Children, Adults & Seniors: How Lung Health Risks Change Across Life Stages

Lung development of the fetus depends on the physical and genetic health of the parents.

At birth, breathing begins with air from the environment, containing oxygen and other gases, and is influenced by known and unknown forces of nature. The air then passes through well-developed nostrils, which regulate the air temperature and prevent foreign bodies from entering the body and help protect against diseases. 

Breath travels through the nasal passages, sinuses, pharynx (throat), larynx (voice box), trachea (breathing tubes), bronchi, small airways, air sacs, interstitial membrane, into thin-walled blood vessels that transport oxygen and collect gases and other substances to be expelled from the body. 

The diaphragm, the muscle that separates the lungs from the abdomen, is the most powerful breathing apparatus. 

The lungs in the early stages of life undergo dramatic changes from newborn→ infancy→ childhood→ puberty→ teenage→ adults→ middle age→ seniors. Factors influencing lung health risks keep changing with age, depending on genetics, environment &amp; external factors.

<ul><li>Genetics or abnormalities – disorders at birth, transmitted from parents. Stress, environment, nutritional deficits, and accidents play an important role in lung and airway development. Also, anatomical abnormalities of the airways since birth, whether corrected or correctable or left alone. </li></ul>

<ul><li>Allergy—genetic or acquired is lifelong unless well managed</li></ul>

<ul><li>Chronic health conditions – Asthma can occur during childhood, pregnancy, post-pregnancy, or later in life and is generally manageable. Diabetes can develop during childhood, in young adulthood, or later in life, but it can be managed effectively. Hypertension, including pulmonary hypertension, can occur at any age and may be caused by blood clots, underlying diseases, primary conditions, or genetic factors.</li></ul>

<ul><li>Environmental factors and unhealthy habits – smoking, pollution, gases, drugs, near-drowning. Recreational drugs, or side effects of medications used for diseases of the body, can have a telling effect on the lungs and airways.</li></ul>

<ul><li>Nutrition – inadequate nutrition of mother and child can cause damage till old age </li></ul>

<ul><li>Occupational lung disease – at any stage – workplace, smoking, birds, pets, pollution, construction activity, dusty atmospheres and travel, which may cause difficulty in breathing till later in life, leading to chronic obstructive lung disease that may cause morbidity.</li></ul>

<ul><li>Infections – Can occur during childhood or throughout life, affecting both healthy individuals and those with reduced immune function, which may be due to co-existing diseases, medications that suppress the immune system to prevent rejection of transplanted organs, congenital immune deficiencies, or acquired immune deficiencies resulting from medications, external factors, or underlying diseases. </li></ul>

<ul><li>Prophylactic medication, vaccines, and early treatment of airway diseases help in later life.</li></ul>

<ul><li>Autoimmune diseases–arthritis, thyroid, etc.- where the body's defense mechanism has become rogue and fights itself, can develop from childhood till late in life.</li></ul>

<ul><li>Accidents – happen at any age, damaging the breathing apparatus and requiring emergency treatment </li></ul>

<ul><li>Cancer in any part of the body, including radiation, may affect the lungs at any age</li></ul>

<ul><li>Body’s failure of in-built Immunity (innate) or acquired immunity mechanism; sunlight is nature’s gift to mankind; it improves lung resistance at all ages</li></ul>

<ul><li>Snoring as an indicator for suspected obstructive sleep apnea </li></ul>

<ul><li>Exercise – yoga, sports, walking, physical and breathing exercises help to improve the performance of the respiratory tract throughout life</li></ul>

<ul><li>Education – helps in understanding the causes, prevention, and timely treatment. It helps in averting damage to the airways in the future. </li></ul>

<ul><li>Availability of health care facilities in urban &amp; rural areas – can make a difference in the development, prevention, and treatment of respiratory disorders. </li></ul>

<ul><li>Breastfeeding of the baby is important as it helps in the development and growth of the lungs, immunity, and fighting against damaging forces in nature, in the form of bacteria, viruses, fungi, prions, and a horde of known and unknown mechanisms which harm airways. Cough and sneeze reflexes begin to develop, which are powerful forces used to throw out unwanted particles and organisms from the airways.</li></ul>

The lungs and airways perform non-respiratory functions of protecting the body against harmful insults, both from within and external threats, and it also protects against insults received from other organs of the body. The lungs have a powerful defense mechanism protecting the body and also have hormonal, physical, and immunological defense mechanisms.
