Looking to catch up on the latest discussions and research in the world of shuteye? I've got you covered. 

Working from your couch can be stressful 

Based on data collected from 15 nations, the United Nations International Labour Organization found that employees who work remotely (both occasionally and all the time) tend to be more productive, but also report higher levels of stress and insomnia, than "traditional" on-site workers.

Bio, calc, nap class 

Schools across the country are incorporating naps into teens' class schedules, to help them make up some of the sleep they're not getting at night and give them a midday break from their otherwise packed days. [WSJ

Mad chill people might not sleep well under stress

Certain positive emotions are more conducive to getting a good night's rest during periods of high stress than others, according to researchers from UC Irvine and Carnegie Mellon. Specifically, they found that college students brimming with vigor and pep rested better during final exams than those who tended to be calm and content.

Sick and tired

UK researchers analyzed genetic info from 111,749 people who answered questions about their levels of tiredness, overall health and cognitive functioning. Researchers found a link between feeling tired and being prone to (but not actually having) certain diseases, including diabetes. But, overall, genetics only accounted for a small percentage of the differences between participants' self-reported tiredness levels. Environment emerged as the primary determinant of being 'zausted.

Tired and sick

A study from the University of Washington involved 11 pairs of identical twins with different sleep patterns. Across the board, the twins who slept less than their other halves showed suppressed activity in white blood cells (suggesting weaker immunity). The study, while not a shocker, builds on previous work linking sleep and immune function. [University of Washington]

Aww, dogs sleep to remember, too (probably)

We've known for a while that sleep facilitates memory consolidation (the process of converting newly learned information into long-term memories) in humans. Now, Hungarian ethologists have preliminary evidence that sleep plays a similar role in boosting recall in our four-legged pals. [Van Winkle's]

Melatonin labels are peddling alternative facts 

The actual amount of melatonin in a supplement may differ significantly from what's listed on the label, according to a new study from the University of Guelph in Ontario. Researchers tested 31 different supplements and found at least a 10-percent difference between the stated and actual melatonin content in more than half of the products. And, overall, supplements ranged from having 83 percent more melatonin than the label said to 478 percent less. [AASM]
