Let us suppose that you get the recommended amount of sleep (8 hours) every night for your entire life. I know that you don’t always sleep the same amount as a baby, teenager, or elderly person, but let’s assume for the sake of argument that you do.

If we take the average lifespan of the American, around 78 years, this means that given our assumptions, by the time you are ready to return your biological content to the Earth, you have slept away 277,760 hours, or 26 years of your life.
