1. Theme – Life & Living


Globalization is an ultra modern term which is spreading its aura in every corner of the world, so it takes India also in consideration. For a country to become developed and achieve higher standards of success, it is of great significance. This widespread of the spirit of globalization is also affecting the style of working, which ultimately affects the health of the country. Since most of the working population of the country is youth, it is indirectly affecting the future of the country. Awareness about such consequences can lead to their prevention and it is a well known fact that “Prevention is always better than cure”.

India is sitting on the cradle of progress. With massive change in economic policy of Liberalisation, Privatization and Globalization in 1991, India has moved on the path towards modernisation and great technical and professional advancements. There has been a tremendous growth of private sector enterprises in our country and a rise in number of school and college going educated youth who are employed in these sectors.

A survey on willingness of the people to live a long life reveals following result:

India’s youth force is highest in the world, which is extremely determined, ambitious, tech-savvy and confident. The youth vigour is seen as the prime agent for contributing to the country’s economic intensification and development. Youngsters are employed in large number in BPO (Business process Outsourcing), IT and KPO (Knowledge Process Outsourcing) industries, and are being provided handsome salaries. The most striking feature about India’s youth is its desire to stay ahead in the rat race of cut-throat competition, and to succeed as fast as possible. 

But this picture of ‘India shining’ comes at a cost and studies reveal that this cost has to be paid by none other than the very factor that is bringing the country to the brink of high growth, prosperity and development. Majority of college-going students and young working population is concentrated in metropolitan cities, Delhi, Mumbai, Bangalore, Chennai and Kolkata and the urban cities like Pune,

Ahmedabad, Hyderabad, Surat, Kochi, Kanpur, Indore etc. Rapid urbanisation, growth of professionalism and the desire to earn fast and more money, has proved extremely detrimental to the country’s youth. Despite the growth in industry and commerce, the foremost and important sector, neglected in the process, is health.

It is observed that there has been a significant difference in lifestyle of urban young population compared to the traditional, rather ‘disciplined’ style of living. It is seen that the life style adopted by majority of youth is extremely disorganised and unhealthy, and is further coupled with a defective diet. This can be owed to the idea that time is converted to money, and corporate and personal ambitions are being kept over and above health priorities.

Employers have fixed long hours of working for their people, in the way it suits them and young employees are constantly engaged in monotonous and immobile practice of spending hours in front of computer screen, working. They do not realise that even though they may be progressing financially and seem to be securing their lives and their family’s future, they are moving towards an even more insecure future, as they are becoming more vulnerable to serious health risks. It is very unfortunate that they are not conscious about the facts that smoking, consuming calorie rich fast food, alcoholism and drug consumption and eventually becoming couch potatoes while not at work or engaged in anything, will, at the end of the day, cut their life span and hinder the country’s progress at large.

Today our eating habits are different from those of a generation ago in all ways. Fast food, takeaways and eating out are parts of life for modern teenagers. There are many changes during adolescence that can cause changes in eating behaviour. It can be very difficult for parents of teenagers to convince their children about the benefits of healthier eating when they are also competing with the powerful messages advertising the taste of unhealthy but enticing food. Innumerable health issues, which are coming up among today’s youth, show a growing concern among the medicos and health experts. Usually, such issues are attributed to conflicts prevailing in the country over the last 24-25 years.

Sedentary, deskbound life styles and less physical activity are other contributing factors to it. “Change in dietary habits, obesity (which is rapid nowadays due to sedentary life style), less outside activity and more time spend on social websites are the contributing factors responsible for health issues among youth” says Dr. Aadil Ashraf, senior post graduate, Deptt. of medicines, Shri Maharaja Hari Singh (SMHS) hospital in Kashmir. Common problems which arise due to today’s life style are: Obesity, a very common problem, arising due to change in life-style In modern living, there is very limited physical activity, which does not require a dense, calorie rich food but this is the kind of diet which teenagers are normally taking that leads to increase in their weight.

Obesity leads to other problems, like young people start to fight to control the weight, which further leads to diet related disorders like Anorexia, which is more than just a problem because of or with the food. It is a way of using food or starving oneself to feel more in control of life and to effortlessly ease tension, stress, anger and anxiety.

Bulimia nervosa is a disorder in the eating disorder range or spectrum. It is a characteristic disorder of binge eating and characterized by episodes of overeating and then hiding this habit from others and feeling ashamed of. Bulimia is characterized by episodes of secretive, undueexcessive eating followed by inappropriate methods of weight control, such as self induced vomiting, abuse or misuse of laxatives and diuretics or excessive, self planned, self directedexercise. It is a psychological disorder. This is another condition that goes beyond control dieting. The cycle of overeating and purging becomes an obsession similar to an addiction to drugs or other substances. This disorder generally occurs after a number of unsuccessful attempts of dieting. Binge Have you seen any couch potato around you?
