Lung Care: A Complete Guide to Keeping Your Lungs Healthy and Strong
Each day, the lungs work around the clock performing somewhere around 20,000 cycles of respiration (breathing in oxygen). When there are challenges and complications, people seldom think about their lung health as a whole. However, if you suffer from seasonal allergies, have experienced a respiratory infection, or just want the ability to breathe normally again, investing in lung health will also benefit the rest of your body.
Throughout this article, we will provide you with some facts on how you can care for your lungs and participate in daily activities that improve your respiratory system, along with understanding what to look for so that you do not miss warning signs that may warrant a visit to see your doctor.
Why Lung Health Matters More Than Ever
With more and more people becoming concerned about respiratory health around the globe, this is now a top priority for many. Chronic Respiratory Disease (CRD) is one of the leading global diseases, as reported by the WHO, and is killing millions of people every day. There are over 300 million people globally with CRD-like conditions, including COPD, asthma, and lung infections, most of which could be avoided through effective management and treatment.
Please note that even though you could be perfectly fit and have never smoked, your lungs are still suffering from exposure to pollutants, allergens, viruses, and bacteria daily. The good news is that your lungs are fairly durable and that making small, cost-free changes to your daily life can drastically improve your lung function for many years to come.
Top Tips for Better Lung Health
1. Stop Smoking—and Avoid Secondhand Smoke
The main point in the entirety of this article is simply this: smoking is absolutely the worst thing that you can do for your lungs; therefore, you should quit. Cigarettes contain over 7,000 different types of chemicals; many of these are categorized as toxic and/or could potentially lead to cancer (i.e., carcinogenic). Smoking will lead to the destruction of lung tissue over time and will cause the narrowing of your airways, and your risk of developing lung cancer and/or chronic obstructive pulmonary disease (COPD) will be increased dramatically.
There’s also an additional reason why quitting is important—i.e., secondhand smoke has an almost identical effect on your lungs as if you smoked yourself. If you live with a smoker or work in an environment where people smoke, you are being exposed to the same harmful toxins. By asking a family member to smoke outside, or by advocating for smoke-free policies at work or where you live, you can set boundaries against secondhand smoke.
Before you quit, you may want to speak to your doctor about how using nicotine replacement products, medications that can be prescribed to you, or joining support groups may help to make the process of quitting easier. You will begin to heal your lungs only weeks after quitting smoking.
2. Exercise Regularly to Strengthen Your Lungs
Just like every other part of the body that contains muscle, your lungs can be improved through regular physical activity or exercise. The majority of exercises that utilize the muscles of the legs (brisk walking, jogging, swimming, and cycling) require the lungs to work harder than they would while performing normal activities, thus improving both the size and function of the lungs over time.
Another way to promote lung health is through breathing exercises such as deep breathing, yoga, and tai chi. They help you become aware of how to breathe slowly and deeply so that you can draw in more oxygen to the lower regions of the lungs. An example would be unidirectional breathing (also known as diaphragmatic breathing): place one hand on your chest and the other on your abdomen, then take a deep breath in through your nose and allow your abdomen to rise (keeping your chest relatively still). This should be followed by a slow exhale through pursed lips. Practicing this technique for approximately 5 to 10 minutes a day may promote an increase in lung capacity.
3. Protect Yourself from Air Pollution
The quality of the air we breathe can differ significantly by location and season, as well as from day-to-day throughout the year. When the Air Quality Index (AQI) level is high outside, refrain from engaging in such things as participating in strenuous outdoor activities (including exercising, etc.) due to potential negative effects on your health. You should also wear a well-fitted mask if you choose to engage in outdoor activities due to high AQI levels.
The quality of indoor air is just as important; there are many sources of indoor air pollution commonly found in our homes, including dust, mold, pet dander, volatile organic compounds (VOCs) from various cleaning products, and/or fumes generated from cooking. Ways to improve indoor air quality include the following:
Using a HEPA air filter for the air circulation system (HVAC system) in your home or office, particularly in your bedrooms,
Routine change out of the HVAC filter
Opening windows on days when there is less pollution to provide fresh air circulation into and out of the house
Utilising only natural and fragrance-free cleaning products in all home and office locations and surfaces
Controlling relative humidity levels to a range of 30% – 50% for homes/offices minimises the risks for mould development within an indoor environment. Maintain Air Quality.
4. Prevent Infections with Smart Hygiene Practices
Older adults or patients who already have chronic respiratory problems are more likely to experience serious lung injury from respiratory infections, including influenza, pneumonia, and COVID-19. There are different ways to prevent these infections and, therefore, reduce the chance of developing potentially harmful lung damage.
What Can You Do to Prevent Respiratory Infections?
Wash hands regularly with soap and water; don’t touch your face; avoid close contact with sick individuals; during flu season, wear a mask in crowded indoor public settings; keep current with flu vaccinations (get a flu shot); keep current with pneumonia vaccines (as your physician recommends); get vaccinated against COVID-19 (as appropriate).
5. Eat Foods That Support Lung Health
Although no one particular item will help to mend any damaged lungs, eating a well-balanced diet, as well as a variety of foods containing each nutrient group level, will reduce all forms of inflammation, thereby supporting the body’s normal way of functioning with respect to how its lungs function normally or optimally. Foods high in antioxidants (fruits/vegetables), fat (omega-3s), and vitamins (C, D, E) are all good candidates for this goal.
Some examples of what types of food might help to make up a “lung-friendly” food list include:
Leafy green vegetables (spinach, kale)
Fatty fish (salmon, mackerel, sardines)
Fruits (berries, citrus, bell peppers)
Nuts and seeds (walnuts, flaxseed)
Herbs and spices (garlic, ginger, turmeric) with natural anti-inflammatory properties
Additionally, staying hydrated by consuming adequate amounts of water regularly is also vital for maintaining a clear, thin mucous lining in your airway so it is easy for the body to maintain a clear, healthy airway by being able to remove mucus by naturally detoxifying the lungs.
6. Practice Good Posture
Sitting and standing up incorrectly causes the lungs to be compressed; therefore, less air will be taken in compared to if a person were to sit or stand properly. When sitting or standing correctly, your lungs can expand fully. Be sure to take breaks throughout your day and get up, stretch, and take several deep breaths if you find yourself working at a desk for long periods of time.
Symptoms of Respiratory Issues That Should Never Be Ignored
Although sometimes being short of breath while exercising is typical, if you begin experiencing chronic or worsening respiratory symptoms, you should seek medical evaluation. If you develop any of the following respiratory symptoms, make an appointment with your doctor without delay:
– A persistent cough for 8 weeks or more
– Shortness of breath with normal daily activities
– Noisy / wheezing breathing
– Pain or tightness in your chest
– Coughing up blood
– Frequent respiratory infections
– Unexplained loss of energy or weight
Early detection of chronic lung diseases such as COPD, asthma, and lung cancer can improve the success rate of treatment by having an early diagnosis versus waiting until the disease is far advanced to receive medical care.
The Role of Regular Health Screenings
If you smoke and are older than 50, take the opportunity during your next visit with your doctor to discuss annual low-dose CT scan screening for lung cancer. This fast and painless method of detecting lung cancer can identify it at an earlier stage, allowing for a better chance of being successfully treated than if found at a later date. Those who have a family history of lung problems or have been exposed to asbestos, silica, or other harmful substances may also benefit from receiving spirometry testing.
Spirometry measures the volume of breath you can exhale, as well as how quickly you can produce that volume. It can be helpful with diagnosing both asthma and chronic obstructive pulmonary disease (COPD), as well as determining whether or not treatments are having the intended effects.
Can Supplements Help Your Lungs?
Many individuals question whether herbal supplements or vitamins can help improve their lung health and functional capabilities. While a variety of nutrients—including many vitamins—are generally available through food sources and can provide lung support, you may require extra support using these supplements.
Below are some of the most common types of supplements recommended for lung support: – N-acetylcysteine (NAC) acts as an antioxidant and can help thin mucus and aid in reducing inflammation.
– Low vitamin D levels have been linked to having worse outcomes from respiratory diseases.
– Omega-3 fatty acids may help reduce inflammation in the bronchial tubes.
– Quercetin is found in plants and can act as an antioxidant, as well as help to decrease the amount of inflammation in the body.
If you are considering starting a new vitamin, supplement, or herb to assist with lung health and function, you should consult your medical provider before beginning any kind of supplementation, especially if you have an existing lung condition or are on prescription medications.
Final Thoughts – Breathe Easy, Live Long
You have probably heard references to the “silent heroes” in our bodies, but there’s no doubt that the lungs are also silent heroes and deserve expert care as much as your heart, brain, and muscles. By avoiding the consumption of cigarettes, exercising regularly, using air filtration services to protect yourself from polluted air, and adopting a healthy diet full of nutrients that nourish the lungs, you can maintain a strong respiratory system for years to come.
Choose one or two of these recommendations found within this article and begin small by incorporating those into your daily routine. Over time, creating a healthy habit has been proven to greatly improve a person’s lung health and, therefore, their quality of life.
