repeated cold-water immersion raises lymphocyte and white blood cell counts in healthy adults
Long-term cold-water immersion (3 times a week for 6 weeks) in healthy males increased lymphocyte numbers, and habitual winter swimmers had higher white blood cell counts than non-swimmers.
What this means for you
White blood cells and lymphocytes are your body's frontline immune defenders. When their numbers rise with regular cold exposure, your immune system has more resources to identify and respond to everyday threats — which many people notice as fewer sick days and a general sense of resilience.
