Life jackets should be worn any time in or around water to ensure safety. The rationale behind this guideline is rooted in the unpredictability of water environments. Even in seemingly calm conditions, accidents can happen unexpectedly, and having properly fitted life jackets readily available significantly reduces the risk of drowning. This precaution is vital not just during activities like swimming or water sports but also when in proximity to water bodies, as individuals may inadvertently fall in or encounter unexpected situations.

While it may seem sufficient to wear life jackets only during specific activities or ages, such as for children under 12 or during water sports, these practices do not account for accidents that can occur at any moment. Thus, promoting the use of life jackets consistently emphasizes safety and encourages responsible behavior around water.
