What is a common sign of overexertion while diving?

Excessive fatigue and difficulty maintaining a normal breathing rate are significant signs of overexertion while diving. When divers engage in strenuous activities without the appropriate conditioning or if they push themselves beyond their limits, they may experience fatigue that affects their overall performance and safety in the water.

This excessive fatigue can lead to a decrease in the ability to maintain a normal breathing rate, which is crucial for effective gas exchange and safe diving practices. An irregular or overly rapid breathing rhythm may indicate that the body is struggling to cope with the demands placed upon it. Recognizing these signs allows divers to take necessary action to rest and recover, ensuring safe diving practices.

In contrast, increased alertness, enhanced buoyancy control, and improved underwater visibility are not characteristics associated with overexertion. Instead, they might suggest that a diver is in a relaxed and focused state, which is ideal for a safe and enjoyable dive.
