29 views

Humans can generally dive up to 60 meters (197 feet) underwater using scuba diving equipment. For professional free-divers, some can reach depths of over 100 meters (328 feet) on a single breath. However, diving deeper than these limits requires specialized training and equipment to avoid dangers like nitrogen narcosis and decompression sickness.

FAQs & Answers

  1. What is nitrogen narcosis? Nitrogen narcosis is a condition caused by the increased partial pressure of nitrogen at greater depths, leading to impaired judgment and reactions.
  2. How does decompression sickness occur? Decompression sickness occurs when divers ascend too quickly, causing nitrogen bubbles to form in the body due to rapid pressure changes.
  3. What equipment is necessary for deep diving? Deep diving requires specialized equipment like advanced scuba gear, dive computers, and sometimes mixed gases for safe depth management.
  4. What is the world record for free diving? The world record for free diving is over 100 meters, achieved by professional divers who have extensive training and experience.
