Tóm tắt

Bơi lội trong nước mở (OWS), bao gồm cả bơi tự nhiên như bơi sông và bơi thi đấu, đang trở thành một sở thích ngày càng phổ biến cũng như là một phần của các sự kiện như triathlon. Hiện tại, có rất ít bằng chứng để xác định giới hạn nhiệt độ nước cao và thấp. Hơn nữa, do các yếu tố như sự thích nghi, điều này làm tách biệt cảm giác nhiệt độ và sự thoải mái khỏi trạng thái nhiệt, vì vậy cá nhân không thể tự mình giám sát tình trạng thể chất trong quá trình bơi. Đã có trường hợp tử vong xảy ra trong các sự kiện OWS; những trường hợp này không chỉ liên quan đến phản ứng nhiệt mà còn do các vấn đề về tim mạch. Bài viết này, là một phần trong loạt bài về 'Di chuyển trong môi trường khắc nghiệt', sẽ tóm tắt những hiểu biết hiện tại về những chủ đề liên quan đến OWS. Các hướng dẫn được đưa ra cho việc tổ chức các sự kiện bơi lội trong nước mở nhằm giảm thiểu rủi ro, và kết luận rằng việc có thêm thông tin về các phản ứng với sự ngâm mình trong nước lạnh và ấm, nguyên nhân của sự biến đổi cá nhân trong các phản ứng này cũng như các dấu hiệu cảnh báo về các sự kiện tim mạch, mà dường như là nguyên nhân chính gây tử vong trong các sự kiện OWS, sẽ giúp cho môn thể thao thú vị này trở nên an toàn hơn.
