What is the recommended ascent rate for divers during normal diving activities?

The recommended ascent rate for divers during normal diving activities is 30 feet per minute. This rate is established to help minimize the risk of decompression sickness, often referred to as "the bends." Ascending at this controlled pace allows nitrogen, which has been absorbed by the body while under pressure, to be safely released as the pressure decreases.

A slower ascent provides the body adequate time to eliminate excess nitrogen through the lungs, ensuring divers can safely return to the surface without accumulating harmful nitrogen bubbles in their tissues or bloodstream. Additionally, this ascent rate allows for safety stops, typically at 15 feet for three minutes, which further aids in reducing the risk of decompression sickness.

While variations may exist depending on specific dive conditions or personal health factors, maintaining a maximum ascent rate of 30 feet per minute is a widely accepted standard in recreational diving practices.
