Which safety equipment is recommended for protection against head injuries while paddling?

The recommended safety equipment for protection against head injuries while paddling is a helmet. A helmet is specifically designed to absorb impact and protect the head from potential hazards such as rocks, low-hanging branches, or other obstacles that could lead to injury while navigating in the water. Paddling can involve fast-moving water, rough conditions, and the potential for capsizing, making it crucial to have appropriate head protection to minimize the risk of serious injury.

The other options, while they serve specific purposes in various paddling scenarios, do not provide the same level of protection against head injuries. A leash is primarily used to keep the paddle close to you and prevent it from being lost, while a dry bag is designed for keeping gear safe and dry but does not offer any protective function. Correa, which may refer to straps or ties in some contexts, would similarly not provide the necessary head protection that a helmet does. Thus, the helmet is clearly the best choice for ensuring safety against head injuries during paddling activities.
