What are the benefits of cold-water immersion for post-exercise recovery after age 50?

 title: 'Effects of cold-water immersion on health and wellbeing: A systematic review and meta-analysis'

Information on the benefits of cold-water immersion (CWI) for post-exercise recovery specifically after age 50 is not available in the provided texts[4].

However, for healthy adults, CWI can significantly reduce delayed-onset muscle soreness (DOMS) immediately after exercise[1][2][4][6]. Regarding inflammation, findings are mixed: some studies show no effect on markers like CRP and IL-6[1][2], while others report an immediate increase in inflammation markers, which may reflect metabolic responses[4]. CWI can acutely increase the secretion of cortisol and norepinephrine[4]. The texts mention 'potential risks of CWI' and the need for more research on safety, but do not specify cardiovascular conditions as contraindications[4].
