A study published in the journal Sleep found that women with restless legs syndrome (RLS) have higher levels of estradiol during pregnancy, which may contribute to the development of RLS symptoms. The study also found that women with RLS experience more periodic limb movements (PLMs) before and after delivery.
A study found that daytime functional impairments in older men with obstructive sleep apnea are largely explained by total sleep time rather than OSA severity. Total sleep time was also associated with measures of sleep disturbances and quality of life.
A study using twin data revealed that genetic factors play a significant role in linking sleep problems to later depression in young children. The stability of sleep problems across time is mainly caused by genetic influences, while non-shared environmental influences dominate the development of depressive symptoms.

A study found that older adults with insomnia are less sensitive to changes in skin temperature, making it harder for them to detect when their body is too hot or cold. Warming the skin can facilitate sleep onset despite this decreased sensitivity.
A study found that older adults who slept more during rehabilitation had less functional recovery and took longer to recover. The study suggests that interventions to improve sleep patterns may promote functional recovery in older adults.
Healthy teens who slept less than 6.5 hours a night were 2.5 times more likely to have elevated blood pressure compared to those who slept longer, with an average increase of 4 mm Hg in systolic blood pressure. The study also found that poor sleep efficiency was associated with higher risk of prehypertension and hypertension.
Circadin, a new drug developed at Tel Aviv University, replenishes the hormone melatonin, which declines with age, to improve sleep quality and morning alertness in people over 55. This therapy has also been shown to normalize blood pressure and blood sugar levels at night.
A study found that older adult dementia caregivers have significantly worse sleep patterns than non-caregivers, with less total sleep time and increased daytime sleepiness. Caregivers also reported lower subjective sleep quality and higher depressive symptom scores.
A study found that sleep plays a key role in preserving emotional memories, strengthening the memory's emotional core while diminishing neutral background details. This process enables the brain to selectively preserve only the most salient information, leading to vivid recall of emotional events.
