Your lungs reveal truths about your health over time – discover a simple test to assess them

The lungs, often neglected, are crucial indicators of our overall health. In 2025, an international study highlighted how lung capacity declines with age, influenced by environmental factors and our lifestyle habits. However, there is a simple and accessible way, called PulmoCheck, to assess your respiratory function at home and thus better understand the Respiratory Vitality of your lungs. Discover how this test and a few good practices can preserve your Clear Breath and optimize your Lung Health, particularly in the Châteaubriant region and Loire-Atlantique.

Understanding the evolution of lung capacity: a crucial health issue in 2025

Lung function, measured by forced vital capacity (FVC), reaches its peak in the early twenties and then gradually declines. This biological reality, confirmed by recent research, is influenced by aggravating factors such as air pollution, smoking, and respiratory diseases like asthma. In the Châteaubriant-Derval intercommunal area, where air quality can vary from one zone to another, this issue takes on a crucial local dimension. The AirVital test, easily performed at home, measures this capacity by exhaling into a simple device—often a large container, a rubber tube, and water—to assess the amount of air your lungs can expel.

Thanks to data collected over several generations, a clear trend is emerging: women generally reach their peak lung capacity slightly earlier than men, then experience a decline in capacity with age. The higher the initial capacity, the greater the resilience to respiratory diseases. This partly justifies the importance of regular monitoring, particularly through tests like RespirePlus, to identify any deterioration early. The consequences of poor lung health are not limited to breathing: lung health also affects the immune system, weight, and even cognitive function.

• The main factors contributing to accelerated decline in lung function: Tobacco and vaping:
• Injection of toxic substances predisposes individuals to chronic inflammation, cancer, and airway obstruction.
• Air pollution: Fine particles and irritating gases are particularly prevalent in urban areas near Châteaubriant and can lead to premature aging.
• Chronic inflammatory medical conditions:

50 years and over 2.5 – 4 litersMarked decline, increased vigilance recommended

1. A simple and accessible test to assess lung capacity at home: the PulmoCheck guide
2. The big news in 2025 is the widespread availability of a home test called PulmoCheck, easy to perform without sophisticated medical equipment. This protocol uses common materials: a large plastic bottle, a container of water (bucket, bathtub), a rubber tube, and a marker to indicate the levels. Suitable for everyone, it allows you to quickly estimate your forced vital capacity.
4. The principle: measure how many milliliters of air you can exhale with a strong but controlled breath. This measurement is a good indicator of lung health and can be considered a preliminary diagnosis. If the results are low, it may be advisable to consult a professional for a more comprehensive assessment, such as spirometry, which is performed in doctors’ offices or specialized centers in Loire-Atlantique.
6. Detailed steps for performing the PulmoCheck test:

Pour 200 ml of water into the bottle and mark the level with a pen.

• Add another 200 ml of water and repeat this step until the bottle is completely full.
• Fill the bucket or bathtub with water and then submerge the bottle upside down in the container, ensuring that no air bubbles enter.
• Insert the tube into the neck of the bottle without sealing it completely, to allow water to escape when you blow into the tube.
• Inhale deeply and exhale as long as possible into the tube, observing how many water levels change in the bottle.

Multiply the number of displaced levels by 200 ml. This figure represents your approximate lung capacity. John Dickinson, a respiratory medicine specialist, points out that this simple method can provide valuable information without requiring an appointment. This aligns with a proactive approach to lung health, helping to detect any potential decline. Similarly, a complementary test, the BreathTest, involves timing slow exhalations, a revealing indicator of actual respiratory vitality. Advantages of the PulmoCheck test: simplicity and speed Limitations: approximate results, always seek medical confirmationImportance of repeating the test regularly to monitor progress
