The air we breathe is approximately 78% nitrogen, an element vital for life as a component of proteins and nucleic acids. While atmospheric nitrogen is inert, its compounds can become toxic if they accumulate beyond healthy levels in the body, primarily impacting the kidneys and liver.

Scuba diving is a surprisingly physical activity, with some sources suggesting it can burn between 400-700 calories per hour, depending on the conditions. Given this energy expenditure, the question of 'should I do scuba diving with an empty stomach?' is critical for diver safety and performance.

Divers can lose a significant amount of fluids—between 0.25 to 0.5 liters per hour—underwater due to factors like breathing compressed air and immersion diuresis, which makes proper hydration a cornerstone of safe diving. This makes thoughtful nutritional planning just as important as your equipment checks.
