Yale researchers found that diphenhydramine, a commonly prescribed sedative, increases the risk of delirium symptoms in older hospitalized patients. The study suggests that using diphenhydramine as a routine sleeping aid should be discouraged in older hospitalized patients due to potential harm
A recent outbreak of sleeping sickness in eastern Uganda may be attributed to livestock movement from another part of the country where the disease is endemic. The study found that over 50% of cattle traded at the market originated from areas with the disease, and that distance to the market was a significant risk factor for sleeping s...
Researchers have found that aging rats exhibit fragmented behavioral rhythms, taking naps when they should be active. The study suggests that the suprachiasmatic nucleus (SCN) cells, responsible for regulating circadian rhythms, may be losing their ability to mark time as individuals age.
A study by Harvard Medical School researchers found that sleeping the first night improves task performance and memory consolidation. Despite two additional nights of sleep, those who stayed up all night initially showed no improvement.

Researchers found that the heart's fluctuations in beats are strongly correlated with sleep, showing a fractal pattern on both short and long timescales. This suggests a hitherto unsuspected role for sleep in regulating the heartbeat.
A study led by Charles A. Czeisler found that healthy older adults tend to wake up earlier due to restricted sleep hours relative to their circadian period, similar to younger individuals. The study suggests that age does not inherently shorten the human circadian period.
A study of 510 preschool children found that those sleeping less than 10 hours a day are at risk for increased behavioral problems, such as oppositional behavior and aggression. The relationship between sleep and behavior problems is complex, with possible interaction effects between variables like temperament and parenting.
Researchers found that melatonin reacts with peroxynitrite-derived free radicals, forming compounds similar to brain signaling chemicals. These metabolites could impact aspects of behavior, such as mood, with unclear consequences for human health.
NASA gave astronauts melatonin to improve sleep, but found no benefit; instead, electrodes seemed to help them relax and sleep better. Astronauts' duties likely cause insomnia, and monitoring equipment helps them see sleep as part of their mission.
A team of scientists has discovered a genetic mechanism controlling the inner workings of the biological clock, which also drives bodily rhythms such as temperature, blood pressure, hormones, and sleep-wake cycles. The findings may lead to more efficacious treatments for diseases like heart attacks and asthma.
