As you drift into unconsciousness before a surgery, general anesthetic drugs flowing through your blood are putting you to sleep by binding mainly to a protein in the brain called the ɣ-aminobutyric acid type A (GABAA) receptor. Now UT Southwestern scientists have shown exactly how anesthetics attach to the GABAA receptor and alter its three-dimensional structure, and how the brain can tell the difference between anesthetics and the psychoactive drugs known as benzodiazepines – which also bind to the GABAA receptor. The findings were published online today in the journal Nature.

Getting more sleep, and establishing a regular sleep schedule, is a common recommendation for maintaining and improving health, including for people with Type 1 diabetes. Short sleep patterns may affect how the body uses insulin, and irregular sleep schedules can affect glucose through changes in one's circadian rhythm or biological clock.

Disturbed sleep patterns do not cause Alzheimer’s disease but people who are at high genetic risk of developing Alzheimer’s disease may be more likely to be a “morning person,” have shorter sleep duration and other measures of sleep disturbance and are less likely to have insomnia. The study is published in the August 19, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Whether children have ongoing sleep problems from birth through childhood or do not develop sleep problems until they begin school, a new study by researchers at Children’s Hospital of Philadelphia (CHOP) has found that sleep disturbances at any age are associated with diminished well-being by the time the children are 10 or 11 years old. The findings, which were published in The Journal of Child Psychology and Psychiatry, suggest health care providers should screen children for sleep problems at every age and intervene early when a sleep problem is identified.

The COVID19 pandemic is creating unprecedented levels of sleep deprivation, presenting a significant risk to our mental and physical health. Now, a new randomized controlled cross-over pilot trial published online today in Neurophysiology explains that high doses of hydrogen-rich water (HRW) are just as effective as caffeine in raising alertness in sleep deprived men and women. Importantly, this research is the first of its kind to show that hydrogen water and caffeine had an impact on different domains of alertness. Specifically, the study results demonstrate that; hydrogen improves orienting to sensory stimulation, while caffeine alters awareness and executive attention that refers to the ability to control our attention and ongoing cognitive processes, including thoughts and feelings.

The uncertainty and fear associated with the COVID-19 virus is causing many Americans to have difficulty falling asleep and staying asleep, and yet a good night’s sleep has never been more important. “Now more than ever, we need to get good sleep,” said Loyola Medicine pulmonologist Amy Guralnick, MD. “Sleep can help our immune system function at its best. Getting a good night’s sleep also helps us to think clearly and to problem-solve better. Additionally, having adequate sleep helps our mental health, as a lack of sleep is linked with depression, anxiety and other mental health conditions.”
