An article in ScienceDaily for June 30, 2008 reported on an effect of inadequate sleep.
The findings suggest that inadequate sleep in the elderly, who normally experience sleep disturbances, could exacerbate an already-impaired protective response to protein misfolding that happens in aging cells. "Protein misfolding and aggregation is associated with many diseases like Alzheimer's and Parkinson's," notes first author Nirinjini Naidoo, PhD, Assistant Professor in the Division of Sleep Medicine.

An acute session of moderate aerobic exercise, but not heavy aerobic or moderate strength exercises, can reduce the anxiety state and improve the sleep quality of insomnia patients, according to a research abstract that will be presented on June 11 at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
ScienceDaily for June 10, 2008 reported on behavioral problems affected by lack of sleep.
Insufficient sleep among adolescents may not only contribute to lower grades and a lack of motivation, but may also increase the odds of serious levels of emotional and behavioral disturbances, including ADHD, according to a research abstract that will be presented on June 9 at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).
An article in ScienceDaily for June 11, 2008 reported on marital happiness and problems with sleeping.
The study, authored by Wendy M. Troxel, PhD of the University of Pittsburgh, focused on 1938 married women from the Study of Women's Health Across the Nation, a multi-site study of mid-life women, with an average age of 46 years. Out of the study participants, 51 percent were Caucasian, 20 percent African-American, 9 percent Hispanic, nine percent Chinese, and 11 percent Japanese. The subjects reported their marital happiness, sleep quality and frequency of difficulty falling asleep, staying asleep or early morning awakenings.
ScienceDaily for June 9, 2008 reported on effects of insufficient sleep.
The study, authored by Rebecca A. Bernert, of Florida State University, focused on 322 college undergraduates between 19-24 years of age. The following symptom measures were administered: Pittsburgh Sleep Quality Index (PSQI); Insomnia Severity Index (ISI); Beck Depression Inventory (BDI); and Beck Scale for Suicide Ideation (BSS).
ScienceDaily for June 10, 2008 reported on the effect of more sleep on Stanford University swimmers.
Participants in this ongoing study were five healthy students on the Stanford University men’s and women’s swimming teams. For the first two weeks of the study, the students maintained their usual sleep-wake pattern. The athletes then extended their sleep to 10 hours per day for six to seven weeks.
According to the results, when compared to subjects with restricted use of cell phones, young people with excessive use of cell phones (both talking and text messaging) have increased restlessness with more careless lifestyles, more consumption of stimulating beverages, difficulty in falling asleep and disrupted sleep, and more susceptibility to stress and fatigue. They behave more like larks than owls, suggesting a delayed biological clock.
A study reported in ScienceDaily for May 13, 2008 discussed sleep problems and college students.
College students are among the most sleep-deprived age group in the U.S. Sleep deprivation can have detrimental effects on daily performance, including academics and driving, and has also been linked to depressed mood and behavioral problems.
ScienceDaily for June 13, 2007 reported on the impact of lack-of-sleep and growth of speech abilities.
Research examining the impact of sleep in school-age children suggests that even mild sleep loss produces marked deficits in their cognitive development and functioning. Sleep restriction can alter children's initial stages of speech perception, which could contribute to disruptions in cognitive and linguistic functioning -- skills necessary for reading and language development and comprehension, according to recent research.
Parents who want their babies to sleep through the night would be wise to avoid co-sleeping arrangements or feeding their children evening snacks beyond early infancy. According to a Université de Montréal study the way parents put their babies to bed has a direct impact on how well children sleep when they reach four to six years old.

An article in ScienceDaily for April 10, 2008 reported on a link betwen inadequate sleep and behavioral problems later in life.
"Sleep problems are risk indicators of later emotional difficulties in childhood and adolescence and in adulthood," according to background information in the article.

An article in ScienceDaily for April 8, 2008 reported on the need for sleep in babies.
Infants and toddlers who sleep less than 12 hours a day are twice as likely to become overweight by age 3 than children who sleep longer. In addition, high levels of television viewing combined with less sleep elevates the risk, so that children who sleep less than 12 hours and who view two or more hours of television per day have a 16 percent chance of becoming overweight by age 3.

ScienceDaily for March 11, 2008 reported that
Their study, appearing online in the journal Brain, Behavior and Immunity, found that poor sleep is associated with greater psychological distress and higher levels of biomarkers associated with elevated risk of heart disease and type 2 diabetes. They also found that these associations are significantly stronger in women than in men.

Meanwhile, the time switch could shake up your biological clock, rattle your mood and give your bones and teeth an extra dose of vitamin D....
Light is the key to cuing up the internal clock. For instance, sunrise directs the body to release various "wakeful" hormones, which boost metabolism, blood pressure and body temperature. Sunset tells the body it's time to wind down and sleep.
