Explain the significance of the 'no-decompression limit'.

The 'no-decompression limit' is crucial for divers as it represents the maximum amount of time they can spend at a specific depth without requiring staged decompression stops during their ascent. When divers exceed this limit, they risk decompression sickness, also known as 'the bends', which occurs when nitrogen bubbles form in the body as a diver ascends too quickly after spending too long at depth.

Understanding the no-decompression limit allows divers to plan their dives effectively, ensuring that they can safely return to the surface without the need for additional decompression procedures, which can complicate the dive experience and require more time and considerations. By adhering to these limits, divers can enjoy their underwater activities with a reduced risk of injury related to pressure changes.

This concept is foundational in dive planning and safety, and it is essential for divers to familiarize themselves with the specific limits associated with their diving tables or dive computers, ensuring a safe and enjoyable diving experience.
