Is the traditional 8 hours sleep myth outdated?

It’s long been stated that we should be sleeping for 8 hours every night. But research into sleep cycles suggests each of our cycles lasts 90 minutes. You should aim to sleep in multiples of an hour and a half so you don’t interrupt a cycle half way through. Waking at the point of deepest sleep will cause feelings of incomplete or not enough sleep, drowsiness and could affect your whole day.
