Freediving is a strenuous activity carried out in the underwater environment, which may, under certain conditions, increase your risk of injury. This risk may be significantly increased if you have certain physical conditions. These same physical conditions would not necessarily be a safety factor in other strenuous activities or sports. AIDA therefore uses the following questionnaire to make you aware of these conditions. Failure to address these conditions prior to engaging in breath-hold diving activity may endanger your health, your safety and the safety of any person you may dive with in the future.
