Michael discovers his long-time penchant for an early night could have some real health benefits. If you are someone who could go to sleep earlier and simply put it off with an extra episode or phone scrolling, Michael recommends going to bed an hour earlier than normal because getting enough sleep deeply impacts your brain, protecting against depression and other neurological problems. Professor Esra Tasali at the University of Chicago's Sleep Centre, shares her research that sleeping an extra hour a night has been found to have an incredible effect on our appetite, reducing cravings often linked to weight gain. Our volunteer Dylan, who is very health and exercise conscious, is surprised to find a little more sleep every night could benefit his fitness routine.
