Obesity linked to quantity of sleep!

P eople who sleep fewer than six hours a night - or more than nine - are more likely to be obese, according to a new US study that is one of the largest to show a link between irregular sleep and big bellies. The study also linked light sleepers to higher smoking rates, less physical activity and more alcohol use. The research adds weight to a stream of studies that have found obesity and other health problems in those who don't get proper shuteye, said Dr Ron Kramer, a Colorado physician and a spokesman for the American Academy of Sleep Medicine. "The data is all coming together that short sleepers and long sleepers don't do so well," Kramer said. The study is based on door-to-door surveys of 87,000 US adults from 2004 through 2006 conducted by the National Centre for Health Statistics, part of the Centers for Disease Control and Prevention. Such surveys can't prove cause-effect relationships, so - for example - it's not clear if smoking causes sleeplessn...

Why Disasters Are Getting Worse?

By: AMANDA RIPLEY Thu Sep 4, 12:40 PM ET In the space of two weeks, Hurricane Gustav has caused an estimated $3 billion in losses in the U.S. and killed about 110 people in the U.S. and the Caribbean, catastrophic floods in northern India have left a million people homeless, and a 6.2-magnitude earthquake has rocked China's southwest, smashing over 400,000 homes. If it seems like disasters are getting more common, it's because they are. But some disasters do seem to be affecting us worse - and not for the reasons you may think. Floods and storms have led to most of the excess damage. The number of flood and storm disasters has gone up by 7.4% every year in recent decades, according to the Centre for Research on the Epidemiology of Disasters. (Between 2000 and 2007, the growth was even faster - with an average annual rate of increase of 8.4%.) Of the total 197 million people affected by disasters in 2007, 164 million were affected by floods. It is tempting to look at the line-u...

Soy Products Can Reduce Sperm Counts!

By: Heather Hajek Published: Friday, 25 July 2008 www.healthnews.com C alling all men who want to become fathers! Soy products may reduce a man's sperm count. Based on a recent study, men who consume soy products may have lower sperm counts than those who don't. The study was based on a small group of men who visited the Massachusetts General Hospital Fertility Center from 2000 to 2006. Even though the study found that some of the men who ate soy products on a regular basis had lower sperm counts, the researchers conducting the study are not saying that soy products were the cause of the lower sperm concentrations. The men who had soy products in their diets recorded lower sperm counts than those that didn't, but their counts were still within the normal range. Researchers don't deny that during the study men who consumed soy products had lower sperm counts, but they want people to realize there are other factors other than soy products that may have played a role in th...
