Sleep is the power source that keeps our minds alert and calm. Every night and/or while napping, sleep recharges the brain's battery. Sleep clears the mind by removing daily toxins. Sleeping well increases brainpower just as weight-lifting builds stronger muscles, because sleeping well increases your attention span and allows you to be physically relaxed and mentally alert at the same time.
A study in the UK found that a good night’s sleep is roughly the equivalent of 8 weeks of therapy or winning a jackpot of $250,000. It seems strange to measure the value of sleep in these terms, however with so many people not getting healthy sleep, researchers are looking for creative ways to communicate just how important it is.
