Diving deaths from fatalities involving cardiac issues have increased, largely due to obesity and undiagnosed heart disease.

Diving Deaths in Australia: A 50-Year Retrospective

A landmark study published in the International Journal of Environmental Research and Public Health examines 50 years of Australian scuba diving fatalities, revealing striking changes in diver profiles and causes of death between the periods 1972–1999 and 2000–2021. Despite average annual deaths remaining steady (about 8.5 per year), the characteristics of those lost—and the contributing factors—have evolved dramatically.

A correlation between longer life expectancy and water was clear for those who live within about 50km (30 miles) of an ocean or gulf.

Living Close to the Sea May Add Years to Your Life

New research suggests that living near the ocean may be good not only for the soul, but also for longevity. A study led by Ohio State University found that people living within 50 km of the coast tend to live about a year longer than the U.S. national average. Environmental and lifestyle factors—including milder climates, better air quality, and access to recreational activities—are likely contributors.

Neclecting to routinely equalise mask pressure during descent can cause dramatic bruising around the eyes and other soft tissue injuries.

Mask Squeeze Can Mimic Facial Trauma

A recent forensic case study has drawn attention to how a diver's failure to equalise mask pressure during descent can lead to facial injuries that resemble blunt trauma. Known as "mask squeeze" or facial barotrauma, this condition can cause dramatic bruising around the eyes and other soft tissue injuries when negative pressure develops inside a dive mask.

DAN Names Cliff Richardson as Next CEO

As CEO, Richardson will lead the organization in its mission to assist injured divers and advance dive safety. He will succeed DAN’s current president and CEO, Bill Ziefle, who first joined DAN as a board member in 1998 and was appointed CEO in 2010. Ziefle’s distinguished career at DAN has been marked by a demonstrated commitment to dive safety and significant growth in DAN’s membership and insurance programs.

The hyperbaric chamber at Rigshospitalet, Denmark’s national hospital, also treats divers with decompression illness.

Hyperbaric Chamber Deaths Raise Questions—but Divers Should Not Worry

A tragic incident in Arizona on 11 July has ignited some public debate and concerns around the safety of hyperbaric oxygen therapy. A physical therapist died following a flash fire inside a hyperbaric chamber at a health and wellness clinic in Lake Havasu City, which was not a medical-grade hyperbaric therapy facility. This is the second such fatality reported in the United States this year. In a similar case, a 5-year-old boy died in February when an oxygen-rich chamber exploded at a Michigan clinic.

DAN Introduces 2025 Interns

The DAN internship program was started in 1999 to give qualified candidates valuable experience in dive safety research. 

While the program is still research-oriented, its scope has expanded over the years to include projects that focus on other aspects of DAN’s mission to help divers in need of emergency medical assistance and to promote dive safety through education. 

Today, DAN interns participate in a range of activities including field work, lab studies, outreach, training program development, and other projects that promote dive safety.

Knee Replacement and Diving

I thought to myself, You’ve got to be kidding. Me? I’ve never had any kind of surgery, never had any broken bones, I was a dedicated and consistent runner, and most importantly, a very active SCUBA diver. How could this be?

This journey started several months earlier when I noticed some stiffness and discomfort in my left knee during a routine early morning run in my neighborhood. I immediately stopped and avoided running for a few days. When I tried running again, I had the same discomfort, and I noticed that my knee was a little swollen.

There are now significant gaps in the coverage of hyperbaric treatment facilities in England.

England Faces Critical Shortage of Hyperbaric Chambers for Divers

This decision follows a recent procurement process where three recompression chambers in the Midlands, North West, and North East of England were unsuccessful in their bids to continue providing HBOT services. The British Sub-Aqua Club (BSAC) warns that this could leave vast regions without accessible treatment for decompression illness (DCI) and arterial gas embolism (AGE), conditions that require immediate medical attention.

DAN Launches Continuing Education for Dive Professionals Course 2: Boat Diving

This free course focuses on risk mitigation on dive boats and is now available to all dive professionals via DAN E-Learning. DAN expects this program will not only enhance divers’ safety but will also help reduce dive operators’ liability risk.

To encourage participation, DAN is offering discounted premiums on individual professional liability and group professional liability insurance to all DAN members who complete the e-learning, which can be done in about an hour.
