The average, untrained person can hold their breath for 30 to 90 seconds. While this might seem short, the physiological processes involved are complex. So, how long can a man stop his breath and what happens internally during this time?
The Physiology of a Breath-Hold
Understanding the limits of holding one's breath requires examining the body's physiological response. Contrary to popular belief, the primary trigger for the urge to breathe is not a lack of oxygen, but a buildup of carbon dioxide (CO2). As you hold your breath, your body continues to produce CO2 as a metabolic byproduct. This CO2 dissolves in the bloodstream, increasing its acidity. Special chemoreceptors, particularly those in the brainstem, detect this rise in CO2 and send signals to the diaphragm, causing involuntary contractions.
The Role of Oxygen Deprivation
While CO2 is the main driver, oxygen depletion (hypoxia) is the ultimate danger. The brain and heart are the most oxygen-sensitive organs. Prolonged hypoxia can lead to:
- Dizziness and lightheadedness
- Loss of motor coordination
- Peripheral vasoconstriction (narrowing of blood vessels)
- Ultimately, unconsciousness (blackout)
The mammalian diving reflex, an involuntary response triggered by cold water contact on the face, helps conserve oxygen by slowing the heart rate (bradycardia) and diverting blood flow to vital organs. This reflex is exploited by professional freedivers to increase their breath-hold time.
Average vs. Elite: A Tale of Two Timelines
There is a vast difference between the casual breath-hold of an average person and the professional attempts of elite freedivers. An average, healthy man's experience is governed by the overwhelming CO2 reflex, typically ending between 30 and 90 seconds. Competitive freedivers, on the other hand, train for years to increase their tolerance to high CO2 levels and low oxygen.
The Guinness World Records
Professional feats highlight the extreme limits of human endurance:
- Static Apnea (unassisted): The current record is an impressive 11 minutes and 35 seconds, achieved by Stéphane Mifsud in 2009. This is done with only a single breath of ambient air.
- Static Apnea (assisted): For this category, competitors breathe 100% pure oxygen before the attempt. The record, set by Vitomir Maričić in 2025, is an astonishing 29 minutes and 3 seconds. This oxygen pre-load dramatically increases the initial oxygen saturation in the blood, delaying the onset of hypoxia.
Comparison: Average Man vs. Elite Freediver
| Feature | Average Man (Untrained) | Elite Freediver (Trained) |
|---|---|---|
| Typical Hold Time | 30–90 seconds | 3–12+ minutes |
| Primary Limiter | Buildup of carbon dioxide | Hypoxia (lack of oxygen) |
| Training Required | None | Years of specialized training |
| Associated Risks | Mild lightheadedness, faint | Hypoxic blackout, drowning |
| Motivation | Curiosity, bragging rights | Competition, personal challenge |
Dangers and Safe Practices
It is crucial to understand that practicing breath-holding, especially underwater, carries significant risks. Never attempt to push your limits underwater or alone. The most dangerous risks include:
- Shallow Water Blackout: This occurs when a diver hyperventilates (breathing rapidly) before a dive, lowering CO2 levels and delaying the breathing reflex. The brain can run out of oxygen and cause a blackout before the diver feels the need to surface, often leading to drowning.
- Hypoxia: Oxygen deprivation to the brain and heart can lead to fainting and potentially organ damage if prolonged.
- Cardiac Events: In extreme cases, the stress on the body can cause cardiac issues.
Can You Safely Increase Your Breath-Hold Time?
For recreational purposes, it is possible to moderately increase your breath-hold time using safe techniques. This training focuses on improving lung efficiency and CO2 tolerance, not on pushing yourself to dangerous extremes. All practices should be done with a spotter, preferably out of the water.
- Diaphragmatic Breathing: Focus on breathing deeply using your diaphragm, rather than shallow chest breathing. This helps increase overall lung capacity and prepares your body for efficient oxygen exchange.
- Breath-Hold Tables: Developed by freedivers, these are structured training regimens that involve repeating breath-holds of increasing duration, separated by controlled breathing intervals. They are designed to gradually increase your tolerance to CO2.
- Mental Relaxation: Maintaining a calm and relaxed state is essential. Stress and anxiety increase heart rate and oxygen consumption. Practicing meditation and focusing on calming thoughts can extend your time significantly.

Conclusion
While the average man can hold his breath for under a minute, the limits of human apnea are astounding, thanks to the intense training and physiology of freedivers. The crucial takeaway is the importance of safety. Never compromise your health by pushing to the point of blackout, especially in water. For the average person, improving breath control offers benefits in managing stress and anxiety, but attempting world-record feats should be left to professionals under strict, supervised conditions.
