Researchers discovered that 67% of those with TBI suffered from excessive daytime sleepiness compared to 19% of healthy individuals.
A review of 21 studies on dietary interventions and sleep found significant effects in nearly half of the laboratory-based studies. However, overall findings suggest that a single diet change is unlikely to drastically improve sleep quality for most people.
Researchers discovered that when people sleep in an unfamiliar place, one hemisphere of the brain stays more awake to keep watch. This phenomenon is related to the difficulty a person experiences in falling asleep and can be reduced by bringing familiar comforts.
A study found that teenage mothers in Colorado were aware of safe sleep guidelines but chose to disregard them due to misconceptions about infant comfort and safety. The researchers suggest innovative public service announcements and improved healthcare provider communication could improve safe sleep behaviors among this high-risk group.
A new study published in Nutrients found that high-fat diets are associated with increased risk of daytime sleepiness and poor sleep quality in Australian men. The research, which analyzed data from over 1,800 men aged 35-80, also linked high fat intake to a higher incidence of sleep apnea.
Researchers at Umea University have discovered an enzyme in the sleeping sickness parasite that can cleave and disarm adenosine analogue pharmaceuticals. This breakthrough enables the development of more efficient drugs, bypassing the parasite's protective mechanism.

A new study reveals a significant link between nightmares and suicidal behaviors, with nightmares acting as a stressor in individuals with post-traumatic stress disorder (PTSD). The study found that 62% of participants who experienced nightmares reported suicidal thoughts, plans, or attempts, compared to 20% without nightmares.
Researchers found that sleep is poor in patients with chronic stroke, but knowledge on this topic is lacking. A comprehensive understanding of sleep is needed to improve rehabilitation effectiveness and ensure quality long-term care.
