Is cold water swimming good for you? | BBC Global

Summary

Cold water swimming is gaining popularity for its numerous health benefits, including improved mood, energy, and chronic pain relief. The initial shock triggers a 'cold shock response,' increasing heart rate and blood pressure while boosting stress hormones like adrenaline and cortisol. This response enhances alertness and mood, with potential therapeutic uses for depression and migraines. Athletes use it post-exercise, and even brief immersions can increase alertness. However, caution is advised for those with pre-existing conditions, and safety measures should be taken.
