What is the purpose of a life jacket during water activities?

The primary purpose of a life jacket is to ensure the wearer can float in water. Designed to provide buoyancy, life jackets help prevent drowning by keeping an individual’s head above water, even if they are unconscious or unable to swim. This safety feature allows individuals to float and maintain their position in the water, increasing their chances of survival until help arrives or they can reach safety.

While other options touch on certain aspects associated with life jackets, such as visibility and warmth, they do not capture the essential function that makes life jackets critical for safety during water activities. The design and material of life jackets primarily focus on buoyancy rather than aesthetics or warmth, underscoring the importance of keeping individuals afloat in emergency situations.
