Different Ways Of Sleeping
I found this really interesting. Especially because one of my goals for 2016 is better sleep.
My original belief was that a solid 7-8 hours sleep every night was necessary for optimal performance, but I'm always open to have my beliefs challenged.
So it seems there are alternative sleeping patterns available that some people follow very effectively.
Many of us will be aware of the 'bi-phasic' sleeping pattern, common in Mediterranean countries and you'll know it as the 'siesta'.
There are 3 more alternatives here that might be less familiar. I confess I don't know anyone who functions using these less common sleep patterns. Perhaps you do, or you are one of them. I'd love to hear from you about how well it works, in the comments below.
However I do know that adequate sleep, however it is achieved, is essential for optimal performance whilst awake.
