Are you getting enough sleep? How do you feel when you wake up? It turns out how you sleep says a lot about your personality and how you feel at the start of your day. Professor Chris Idzikowski, director of the Sleep Assessment and Advisory Service, analysed six common sleeping positions and found that each is linked to a particular personality type.

No matter what your sleep position, Harvard Business School Associate Professor Amy Cuddy says sleeping in a fetal position can make you less confident because it's a lower power position.

To counter-act the potential effect of the sleep position on your emotions, she says you should take the time to either stretch out in a confident position before leaving your bed or strike a powerful pose before leaving for work.
