What action should divers take to avoid decompression sickness?

To avoid decompression sickness, divers should fulfill required safety stops during their ascent. This practice allows for a gradual decrease in pressure, giving nitrogen absorbed in the body enough time to safely eliminate from the tissues and bloodstream. When divers ascend rapidly, nitrogen bubbles can form, leading to decompression sickness. Safety stops, often taken at certain depths for a designated time, help mitigate this risk by allowing the body to release nitrogen appropriately as atmospheric pressure decreases.

Diving only at night does not influence the risk of decompression sickness, nor does it address the necessary behavioral practices during ascent. Additionally, changing dive partners frequently does not contribute to decompression safety; what matters is the adherence to dive tables, proper ascent rates, and completion of safety stops.
