Fatigue, body weight, and dehydration can all lead to what condition in divers?

The condition that can be influenced by factors such as fatigue, body weight, and dehydration in divers is decompression sickness. Decompression sickness, often referred to as "the bends," occurs when divers ascend too quickly after spending time at depths where they have absorbed significant amounts of nitrogen under high pressure.

Fatigue can compromise a diver's physical performance and decision-making abilities, potentially leading to poorly timed ascents. Increased body weight can affect a diver's buoyancy, making it difficult to maintain proper ascents and descents, while also influencing how quickly nitrogen is absorbed. Dehydration reduces the body's ability to efficiently eliminate nitrogen, increasing the risk of bubble formation when a diver ascends and experiences lower pressure.

Understanding the interplay of these physical factors is crucial in diving safety. Proper hydration and rest are essential for ensuring that divers can safely manage their ascent and avoid the risks associated with decompression sickness.
