What is a major risk of diving in strong currents?

Diving in strong currents significantly increases fatigue for divers. When faced with strong water movement, divers must exert more effort to maintain their position, navigate, or make progress against the current. This can lead to rapid depletion of physical energy, as the diver's muscles work harder to counteract the force of the water. Additionally, the constant struggle against the current can lead to increased air consumption, further contributing to fatigue.

This increased fatigue is critical for divers to recognize because it can impair their judgment and physical abilities, potentially leading to unsafe situations such as getting separated from a group or miscalculating air supply. Understanding how currents affect energy expenditure helps divers prepare appropriately for their dives, including planning for adequate rest and ensuring they are in good physical condition before entering the water. Balancing the exertion needed to handle strong currents is essential in maintaining safety underwater.
