根因分析

直接逆着离岸流游泳会迅速导致力竭，因为水流速度超过人类游泳速度；正确策略是平行于海岸游泳以脱离狭窄的水流。

English

Swimming directly against a rip current causes rapid exhaustion because the current is stronger than human swimming speed; the correct strategy is to swim parallel to the shore to exit the narrow current.

解决方案

  1. 平行于海岸线游泳，直到感觉水流减弱，然后以斜角游回岸边。示例：如果被离岸流困住，呼救后向左或向右沿着海滩（平行）游20-30米，直到水流减弱，然后斜向游回。
  2. 冷静地漂浮或踩水，让水流将您带到碎浪区外，然后以斜角游回。示例：如果无法平行游泳，仰面漂浮，保持头部在水面上，等待水流消散（通常在离岸50-100米处），然后用侧泳游回。

无效尝试

常见但无效的做法:

  1. Dive under the rip current to escape 75% 失败

    Rip currents are surface and subsurface flows; diving under does not avoid the current and wastes energy.

  2. Tread water and wait for the current to stop 70% 失败

    Rip currents can extend hundreds of yards offshore; treading water leads to exhaustion and hypothermia.
