Being on land does not remove breath-hold risk. Hypoxia can impair judgment and consciousness quickly, so prepare the environment, posture, breathing, and supervision before thinking about time.

Choose a fall-safe environment
Do not practice in water, a bath or shower area, while driving or moving, or while standing. Use a stable seated or reclined position near the floor and clear nearby hazards. For challenging practice, have a capable person nearby who recognizes warning signs and knows how to respond.
Hyperventilation is not a safety margin
Repeated fast or deep breaths can delay the urge to breathe without removing the risk of low oxygen. DAN explicitly warns about hyperventilation and hypoxia. Breathe normally and comfortably; do not let an app direct breath preparation or pressure you toward a maximum.
Stop without negotiating
Return to normal breathing and end the session for dizziness, tunnel vision, ringing ears, confusion, loss of motor control, unusual pain, or panic. A shorter result is not a failure. For repeated symptoms or health concerns, consult an appropriate medical professional and qualified freediving instructor before resuming.
Three questions before starting
Am I completely away from water and dangerous edges?
Am I prepared to stop without hyperventilating or chasing a record?
Can I return to normal breathing and get help immediately if my condition changes?
