When sleeplessness starts in the legs
Uncomfortable nighttime leg sensations can spoil your sleep, but you can take steps to relieve it.
Is restless legs syndrome (RLS) the cause of your restless sleep? This exasperating condition triggers abnormal sensations in the legs and an irresistible urge to move them. It can wreak havoc with sleep, leading to daytime fatigue.
Full bladder wakes women more often than thought
Two in three women over age 40 wake up at least once each night because of a full bladder, and nearly half make two or more nighttime trips to the bathroom. But only a quarter of women who get up to urinate during the night say they are bothered by having to do so.
That's the finding from a survey of more than 2,000 northern California women ages 40 and older. Factors that increased the likelihood that a woman woke at night to urinate included older age, past hysterectomy, hot flashes, and use of vaginal estrogen. However, the late-night bathroom breaks weren't caused by an overactive bladder or stress incontinence. The results were published in the January 2015 issue of the journal Obstetrics and Gynecology.
iPad can disrupt sleep, study suggests

Using an iPad or other backlit electronic tablet in the hours before bedtime not only prevents you from falling asleep, it may also affect your alertness the next day, according to a report published in the Proceedings of the National Academy of Sciences, Dec. 22, 2014. Researchers at Harvard-affiliated Brigham and Women's Hospital found that the light emitted by the devices reset the body's circadian clock, which synchronizes the daily rhythm of sleep to daylight. As a result, people reading e-books took longer to fall asleep and were less alert the next morning than when they read print books instead.
During the two-week study, 12 men and women read digital books on an iPad for four hours before bedtime each night for five consecutive nights. They also followed the same routine using printed books. When they read the iPad, participants were less sleepy before bedtime but were less alert the following morning, even after eight hours of sleep.
Poor sleep linked to dementia and ministrokes

Poor sleep is linked to high blood pressure, diabetes, obesity, and heart disease. Now a study published in Neurology Dec. 10, 2014, suggests that people with conditions that rob them of oxygen and deep sleep are more likely to have changes in the brain that may lead to dementia. Researchers say conditions such as emphysema and sleep apnea reduce the amount of oxygen in the blood during sleep, which can lead to silent, undetectable "ministrokes." Researchers also found that people who spend less time in deep sleep, called slow-wave sleep, are more likely to have loss of brain cells than people who spend more time in slow-wave sleep. Slow-wave sleep is important in processing new memories and remembering facts. The researchers noted that past evidence has shown that using a continuous positive airway pressure (CPAP) machine for obstructive sleep apnea may improve cognition, even after dementia has developed. "Sleep quantity and quality are important to maintain optimal health and prevent disease," says sleep expert Dr. Lawrence Epstein, an instructor in medicine at Harvard Medical School. "By getting enough sleep, you ensure that you are getting all the types of sleep, which is necessary to maintain proper functioning."
Gentler exercise for mind and body is best for sleep

Just as regular exercise has a host of health benefits for the body, staying mentally active appears to preserve memory and general sharpness. But for getting a good night's sleep, light workouts for both body and brain may be best, according to a study in the Journal of the American Geriatrics Society.
The study focused on 72 people, ages 67 to 79, who reported poor sleep as well as declining mental sharpness. They were assigned at random to do either strenuous aerobic exercise or a gentler stretching routine, paired with either watching educational DVDs (followed by short quizzes) or engaging in more demanding computer-based brain training.
