Imagine descending to a beautiful reef. The water is clear, fish glide past, and then you feel a strange pull on your face, like the mask is trying to suction itself onto your eyes. When you surface your eyes are red, swollen, and possibly bruised. The cause was mask squeeze, a common but preventable dive injury.
As a dive professional, I enjoy seeing divers coming out for their first ocean dive. A new diver is easily excited by every little detail, and it takes just one wonderful experience underwater to make diving a lifetime hobby.
Emmanuel “Manu” Dugrenot, PhD, a senior researcher at Divers Alert Network (DAN), brings cutting-edge physiological research to the development of safety protocols for both technical and recreational diving.
While growing up I had two lifelong goals: become a diver and join the military to be part of the elite Special Operations Forces. I became a certified diver in 1994, when a close friend convinced me to plunge into Louisiana’s lakes with him, and I joined the U.S. Army a year later.
Divers Alert Network (DAN) provides the industry’s most comprehensive cardiopulmonary resuscitation (CPR) and first aid training, grounded in evidence-based practices. Our programs leverage DAN’s research and medical expertise, along with the internationally recognized guidelines established by the International Liaison Committee on Resuscitation (ILCOR).
Urinating in a wetsuit is common for many recreational divers and is generally not harmful when exposure is limited.

Most divers feel that urge within minutes of entering the water.
