Asthma can be defined as condition of lungs that can lead to inflammation or swell ing and soreness of air passages. [1] Asthma and similar allergic ailments are substantially increasing in an alarming rate globally. Westernized countries and countries moving to a westernized lifestyle have greater incidence of asthma when compared with less advanced countries. Although latest scientific studies reveal that the occurrence of asthma is a peak in developed countries, yet there are no explanations available thus far for the same. Scientific studies show the varying situations and the behavioural patterns associated with the so called “westernized” lifestyle are responsible for increase in the frequency of asthmatic attacks amongst general population. As an example, due to upgrading in hygiene and control over infectious diseases, it really is hypothesized that diminutive experience contagious agents during infancy can possibly lead to the development of asthma and allergies. Accordingly, few numerous studies have publicized that experience of markers linked with contagious and infectious agents like endotoxins, farm animals and pets can lessen the possibility of such ailments. Furthermore, another attributes of the westernized lifestyle like Obesity and exposure to allergens have been associated with the development of such disorders. Additionally, dietary changes who have happened over the periods amongst all ages and in special conditions (pregnancy etc.), is the one other significant facets of modern lifestyle which may have contributed to these conditions.

Some of risks attributed by present lifestyle and bringing about Asthma are:

- Obesity

- Smoking

- Diet and Nutrition

- Exercise(exercise induced asthma)

- Medications

- Occupational Exposure

- Stress

- Environmental Exposures: Inside and outside Air pollutants; Allergens

[2,3 and 7]


Obesity or excessive weight is among the major lifestyle diseases. A substantial amount of scientific data reveals that Obesity is a causative factor for Asthma. The info is collected from adults, adolescents and youngsters worldwide and specify an elevated relative risk of asthma in the obese and overweight and express that Obesity predates Asthma. The mechanical basis of this correlation is not yet established. However, depending on scientists viewpoint Obesity and Asthma share common etiology like common genetic predisposition, similar results of in utero conditions, or that obesity and asthma are mutually the end result of certain other predisposing factors such as physical activity or diet.[4]

Moreover, research studies shows that obese patients have an overabundance of severe asthma when compared with normal weight individuals etc severity can be because of greater respiratory inflammation, that is certainly, airway obstruction or it is also due to compact results of asthma drugs or medications in Obese patients. [5]

Such people are advised by physicians to follow along with a strict weight management schedule comprising daily exercise and morning walk so that you can have a healthier lifestyle.

Latest research on enhanced potential for asthma after the commencement of habitual smoking all through upbringing and teenage life corresponds with the substantial data showing that active smoking leads to unpleasant and severe respiratory health effects in adolescents and kids after a brief duration of constant smoking. The fact that teenagers who smoke constantly convey more severe symptoms and lessen lung function within the first couple of years of commencement may be acknowledged by researchers throughout the world. In addition to this, studies have proved that regular or continuous smoking enhances the possibility of asthma and other respiratory disorders knowning that significant long-term effects of smoking aren't just restricted with those developing a history of smoking for several years.

Moreover, recent medical trial studies have established that paternal and maternal smoking (pregnant and breast-feeding mothers who will be regular smokers) can bring about undesired health consequences on new-borns, childrens and adults, making their body at risk of asthma and other severe respiratory tractinfections.

Efficient tobacco control endeavours emphasizing the control and prevention of smoking in children, teenagers, adults, women of childbearing age and expectant women are immediately required to prevent the severe installments of asthma in these people.[6]

Diet and Nutrition

Scientific studies have established a diet rich in marine essential fatty acids, peculiarly fish oil, can have valuable effects on inflammatory conditions like asthma.Also, berry eating can lead remarkable improvement in signs and symptoms of asthma.Though, the influence of dietary salt reduction in the treatment of asthma just isn't yet established by researchers, nevertheless it has been concluded that there is certainly significant improvement in pulmonary function using a low-salt diet. [7]

Exercise Induced Asthma

Exercise-induced asthma is understood to be a state in which smooth muscles of the lungs starts contracting because of physical action. As a result, breathing becomes hard as well as a person physical performance declines inevitably. Exercise-induced asthma is much more common in athletes who perform rigorous exercises as a part of their daily routine. The most typical symptoms of Exercise-induced asthma are: wheezing, difficulty in breathing, chest tightness, coughing and problems with prolonged sessions of exercise.

The more uncommon symptoms include stomach pain, nausea, being unable to exercise in cold, chest congestion/discomfort, frequent colds, dry throat and headache

Proper warm -up or cool-down may prevent or decrease the occurrence of Exercise Induced Asthma.Also, as environmental factors such as cold, dry air, thin air, airborne allergens and food allergens like egg-whites, peanuts, almonds or bananas, two hours before exercise can trigger an Symptoms of asthma, it is highly far better to perform exercises in finest circumstances or conditions characterised by warm, humid weather; negligible a higher level pollutants or allergens; plus a moderate altitude. [8]


Substantial proof of augmented or increased airway resistance is observed in normal individuals and asthamatic patients using medicines like propranolol and aspirin.Similar evidence may be seen in Asthmatic patients using Timolol eye drops for glaucoma.

A few other drugs which are seen to provoke Asthma attack are: Cocaine, Dipyridimole, Hydrocortisone, Interleukin-2, Methylphenidate, Nitrofurantoin, Sulfasalazine, Protamine and Vinca alkaloids.

These drugs should be avoided as much as possible and should not be taken without prior approval or consultation of Physicians.[9]

Occupational Exposure

Present-day Working environment act as an add on to occupational respiratory diseases like Asthma because of inhalation of both organic and inorganic substances. Globally, Asthma could be the prime diseases caused due to inhalation of organic agents. [7]

Commonly related occupations and exposures are: car painting (isocyanates), hairdressing (various chemicals), domestic and commercial cleaning(cleaning solutions), medical professionals(latex) and baking(flour dust), amongst many others.[2]

Avoidance of such substances, particularly for people working in industrialized environment is hard.[7] Thus, private and public sectors should implicate certain health policies, compensative and preventive steps for the well being of their laboured employees, contributing to the overall wellness of their companies.


Stressful life circumstances advances the signs and symptoms of asthma. Studies have demonstrated the fact that concomitant parental and disputes enhances the possibility of Asthma at an early age, at the much higher rate in comparison with other risk factors like parental asthma, education and passive smoking.[10].

Moreover, recent clinical findings have enumerated an array of emotional states as probable precursors of asthmatic symptoms. It had been confirmed that distinct affective states like sadness or depression are predominantly related to an exasperation of sign and symptoms in individuals with asthma. Correspondingly, latest clinical trials have revealed that variant emotional and affective states such as anxiety, anger, and joy are similarly competent at eliciting increases in airway resistance in asthmatics. [11]

Environmental Exposures

Inside and outside Air Pollutants:

Indoor Air Pollutants, basically indoor allergens, nitrogen dioxide, formaldehyde, chemical toxins, indoor generated particles and dangerous can influence the respiratory system and can cause or aggravate the outward symptoms of asthma.

Similarly, long-term contact with combustion related fine particulate air pollution is another significant environmental risk factor for respiratory diseases like asthma.

Here again, relative efforts are essental to government and local public in general to combat the indoor and outdoor pollution by adopting fitness. [7]


Both indoor allergens like mites, some moulds, animal danders and insects and outdoor allergens like pollens and fungal moulds are normally found to exacerbate the signs and symptoms of asthma and other respiratory disorders. Physicians recommend proper adoption of preventive control measures by average man or woman to diminish the harmful affects of allergens on sensitive lungs.[7]


Asthma serves as a condition of lungs that may result in inflammation or swelling and soreness of airways. Obesity, Smoking, Diet and Nutrition, Exercise (exercise induced asthma), Medications, Occupational Exposure, Stress and Environmental Exposures: Inside and outside Air pollutants; Allergens are among the major risk factors attributed by current modernized lifestyle that are responsible for causing or alleviating the outward symptoms of Asthma. By adopting a healthier lifestyle, consisting of proper diet and resisting to harmful habits of smoking and rehearse of undesired medications may help in combating the severe signs and symptoms of Asthma. Furthermore, a leading role is required by government and sectors as well as by a common man to relieve the detrimental effects of indoor and outdoor air pollution as well as the occupational and emotional stress; on sensitized lungs of a normal human-being.
