The Impact of Water Temperature on Health: Cold vs. Warm
Swimming in cold water may have antidepressant effects, as it stimulates the release of stress hormones, endorphins, and dopamine. Preliminary evidence suggests that swimming in cold water can reduce depressed mood and improve mental health. However, the observed benefits may also be attributed to socializing with others while swimming. Cold water exposure can have arousing and stimulating effects, increasing substances involved in regulating mood. It is not necessary to take polar plunges to experience the benefits; even cool showers can have similar effects. However, swimming in cold water is not without risks, including potential cardiac arrhythmias and hypothermia.
