The rationale for the seemingly anomalous reference to a top is explained by Anne Baker in Glossary of Northamptonshire Words and Phrases (1854): A top sleeps when it moves with such velocity, and spins so smoothly, that its motion is imperceptible. Likewise, when a Yo-Yo spins swiftly at ...
The Coming Arctic Outbreak, Explained Just how cold is it likely to get this month? Possibly the coldest it’s been in years. Elliott Davis Jr.Jan. 3, 2025 Global Elections to Watch Numerous countries will hold elections in 2025. Here are the five to watch. Aneeta Mathur-Ashton Jan. 3...
The probability to fall asleep is explained by the interplay of processes S and C. Understanding the physiological mechanisms of both processes and examining the dynamic response of the model to challenge (e.g., sleep deprivation) has been a major focus of sleep research during the past 30 ...
People in poorer nations could lose more sleep, as it’s harder for them to get cooling machines.” he explained. The studies have also shown that rising temperatures hurt health, including increasing the possibilities of heart diseases, mental health problems, accidents and injuries. They have ...
No difference was found regarding light exposure between chronotypes. In conclusion, sleep parameters revealed poorer sleep quality in E-types for both the night and day shifts. These differences could not be explained by sleep opportunity, light exposure or activity levels. This study challenges ...
(e.g., Spain or Italy)41. Far East countries, Japan in particular, have been noted to report less sleep10,11. This could be partly explained by the work culture in these countries, Japan being the only nation in the world in which 25% of employed workers work more than 50 h per...
each participant would randomly win either the face or the maze game. This randomization ensured that any potential reactivation during sleep would be primarily explained by one of the games being successful (i.e., reward status), and not by some unforeseen resemblance between sleep-related activ...
Our results remain qualitatively the same, which suggests that neither selective migration nor seasonal confounders fully explained our estimates. However, Panel M suggests some interesting findings. When restricting our source of identification to spatial differences in sunset time within individuals (that...
To explore whether responsiveness during sleep could be explained by an ongoing, richer cognitive state before stimulation in nonlucid participants (NP and HP), we computed electrophysiological markers known for distinguishing high versus low cognitive states34,35. These markers were previously shown to...
Researchers and school officials explained the study to the parents, obtained their informed consent, and provided them the questionnaires. Parents completed the questionnaires and mailed them to a data entry company. Data received from December 2009 to the end of April 2010 were considered valid. ...
