Truth: Everyone has different sleep needs. There is absolutely nothing magical about the number eight. The amount of sleep we need at night to feel alert during the day varies from person to person. For some, it may in fact be eight, but for others that needed number may be six. The key is to figure out your individual sleep needs and not to stress about needing exactly eight hours of sleep each night. You can figure out your individual sleep needs based on how many hours of sleep lead to you feeling rested and restored the next day.
