When we think about aging, we often imagine wrinkles, joint pain, loss of muscle mass, and even forgetfulness or cognitive problems. But other organs also change over time, and the lungs are rarely talked about.
These organs work tirelessly: We breathe more than 20,000 times per day. Although we rarely think about them until something goes wrong, there are small daily habits that can make a difference in how we breathe in the coming years.
The evidence shows that from the age of 30 or 35, lung function begins to gradually decline. The lungs lose elasticity, the respiratory muscles weaken, and oxygen exchange becomes less efficient. Although this process is natural, some habits can accelerate it and others can help slow it down.
A key first step is to protect the lungs from injury and disease. To that end, the National Heart, Lung, and Blood Institute (NHLBI) recommends:
- Do not smoke and avoid secondhand smoke.
- Reduce exposure to pollutants (both indoors and outdoors).
- Protect yourself against seasonal respiratory illnesses.
Daily habits that help you breathe better
In addition to preventing illnesses and injuries, we can also work on other daily habits that help preserve respiratory capacity. One of them is exercise.
Experts explain that a sedentary lifestyle can affect respiratory efficiency even in people without lung disease. This happens because when the body moves little:
- The respiratory muscles work less.
- Aerobic capacity decreases.
- Feelings of tiredness increase.
- Deep breathing becomes less frequent.
Over time, this can translate into less physical stamina and more fatigue in everyday activities.
Although many people believe that respiratory benefits are only achieved by running or doing intense cardio exercise, there is good news: walking regularly also has important benefits. This simple habit helps improve oxygenation, circulation, and the efficiency with which the body uses oxygen.
Furthermore, walking naturally forces you to regulate your breathing and can help reduce stress, another factor related with shallow breathing and chest tension.
Stress and poor sleep are two more factors that must be taken into account to preserve respiratory capacity, as this can cause:
- Muscle tension.
- A feeling of tightness in the chest.
- Tiredness.
- Difficulty relaxing.
Poor sleep can disrupt breathing patterns and increase physical stress levels, hindering the body's recovery. You can check our Health Guide to improve the quality of your sleep.
Other habits that can make a difference in the long run are:
- Breathe through your nose: this filters, humidifies, and warms the air before it reaches the lungs. In contrast, habitually breathing through the mouth avoids part of that process and can promote dryness, irritation, and less efficient breathing.
- Practice conscious breathing: simple slow breathing exercises can help improve feelings of well‑being and reduce physical tension.
- Avoid heavy meals: this can cause abdominal bloating and put pressure on the diaphragm, preventing it from moving properly.
- Maintain a healthy weight: excess weight can make it harder for the lungs to expand and increase breathing effort.
- Use protective equipment: especially if there is a risk of exposure to contaminants in the workplace.
Although we rarely think about them, our lungs accompany us every moment of our lives. Incorporating small healthy habits today can help preserve not only good breathing, but also energy, rest, and quality of life in the years to come.
