Insomnia can cause problems during the day, such as excessive sleepiness, fatigue, trouble thinking clearly or staying focused, or feeling depressed or irritable. It is not defined by the number of hours you sleep every night. Although the amount of sleep a person needs varies, most people need between 7 and 8 hours of sleep a night.
Tiny microbes belching toxic gas helped cause -; and prolong -; the biggest mass extinction in Earth's history, a new study suggests.
Children with a devastating genetic disorder characterized by severe motor disability and developmental delay have experienced sometimes dramatic improvements in a gene therapy trial launched at UCSF Benioff Children's Hospitals.
In a paper published by the Journal of Sleep Research, researchers reveal how they examined data* from half a million middle-aged UK participants asked if they had trouble falling asleep at night or woke up in the middle of the night.
Researchers have discovered a possible connection between increased vulnerability to COVID-19 infection and exposure to organophosphate pesticides.
A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.
How often a person takes daytime naps, if at all, is partly regulated by their genes, according to new research led by investigators at Massachusetts General Hospital (MGH) and published in Nature Communications.
Tetrahydroisoquinolines (THIQ) are organic compounds, whose structure includes a benzene ring merged with a nitrogen-containing cycle.
As wind power generation becomes more important, experts in Australia are examining whether wind 'farm' turbine background noise in the environmental can affect sleep and wellbeing of nearby residents.
Immediate actions are needed to limit the greenhouse gas emissions that are driving climate change that helps fuel wildfires, a Monash University study says.
Scientists at Scripps Research have comprehensively mapped how a key class of proteins within cells regulates signals coming in from cell surface receptors.
Scientists at Cold Spring Harbor Laboratory and Stanford University have pinpointed the circuit in the brain that is responsible for sleepless nights in times of stress--and it turns out that circuit does more than make you toss and turn.
A researcher at the IMT School for Advanced Studies Lucca, Giulio Bernardi, has been awarded a European Research Council (ERC) Starting grant, a competitive source of financing attributed to young researchers who pursue innovative research ideas.
Do you have what is known as problematic alcohol use? Then statistically you will also be particularly genetically predisposed to develop e.g. depression and insomnia. And to become dependent on drugs and tobacco. This is shown by a new international study in which researchers from iPSYCH are involved.
Emotional, social and psychiatric problems in children and adolescents have been linked to higher levels of genetic vulnerability for adult depression.
The cerebral cortex is important for memory, thinking, attention, and information processing. It is an outer, folded, and comparatively thin “gray matter” layer of the brain.
Researchers have developed a new and more environmentally friendly chromatographic technique for the analysis of methylxanthines in commercial brands of tea.
