Getting sufficient sleep is key to maintaining a sound mind and body. It is one of the ways to minimize the risk of several illnesses and to keep weight gain at bay.
But how much sleep is too little or too much? Or rather what is the ideal amount of shut-eye one should aim for? While most people would say 8 hours, a recent study conducted by a team of researchers from the University of Cambridge in the UK and Fudan University in China found that seven hours of sleep may be the ideal amount of sleep for middle-aged and elderly people.
