Getting six to nine hours of sleep per night is associated with higher ratings
for quality of life and lower ratings for depression, suggests a research abstract that will
be presented Tuesday, June 14, in Minneapolis, Minn., at SLEEP 2011, the 25th
Anniversary Meeting of the Associated Professional Sleep Societies LLC (APSS).
Results show that people with a "normal" sleep duration of six to nine
hours per night had higher self-reported scores for quality of life and lower
scores for depression severity compared to short and long sleepers. These
differences were statistically significant in all comparisons. Among patients
who reported having perfect health, there were a higher percentage of normal
sleepers, who also had significantly lower scores for depression severity
compared to short and long sleepers with perfect health.
"These results
are important because they provide more information about the importance of
getting enough sleep, which is usually six to nine hours per night," said
principal investigator Dr. Charles Bae, neurologist at the Cleveland Clinic
Sleep Disorders Center in Ohio. "People may already expect that their quality of
life could be decreased when they do not get enough sleep, but they may not
realize that sleeping too much can also have a negative impact."
secretion the next day, driven by increased subsequent slow-wave sleep.
Sleep deprivation was found to enhance activity on the
hypothalamic-pituitary-adrenal axis (which controls reactions to stress
and regulates body functions such as digestion, the immune system, mood, sex, or energy usage) while suppressing growth hormones. The results supported previous studies, which observed adrenal insufficiency in idiopathic hypersomnia. Patients with rheumatoid arthritis
and fatigue need to identify the specific causes for their individual
symptoms, so they can be treated more effectively. Being aware of when
the fatigue is at its worst can help patients
identify the causes and provide them with a schedule of when they are
likely to have more energy to complete necessary or desired activities.
We should all get enough sleep and sufficient exercise no matter how demanding our daily lives become.
