How might a distressed swimmer indicate they need help?

A distressed swimmer typically indicates their need for help through visible and audible signals. Waving their arms or calling for help are direct actions that communicate urgency and the need for assistance. These behaviors reflect panic and a desire to be noticed, making it clear to potential rescuers that the swimmer is in trouble.

Other actions, such as diving underwater, swimming in circles, or remaining completely still, are not effective signals for requesting help. Diving underwater may prevent the swimmer from being seen, while swimming in circles might suggest confusion or disorientation rather than a clear distress signal. Remaining completely still could indicate exhaustion or submersion rather than a request for assistance, making it harder for rescuers to identify the situation. Thus, visible distress signals like waving or vocalizing are the most effective means for a swimmer to communicate their need for help.
