, provides the ideal environment for triggering this beneficial cold response.

Heat Shock Proteins and Immune Response

Heat exposure activates heat shock proteins. These proteins play a critical role in the body's immune response, repairing damaged proteins and even preventing cellular damage. When you step into a hot plunge pool or steam room, your body begins producing these protective proteins immediately.
