Ask someone why they sleep and they are likely to reply: "Because I'm tired of course…" Ask them why they are tired and they may reply: "I haven't had enough sleep…"This shows the importance of the relationship between sleep and being awake.
So why do we sleep? Could we do without sleep allowing us to work longer without our health suffering?
Sleep is not a luxury that we can do without. Without sleep our bodies, minds and lives suffer. It is impossible to live without sleep.
