While you don’t need to be an athlete, a basic level of physical health is important. Divers should be able to swim, have normal lung and heart function, and be free of any conditions that could impact your ability to dive safely. Always consult with a doctor before starting if you have any medical concerns.

The minimum age for certification varies by agency and location, but typically, the minimum age is 10-12 years old. Younger divers can often participate in “Discover Scuba” programs or junior certifications.

Some medical conditions may limit your ability to dive safely. It's important to consult with a doctor familiar with diving medicine before participating in scuba diving if you have conditions such as asthma, heart disease, or other health concerns.

It is generally not recommended for pregnant women to scuba dive due to the potential risks to both mother and baby from changes in pressure and oxygen levels. Always consult a healthcare provider before deciding to dive while pregnant.

Most marine life is not dangerous if you respect their space. Never touch or provoke animals, and always follow your dive guide's instructions. If you encounter something threatening, remain calm, and slowly back away.
