    More Than 8 Hours Sleep Too Much of a Good Thing
    Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
    Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night.People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers.
    These findings, which DL Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night’s rest may not need to set aside。more than 8 hours a night.He added that“it might be a good idea'’for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this.
    Previous studies have shown the potential dangers of chronic shortages of sleep一for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
    For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionnaires,in which participants indicated how much they slept during the Week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
    KriDke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed.As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake.”he said.

    Study says dogs can smell cancer
    Dogs are known for their sense of smell. They can find missing people and things like bombs and illegal drugs. Now a study suggests that the animal known as man’s best friend can even find bladder cancer.
    Cancer cells are thought to produce chemicals with unusual odors. Researchers think dogs have the ability to smell these odors, even in very small amounts, in urine. The sense of smell in dogs is thousands of times better than in humans.
    The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner. The mole was later found to be skin cancer.
    Carolyn Willis led a team of researchers at Amersham Hospital in England. They trained different kinds of dogs for the experiment. The study involved urine collected from bladder cancer patients, from people with other diseases and from healthy people.
    Each dog was tested eight times. In each test there were samples for the dogs to smell. The dog was supposed to signal the one from a bladder cancer patient by lying down next to it.
    Two cocker spaniels were correct fifty-six percent of the time. But the scientists reported an average success rate of forty-one percent.
    As a group, the study found that the dogs chose the correct sample twenty-two out of fifty-four times. That is almost three times more often than would be expected by chance alone.
    The British Medical Journal published the research. In all, thirty-six bladder cancer patients and one hundred eight other people took part.
    During training, all the dogs reportedly even identified a cancer in a person who had tested healthy before the study. Doctors found a growth on the person’s right kidney.
    Baldder cancer is the ninth most common cancer worldwide. The International Agency for Research on Cancer says this disease kills more than one hundred thousand people each year. Doctors say cigarette smoking is the leading cause of bladder cancer.
