沖凍水涼有益還是有害？ 心臟科醫生提醒： 心血管病患者應該注意健康風險

但讀者應該注意，以上研究多針對健康人群，研究規模小、統計功效不足、亦多缺乏隨機對照試驗（Randomised controller trial), 因此從科學角度看，只能視為假定性結論，目前沒有足夠嚴謹的醫學實證支持洗冷水澡有益於心血管健康。

沖凍水涼｜注意事項：並非人人都適合沖凍水涼 1類人士應注意健康風險！

美國國家冷水安全中心（National Center for Cold Water Safety）曾撰文提醒，若突然全身浸入10至15.5°C的冷水，或可致1分鐘內有生命危險¹⁰。

亦有研究曾發現冬季游泳比賽參加者的心臟肌鈣蛋白（Troponin）水平較高，反映長時間浸泡在冷水中有機會可能導致心肌受損¹¹。

患有已知或隱性的心血管疾病人士亦可能因全身急速暴露於冷水中，出現心律失常或急性心肌缺血^12,13，可對健康構成重大風險 。
