Why cold therapy works
Cold water immersion sets off a wave of physiological responses. Blood vessels constrict, reducing inflammation and swelling in muscles and joints. Even after you step out, the benefits continue — circulation surges, flushing metabolic waste, delivering oxygen-rich blood to tissue, and accelerating repair.
Consistent exposure also triggers norepinephrine, a hormone tied to mood, focus, and pain tolerance. Over time the benefits compound: faster recovery, better sleep, lower anxiety, and a measurable boost in daily energy.
