You don’t have to be Hamlet to wax poetic on the wonders of sleep, but several new studies are giving us more insight into your nightly snooze. Although you may think sleep is just a way for your body to rest and recharge, the following researchers are showing that there is so much more to it.

Sleep deprivation may increase hunger

According to a presentation given at the American Heart Association’s annual conference, people tend to consume more calories on the day after they’ve had less sleep. Researcher Marie-Pierre St-Onge, PhD, found that women consumed, on average, 329 more calories when sleep deprived; men consumed 263 more. In addition to eating more calories, individuals also tended to consume foods with a higher fat and protein content than they did when they had adequate amounts of sleep. Though it may seem that participants were looking for quick sources of energy, if could also be that sleep impairs one’s ability to make healthy food choices.

Dreaming about a task may be beneficial to learning

Scientists are finding more evidence that dreaming about a particular task may be associated with better performance in that particular activity. Researchers are finding that dreaming is an essential part of understanding, organizing, and retaining the information we learn during the day. Harvard researchers found that college students who dreamt about a computer maze task they encountered during the day showed a tenfold improvement in their ability to navigate the maze than did those who did not dream about the maze.

Your social life may have an impact on your sleep schedule

Information collected at the University of Chicago found that people who report higher levels of loneliness also tend to report more sleep fragmentation. Those who feel more connected to others tend to get a better night’s sleep.

 

Sleep seems to have a positive impact on so many aspects of life. In what other settings have you noticed sleep’s influence on an individual’s functioning?
