Stable
marriage is linked with better sleep in women
Being stably married or gaining a partner is associated with
better sleep in women than being unmarried or losing a
partner, according to a research abstract presented at SLEEP
2009, the 23rd Annual Meeting of the Associated Professional
Sleep Societies.
According to the study's lead author, Wendy Troxel, PhD,
Assistant Professor at the University of Pittsburgh School
of Medicine, women who were stably married had the highest
quality sleep measured objectively and subjectively, and
these results persisted even after controlling for other
known risk factors for sleep, including age, ethnicity,
socioeconomic status, and depressive symptoms.
Troxel presented related findings at SLEEP 2008, showing
that marital happiness may lower the risk of sleep problems
in women, while marital strife may heighten the risk. "The
current findings dovetail with our previous work, suggesting
that relationship stability as well as quality may be
important protective factors for women's sleep," said Dr.
Troxel.

Poor sleep is associated with lower relationship
satisfaction in both women and men
A bidirectional association exists between couples' sleep
quality and the quality of their relationship.
Results indicate that on a day to day basis, couples'
relationship quality affects their sleep, and their sleep
also affects their subsequent relationship functioning. For
men, better sleep (as indicated by diary–based sleep
efficiency) was associated with more positive ratings of
relationship quality the next day. For women, negative
partner interactions during the day were associated with
poorer sleep efficiency for both themselves and their
partner that night.
Hasler said that interventions directed at improving either
quality of sleep or relationships may provide overall
benefits, as the two directly impact each other. Hasler
recommends that couples should resolve disputes before going
to bed and avoid confrontational discussions on a day when
one or both of them had a bad night's sleep.

Study shows a bidirectional relationship between chronic
stress and sleep problems
People with chronic stress report shorter sleep duration,
worse sleep quality, and more daytime functioning
impairments. Conversely, daytime functioning impairments and
shorter sleep duration demonstrated a predictive
relationship with habitual stress complaints.
Results indicate that poor sleep may be a potential cause of
stress; individuals who report more fatigue and less total
sleep are more likely to report more stress.
According to principal investigator Eric Powell, PhD,
director of research at the Research Center at Clayton Sleep
Institute in St. Louis, Mo., factors that were the best
predictors of high stress were daytime functioning and
typical amount of sleep.
"The simplest, and likely best advice for individuals with
high stress and poor sleep is to look at some of the
lifestyle choices they are making and ensuring sufficient
sleep is at the core of those choices," said Powell.

Better sleep is associated with improved academic success
Getting more high-quality sleep is associated with better
academic performance. The positive relationship is
especially relevant to performance in math.
Results indicate that higher math scores were related to
greater sleep quality, less awakenings and increased sleep
efficiency. Higher English and history scores were
associated with less difficulty awakening. Increased
sleep-onset latency over the weekend was associated with
worse academic performance.
According to principal investigator Jennifer C. Cousins,
PhD, postdoctoral fellow at the University of Pittsburgh
Medical Center, it was surprising that although more and
better sleep produced overall improvements, different types
of sleep measures were related to different types of
functioning.
"Sleep deficits cause problems for adolescents, but students
differ in their personal resources and in how chaotic their
sleep-wake schedules are," said Cousins. "The more regular
and predictable their sleep is, the better they are likely
to do when confronted with short-term sleep deficits.
Therefore, participants with better sleep overall may be
affected differently in a sleep condition compared to those
who have a more varying sleep/wake schedule."

Meditation may be an effective treatment for insomnia
Meditation may be an effective behavioral intervention in
the treatment of insomnia.
Results indicate that patients saw improvements in
subjective sleep quality and sleep diary parameters while
practicing meditation. Sleep latency, total sleep time,
total wake time, wake after sleep onset, sleep efficiency,
sleep quality and depression improved in patients who used
meditation.
According to principal investigator Ramadevi Gourineni, MD,
director of the insomnia program at Northwestern Memorial
Hospital in Evanston, Ill., insomnia is believed to be a
24-hour problem of hyperarousal, and elevated measures of
arousals are seen throughout the day.
"Results of the study show that teaching deep relaxation
techniques during the daytime can help improve sleep at
night," said Gourineni.

Rheumatoid arthritis is associated with poor sleep in

Symptoms of rheumatoid arthritis (RA) negatively affect
women's sleep. Sleep is further impaired by pain, depression
and poor adherence to RA medications.

Sleep may be
important in regulating emotional responses
sleep selectively preservers memories that are emotionally
salient and relevant to future goals when sleep follows soon
after learning. Effects persist for as long as four months
after the memory is created.
According to lead author, Jessica Payne, PhD, of Harvard
Medical School in Boston MA, It was surprising that in
addition to seeing the enhancement of negative memories over
neutral scenes, there was also selectivity within the
emotional scenes themselves, with sleep only consolidating
what is most relevant, adaptive and useful about the scenes.
It was even more surprising that this selectivity lasted for
a full day and even months later if sleep came soon after
learning.
