To prevent dehydration while on the water, you should drink some water at least ____________.

The recommendation to drink water every 15-20 minutes while on the water is based on the need to maintain proper hydration, especially in an outdoor environment where factors such as sun exposure, physical activity, and wind can increase the risk of dehydration. When engaging in activities on the water, individuals can often become unaware of their hydration levels until significant thirst sets in, which is a late signal of dehydration.

Regular intake of water at short intervals helps to proactively manage and prevent dehydration before it occurs, ensuring that the body remains well-hydrated. This approach is particularly crucial in hot weather or during physical exertion, as both can accelerate fluid loss through sweat.

Some other choices suggest less frequent hydration intervals or waiting until thirst is felt, which may not be adequate for maintaining optimal hydration levels during outdoor activities. By adhering to the guideline of drinking water every 15-20 minutes, individuals can foster a habit that promotes consistent hydration and supports overall health and safety while boating.
