As a whole, scuba diving had a drop of 4.7% in participation in 2020 — a negative trend in place for over a decade. The silver lining is what we mentioned earlier: The participation rate in the group of core divers (those scuba diving more than 8 times per year) increased 1.3% over 2019.

What are the side effects of scuba diving?
Diving compressed gases (ie, scuba diving) can lead to two very serious medical conditions: Decompression Sickness (DCS), otherwise known as “the Bends,” and Pulmonary Over-Inflation Syndrome (POIS).
Who is not allowed to scuba dive?
People with ear problems or people who have had ear surgery in the last 12 months. People with a cold, flu or congestion. It is not recommended that people with a cold take decongestion medication in order to dive, as this can wear off underwater and cause problems while ascending to the surface.

Are there any long term effects of scuba diving?
Evidence from experimental deep dives and longitudinal studies suggests long-term adverse effects of diving on the lungs in commercial deep divers, such as the development of small airways disease and accelerated loss of lung function.
What is divers lung?
Also known as mediastinal emphysema to divers, pneumomediastinum is a volume of gas inside the mediastinum, the central cavity in the chest between the lungs and surrounding the heart and central blood vessels, usually formed by gas escaping from the lungs as a result of lung rupture.
