Are there any health concerns I should be aware of?

Individuals with respiratory or cardiovascular issues should consult a doctor before freediving. It's crucial to be in good health due to the physical demands of the sport.

Do I need a medical certificate to freedive?

While a medical certificate isn't always mandatory for short courses, it is highly recommended, especially if you have pre-existing medical conditions related to breathing or heart issues. Freediving schools like those in Tulum may require a health declaration, so check with your instructor beforehand to ensure you meet any medical prerequisites.
