  • Pay to breathe? ‘Oxygen bars’ hit New Delhi as India chokes under pollution & declares health emergency

    Pay to breathe? ‘Oxygen bars’ hit New Delhi as India chokes under pollution & declares health emergency

    A new fad sweeping India offers customers a breath of fresh air… literally. As pollution in New Delhi hits toxic levels, “oxygen bars” are popping up in the city to help locals breathe easy, but some found the idea off-putting.
    New Delhi officials were recently forced to declare a public health emergency over the city’s hazardous air quality after pollution levels soared to around 20 times what the World Health Organization deems safe, halting construction projects, and closing schools across the capital. While the smog-filled air is inescapable for many, those with the cash may find a brief reprieve at their local oxygen bar.

    $4 for 15 minutes of FRESH AIR at oxygen bar to escape air pollution in #Indiapic.

    One such establishment, dubbed Oxy Pure, is tucked away in the corner of an upscale shopping mall, with bright lights and gadgets glowing through its clear glass storefront. Here, customers can pay between 299 and 499 rupees (around $4 to $7) for a 15-minute oxygen session, with their choice of several fragrances: orange, lavender, cinnamon, eucalyptus, lemongrass or peppermint.

    Delhi: An oxygen bar in Saket, ‘Oxy Pure’ is offering pure oxygen to its customers in seven different aromas (lemongrass, orange, cinnamon, spearmint, peppermint, eucalyptus, & lavender), at a time when Air Quality Index (AQI) in the city is in ‘severe’ category.

    “Air pollution is going to dangerous levels so people are coming here to breathe pure oxygen,” Oxy Pure owner Aryavir Kumar told the National.

    Each winter, air quality suffers in cities around India as winds die down and farmers burn the remnants of crops to make room for the next harvest. This time around, Kumar says New Delhi’s worsening smog has driven a surge of business at his establishment.
    “We would get 15-20 people a day [before]. Now we are getting 30-40 customers every day,” he said. “There is a tremendous increase in the numbers of customers in the last two weeks.”

    Conjuring images of a pulmonary ward, the bars deliver O2 through a standard cannula device which customers hook up to their nostrils, cranked out of a “concentrator” machine that pulls clean oxygen out of the polluted air. While Kumar is careful to insist the “oxygen therapy” does not cure any diseases, he says the air can rejuvenate “like a spa.”

    Oxygen bars are not all that uncommon.

    It offers a ‘natural high.’ We’re not used to breathing air which is > 20% oxygen. So, when you take a hit of oxygen at an oxygen bar, you immediately start to saturate your blood with oxygen, which can heighten concentration.

    Despite the potential for benefits, many online found the concept downright dystopian, suggesting a future in which only the wealthy can afford to breathe non-toxic air.

  • Reversible sterilization? India fights back against overpopulation

    Many view India’s ballooning population –set to overtake China’s by the next decade– as a ticking time-bomb, but a solution is now at hand that, nevertheless, has taken four long decades to see the light of day.

    India had only 54 million on its population chart in 1979 when a slight professor in his 40s, Dr Sujoy Kumar Guha, published his first scientific paper on Risug, a molecular drug he had developed as a reversible contraceptive for men.

    He pleaded for clinical trials. But the ‘Doctor’ in front of his name was not from a medical degree; it was courtesy of his PhD studies at an American university. No go, said India’s supreme medical body, the ICMR (Indian Council of Medical Research).

    Guha chose to circumvent this closed door by opting to sit his medical entrance test and by becoming a qualified medical doctor. The ICMR relented and the clinical trials began, but more than a decade had passed and Guha was now in his 50s, an age when most men tend to get somewhat flaccid of mind.

    Phase One of the clinical trials progressed from rats to rabbits to monkeys and then to humans, and proved spectacularly successful in 1993. But then the ICMR brought them to a halt, after someone complained that certain components of Risug are known to cause cancer.

    Guha argued that these individual substances become harmless as compounds, just as chlorine, which could melt human flesh, becomes basic everyday salt when mixed with sodium. The ICMR wasn’t convinced.

    Dr Guha then knocked on the doors of the Supreme Court; Phase Two was set in motion after a few years and, by 2002, Dr Guha’s dreams were close to being realized, before another spanner was thrown in the works.

    This time, it was changes to the international norms for clinical trials. It took the Indian medical authorities another five years to put these required norms in place.

    The envy that took its toll

    Unsurprisingly, Guha’s work evoked interest and envy in equal measure around the world. Peers began sniffing around his wonder drug, and not always with a sense of appreciation. The National Institutes of Health in the US raised questions, causing more delays.

    Dr Guha believes to this day that this was meant to promote a pill-in-the-making which, unlike his one-time injectable hormone-based drug, promised a continual demand and endless profits.

    Now, after another dozen years and nearly four decades all told, Dr Guha’s dream is close to becoming a reality. Extended tests on Risug have shown no side-effects. The Indian medical authorities are hopeful of introducing his reversible contraceptive to the market in the next six to seven months. It would be the first injectable male contraceptive in the world. Its competitor, the pill, is nowhere in sight.

    Indian men prefer to use condoms rather than invasive vasectomy surgery to sterilize their reproductive systems. But Dr Guha’s invention is external, non-invasive and cheap, and could prompt millions to opt for it, given it’s reversible with just two counter injections. There are no barriers to physical intimacy, as with condoms.

    Youth and the shackles of population

    There’s a great imbalance in India’s population trajectory, with southern states meeting the global trends of less than two children per household. In contrast, families in the northern states, home to 40 per cent of India’s population, tend to have nearly four children per household.

    Education, the economic dependence of women and a rural-urban divide all play roles in India’s population, which is bursting at the seams and poses a great strain on the country’s diminishing resources, such as water and energy. India has more than 600 million young people and needs 12 million jobs for them each year. Population is an issue which can no longer be put off till tomorrow.

    In times gone by, around the time when Dr Guha had worked out his invention, Sanjay Gandhi, son of India’s then-reigning prime minister Indira Gandhi, opted for a compulsory sterilization programme to halt the population boom in 1976. Over six million men were sterilized in just a year. Nearly 2,000 men died because of botched operations.

    In the ensuing elections, India voted the Gandhis out of power. Nobody in authority has dared to do anything as dramatic as this since those dark days.

    Dr Guha, nearing 80 and still sprightly, could finally give India a solution to a problem which has seriously shackled the nation’s future. He won’t meet the tragic fate of Dr Subhas Mukherjee, who was the real architect of ‘test-tube baby’ procedure but lost the rights of invention to Louise Brown only because his work hadn’t appeared in any international journal. In 1981, Dr Mukherjee was found hanged in his Kolkata apartment.

  • India to build 100 new airports in decade as domestic air travel demand soars

    The number of operating airports in India is expected to double in the next decade as the government races to meet the growing demand of the country’s aviation market.

    Civil Aviation Minister Suresh Prabhu said on Tuesday that as many as 100 new airports would be built in the next 10 to 15 years for about $60 billion. The airports will be constructed through public-private partnership, he explained.

    According to the ministry, about 70 of the new airports will be constructed in areas that have no such infrastructure. The remainder will become secondary airports that are intended to deal with a sudden growth in demand for air travel that threatens to overwhelm the present infrastructure. At the moment, the country, which is the world’s fastest growing aviation market, has 100 airports.

    Data from the International Air Transport Association (IATA) showed that India’s domestic air demand was highest amongst major aviation markets like Australia, Brazil, China, Japan, Russia, and the US. The country’s domestic passenger traffic grew by almost 18 percent in January.

    In 2017, domestic passenger traffic recorded its 42nd straight month of double-digit growth.

    IATA has predicted that by 2025, India will surpass the UK to become the third largest market for aviation in the world, behind China and the US.
