United Nations: Some 2.4 billion people — one out of every three inhabitants of the planet — still have no access to sanitation facilities, the World Health Organisation (WHO) and Unicef said on Tuesday.

Of those, 946 million continue to defecate outdoors, a very problematic practice, because in many places it creates a continuous source of disease and pollutes the water supply.

“Until everyone has access to adequate sanitation facilities, the quality of water supplies will be undermined and too many people will continue to die from waterborne and water-related diseases,” said Maria Neira, director of the WHO Department of Public Health, Environmental and Social Determinants of Health.

The UN, which refers to adequate sanitation as an entire system that hygienically separates human excrement from the population, set as one of its Millennium Development Goals the reduction by half of the number of people without access to such a system by 2015.

That means that 77 percent of the world population should now have access to sanitation, a goal that will not be met by some 9 percentage points, or 700 million people.

According to Unicef and WHO, the lack of progress in this area also threatens to undermine child survival and the health benefits that were expected to be achieved by improving access to drinking water, another Millennium Development Goal that, in this case, has fortunately been achieved.(IANS)

Love to drink your tea piping hot? Beware, it could raise the risk of esophageal cancer, finds a study.

The study showed that risk of esophageal cancer more than doubled among those who regularly drank tea at 75 degrees Celsius

However, waiting for at least four minutes before drinking a cup of freshly boiled tea can reduce the risk of the cancer arising from the oesophagus — the food pipe that runs between the throat and the stomach.

“Many people enjoy drinking tea, coffee, or other hot beverages. However, according to our report, drinking very hot tea can increase the risk of esophageal cancer, and it is therefore advisable to wait until hot beverages cool down before drinking,” said lead author Farhad Islami of the American Cancer Society.

The study, published in the International Journal of Cancer, involved 50,045 individuals aged 40 to 75 years.

Drinking 700 ml per day of tea or more at a higher temperature (60 degrees Celsius or higher) was associated with a 90 per cent higher risk of esophageal cancer, the researchers said.

The results could also be extended to coffee, hot chocolate or other hot beverages.
