What is a sign that seasickness is affecting you while diving?

  1. Feeling overly confident

  2. Developing a headache

  3. Experiencing nausea or vomiting

  4. Improving your buoyancy control

The correct answer is: Experiencing nausea or vomiting

Experiencing nausea or vomiting is a clear sign that seasickness is affecting you while diving. Seasickness occurs when there is a conflict between the sensory input related to motion. When you are in a moving environment, such as on a boat or while diving in choppy waters, this sensory mismatch can lead to symptoms of motion sickness. Nausea is one of the most common symptoms associated with this condition, often accompanied by vomiting. Other signs of seasickness can include dizziness or a general feeling of malaise, but nausea and vomiting are the most distinct indicators that your body is struggling to cope with the movement. Recognizing these signs early is crucial for your safety and comfort while diving, as they can lead to decreased focus and impairment of diving skills if not addressed promptly.
