[DIVE SAFETY] Fortunately,ear injuries are preventable. Your middle ears are dead air spaces, connected to the outer world only by the Eustachian tubes running to the back of your throat. If you fail to increase the pressure in your middle ears to match the pressure in your outer and inner ears, the result is painful middle ear barotrauma, the most common pressure-related ear injury.
Injuries due to exposure - Altitude sickness
Traveling to high altitudes exposes travelers to increasingly rarefied air and progressively decreasing amounts of oxygen, resulting in declining levels of oxygen in the blood and thus impaired physical and mental performance.
The Silent killer: Carbon Monoxide
Hazard identification and risk assessment (HIRA), a programme based on general safety principles and adapted to suit the situations to which it is applied, is a tool that can empower dive businesses and professionals to assess, acknowledge and then address their approaches to their risks
Cannabis & Diving
Cannabis/ marijuana has been known to man for thousands of years.

How the dive Reflex protects the brain and heart
Simply being immersed in water creates a hydrostatic pressure effect on the body that essentially squeezes some of the blood from our extremities back toward our heart. The vagus nerve also causes certain blood vessels to constrict.
Scuba Diving and Life Expectancy
Diving burns more calories than many people think. It is a very gentle form of exercise, but it is exercise nonetheless. When divers breathe air or nitrox at depth, reactive oxygen species are produced. Otherwise known as free radicals, these molecules have been found to be negatively associated with diseases and aging.
