Although randomized controlled trials investigating the acute effect of cocoa flavanols are sparse, most of them point towards a beneficial effect on cognitive performance. Participants showed, among others, enhancements in working memory performance and improved visual information processing after having had cocoa flavanols. And for women, eating cocoa after a night of total sleep deprivation actually counteracted the cognitive impairment (i.e. less accuracy in performing tasks) that such a night brings about. Promising results for people that suffer from chronic sleep deprivation or work shifts.
We’ve scoured the earth in search of the places that are so quiet, so somnific, so designed to induce exquisite sleep that you actually come back rested. As a nation, we are sleep-starved. One in three adults in America do not get the minimum recommended amount of sleep each night. The scarcity of Zzzs is such a nightmare that the US Centers for Disease Control & Prevention labeled it a public health epidemic. So, instead of running yourself ragged on your next vacation, consider taking a “sleep vacation” instead.
