A scientific review published in *Brain Medicine* suggests that the eight-hour sleep rule does not suit everyone. According to some studies, the optimal amount may range from 6.4 to 7.8 hours, with needs varying by age and individual. Too little or too much sleep is associated with health risks, including heart disease, stroke, cognitive decline, and obesity, though the link between sleep duration and poor health is not settled. Sleep timing and regularity also affect health, and making up for some lost sleep over the weekend may help. The most important advice, however, is to get enough sleep without worrying excessively about the occasional bad night.
