Did you know we spend roughly one-fourth to one-third of our life sleeping? Amazing, isn’t it? For example, in a 70-year lifespan, 17 to 23 years would be spent in sleep! Sleep duration varies by age. The ideal sleep amount for an average adult is between 6 to 8 hours. But, of course, optimum sleep length differs by individual.
