A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off-if it is milked from a cow at night.
Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.
The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.
Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.
Night milk quickened the start of sleep and caused the mice to sleep longer.
While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.
Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.
Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

Traffic problems are an everyday concern in many cities, including Washington, D. C. A growing number of Washingtonians are turning to bicycles to get to and from work. In fact, the number of commuters who use bicycles has doubled in the city since 2007.
Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University，popularly known as Virginia Tech. He has written a book about urban biking, called City Cycling. He says there is a reason why urban bike tiding is now becoming more popular.
“Over the last 60 to 70 years, cities in America have been adapted to the automobile.”
“Most cities took advantage of the money coming for the interstate (洲际)highway system, from the federal government, starting in 1956. There was a 90 percent federal match(补贴)so the cities only had to put up 10%. It was very tempting.(临时的).”
In the years after World War Two, many Americans moved to suburban communities, just outside major cities, They decided to travel great distances to and from work in exchange for a home in the suburbs. Their cars became a symbol of freedom.
But today, many people believe they can save money by living in the city.
Greg Billing is with the Washington Area Bicyclist Association. “When a person makes a change from using a car to using a bike, he/she is saving anywhere between 8 or$9,000 a year.”
Ralph Buehler says governments save money when people use bicycles. “Building bicycling facilities(设施) is much cheaper than building and maintaining road facilities or public transport.”
Washington, D.C has also taken steps to protect bike riders. It approved a safe passing law and created areas on the road between cars and bikes.
The United States Census Bureau says 4% of the city’s workers ride to work by bike. The only city on the East Coast with more bike commuters is New York.
