YMCA Swim Instructor Practice Test

Waving hands can be a significant indication of a possible drowning situation. This behavior may signify that an individual is in distress and trying to signal for help. Unlike calm swimming or casually chatting with friends, which denote a swimmer's comfort and ease in the water, waving hands typically suggests a struggle or an inability to keep their head above the surface.

When someone is drowning, they might not be able to call out for help verbally due to the physical exertion and panic associated with the situation. Instead, the person might be trying to attract attention or alert others by waving their arms. This display of erratic behavior warrants immediate attention from lifeguards or instructors, as it can quickly escalate into a life-threatening situation if not addressed promptly.
