We know that when we go a night without sleep it is more difficult for us to focus on difficult tasks and we have the feeling that remembering things is more complicated. Experts in the study of sleep have described its different phases, and have described that slow wave sleep is relevant for the consolidation processes of episodic memory. Consolidation is the phenomenon that allows memories to be fixed in long-term memory.
Researchers at the University of Rochester (USA) have carried out a study that demonstrates the restorative nature of sleep and that could explain why we need to sleep, according to the journal Science in its latest edition.
People who sleep more than 9 hours a day experience a cognitive decline much faster than those who only iron the hour for a period of 6 to 8 hours a day, according to a study just published in the journal 'Journal of Psychiatric Research '.
Scientists from the University of Michigan (USA) suggest that those who suffer from sleep apnea or difficulty breathing normally at night look worse and are considered less attractive.

Spanish scientists have discovered that the consumption of melatonin helps regulate weight gain because it stimulates the appearance of "beige fat", a type of fat cell that burns calories instead of storing them.

According to a recent study by Kimberly Fisher, from the University of Oxford (United Kingdom), and published in the journal Social Indicators Research, in most countries the average time spent sleeping ranges between 8 and 8.5 hours a day, adding a total of 56 to 60 hours of sleep a week. The sleepiest are the Bulgarians and the French, who sleep about 9 hours a day.
On the eve of an exam it is common to hear that it is better to go to sleep than to spend the night awake studying, since sleep serves to consolidate what has been learned. Memory enhancement at night had already been scientifically proven, but new research from Brown University (USA) has revealed that this brain activity occurs during the slow wave sleep phase and not during REM phase.
Neuroscientists at the University of California at Berkeley (USA) have shown that spending a sleepless night makes us crave donuts, pizza and other dishes classified as "junk food". The finding provides a new explanation for the relationship between sleep and obesity.
